President’s ColumnAn Update on INCE/USA “C & C’s”Almost two years ago, at the time I wasbeginning my second attempt at serving as thePresident of INCE/USA, I wrote a President’sColumn entitled “Challenges and Changes in INCE/USA.” At the beginning of that column I noted thatone of the duties of the President of INCE/USA is toprepare this column twice a year for NNI. This willbe my sixth and final column in that capacity. Assuch, it is opportunity to provide you with an updateon some of the issues brought out in that columnfrom 2006 June as well as provide some reflectionson INCE/USA in general.One of the issues very real to me has been the twoyearterm for the INCE/USA President. This changein the length of the President’s term began in 2006 asI took the office. I am convinced it is a good change,and one that will serve the organization well in thefuture. Having now done both, one year seems likejust too short of a time to learn the job and to beeffective in it. A definite key to the success of thetwo-year term being a doable job is the effort put inby the INCE/USA officers and committee chairs.Their leadership and effectiveness in getting thingsdone is certainly what moves the organization andmakes the President’s job manageable. During myterm, INCE/USA and I both have been fortunateto have had a strong cadre of officers and chairsin place. Hopefully, this level of support will beavailable to future Presidents as well.INCE/USA was very fortunate to have Joe Cuschieristep up and fill the executive director position. Withhis knowledge of the organization as a past INCE/USA President and his phenomenal dedication to thejob, this has been seamless and positive transition.I thank Joe for all of his continuing efforts andparticularly, all of help he has been to me.move to electronic publishing of NCEJ and otherINCE/USA material. Aiding these have been theefforts of the INCE/USA Treasurer (Steve Marshal)and Finance Committee Chair (Nick Miller) whoworked to make our budgeting and accountingmore understandable and visible to assist the Boardof Directors in making financial decisions. Eventhough the financial situation does not look bad now,the INCE/USA leadership needs to remain diligent inmanaging and reducing ongoing operational costs.Through the efforts of the NCEJ Editor (CourtneyBurroughs), you may have noticed improvementsin the timeliness Journal issues and an increase inpapers. To improve NCEJ international accessibility,the INCE/USA Board recently approved the conceptof individual subscriptions to persons outside ofthe US. As we advance NCEJ as the internationalpublication for noise control engineering, yourcontinuing support remains critical.On membership, the good news is that we arenot losing members overall, and the bad news isthat we are not gaining either. Besides retainingcurrent INCE/USA membership with the mostservices possible, we have two primary goals fornew members. The first is reach and recruit morestudents. The second is to reach and attract someof the large number of engineers working in noisecontrol who have yet to form an association withothers active in the field.In closing, I thank all of the INCE/USA Officers,Directors, Committee Chairs, and staff for yoursupport and efforts during the past two years. Iknow the President-Elect, Patricia Davies, will alsobe appreciative of your support in the coming twoyears.NNIPaul Donavan2006–2007 INCE/USAPresidentTwo other areas I mentioned in the last “C & C”column were finances and publications. I am happyto report that both of these are going well.

2006 Global Noise Policy Workshop IIIHonolulu, Hawaii4 December 2006A fourth Global Noise Policy Workshopwas held during INTER-NOISE 2006 inHonolulu, Hawaii, on Monday, December4. The theme of the workshop was“Implementation and Enforcement ofNoise Control Policies.” William W. Langand Tjeert ten Wolde were co-chairs of theworkshop.Progress toward acousticalreform of American schoolsDavid Lubman, FASA, Westminster, CA92683If OSHA won’t lead, perhaps itshould follow!Robert D. Bruce, CSTI Acoustics, TexasSupport to Health program includes aproject on communication dealing withthe development and implementationof a strategic communication plan. Italso includes a project on “influencinginternational, national, regional and localbodies responsible for rules and guidelinesconcerning environmental noise.”The workshop featured morning andafternoon sessions with presentations byexperienced engineers from countriesaround the world. Summaries of the panelpresentations and discussion for the firstand second sessions of the workshop werepublished in the June and September issuesof this magazine. This issue contains similarinformation on the third and final session.Panelists spoke on the development,implementation, and enforcement of noisecontrol regulations in their country at local,state, and national levels.The following presentations were madeduring the third session of the Global NoisePolicy Workshop. A discussion sessionfollowed. Summaries of the presentationsas well as a summary of the finaldiscussion are included in this article.Strategies for engaging cityplanners in the creation ofhealthy soundscapesKjell SpångKS miltek, SwedenBuilding noise policy In KoreaHee Joon EunKorea Research Institute of Standards andScienceStrategies forengaging cityplanners in thecreation of healthysoundscapesKjell SpångKS Miltek, SwedenIntroductionSoundscape Support to Health is acomprehensive 8-year research programaimed at development of the scientificbasis, methods, and models for creationof health-supportive soundscapes inresidential and recreational areas exposedto traffic noise. It is mainly financed by theSwedish strategic environmental researchfund – Mistra.Mistra requires that research programsthey support include strategies forcreating a bridge between the scientistson one side and the problem ownersand relevant decision makers on theother side. In addition to creation ofscientifically-supported solutions, thesuccess of a Mistra program depends onthe quality of the communication strategyand its implementation. The SoundscapeSoundscapes and CityPlanningThe goal of the communication project isthat the creation of positive soundscapesbecomes a natural element in city planning,including planning of new buildings,rebuilding of residential areas, planning ofrecreational areas, and traffic planning.Figure 1 at right illustrates the complexityand degree of efforts involved in a programfor achieving the attention of decisionmakersat all relevant levels.It is mainly activities at the local planningand decision-making level whichdetermine to what extent access to positivesoundscapes and limitation of traffic noiseis given priority and resources in practicalapplications. However, local decisionmakers and those involved in the planning,usually refer to directives, regulations, andguidelines from authorities on the regionaland national levels.CommunicationsThe communication program has beencomprehensive and run in parallel withthe research. It includes participating inmedia, turning to the general public—national and regional television and radioprograms, articles and interviews in138 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2007 December

attention from local, regional andnational decision makers and politicians.• Attention from national politicians is aprerequisite for bringing the subject tothe attention of international bodies.Building noisepolicy in KoreaHee Joon EunKorea Research Institute ofStandards and ScienceBackgroundKorea is a highly “condensed” country interms of both human population and socialinfrastructures. There are nearly 49 millionpeople in a land the size of Indiana wheremountains and hills cover 75 percent of theland. Koreans were aware of the potentialenvironmental impact of such natural andsocial constraints even during its relativelyearly development stage in the 1970s. In1980, Korea began an earnest effort forenvironmental protection and preservationby establishing the EnvironmentalProtection Agency as a vice-ministeriallevel government body. Although withthe developmental momentum, theenvironment had been deterioratinguntil the mid-1990s, Korea’s communityenvironment is now improving.Noise policy in Korea may be classifiedas either environmental policy orimplementation policy.Environmental Policy directs theadministrative action and defines theenvironmental goal of Korea. TheImplementation Policy stipulates the rulesand strategy for the realization of theEnvironmental Policy goals. The policiesare defined by the following laws.• The Basic Law for EnvironmentalPolicy (enacted by the Parliament)defines Korea’s Environmental Policyfor factors such as air, water, andnoise, and provides the legal basis forthe Implementation Policy to enablethe realization of the EnvironmentalPolicy goals.• The Regulatory Law for Noise andVibration (enacted by the Parliament)derives its legal authenticity from theBasic Law for Environmental Policyand covers areas of noise and vibrationproblems. This law stipulates policygoals for each area, as well as thegeneral plan to be undertaken by thecentral and local governments for therealization of this policy.• The Implementation Order for theRegulatory Law (Presidential Order)is not a law, but a Presidential Orderwhich stipulates detailed actions to beundertaken by the central and localgovernments in order to implement theactions stipulated by the RegulatoryLaw.• The Implementation Rules for theRegulatory Law (established by theMinistry) is not a law, but a MinisterialOrder which stipulates further detailedactions to be deemed necessary duringthe course of the execution of the Law.Evolution of Noise Policyin accordance with SocialDemandIn chronological order, the EnvironmentalPolicy for Noise was the first declared bythe Basic Law for Environment Policy,setting a framework for all other noisepolicies. The Law stipulates the goalof the Policy numerically in the form ofEnvironmental Standards for Noise asfollows:AreaClassificationGeneralAreaRoadsideAreaZoneClassificationZone AZone BZone CZone DZone A and BZone CZone DStandardsDay(06 - 22)50556570657075Table 1. Environmental Standards forNoise [Unit = L Aeq]Night(22 - 06)40455565556070The framework for the EnvironmentalPolicy comes from an ISORecommendation, but the details arebased on data obtained during a two-yearnationwide noise survey between 1981 and1982. The definitions of various areas andzones are given in detail in the Law—ZoneA includes exclusive dwelling sites, 50m range of schools or hospitals, andZone B includes dwelling sites with lightcommercial activities. The Noise Standardsare applied to road traffic noise only.For the purpose of supporting and realizingthe Environmental Policy, a series ofImplementation Policies were developed.Table 2 gives a brief history.In Table 2, each policy in the first columnis accompanied by a reference in thefourth column. These references are thenumerical targets for which each of thepolicies is applied and are specified in theLaw. These references may be classifiedinto the following three groups:• Environmental Standards are notregulatory limits applied to a specificindividual, but policy targets by whichthe central and local governmentsestablish the legal and administrativeframework to protect and preserve theenvironment. At the moment, there arethree Environmental Standards in Koreafor air, water, and noise respectively.These Standards also serve as a referenceguide for any technical activities relatedto environmental protection.• Noise Limits (Allowed EmissionLimit and Regulatory Limit). Unlikethe Environmental Standards, theLimits must be observed. TheAllowed Emission Limit is appliedat the boundary of factories or at aspecified location from vehicles. Thisis a source-control plan. The other,the Regulatory Limit, is applied at theboundary of the affected area. ThisLimit is intended to provide offenderswith some flexibility when noise isinevitable, such as in construction.The Allowed Emission Limit is morestringent than the Regulatory Limit.

Noise Policy and Related Laws in Chronological Orderany case, violation of the Limit mayincur penalties and disadvantages asprescribed in the Law.• Noise Range is applied in certaindesignated areas by the central or localgovernments for road traffic noise,railroad noise, and airport noise. Whilethe Noise Limit was intended to controlindividual sources such as industrialmachinery and vehicles, the NoiseRange protects areas from traffic noise.Because the Noise Range deals withtraffic noise and is applied to areas, nopenalty is imposed for failure to observeit. Still, the central or local governmentmust take action, either legal oradministrative, to protect the designatedzone from noise and publish the resultsperiodically for public review.• Product Noise Rating aims to providethe consumer with a means for selectingquieter products. It was initiallyintended to apply to home appliances,but there was strong opposition fromthe electronics manufacturers. As aresult, the Product Noise Rating isjust a recommendation for consumerproducts but is mandatory when appliedto construction equipment. By lawthis equipment, both domesticallymanufactured and imported, must carrythe Noise Rating Tag.ConclusionsNoise policy in Korea has evolved duringthe past 20 years, making it very systematicand comprehensive. The members of thepanel which assisted the government indeveloping various noise policies remainedalmost unchanged during that period. Thisenabled the panel to develop the policyin a very systematic and consistent way,minimizing conflicting factors amongdifferent policies and evaluating theworkability of the policy.As a late starter, Korea learned somevaluable lessons from the experienceof advanced countries, and adjusted itspolicy goals and implementation schemesaccordingly. Although the Koreanexperience may be unique and may not bereadily applied to other countries, the spiritmay be shared. Also, the principles setup during the course of establishing noisepolicy in Korea may be observed withequal validity by any nation that wishes toestablish its own noise policy.Progress towardacoustical reformof AmericanschoolsDavid Lubman, FASA,Westminster, CA 92683(This presentation is in the form ofquestions and answers.—Ed.)What progress has been made in schoolacoustical reform in the United States?American National Standards Institute(ANSI) Standard S12.60-2002 hasspecified acoustical performance criteria,design requirements, and guidelines forschools. Acoustical reform in schoolsis supported by the U. S. Access Board(Americans with Disabilities Act) andmany other professional organizations. Itis endorsed by the National Academy ofSciences National Research Council for“green” school buildings (2006), and hasbeen adopted by several states.Many of ANSI’s initial opponents in theHVAC and relocatable classroom industrieshave been won over; new, quieter productsare being developed for the school market.Weakened versions of S12.60 have beenadopted by CHPS (Collaborative forHigh Performance Schools) in Californiaand elsewhere, and CHPS stimulated adraft for Green Building Council’s LEEDguideline for green schools with CHPSlikeacoustical requirements (August-September 2006).How did the new policies come about?This began around 1997 with twoindependent actions:1. A populist uprising by AcousticalSociety of America (ASA) activiststo improve classroom acoustics wasfostered by a visionary acousticalconsultant, Buzz Towne. ASAsupported classroom acoustics activitiesthrough its Technical Committees(Architecture, Acoustics, Noise, andSpeech Communication.

Bruce, CSTIAcoustics, TexasNoise-induced hearing loss (NIHL) hasbeen an industrial problem in the UnitedStates for over 100 years. Governments,both state and federal, were slow to regulatenoise exposure. In addition, the authorityis scattered among a number of agenciesthat may have different regulations toaccommodate their particular industry.The following U.S. Agencies haveoccupational noise regulations:• Occupational Safety and HealthAdministration (OSHA) – oneregulation for manufacturing and onefor construction• Mine Safety and Health Administration(MSHA)• Coast Guard• Federal Railway Administration (FRA)• U. S. Department of DefenseThe current noise level limit for nonmilitaryworkers is 90 dBA with a 5 dBexchange rate, and for military personnel itis 85 dBA with a 3 dB exchange rate.Prevention in the form of hearingprotection is not assured, as workersmay not know how to properly wearthis protection and it may not alwaysbe available. Although the federalgovernment requires manufacturersto label their earplugs with the NRR(noise reduction rating), the NRR doesnot represent the typical noise reductionachievable in practice in the workplace.NRRs of 20-30 are common but fewworkers get more than 10-12 dBA of noisereduction using hearing protection duringtheir workday. Perhaps thegovernment should considera better labeling alternativeor a different approach toprotecting workers’ hearing.(The labeling requirement isbeing revised.—Ed.)When a worker suffers fromNIHL, it is usually familymembers who first recognizethe problem. Eventually the problem getsso bad that individuals can no longer denyit, and they see an audiologist or physicianto confirm that it is permanent hearing lossand often it is diagnosed as noise inducedhearing loss.Mild hearing loss is similar to mildasthma—annoying but not critical.As hearing worsens, it becomes likethe chronic pain of a slipped disc andeventually severe hearing loss can belikened to continuous pneumonia. Witheven mild hearing, one may not hearhigh-frequency speech sounds andmay not understand soft-spoken voicesin reverberant or noisy spaces (e.g.restaurants). The person often cannotmaintain conversations and, as a result,may give up on friendships because theycan’t hear well enough to carry on aconversation. Obviously, they can feelsocially isolated from others.At the beginning of the 20th century, about20% of the jobs were white-collar. Oftenworkers would move from noisy jobs toCivilian hearing losscompensation was 56million USD in 2003, andthat number is rising.quieter jobs in lower level management andeven to higher positions. At the beginningof the 21st century, about 60% of the jobswere white collar. There is an expandingopportunity for white-collar workers. Butif a worker has spent 10–20 years in anoisy occupation and has hearing loss, hisopportunity for a white-collar position maybe limited because almost all white-collarjobs require good hearing.As life spans increase, workers at age 50with extensive noise exposure will have“80-year old ears.” Whenthey reach 80 years, willthey have any hearing left?This is definitely a qualityof-lifeissue. Are we headedtoward an older, deafer,depressed male population?Unfortunately this is reallyabout money and whereit is spent. Currentlymuch of the spending is in the form ofcompensation after NIHL is diagnosed.Military compensation for hearing-lossdisability for veterans has amounted to $7.6billion over the past 30 years. Civilianhearing loss compensation was $56 millionin 2003, and that number is rising. Nonmilitarybenefits for workers are usuallycovered by Workers’ Compensation butmay vary by state and are likely to beless than $10,000. In addition, workerswith hearing loss have sued employersand third-party manufacturers of noisymachinery and equipment.Perhaps a new approach should be tried:spend the money before workers lose theirhearing by purchasing quiet equipmentand controlling noise at the source. Twomajor corporations whose expenditures onequipment and facilities exceed $15 billionnow have new limits on the noise levelof new purchases. Because current andextensive hearing protection programs havenot been adequate, industry must seriouslyconsider buying quieter equipment toprevent hearing loss in workers.

focus on 90 dBA for engineering controlsand 85 dBA for monitoring has not solvedthe problem. A recommended new limit fornoise exposure at one meter from the noisesource should be 80 dBA which mightresult in workplace sound levels of 85 dBA.Earlier I proposed the concept of theLifetime Occupational Noise Exposure(LONE) for workers. This is the soundexposure of a worker over his lifetime ofoccupational noise exposure—2,000 hours/year for 40 years. The sound exposure isexpressed in Pascal squared hours. A soundlevel of 85 dB for 2000 hours per year for40 years would be a sound exposure ofabout 10,100 Pascal squared hours.The use of Type 2 sound level meterssuggests that ±1 or ±2 dB is not veryimportant. Perhaps it isn’t when it is viewedas a single measurement. But when it isrepresentative of noise levelsexperienced for 2000 hours ayear for a working lifetime,it can be very important. Forexample, if a sound level of87 dBA (sound exposure ofabout 16,000 Pascals squaredhours) were misrepresentedas 85 dBA (about 10,100Pascals squared hours) dueto inaccurate readings, thesound exposure would be anexposure 60% higher! So 2dBA is important!It is time for OSHA andothers to establish standardsthat protect all workers andset these standards sufficientlylow so that companiespurchasing equipment thatcan last for 25-50 years willhave confidence that thisnew limit will not changeand that their workers willnot incur noise induced hearing loss on thejob. OSHA should join the internationalcommunity by using 85 dBA for an 8-hourexposure time with a 3 dB exchange rate.This can be a first step toward protectingOSHA should join theinternational communityby using 85 dBA for an8-hour exposure timewith a 3 dB exchangerate. This can be a firststep toward protectingthe hearing of workersand making the world asafer and quieter place.the hearing of workers and making theworld a safer and quieter place.DiscussionThe following is a transcription of thediscussion portion of Session 3. Thisincludes questions (Q) from the attendees,answers (A) of the panelists, and comments(C) from both attendees and panelists.Bill Lang chaired the discussion. Thediscussion has been grouped by topic,and is not in the actual order in which thediscussion took place.SoundscapesQ: Kjell Spång, please say more about thepositive impact of good soundscapes.A: We tend to talk only about the negativeaspects of our sound environment. Theinvestigation showed that we shouldspend more time explaining to citizensthat it’s healthy for them andgood for the development oftheir children if they live inan environment which has apositive sound environment.That is the message weshould put forth instead ofsaying that it’s dangerousto live in an environmentwith high noise levels. Ourprogram is developing whatwe call “green labeling” ofresidential environmentswhich would describepositive residential areas.C: (David Lubman) Whenmany of us leave our jobs inthe city to take a vacation ina quiet area, in the countryperhaps, after a few dayswe become used to theambience, and we can hearagain the sounds of nature.This is a healing experience.C: (Kjell Spång) Yes. In this program wehave investigated how the characterof the areas around dwellings affectsthe residents’ rating of the soundenvironment. The results show aconnection. If you add a silent side to ahouse in a noise-exposed area, you willreduce the number of annoyed people.The situation can be improved if wealso address other aspects of the silentside. Access to “green” is important asis the ability to listen to positive soundslike birds, wind, and children playing.By organizing the living area, a lot ofpositive things may be added to thesound environment as well as mitigatingthe noise problem.Q: Kjell Spång, Sweden has the area inwhich to build new residences withsilent sides. How many countriesin the EU have that available area tobuild silent sides? In Sweden newconstruction is built with a courtyard inthe middle; that’s the silent side. Howmany other European countries builddwellings on that model?A: I don’t know how many countriesbuild with a courtyard in the middle.There is no problem to build silentsides in densely populated local areas.This might be done by closing thegaps between buildings, for example,in Sweden where the program hashad some influence, the gaps maybe closed by adding some new flatsto the building. It can be a win-winsituation—quieter with more availableflats in the same area. There is notnecessarily a conflict between a densecity and a good noise environment.C: (Hikeki Tachibana) The understandingof soundscape is very important. Inyour presentation, a soundscape is apleasing environmental sound situationrather than an area of annoying noise.In Japan and perhaps China and Korea,many insects make sounds during thenight; and we enjoy the sounds. But myfriend from the northern part of Europedoes not enjoy the insect sounds—noisy, very different. So the definitionof soundscape may vary.144 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2007 December

C: (Bill Lang) So the definition ofsoundscape may have a culturalinterpretation which one must recognize.C: (Kjell Spång) We define soundscapein our program as the sound variationin space and time caused by thetopography of the city and differentsound sources. We differentiatebetween acoustic soundscapes,which is what we can measure withour acoustical instruments, and theperceived soundscape where we needperceptual methods to measure thequality of the sound environment. Sothe definition of a sound environmentis a bit broader than that of asoundscape. The difference is that asound environment is a static situation,whereas the soundscape conceptincludes time variation as part of it. Iagree with you that there are differentinterpretations of soundscapes, andthat’s one of the problems that we havewith promoting positive soundscapes.When we talk with politicians or thecommunity people, they have difficultiesin understanding what we mean bysoundscapes. Sound environment iseasier for them because they are familiarwith the term environment.C: (Bill Lang) I don’t see any culturalelement in your definition. I think thatwas what Prof. Tachibana referred to.C: (Kjell Spång) Yes, that is the differencebetween the way we use it and theway some others do. Our approach ismore technical. The reason that weuse soundscape is that it goes beyondwhat we can measure with acousticalinstruments.Q: Kjell Spång, I’m curious about the silentside of buildings and whether there’sany economics to the annoyance that’sreferred to and the response of people.A: Part of our study is based on interviewswith many people living along the sameroad with the same traffic where someof the houses had access to a silent sideand some did not, depending on howthey face the street. We were able tocompare the effect; that’s where we getthe 50 percent figure. We investigatedfive different areas like thatand they went from 65 dBdown to around 50 dB onthe exposed side.C: (David Lubman) Thereare positive aspects tosoundscape that you mightconsider besides areasof quiet. We don’t wantsilence. When RachaelCarson wrote Silent Spring,the book that started themodern environmentalmovement, silence wasdeath. So silence wasn’tall that good. But thereare other things that,if the environment isquiet enough, you canhear. Things that bringpleasure and joy and thatare culturally related.For example, if it’s quietenough you can install a children’ssound playground so children can enjoyplaying with sounds and listening tothem. One example of the culturalaspect of a soundscape is in Englandwhere they have sound neighborhoods.When the Church of Bow Bells(Church of St. Mary-Le-Bow) wasbuilt in London, its bells created asound neighborhood. Everyone inhearing range of the bells lives in thatsound neighborhood. That defined theCockney ethnicity and anyone bornwithin the sound of Bow Bells was aCockney. Some nursery rhymes arebased on this, e.g. “Oranges and lemonssay the bells of St. Clemens.”C: (Kjell Spång) This program isinterdisciplinary. We have acousticians,medical personnel, and psychologists.The psychologists are best qualified todefine positive soundscapes, and theyWhen we talk withpoliticians or thecommunity people,they have difficulties inunderstanding what wemean by soundscapes.Sound environment iseasier for them becausethey are familiar with theterm environment.have developed a system of perceptionmeasurements based on technologyusing neural metrics. This study hasalso included aspects of social lifein residential areas. There is littlesocial life if one cannot beoutdoors in a reasonablypleasant environment.C: (Bill Lang) This relatesto an aspect that we talkedabout earlier today, namelythat the FAA in this countryis spending something likeUSD 500 million a year onsound insulation of housesaround airports, but thatdoesn’t allow the individualto use the backyard for asocial gathering outdoors.We are sealing the housesbetter, but they have to stayindoors to enjoy the quiet.Cardiovascular Diseaseand Ototoxic ChemicalsQ: Bob Bruce, whatare your thoughts aboutthe growing scientificevidence of other health outcomes ofoccupational noise exposure such ascardiovascular diseases and accidents?What is the impact of this newknowledge on exposure limits?A: I don’t have a lot of experiencein that area. We’ve looked at thecombination of noise and chemicals;the double exposure seems to enhancethe likelihood of problems. Hearingloss can occur at lower sound levelswhen one is exposed to chemicals.Although I haven’t seen evidence thata combination of noise and vibrationmay cause cardiovascular disease, somesuggest that this is possible.Office Masking NoiseQ: Bob Bruce, in addition to what youreported about office workers, haveyou considered the impact of officemasking noise?2007 December www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org145

A: That’s a good point. I’m from Houstonand Houston is hot. So the buildingsare air conditioned. If you were toput sound masking in its place, peoplewould stand underneath it thinking itwas air conditioning. We’ve got to havethe AC noise to know that we’re cool.Some office cubicles might be 6 ft by8 ft with a partition as low as 5 ft or ashigh as 6 ft or 7 ft, and the backgroundnoise varies considerably. Some placesdon’t have any background noisemasking systems, and you learn to dealwith it. Others have masking systemsthat are in the 45 dBA range.C: (David Lubman) Consider an officethat uses background masking noise tosustain their use of open-plan offices.This is really a low-cost way of fillingan office so that the number of workersper square meter is largest and the costfor the owners is lowest. But even ifthey use the lowest level of maskingnoise that’s usually recommendedwhich is 45 dBA, the average speechlevel of office workers is 50 dBA.That means that at a distance of onemeter, the speech to noise ratio is only5 dB. Is that enough? The owners arepaying the price for this in reducedproductivity and might reconsider ifthey knew they were not saving asmuch money as they thought.OSHA and FRA RulemakingQ: Bob Bruce, what do you see as thebiggest barrier to getting OSHA to leadas opposed to follow?A: I don’t know, it’s a difficult problem.The Federal Railway Administration(FRA), in a unique moment in history,revised its rule. They put out a Noticeof Proposed Rule Making and manyresponded, including the NationalHearing Conservation Association anda number of individuals. Although therespondents advised 85 dBA with a 3dB exchange rate, the FRA decidedagainst it and documented the decisionwith over 130 pages of explanationsprinkled with names like Ted Schultzand Elliott Berger who urged them toadopt the 85/3 dB rule. My opinionis that they didn’t have the courage togo against OSHA directly. But, whileOSHA has an absolute cut-off of 115dB for 15 minutes of exposure, inlocomotive cabs the rule permits up to120 dB but only for 5 seconds. It’s asif somebody said, “The horns will blowfor short intervals so we’d better get thatnumber up.” But FRA did do a numberof good things, e.g. they forced in airconditionedcabs. The railroads foryears said they could not air-conditioncabs. In the 1980s, the railroads saidit was impossible.But then a Canadianlocomotive was air-conditioned. Thatis amusing, but in the late 1930s therailway passenger cars had a new thingcalled air-conditioning. And one of thereasons they did it was to reduce thenoise inside the passenger car.Toward a Global Policy on NoiseQ: To the panel. How can the differentcontributions of this workshop be usedto move toward a global policy on noise?What is the relationship between thisworkshop and a global policy on noise?A: (Bob Bruce) The one place wherewe’ve had progress is in the schoolsituation; we’ve taken a giant stepforward in making schools better.Perhaps we could figure out how toapply that to other areas. Nick Ashfordfrom MIT’s policy program said thatthe problem with noise is that the noiseinside factories does not get linked toanything that’s perceived as important.C: (Bill Lang) Where do we go fromhere? Our series of global noise policyworkshops has become more focusedon specific topics. Today we focusedon implementation and enforcement.We will focus on other areas in ourfuture workshops. We have to developan action plan, and that action planmust involve the NGOs because theyrepresent the public. If we don’thave the public, then we cannot putpressure on government authorities todo something about noise. The morethan forty I-INCE Member Societiesare part of the action because they areall NGOs, and we would expect them tobe founding members of a worldwideorganization of NGOs that are unitedin this effort. Then it must be movedinto an international advocacy positionto force something to happen at thetop. Whether it will take 5 years or fivedecades is impossible to predict.C: (Samir Gerges) This workshop isvery informative and provides a lotof information. But there are notmany people from South America,China, India, and some other countriesparticipating. And we need to involvelocal authorities. What we propose maylook good on paper; but if it’s a matterof local policy, it is important to involvepeople in those agencies to participate.C: (Bill Lang) But it is not just localpeople. There are national and internationalissues that must be addressed.C: (Samir Gerges) Yes, I can see that.In Asia the problem is much biggerbecause, for example, in Hong Kongthere are only about 300 square milesof area in which 7 million people live.In Sweden they have the luxury ofmore than 173,500 square miles with 9million people, and they can enjoy whatis unthinkable for those in Hong Kong.In Brazil we have a similar problem.Therefore, it would be interesting tohave other countries participate.C: (Bill Lang) Absolutely. When we getto the international advocacy stage, wemust have all countries of the worldrepresented. Today there are over 200members in the United Nations. Thiswould compose an international advocacygroup where all countries are representedand the cultural, geographical,and ethnical differences between themwould be taken into account.146 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2007 December

C: (Tjeert ten Wolde) Today we havediscussed many aspects of noisecontrol, for example, the soundscapes.It is doubtful whether the concept ofsoundscapes at the global level shouldbe pursued. But product noise emissioncould be approached at a global level,and it would not be necessary to includerepresentatives from local authorities—just representatives from industry.Another aspect which may be discussedat the global level is definitions. It is ahandicap in our profession to have somany different noise indices all over theworld. If we can agree at a global levelto use the same vocabulary to describea certain effect, that would facilitatecommunication and the possibility tolearn from each other.C: (Kjell Spång) I agree that emissionshould be brought up at the internationallevel. In order to achieve good noiseenvironments, something must be donewith emission. We cannot solve theproblems solely from the immission side,so it is important for us on the internationallevel to deal with emission issue.As this can be political, we must havetwo strategies: first, a strategy for thedevelopment of a global policy involvingall countries and which is favorable toeveryone, and second, a strategy to reachthose who can implement the first strategyon an international (political) level.of products that are creating thecommunity and occupational noise.The difference between emission andimmission is understood by engineersbut difficult for politicians.Q: Bill Lang, when you mentioned anaction plan, did you mean a plan whichis applicable for all countries or are youthinking of a framework for a strategywhich can be adapted to the individualneeds of each country?A: The latter, but it is the immission criteriathat must be selectable by theU.N. member countries depending ontheir cultural, ethnic, geographical, andhistorical perspectives. In emission itmust be the same throughout the world,and that’s why we need a global noisepolicy on emission because productscan be made quieter. As mentionedearlier, it’s easy to air-condition locomotivecabs; but the manufacturers oflocomotives in North America said itwas impossible until the Canadians didit. If we allow manufacturers to say it’simpossible to solve a problem technically,we will not have a quieter world.C: (Tjeert ten Wolde) It is not theintention of this action plan to developa guideline for national authoritieson every aspect of noise control as amodel for countries to implement. Itis the aim to select those items whichcan best be handled at the global leveland which will improve the possibilityof quieter domestic and occupationalenvironments worldwide.C: (Bill Lang) Where are we going? Howdo you integrate a dozen differentpresentations into an action plan? Theanswer is you don’t because you have tobuild on a large number of workshopsto look at all aspects of the problembefore you can develop an actionplan. We have to walk before we canrun. That is our plan here, and this iswhat the new TSG 7 will be workingtowards—developing an action planthat will contribute to making this aquieter world.NNIC: (Bill Lang) We are far from being ableto distinguish between emission andimmission at the political level.C: (Kjell Spång) But you can talk aboutthe noise from cars with politicians; youdon’t have to use the term emission.C: (Bill Lang) The problem is that wehave immission criteria in communitynoise and immission criteria inoccupational noise, and the noiseswe are dealing with are producedby machines which are rated on anemission basis. We need regulatoryaction to reduce the emission levels2007 December www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org147

International INCE Technical Study GroupsAlan H. MarshI-INCE Vice President — Technical ActivitiesIntroductionThe principal technical activities of I-INCEare carried out by I‐INCE TechnicalStudy Groups authorized by the I-INCEGeneral Assembly on recommendationof the I-INCE Board of Directors. Othertechnical activities were described inthe 2002 December issue of NNI. Thefollowing is a brief history of the formationof the I-INCE Technical Study Groups, anda summary of the activities of each group.More details may be found on the Internetat www.i-ince.org.In recognition of the need to address noiseissues of international interest, the I-INCEBoard of Directors, at their meeting duringINTER-NOISE 91 in Sydney, Australia,took the first step to enlarge the scope ofthe activities of the General Assembly.The following year at INTER-NOISE 92in Toronto, Canada, the General Assemblyestablished technical work on two topics:“Upper Limits for Noise in the Workplace”and “Noise Emission of Road Vehicles.”I-INCE Working Parties were convenedand I-INCE Technical Reports wereprepared and published on those twoimportant topics [97-1,01-1].Additional I-INCE technical work wasestablished by the General Assembly atINTER-NOISE 94 in Yokohama, Japanon two additional topics: “Effectivenessof Noise Walls” and “Community Noise.”An I‐INCE Technical Report fromthe study of the effectiveness of noisewalls was published [99-1]. Work on areport concerning community noise wasterminated after a few years because oflack of progress.Formal guidelines for carrying out thetechnical work of the Institute were drafted,and, after several revisions, were adoptedby the General Assembly at its meetingduring INTER-NOISE 98 in Christchurch,New Zealand. These guidelines are givenin Part 2 of the I-INCE Rules and areavailable on the I-INCE website.Technical Study GroupsAt the meeting of the General Assemblyduring INTER-NOISE 99 in FortLauderdale, Florida, USA, it was agreed toestablish Technical Study Groups 1–4 withthe scopes and objectives described in thestatus reports given below.Technical Study Group 5 was establishedby the General Assembly during INTER-NOISE 00 in Nice, France.Technical Study Group 6 was establishedat the meeting of the General Assemblyduring INTER-NOISE 03 on Jeju Island,Korea.Technical Study Group 7 was establishedby the General Assembly during INTER-NOISE 05 in Rio de Janeiro, Brazil.Technical Study Group 8 was establishedby the General Assembly during INTER-NOISE 06 in Honolulu, Hawaii, USA.Status of I-INCE TechnicalStudy Groups as of 2007NovemberDescriptions of the work of the I-INCETechnical Study Groups are given below.TSG 1 — Noise of RecreationalActivities in Outdoor AreasObjective and statusThe work of TSG 1 deals with noisefrom recreational activities in outdoorareas. Recreational activities are thosepursuits outside one’s regular occupationthat are usually engaged in for purposesof relaxation or leisure-time after work.Noise associated with many recreationalactivities can be annoying and disturbing.A draft of the report from TSG 1 hasbeen prepared and is under review. TheConvener is Philip Dickinson.TSG 2 — Noise Labels forConsumer and IndustrialProductsObjective and statusThe work of TSG 2 dealt with noiselabeling for consumer and industrialproducts. Consumer goods are those soldat retail to ultimate customers for personalor household use, indoors or outdoors.Industrial products are sold to commercialfirms for a wide variety of purposes. Inmany parts of the world, consumer andindustrial goods are sold without anylimits on noise emission, frequently withno indication to the purchaser of hownoisy the products will be when installed,either to those who operate the productsor to those in the vicinity of an operatingproduct.After several years of efforts, the Boardof Directors and the General Assemblydecided during INTER-NOISE 06 that thework of TSG 2 should be terminated andthe TSG disbanded with thanks.The Convener of TSG 2 transmitted the148 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2007 December

material that had been gathered on noiselabels to the Co-Conveners of TSG 7for possible use by that Technical StudyGroup. The Convener was Bernard Berry.TSG 3 — Assessment ofthe Effectiveness of NoisePolicies and RegulationsObjective and statusThe objective of TSG 3 is to collectinformation about noise legislation andregulations in countries around the world.During the last half of the 20th century,many countries recognized noise as anenvironmental and occupational problem.Regulations and guidelines were developedfor limiting the exposure to noise and forimplementing noise-control technologies.A preliminary draft of a report from TSG3 was circulated on 2007 July 09 to theSecretariats of the Member Societies forreview and comment. The preliminarydraft will be revised and circulated to theMember Societies as the first CommentDraft in accordance with the procedures inPart 2 of the I-INCE Rules for the technicalwork of the Institute. Co-Conveners areHideki Tachibana and William Lang.TSG 4 — Noise andReverberation Control forSchoolroomsObjective and statusThe objective of TSG 4 was to preparean I-INCE Technical Report withrecommendations for acoustical criteriaand noise-control features that maybe applied in the design of all types ofenclosed learning spaces in order tooptimize the learning experience forteachers and students. Learning spacesinclude any enclosed area where studentsand teachers interact for educationalpurposes. Principal acoustical criteria arethe level of the background sound and thereverberant quality of the learning space.The work of TSG 4 began in 2000with Zerhan Yuksel from Turkey as theConvener. A draft of a report was initiatedand some progress was made over thenext few years. Because of increasedresponsibilities at the University whereshe is employed, Mrs. Yuksel resigned in2003 as Convener and a new Convenerwas appointed–Carsten Svensson ofSweden. The first meeting of TSG 4with Mr. Svensson as Convener was heldduring INTER-NOISE 04 in Prague, CzechRepublic. No progress on the report wasmade in 2005 or 2006.At the meetings of the Board of Directorsand the General Assembly in 2006December in Honolulu, it was proposedthat the work of TSG 4 be terminatedand the TSG disbanded because of a lackof progress. A decision to terminate thework of TSG 4 was taken at the meetingsof the Board of Directors and the GeneralAssembly in 2007 August in Istanbul. TheTSG was then disbanded with thanks.At the 2007 August meeting, the Boardand the General Assembly accepted theproposal from Carsten Svensson to reestablishTSG 4 with a new scope and newmembers to be appointed by the I-INCEMember Societies subject to submittal ofa revised scope that will concentrate onpreparing an I‐INCE Technical Report onthe effects on the learning experience ofhigh levels of sound as well as the effectsof poor acoustical conditions in classroomsand other school rooms. Members willbe appointed after the revised scopeis accepted and formation of the reconstitutedTSG 4 is approvedTSG 5 — Noise as a GlobalPolicy IssueObjective and statusThe objective of TSG 5 was to preparean I-INCE Technical Report dealing withnoise as a global issue in contrast withnoise as a local issue. A major objectivewas to describe what is needed to createeffective global noise-control policies.The final report from TSG 5 was publishedin the 2006 September-October issue of theNoise Control Engineering Journal, and isavailable on the I-INCE web site [06-1].With publication of the final report, thework of TSG 5 was complete and the TSGwas disbanded.TSG 6 — Community Noise:Environmental Noise ImpactAssessment and MitigationObjective and statusThe objective for TSG 6 is to preparean I-INCE Technical Report that givespractical guidance to policy makers whoare involved with regulation and control ofcommunity exposure to noise, excludingthe sounds generated by neighbors. Theemphasis of the report will be on how anenvironmental impact analysis process canbe an integral part of an effective strategyfor control of community noise, with landuse planning as an essential element of thecontinued on page 1602007 December www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org149

Overview of INCE/USA Technical ActivitiesStephen HambricINCE/USA Vice President — Technical ActivitiesStephen Hambric of the PennsylvaniaState University (sah19@only.arl.psu.edu) is now Vice President of TechnicalActivities for INCE/USA and chairs theTechnical Activities Board, comprised ofthe Technical Activitiy Committee Chairswho help: 1) produce special sessions atINCE/USA conferences, and 2) identifypromising papers for and organize specialtheme issues of Noise Control EngineeringJournal (NCEJ). Associated with theChairs are 13 committees.

Surveying and psychoacoustic testingtechniquesExperimental Techniques andInstrumentationChair: Jason Kunio(Jason.kunio@bksv.com)Committee Members: W. Steve ShepardJr., Wen L. Li, Todd RookThe committee acts as a forum forthe dissemination of information andresearch results on experimental andinstrumentation methods in the fields ofnoise and vibration control, and acoustics.This forum is established through periodicmeetings at NOISE-CON and INTER-NOISE conferences, sessions organized atthese conferences, and the organization ofseminars or short courses in conjunctionwith these same conferences. From theseconferences, the committee will work withthe Noise Control Engineering JournalBoard to identify papers of special meritfor inclusion in the Journal. In addition,the committee strives to provide aninterface to international and nationalgroups on relevant experimental andmeasurement procedures, facilitate thecoalition of divergent approaches to thesame experimental and measurementproblems, and act as a resource forthose seeking information on currentexperimental and instrumentationdevelopments.Transportation NoiseChair: Micah Downing (micah.downing@blueridgeresearch.com) andJudy Rochat (rochat@volpe.dot.gov)The Transportation Noise TechnicalCommittee will provide forums for theexchange of technical and regulatoryinformation related to the development andapplication of noise and vibration research,and methodologies to the transportationindustry. A major thrust of the technicalexchanges will be the integration anddissemination of applied research resultsinto the industrial community. Technicaltopics will cover noise and vibration tests,analysis and processes that are related tosurface transportation noise concerns fromcustomer and regulatory perspectives.Industrial NoiseChairs: Mike Lucas(Mike_Lucas@irco.com)The Industrial Noise Control Committeeprovides a forum for exchange of technicaland regulatory information related to themanagement of industrial noise. Areasof interest to the Committee include theapplication of programs, approaches,technologies, and products for controllingoccupational and community exposure tonoise generated by industrial processes,facilities, and equipment. In particular,the Committee seeks to do the following:(1) organize sessions for NOISE-CONand INTER-NOISE meetings; (2) sponsorspecialized workshops and seminars inconjunction with NOISE-CON conferencesor INTER-NOISE congresses; (3)encourage INCE members and others topublish, in Noise/News International andthe Noise Control Engineering Journal,case histories as well as accounts ofsuccessful programs and approachesrelated to the management of industrialnoise; (4) serve as an information exchangeand clearinghouse for members and othersinterested in the management of industrialnoise; (5) form alliances with otherprofessional and trade organizations whosecharters overlap or complement those ofthe Committee; (5) develop, provide, and/or advertise the availability of educationalmaterials for members and others to use intheir outreach and guidance programs.Community NoiseChair: Larry Finegold (LSFinegold@earthlink.net)Committee members: Frank Brittain,Bennett Brooks, Ken KaliskiThe Technical Committee on CommunityNoise (TCCN) was formed for the purposeof promoting the use of noise controlengineering technologies and adequatenoise management policies to reduce noiseexposure in communities across America tolevels necessary to adequately protect thehealth and welfare of the US population.To fulfill these objectives, INCE TCCNwill pursue the following general priorities:• Promote the development and useof state-of-the-art noise controltechnologies, including the provisionof information on these technologiesto the public and relevant governmentagencies• Promote sponsorship and conduct ofhigh-priority research on the effectsof noise, including health effects,community annoyance and sleepdisturbance research2007 December www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org151

• Support the development of up-to-datenational and local government noisemanagement and land use policies,including increased cooperationbetween industry, government and thepublic on noise control issues• Support programs to educate the publicon the adverse effects of communityand environmental noise exposure• Support the continued professionaldevelopment of the noise controlengineering field and promotion of theirservices to communities• Coordinate INCE/USA community noiseactivities with those of other nationaland international professional acousticsorganizations and government agenciesProduct Noise EmissionsChair: Matt Nobile (nobile@us.ibm.com)The scope of the Product Noise EmissionsTechnical Committee is noise emissionfrom products in general, without focusingon a specific product type or family. Thecommittee will primarily be concernedwith the fundamental aspects of acousticalmeasurement technology, methodology,and standardization as they are appliedto products in general. The scope alsoincludes methods for disseminatinginformation on product noise emissionsto consumers and the general public, suchas product noise declarations and labels.Noise control topics may be consideredwhen appropriate, but these are usuallybetter placed under the Passive Controland Active Control Technical Committees.Similarly, the perceptual aspects of productnoise emissions are not included in thisscope since these are addressed in thePerception and Effects of Noise TC. Oneof the goals of this committee is to spinoff sub-committees dealing with particularproduct families that will address noiseemission issues specific to that familyand that will develop measurement anddeclaration test codes specific to theirindustries. The Sub-Committee on ITEis an example of this (even though ithas existed as a separate TC long beforethe establishment of this parent TC).Products include small and large householdappliances, information technologyproducts, home entertainment products,power tools, lawn and garden equipment,air-conditioning products, medicalequipment, test instrumentation, andmany others. Transport vehicles, outdoorconstruction equipment, and typically largeindustrial equipment are not included in thescope of this committee.Sub-Committee onInformation TechnologyEquipment (ITE)Chair: Jeff Schmitt (jeffs@prodigy.net)The scope of the Information TechnologyEquipment Technical Sub-Committeeis noise control engineering relatingto information technology equipment(ITE), with a primary focus on acousticalmeasurement technology, methodology, andstandardization. In addition to organizingspecial sessions at INCE conferences andsoliciting technical papers for NCEJ, theprincipal activities of the Committee areto monitor, elucidate, and continuallyreevaluate the technical underpinningsof the acoustical standards and test codespertinent to the ITE industry. Given that ourmembers are volunteers with limited timeand resources, the activities undertaken bythe committee should meet the followingpractical criteria: (i) can be reasonablyhandled by the resources available; (ii) aredirectly related to the mission of the TC/ITE; (iii) are important to the IT industry asa whole; (iv) are timely, in terms of workbeing done by other committees allied tothe IT industry (such as standards writinggroups); (v) are of strong interest to amajority of the TC members or potentialTC members; (vi) are within the realm ofexpertise of the TC members or potentialTC members; and (vii) are of a nonproprietarynature to allow competing firmsto cooperate freely. The results of TC/ITEactivities should benefit either INCEmembers in general or members of workinggroups developing standards and test codesfor the ITE industry.Prediction and ModelingTechniquesChairs: Bryce Gardner (bryce.gardner@esi-group-na.com)This committee will provide a forum forthe dissemination and clarification ofinformation related to the direct applicationof large scale computer analysis codesor software to noise control and acousticproblems. Analysis methods or codes ofinterest include finite and boundary elementmethods, statistical energy analysis,ray tracing, transfer matrix and othercomputational techniques for addressinginterior and exterior sound propagationand radiation issues including interactionswith vibrating structures and other media.An attempt will be made to establish aclear forum on the applicability of existingor new codes and numerical techniquesto contemporary noise control problemsin industry or society. To facilitate thisimportant task, the committee will organizespecial technical sessions for NOISE-CON and INTER-NOISE meetings,solicit authoritative papers for NoiseControl Engineering Journal, and providea forum for its members in maintainingand developing the science and art ofcomputer modeling. Other activities mayinclude the formulation of benchmark noisecontrol problems for analysis verification,organizing round robin modeling exercises,and liaison with other technical committeesor professional societies.Building AcousticsChairs: Kenric VanWyk (kvanwyk@acousticsbydesign.com) and MandyKachur (mandy@acousticsbydesign.com)The objective of the Building AcousticsTechnical Committee is to advance theunderstanding of acoustical performanceof building components, materials,and systems, with the ultimate goalof improving the acoustical qualityfor buildings of all types. This is doneby organizing technical sessions atINCE conferences, encouraging thepublication of papers on related topics,152 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2007 December

and disseminating relevant information tothe noise control engineering community,American Institute of Architects, AmericanSociety of Heating, Refrigeration, and AirConditioning Engineers, other professionalgroups, and the public. Primary topicsinclude criteria for sound quality inbuildings, acoustical performance ofbuilding materials including standardconstruction materials as well as specialacoustical products, prediction of soundlevels in buildings, sound propagationthrough building structures and soundproduced by HVAC, electrical andplumbing systems.The committee seeks to identify buildingnoise control topics of interest to thebuilding development, design, andowner sectors through two means: 1) theconsulting practice of acoustical consultantson the committee and 2) standards activitiesin the building acoustics areas. Onceidentified, NOISE-CON and INTER-NOISE sessions will be developed thataddress these areas of interest. Personswho are working in these areas and knownby committee members will be invitedto give papers at these sessions. Thesewill be individuals known to committeemembers directly or indirectly throughcontacts with other members. The invitedpapers will form the basis of a sessionto which a general solicitation of paperswill be made. The next, and most critical,step is to encourage presenters to preparemanuscripts for submission to NCEJ forconsideration for publication.acoustical noise pertaining to methods ofmeasurement, evaluation, and control of asrelated to the areas of environmental andoccupational noise.Recent standards activity is highlightedby the adoption of ANSI S12.68 -2007Methods of Estimating Effective A-Weighted Sound Pressure Levels whenHearing Protectors are Worn. Thisstandard specifies three methods, inascending order of complexity of use andpotential accuracy, for the estimation ofthe sound pressure levels that are effectivewhen a hearing protector is worn.There has also been work surroundingseveral active working groups. WorkingGroup 38 is developing a documentconcerning the noise labeling of productsunder co-chairs J. Pope and R. Hellweg.WG 41, under the guidance of co-chairsL. Finegold and B. Brooks, is addressingmodel community noise ordinances. Also,Working Group 44 is proposing newstandards regarding speech privacy inhealthcare facilities. Each working groupmeets on an annual or semi-annual basisand reports back to the S12 Committee.

Though rating and computational methodshave been previously described in the literature, andgovernmental publications and regulations, this isthe first time that an American National Standardspecifies such procedures.This standard specifies three methods, in ascendingorder of complexity of use and potential accuracy,for the estimation of the sound pressure levels thatare effective when a hearing protector is worn. Thesimplest of the methods is similar to the well-knownNRR, but diverges in two key aspects: namely itcan be used with A-weighted sound pressure levelsinstead of requiring the use of C-weighted levels,and instead of specifying a single number at the 98thpercentile, it provides values for the 80th and 20thpercentiles. This standard is accompanied by aninformational spreadsheet programmed to performthe calculations specified in the standard itself.This Standard was developed by AccreditedStandards Committee S12, Noise, under operatingprocedures accredited by the American NationalStandards Institute (ANSI). These procedures assurethat the Standard represents the consensus of opinionamong those with a direct and material interest inthe subject matter. The standard was drafted by aworking group comprising experts from all segmentsof the hearing conservation community.This standard and many other national andinternational noise standards can be obtained fromthe Acoustical Society of America Online Store athttp://asa.aip.org.

Email: asastds@aip.orgNew Standard on Loudness isAvailableThe Acoustical Society of America has announcedthat a new standard, ANSI S3.4-2007, AmericanNational Standard Procedure for the Computation ofLoudness of Steady Sounds, is now available. Thestandard is a revision of ANSI S3.4-2005.This standard specifies a procedure for calculatingthe monaural and binaural loudness of steady sounds154 www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2007 December

as perceived by listeners with normal hearing. Theprocedure is based on the spectra of the sounds.The possible sounds include simple and complextones (both harmonic and inharmonic), bands ofnoise and mixtures of tones and noise. The spectracan be specified exactly, in terms of the frequenciesand levels of individual spectral components, orapproximately, in terms of the levels in 1/3 octavebands covering center frequencies from 50 to 16,000Hz. The standard is applicable to sounds presentedin free field with a frontal incidence, in a diffusefield, or listening via headphones. The procedureis available as a computer program that providesthe loudness level in phons and the correspondingloudness estimate in sones. Examples of theestimates generated by the program for a variety ofinput spectra are presented in Annex A. The softwarefor calculation of loudness according to ANSI S3.4-2007 is described in Annex B. It accompanies thestandard for the convenience of the purchaser.
