It is not the intentionof this paper to recommend one treatment programover another, but rather offer insight to the role soundplays in these different treatment programs, and howwireless streaming capabilities offers a unique flexibilitynever seen before.

Vol 123 No 1311; ISSN 1175 8716Page 112-125. URL: http://www.nzma.org.nz/journal/123-1311/4040/Tinnitus is the perception of sound in the absence ofan acoustic stimulus. It can vary greatly in its perceptualcharacteristics from person to person. Althoughthe exact mechanism of tinnitus causation is unknown,the origin of tinnitus activity is believed to liesomewhere within the auditory pathways (Henry et.al, 2008). Tinnitus is a concern for many people, andaffects approximately 10-15% of the overall population,with approximately 20% of that population sufferingfrom clinically treatable tinnitus (A. Davis & Refaie,2000; Jastreboff & Hazell, 1998). In addition, approximately80% of all tinnitus sufferers also have hearingloss. This shows the importance of having an effectivecombination unit, such as <strong>ReSound</strong> Alera TS TM , whichcan address both the hearing loss and tinnitus concernsof these individuals.There are different approaches of treating tinnitus, suchas medical management (in cases where the tinnituscan be addressed medically), educational counselingand sound therapy, each having a unique approach totinnitus management. Up until now, little research hasbeen published in regards to the effectiveness of hearinginstruments, tinnitus sound generators (TSGs) orcombination units for tinnitus management. This maybe partly to due to the fact that past ear-level technologyfor tinnitus management has been far from ideal,and this lack of flexibility has not addressed the uniqueneeds of each individual. For the most part, peoplestruggling with tinnitus have had to make due with eitherwhite noise generators, or preset music that maynot always be preferred by the user. Within the differenttinnitus management programs available, eachhas some distinct differences on how they incorporatesound into their management protocols, and pasttechnologies have not offered the flexibility to meet allthese requirements.Tinnitus management programsSound TherapyIn almost all tinnitus management programs, soundtherapy of some kind plays a significant role. Althoughcounseling alone can be used without sound therapy,it is often times not as effective as using a combinedapproach. Counseling-only type treatments aren’t intendedto change, or reduce the acoustic perceptionsof the tinnitus, but rather change the reactions to tinnitus,and the negative effects it may bring. This can bevery beneficial in regards to improving one’s reactionsto their tinnitus, but may not be enough for some tinnitussufferers.Sound therapy’s main intention is to divert one’s attentionaway from the tinnitus. By introducing sound intoone’s environment, we are able to minimize the contrastbetween the tinnitus and the background environment(Figure 1). For example, in a quiet room tinnitusis easily detected since there is a large discrepancybetween the loudness of the tinnitus and quietness ofthe environment. By enriching the environment withsound, we increase the loudness of the backgroundenvironment, therefore making the tinnitus less prominentand noticeable. Sound therapy can have immediateeffects, helping to reduce tinnitus audibility (e.g.masking/partial masking) which can also potentiallyresult in taming the underlying tinnitus. Sound stimulationmay also reverse or modify the abnormal corticalreorganization thought to be responsible for tinnitus(Searchfield et. al, 2010).LoudnessDecreased contrast betweentinnitus and noiseibility to accommodate any tinnitus management plan.In this paper, we will review some of the more wellestablishedtinnitus management programs, such asIncreased noise levelSound Therapy, Tinnitus Retraining Therapy (TRT) andProgressive Tinnitus Management (PTM), and howsound enrichment and wireless streaming using theM200586-GB 11.04 Rev.B<strong>ReSound</strong> Unite TM Mini Microphone can play a beneficialrole in achieving the goals of these tinnitus managementprograms.FrequencyFigure 1: Increasing the background noise level reduces the contrastbetween the tinnitus and the background sound level.

Open-fit hearing instrumentshave been beneficial to a number of tinnitus sufferers,since the open ear canal allows for more naturalsound to enter, and therefore provides a form of ‘natural’sound therapy (Del Bo, et. al 2008). Hearing streetnoise, or people talking can enrich one’s environmentwith sound, therefore making the tinnitus harder to detect.Although many people benefit from using hearinginstruments alone for tinnitus management, there area number of people where amplification alone is notFigure 2: The <strong>ReSound</strong> Unite TM Mini MicrophoneSounds used for sound therapy can vary in their temporal,spectral and emotion-evoking characteristics(Searchfield et. al, 2010).Searchfield et al showed that a rain sound signal waspreferred over a white noise sound signal when itcame to masking the tinnitus. Some argue that moredynamic sounds (i.e. rain) are better at helping to masktinnitus, compared to less dynamic sounds (i.e. whitenoise) (Henry et. al, 2004). In addition, music was theleast favored when it came to masking the tinnitus dueto the cognitive stimulation and the attention it brings.cal model of tinnitus and was created by Dr. Pawell J.Jastreboff in the mid 1980s.TRT reflects a general rule that we do not react to theabsolute but to the relative strength of a stimulus comparedwith the background (Jastreboff & Hazell, 2008).For example, the fan of a ventilation system in a veryquiet room will sound much louder than if that samefan is on in a crowded room with people talking andmusic on (e.g. a cocktail party), even though the intensityof the ventilation fan has not changed. The sameholds true with tinnitus. If we increase the intensity ofthe background environment, and thus stimulate morebackground neuronal activity, then the tinnitus signalwill not be perceived to be as strong, even though thetinnitus signal itself has not changed.TRT also discusses in-depth the role of the limbicsystem and the autonomic nervous system (ANS) inregards to tinnitus. The limbic system is greatly con-NegativereactionFigure 3: The vicious cycle of tinnitusIncreased awarenessof tinnitusInitialappearanceof tinnitusWithin TRT, sound therapy can provide a weakeningof the tinnitus signal by decreasing the contrast betweenthe tinnitus signal and the background neuronalactivity. This can facilitate perceptual changes tothe tinnitus. However, there are strict rules as to whatsounds should be used to increase the backgroundenvironment.Many of these requirements can be addressed byusing the broadband white noise TSG feature within<strong>ReSound</strong> Alera TS TM . For those users who do not enjoythe sound of white noise, wireless streaming allowsyou to use any type of continuous, stable sound(i.e. pink, red, blue, violet, steady nature-like sounds,etc.), offering flexibility to address the unique needsand preferences of each tinnitus sufferer. It also providesnumerous options to maximize the requirementsof TRT and increase the chances of successful outcomes.Progressive Tinnitus Management (PTM)Similar to TRT, Progressive Tinnitus Management(PTM) uses sound, as well as counseling, as a vitalrole in helping to achieve the goals of the managementplan. PTM is a patient-centered approach to tinnitusmanagement, which uses specific evaluation procedures,emphasizes the appropriate use of sound,encompassed within a five-step hierarchical plan.
