27 The correction factors in dB, which are necessary to obtain the corresponding data for 38M2A panels (of 38M1A) and 30SA (of 35kA) are shown in the table below. Type of coating Correction factor [dB] calcium sulfate 30S -1 Chipboard 38M2 0 Natural stone (S) and reconstructed (R), Ceramic tile (T Finally, the correction factors in dB are shown below for obtaining panel data with a lower cover in steel instead of aluminum. Below are some examples of how to get the data for each particular group. Type of coating Correction factor [dB] Steel (F) 0 Ex.1: Panel 38M1 + tile on a structure with stringers 1. In diagram 1 the data in relation to the panel 38M1 with stringers obtained are M = 34 dB; 2. From Table 1 is extracted correction factor for the coating of tiles (T), which is - 1dB. The horizontal aerial noise reduction is, therefore, (Dnfw) 34-1 = 33dB Ex.2: Panel 30SF + vinyl on a structure with stringers P and with acoustic insulation sheet stuck. 1. In diagram 1 the data in relation to the panel 35SA with stringers P obtained are P = 36 dB; 2. From Table 1 is extracted correction factor for the vinyl (V), which is + 1 dB; 3. From Table 2 extracts the correction factor for the panel 30S starting at 35S, which is-1dB; 4. From Table 3 extracts the correction factor in the lower cover in steel, which is 0 dB. Therefore, the reduction of aerial sound horizontal is (D nfw ) 36 + 1-1+ 0 = 36dB. NOTE: It should be noted that the process of in-situ test was carried out in a modular access floor installed in compliance with current regulations in place with construction features and standard techniques. In particular, we note the following: • The slab was cleaned completely and then it was applied an anti-dust product; • The slab with RAP honeycomb shape of pre-compressed air was perfectly smoothed, with a total thickness of 20 + 5 cm; • A simple dividing wall was used for testing with a thickness of 100 mm (plasterboard 12.5 mm, stone wool + 40 + plasterboard12.5 mm); • A perimeter adhesive seal was placed on the edge of the tile 25x25mm; • The supports were stuck in compliance with appropriate regulations for the slab; • For the test it was used a sound insulation sheet with a thickness of 5 mm; • For the test it was used an acoustic partition under the floor sound with the same features of the partition wall. -1
vertical transmission of noise In the presented data are the steps taken in a real building in accordance with current regulations (EN ISO 140-8), to evaluate the eff ect of reducing the modular access fl oor in relation to the transmission of noise surface of the panel (or how a person in a . fl oor of a building perceives the noise present in an upper fl oor). In this case, measures are taken fi rst without the modular access fl oor in order to determine the features of the building itself. The same measures are taken then with the modular access fl oor already installed. The measurements are recorded for the description of the diff erences of the eff ect of the added element (modular access fl oor). We present the test results of impact noise reduction panel expressed by the parameter ALW measured in dB. The higher the value the greater the reduction in relation to the object to be tested and therefore the greater the reduction in the transmission of noise when walking on the fl oor that is transmitted to the lower fl oor. The following data were collected from the panels: The fi rst diagram shows ALw values obtained in diff erent structural confi gurations, and panels 38M1A and 35SA. The observed conditions diff ered depending on whether there were stringers or not, if there was a noise insulation sheet placed between the support and the tile and if it was stuck or not (required to stick the pieces have been installed without stringers).
