Abstract
The sound attenuation of TDH-39 earphones with MX-41/AR cushions has been measured in two different configurations: 1) earphones attached to the usual audiometric headband, and 2) earphones mounted in a noise-excluding headset, ME-70 from Madsen Electronics. The measurement method was in accordance with ISO 4869-1981 for hearing protectors, using 1/3-octave noise bands in a diffuse field.
For almost all frequencies, the attenuation results (config. 1) are lower than the guidance values given in the audiometric test method standard, ISO/DIS 8253. The noise-excluding headset (config. 2) provides a 7-10 dB better attenuation.
