| Abstract |
Objective tests of 12 models of ear-muff-type hearing protectors, done under laboratory conditions, resulted in the determination of the total insertion loss and the spectral-response characteristics of the insertion loss. The method for ear-muff testing with respect to impulsive noise, based on a method recommended by ISO/DIS 6290 in the case of stationary pink noise, may be used for comparative purposes and for quality control. Subjective tests carried out in an industrial plant revealed that the use of hearing protectors diminished the temporary threshold shift TTS2, which means that hearing protectors can protect against the harmful effects of impulsive noise. |
