Abstract
The noise causes a masking effect that disturbs verbal communications. The noise limits the perception of acoustic signals of security with an increased probability of accidents at work. The noise increases the mental fatigue and decreases the efficiency of the work performance. The level of exposure to noise by hearing protectors can be estimated by the methods specified by two standards BS EN ISO 4869-2 and BS EN 458. In this paper we compare the methods using different hearing protectors.File in questo prodotto:
