| Abstract |
A method was developed for testing the sound-attenuating properties of hearing protectors during wearing in the workplace. The values obtained were compared with the results of laboratory measurements according to standard ISO 4869. The performance of ear plugs in the field was clearly inferior to that predicted by type testing in the laboratory according to standard DIN 32 760. The difference between field and laboratory values was much less for earmuff-type protectors, but used equipment of this type afforded less protection than new. |
