Title Comparative studies of the noise-reducing capability and the wearing comfort of hearing protectors in the workplace
Original title Vergleichende Untersuchungen der Dämmwirkung und der Trageeigenschaften von Gehörschutzmitteln am Arbeitsplatz [in German]
Bibliographic information 1983, Vol.29, No.2, p.93-98. Illus. 41 ref.
Abstract Characteristics of various hearing protectors (cotton wool, plugs, helmets, earmuffs) were tested during the manufacture of screws (continuous noise of 94dB) and in the forging shop of a machinery plant (impact noise of 95-109dB). No differences were found between the noise-reducing powers of the protectors by comparing the temporary reduction in the hearing threshold of the workers, but significant differences were found in their degree of comfort. For long-term use, the best protection is provided by plastic foam plugs (with prolonged resilience). Principles are given for the organisation of a hearing conservation programme.
