Title Hearing protectors: A review of recent observations
Bibliographic information July 1983, Vol.25, No.7, p.523-526. 30 ref.
Abstract The views of experts speaking at a symposium in Toronto (Canada) in 1980 are reviewed: Methods of quantifying the performance characteristics of hearing protectors, of which the real-ear attenuation at threshold (REAT) is the most widely used; hearing protector performance limits; speech communication problems. In the authors' own laboratory studies, average attenuation of muffs and plugs was less than that expected from manufacturer specifications and than their theoretical potential. Causes were breaking of the seal between head and muff and poor condition of equipment due to age and misuse. Active devices, which electronically modify sound levels under the protector, previously described for military operations, are discussed.
