Bibliographic information Jan.-Mar. 1983, Vol.7, p.28-38. Illus. 4 ref.
Abstract Studies of 5 sets of earmuffs are presented. A small microphone was connected to the ear inside the muff. The noise source was a ball mill in a cement works, and each earmuff was worn by at least 2 different operators. Results varied considerably. Performance of the earmuff depended considerably on the spectral composition of the noise. Only one model satisfied the authors' criterion of attenuation of more than 19dB(A).
