Title Acoustics - Determination of occupational noise exposure estimation of noise-induced hearing impairment
Original title Acoustique - Détermination de l'exposition au bruit en milieu professionnel et estimation du dommage auditif induit par le bruit [in French]
Bibliographic information International Organization for Standardization, P.O. Box 56, 1211 Genève 22, Switzerland, 1990. 17p. Illus.
Abstract This international standard specifies a method for calculating the expected noise-induced permanent threshold shift in the hearing threshold levels of adult populations due to various levels and durations of noise exposure; it provides the basis for calculating hearing handicap according to various formulae when the hearing threshold levels at commonly measured audiometric frequencies, or combinations of such frequencies, exceed a certain value.
