ACOUSTICS - ESTIMATION OF NOISE-INDUCED HEARING LOSS
出版：International Organization for Standardization
专家解读视频
Provides 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 disability according to various formulae when the hearing threshold levels at commonly measured audiometric frequencies, or combinations of such frequencies, exceed a certain value.
