Abstract : Three studies were conducted to determine the reliability, under various exposure conditions, of temporary threshold shift (TTS) produced by impulse noise. The subjects, who were representative of the Army population, were tested at frequencies throughout the range of human hearing. Individual subjects' TTSs were not consistent enough to permit any meaningful generalizations. However, group-mean TTS was a reliable measure of impulse-noise effects for subjects with both normal and subnormal hearing, and throughout the range of audible frequencies. Basing interpretations on these types of data should insure that results from various tests will be comparable. (Author)
