Abstract
An overview of studies on impulse noise induced hearing loss is presented. It is maintained that the equal energy hypothesis (EEH) is a procedure that relates noise induced hearing loss to the total acoustic energy of noise exposure and is a useful concept for continuous noise which can be applied to large sample studies. It was found, however, that results from controlled laboratory experiments using impulse noise ran counter to the EEH. Impulse noise produced effects different from relations found between various parameters of continuous noise and the resulting TTS/PTS. Measurement and classification procedures for impulse noise are proposed. The effects of impulse noise on auditory function in terms of variability, TTS recovery patterns, amplitude and duration, critical duration and number of impulses, microstructure of the impulse, temporal pattern of the exposure, and interaction of continuous and impulse noise are discussed.
