Studies of Aural Nonlinearity and the Mechanisms of Auditory Fatigue

Abstract

A study relating individual differences in certain auditory and physiological parameters to individual susceptibility to auditory threshold shifts has been started. This report describes progress from 1 October 1978 to 13 July 1979. The initial parameter under study was auditory amplitude nonlinearity. However, in the process of the investigation, examination of the data suggested that tobacco smoking habits might be a confounding variable and this was investigated separately. The preliminary data suggest that smoking does predispose the individual to higher fatigued threshold shifts. Data at 1KHz suggest a relationship between amplitude non-linearity and threshold shifts. The results at 500 Hz and 2KHz are less clear. Reasons for this are discussed. Additional data must be acquired and analyzed before the relation between nonlinearity and impulse and continuous noise-induced TTS can be fully evaluated. (Author)
