Laboratory methods of assessing hearing loss

Abstract

Methods for assessing hearing loss in human and in animals are reviewed with special reference to the use of brainstem auditory evoked potentials (BSEP). The technique of recording and digital filtering of BSEP is described and compared with the results obtained by use of traditional analog filtering. The use of electrophysiological methods in assessing threshold shifts in studies of the effect of noise exposure on hearing in experimental animals is described for examples of results obtained in rats.
