Noise induced hearing loss is accompanied by a wide variety of hearing
deficits, including threshold and suprathreshold deficits, which ofte
n prevent effective rehabilitation even when hearing aids are used. A
study of the neural mechanisms responsible for deficits associated wit
h sensorineural loss is based on neurophysiological and anatomical res
earch. In this paper, we intend to review the basic physiological char
acteristics of the peripheral auditory system.
