title: Human cochlear changes in noise induced hearing loss.
abstract: The temporal bone histopathological findings in 14 ears with noise induced hearing loss are presented. The morphological changes consist mainly of hair cell loss, which is more severe in the 9 mm to 13 mm region of the cochlear duct. Within the area of maximum hair cell loss, there is a greater loss of outer hair cells than of inner hair cells. There is a good correlation between the permanent auditory threshold shifts and the spatial location of the sensory lesion according to the anatomical frequency scale.
