Prior human studies suggested that sensory-cell loss is rarely the cause; correspondingly, animal work has implicated the stria vascularis, the cellular “battery” driving the amplification of sound by hair cell “motors.” …

WebTo create hearing loss models, chinchillas can be exposed to continuous noise at >115 dB SPL ( Pourbakht and Yamasoba, 2003 ), or 110 dB SPL for five consecutive days ( Dunn et al., 1991 ).
