Abstract
Objective:To explore the relation between distortion products and frequency tuning charateristics in cochlear basilar membrane.Method:Time variances curves of distortion products and frequency tuning curves of basilar membrane response were measured by laser interferometery in situ guinea pig cochlea.Result:Response sensitivity and tuning sharpness of basilar membrane response decreased with distortion product amplitude and become most low and flat when distortion products disappeared.Conclusion:Distortion products in cochlea are related with hearing sensitivity and frequency tuning. They are indicator whether function of cochlear hearing sensitivity enhancing and frequency tuning sharpening is still at work.
