Abstract
Basilar membrane (BM) motion was measured at a site 3.5 mm from the basal end of the chinchilla cochlea using the Mössbauer technique. In preparations with little surgical damage, mechanical responses were as sharply tuned as auditory nerve fibers with the same characteristic frequency (CF, about 8.4 kHz). High-frequency plateaus were observed in both isovelocity tuning curves and phase-frequency curves. Input-output functions at frequencies around CF were strongly nonlinear. Another type of nonlinearlty, two-tone suppression, was also demonstrated in several cochleas, with suppression effects as large as 28 dB.
