Cochlear mechanics: Nonlinear behavior in two‐tone responses as reflected in cochlear‐nerve‐fiber responses and in ear‐canal sound pressure
DO Kim, CE Molnar, JW Matthews - … Journal of the Acoustical Society of …, 1980 - pubs.aip.org
Over the last five years, we have studied spatial distributions of cochlear responses to single‐
and two‐tone stimuli by recording sequentially from as many as 418 cochlear nerve fibers in
each cat and obtaining plots of amplitude and phase of response components at primary
and distortion frequencies. We have observed:(1) that such responses to two‐tone stimuli of
sound pressure levels (SPL) as low as 34 dB re 20 μN/m2 rms show noticeable deviations
from linear behavior;(2) that two major forms of nonlinear behavior in responses to two‐tone …
