WebSome numerical solutions of this model show basilar membrane displacement amplitudes of about 1 angstrom for sound pressures at the eardrum of 0 dB SPL (20 µPa). The rate of energy flow out of the basilar membrane into the cochlear fluid due to the cochlear amplifier is often more than 40 dB greater than the rate of energy flow into the ...
WebMay 23, 2011 · The cochlear amplifier is believed to reside at an area immediately basal to the BF location –, (blue bar in Fig. 1C). As waves propagate through this region the cochlear amplifier generates energy … WebHearing sensitivity in mammals is enhanced by more than 40 dB (that is, 100-fold) by mechanical amplification thought to be generated by one class of cochlear sensory cells, the outer hair cells. In addition to the mechano-electrical transduction required for auditory sensation, mammalian outer hair cells also perform electromechanical transduction, …
