Gain-Delay Decoupling in Human Stimulus Frequency Otoacoustic Emissions Reveals Constraints on Cochlear Nonlinear Amplification.
PURPOSE The nonlinear cochlear amplifier, driven by outer hair cells, underlies the remarkable sensitivity and frequency selectivity of the mammalian auditory system. Stimulus frequency otoacoustic emissions (SFOAEs) provide a noninvasive window into these active cochlear processes, yet the relationship between emissio...
