Level Dependence of the Latency of Cochlear Transients
An important consequence of the fact that cochlear mechanics are nonlinear is what the latency of the auditory nerve response to transient sounds is level dependent. Specifically, the latency of the neural response decreases as the sound level increases. The cochlear component of the latency of human auditory brainstem responses (ABR) t0 tone-burst sumuh has been shown to consistently decrease by about 38% for every 20 dB mcrease m the level of the stimulus (Neely et al., 1988). Moreover, this consistent latency decrease with level holds over a wide range of tone-burst frequencies and intensities.
