After that the auditory nerve still fires in the same phase as the stimulus, but individual fibers skip one or more cycles and fire only in response to one in so many peaks. Overall, the 16,000 fibers do reproduce the stimulus perfectly though. But then, acoustic pitch is primarily a place-code and not so much a rate code. | |

But to the best of my knowledge (used to teach audio engineering) the hair cells in the cochlea do not discharge at such rate. Rather, the highest rate of discharge is around 12-14 kHz. Perceived frequencies higher than that are the sum component of intermodulation caused by non-linearities. | |
