Please note, this is a rather simplified description of frequency coding based on a concept called "rate coding." At higher frequencies (i.e., > ~1 kHz), multiple auditory nerve fibers must simultaneously contribute to the coding of frequency, because a single auditory nerve fiber cannot do it alone ("teamwork makes the dream work!"). The more commonly described mechanism underlying frequency coding is the tonotopically based "place theory".
