Cochlear coiling makes inner nerve damage cause low-frequency hearing loss
Evidence
The coiling of the cochlea means that the neurons responsible for communication data relating to low-frequency components in incoming sound are toward the center of the auditory nerve, with those responsible for the communication of higher frequency being wrapped around them (see Figure 2.3(a)). Any damage to the outside (inside) of the auditory nerve will therefore result in high- (low-) frequency hearing loss respectively. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 567
