Lesson Summary. According to the frequency theory of hearing, the frequency of the auditory nerve's impulses corresponds to the frequency of a tone, which allows us to detect its pitch. Sounds come into the ear as acoustical signals and are later transformed into nerve impulses by the cochlea. The auditory nerve transfers these nerve impulses to the brain. Frequency theory of hearing can only account for sounds up to 5,000 hertz. The place theory of hearing accounts for sounds at or above 5,000 hertz.
