This process, known as auditory processing, involves basilar tuning and tonotypical mapping. High frequency sounds activate hair cells at the cochlea's base, while low frequency sounds stimulate cells at the apex. These signals travel via the auditory nerve to the primary auditory cortex in the brain, allowing us to perceive different sounds.

Students see how basilar membrane motion bends hair cells, generating nerve impulses, and how different frequencies peak at specific locations for auditory processing.
