Why does sensorineural hearing loss often exhibit frequency-dependent sensitivity?

💡 Explanation

Sensorineural hearing loss displays frequency-dependent sensitivity because the cochlea's hair cells are arranged tonotopically; high-frequency sounds are processed at the base, and low-frequency sounds at the apex. Therefore, damage to specific regions affects particular frequency ranges, rather than an even loss, because the location of the damaged cells dictates the affected frequencies.
