Auditory Transduction The Inner Ear

Auditory Transduction The Inner Ear. 5.3.13. Outer Ear. Pinna collects the sound and directs it to ear canal Because of the length of the ear canal, it is capable of amplifying sounds with frequencies in range 2000-3000 Hz. Ear canal acts as a resonator for this fundamental frequency.
