The former portion of the auditory system is the first point at which sound wave modification begins. It collects sound waves in the series of “hills and valleys” and channels them into the external auditory canal.

The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified.
