A Brief History of Auditory Models
... The outer ear is the visible portion of the ear. It includes the pinna (also called auricle), the ear canal and the eardrum. The pinna collects the sounds and directs them down into the ear canal. Its shape also help us to extract directional information from sounds. The ear canal is a tube about 2. ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
