The Auditory System: Anatomy, Function, and Localization

This lecture covers the anatomy and function of the auditory system, including diffraction by the head and body, the role of the external ear in sound localization, the middle and inner ear mechanisms, and the electro-chemical transmission at hair cells in the cochlea. It explains how diffraction effects and HRTF characterize sound localization, the impedance matching in the middle ear, and the transformation of sound into nervous stimuli in the inner ear. The lecture also discusses the functions of the cochlea, the organ of Corti, and the basilar membrane in processing sound signals.
