... Transmission of sounds into inner ear is done by outer and middle ear. Outer ear: auricle (ear pinna) and external auditory canal. Optimally audible sounds come frontally under the angle of about 15 measured away the ear axis. Auditory canal is a resonator. It amplifies the frequencies 2-6 kHz with ...
