Sound
Sound waves, characterized by frequency and amplitude, are perceived uniquely by different organisms.
The Vestibular System
Gravity, acceleration, and deceleration are detected by evaluating the inertia on receptive cells in the vestibular system.
Reception of Sound
The outer, middle, and inner structures of the ear collect sound energy, converting it to audible sound.
Transduction of Sound
When sound waves reach the ear, the ear transduces this mechanical stimulus (pressure) into a nerve impulse (electrical signal) that the brain perceives as sound.
