The pinna collects sound waves and directs them to the eardrum through the ear canal. When sound waves hit the eardrum it vibrates. The vibrations are transmitted to the ossicles and amplified. The vibration of the stape causes the membrane at the oval window to vibrate. The vibrations of the oval window are transmitted to the perilymph on the sensory nerve fibres. The impulses are transmitted to the brain for interpretation.
