Sound is transmitted to the fluid of the inner ear through vibrations of the tympanic membrane, malleus, incus and stapes. Transduction, the change from mechanical energy to neural impulses, takes place in the hair cells, specifically through potassium channels at the tips of the stereocilia.
How does sound transduction occur?
Vibrating objects, such as vocal cords, create sound waves or pressure waves in the air. When these pressure waves reach the ear, the ear transduces this mechanical stimulus (pressure wave) into a nerve impulse (electrical signal) that the brain perceives as sound.
What part of the ear is responsible for the transduction of sound?
The part of the inner ear that transforms sound waves into electrical impulses is the cochlea. The cochlea is a snail-shaped structure that coils around a bony axis called the modiolus. The base of the cochlea is contiguous with the middle ear - through the vestibule - and its tip goes deep into the temporal bone.
