where does sound get converted into neural impulses ​
Transduction (physiology)
In the auditory system , sound vibrations ( mechanical energy ) are transduced into electrical energy by hair cells in the inner ear . Sound vibrations from an object cause vibrations in air molecules , which in turn , vibrate your ear drum . The movement of the eardrum causes the bones of your middle ear ( the ossicles ) to vibrate . These vibrations then pass in to the cochlea , the organ of hearing . Within the cochlea , the hair cells on the sensory epithelium of the organ of Corti bend and cause movement of the basilar membrane . The membrane undulates in different sized waves according to the frequency of the sound . Hair cells are then able to convert this movement ( mechanical energy ) into electrical signals ( graded receptor potentials ) which travel along auditory nerves to hearing centres in the brain .
