Auditory
Hearing occurs when sound waves are converted into electrical energy, which stimulates the nerves of the inner ear. Eventually the sound travels along nerve pathways to the brain. Sound waves can travel to the inner ear through the ear canal, eardrum, and bones of the middle ear (air conduction), or through the bones around and behind the ear (bone conduction). |
