The science behind hearing loss The cochlea in our inner ear contains 15,000 tiny, hair-like structures called “stereocilia”, or hair cells. There are two types: auditory and vestibular, responsible for hearing and balance respectively. Auditory hair cells function by bending in response to sound, and their movements are transmitted as electrical signals to the brain, which interprets them as sound. When these hair cells are damaged or killed, it can cause permanent hearing loss—
