  1. Middle Ear
    the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea's oval window
  2. Cochlea
    a coiled, bony fluid filled tube in the inner ear through which sound waves trigger nerve impulses
  3. Inner Ear
    the innermost part of the ear, containing the cochlea, semicircular canals and vestibular sacs
  4. Place Theory
    in hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated
  5. Frequency Theory
    in hearing, the theory that the rate of nerve impulses travelling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch
  6. Conduction Hearing Loss
    hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
  7. Sensorineural Hearing Loss
    Hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves; also called nerve deafness
  8. Cochlear Implant
