  3. Pitch?
    A tone’s experienced highness or lowness; depends on frequency
  4. Middle Ear?
    Chamber b/w the eardrum and cochlea containing 3 tiny bones -hammer, anvil, stirrup-that concentrates the vibrations of the eardrum on the cochlea’s oval window
  5. Cochlea?
    Coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
  6. Inner ear?
    The innermost part of the ear, containing the cochlea, semicircular canals and vestibular sacs
  7. Place Theory?
    The people hear different pitches because different sounds waves trigger activity at different places, determines a pitch by recognizing specific place that is generating neural signal
  8. Frequency Theory?
    When the brain reads pitch by monitoring the frequency of neural impulses traveling up the auditory nerve.
  9. Conductive hearing loss?
    Problems with the mechanical system that conducts sound waves to the cochlea
  10. Sensorineural hearing loss?
    Damage to the cochlea’s hair cell receptors or their associated nerves
  11. Cochlear implant?
    Converting sounds into electrical signals ands stimulating the auditory nerve through electrodes threaded into the cochlea
  12. Kinesthesis?
    Sense of the position and movement of body parts
  13. Vestibular sense?
    Monitor’s the head and body’s position and movement
