- 3. theory, theory regarding how the inner ear registers the frequency of sound, stating that the perception of a sound’s frequency depends on how often the auditory nerve fires
- 5. ear, consists of the pinna and the external auditory canal
- 7. membrane, lines the inner wall of the cochlea and runs its entire length
- 10. sounds, numerous frequencies of sound blend together
- 12. membrane, separates the outer ear from the middle ear
- 15. outer- visible part of the ear; collects sounds and channels them into the interior of the ear
- 17. ear, part of the ear that includes the oval window, cochlea, and basilar membrane and whose function is to convert sound waves into neural impulses and send them to the brain
- 18. the perception of the sound wave’s amplitude
- 19. timing and ____ help us to localize a sound
Down
- 1. the number of cycles that pass through a point in a given interval
- 2. nerve, the nerve structure that receives information about sounds front the hair cells of the inner ear and carries these neural impulses to the brain’s auditory areas
- 4. principle, modification of frequency theory stating that a cluster of nerve cells can fire neural impulses in rapid succession producing a volley of impulses
- 6. theory, theory regarding how the inner ear registers the frequency of sound, stating that each frequency produces vibrations at a particular spot on the basilar membrane
- 8. the amount of pressure a sound produces relative to a standard
- 9. tone saturation of a sound
- 11. window, transmits sound waves to the cochlea
- 13. tubular, fluid-filled structure that is coiled up like a snail shell
- 14. cells, ear’s sensory receptors
- 16. ear, the part of the ear that channels sound through the eardrum, hammer, anvil, and stirrup to the inner ear
- 20. shadow, caused by the listener’s head, which forms a barrier that reduces the sound’s intensity
