Audition

3. The dimension of frequency determined by the wavelength of sound.
8. Characteristics of sound from a zither and a guitar allows the ear to distinguish between the two. We use words like sharp, reedy, brassy, and bright.
11. More common hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerve, also called nerve deafness.
12. Amount of energy in a wave, determined by the amplitude, relates to the perceived loudness.
14. Innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs → responsible for balance/coordination
15. Makes the distinction among musical instruments possible
16. Also called the ear canal, the tube-shaped passage that carries sound waves from the pinna to the tympanic membrane (eardrum). The canal amplifies certain frequencies and protects the eardrum by producing cerumen (earwax).
17. Pinna, ear canal, and eardrum - Collects sounds

1. Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea.
2. suggests that sound frequencies stimulate the basilar membrane (strip of tissue within the cochlea that contains the cilia/stereocilia) at specific places resulting in perceived pitch.
4. composed of compression and rarefaction of air molecules
5. The distance from the peak of one wave to the peak of the next.
6. states that the rate of nerve impulses traveling up the auditory nerve* matches the frequency of a tone, thus enabling us to sense its pitch
7. Conversion of sound waves into neural impulses in the hair cells of the inner ear.
9. Because we have two ears, sounds that reach one ear faster than the other ear cause us
10. Chamber between eardrum three tiny bones that concentrate the vibrations of the eardrum (tympanic membrane) on the cochlea’s oval window, amplifying pressure 20x.
13. Coiled, bony, fluid-filled tube in the inner ear that transforms sound vibrations to auditory signals.
