Psych Ch. 6 Section 3 (Audition)

Front 1

Hertz

Back 1

the primary measure of the frequency of vibration of sound waves; cycles per second

Front 2

Cochlea

Back 2

A snail shaped chamber set in bone in the inner-ear, where the auditory receptor cells are found and transduction takes place

Front 3

Ossicles

Back 3

The three bones of the middle ear (the hammer, anvil, and stirrup) that transmit acoustical vibrations from the eardrum to the membrane behind the oval window of the cochlea.

Front 4

Oval window

Back 4

An opening in the bone surrounding the cochlea. The stirrup presses against window of the cochlea.

Front 5

Basilar membrane

Back 5

One of two membranes that divide the cochlea of the inner ear into three compartments. The auditory receptor cells based in the membrane respond to its movements.

Front 6

Round window

Back 6

an opening in the bone surrounding the cochlea. Movements of the membrane behind

Front 7

Auditory hair cells

Back 7

The sensory neuron of the auditory system; located on the basilar membrane

Front 8

Cilia

Back 8

A hair like appendage of a cell; involved in transducing the mechanical energy of sound waves. found on the sensory receptors in the auditory and vestibular systems.

Front 9

Tectorial membrane

Back 9

a membrane located above the basilar membrane; serves as a shelf against the cilia of the auditory hair cells move.

Front 10

Harmonics

Back 10

a components of a complex tone; one of a series of tones whose frequencies are multiples of the fundamental frequency.

Hint 10

In music theory, also known as an overtone.

Front 11

Fundamental frequency

Back 11

The lowest, and usually the most intense, frequency of a complex sound; most often perceived as sounds most basic pitch

Front 12

Timbre

Back 12

a perceptual dimension of sound determined by its complexity; representable by a mathematical analysis of the sound wave
