ch 5 pt 2

Audition

Hearing the sense of sound, perception

Soundwave

Pattern of changes in air pressure during a period of time which produces the percept of a sound

Hertz

Humans can text on waves with frequencies from about 20 Hz to about 20,000 Hz

eardrum

Then membrane that vibrates in response to auditory stimuli and transmit sounds waves to middle ear

Hammer anvil and stirrup

Tiny bones in the middle ear vibrate in response to vibrations of the eardrum

Oval window

The membrane covered opening that separates the middle ear from the inner ear

cochlea

Snail shaped organ in the inner ear that contains sensory receptors for hearing

Basilar Membrane

Membrane inside the cochlea stimulates hair cells

Organ of Corti

Gelatinous structure in the cochlea containing the hair cells that serve us auditory receptors

Hair cells

Hair cells are the sensory receptors of the auditory system and the vestibular system in the ears

Sound localization

The brain integrates a different sensory information is coming from each year

vestibular sense

Perception of balance, determined by receptors in the inner ear

Temporal coding

A mechanism for encoding, low frequency, auditory stimuli in which the firing rate of cochlear hair cells match the frequency of the soundwave

Place coding

A mechanism for encoding, high frequency, auditory stimuli in which the frequency of the sound wave was encoded by the no location of the hair cells along the basilar membrane
