Auditory

Question 1

3 types of noise

Answer 1

pitch
A perceptual dimension of sound; corresponds to the fundamental frequency.


loudness
A perceptual dimension of sound; corresponds to intensity.


timbre
A perceptual dimension of sound; corresponds to complexity.

Question 2

place code

Answer 2

The system by which information about the different frequencies is coded by different locations on the basilar membrane. Changes in pitch cause different hair cell/spiral ganglion cells to be activated.

Question 3

rate code

Answer 3

The system by which information about different frequencies is coded by the rate of firing of neurons in the auditory system (use for frequencies up to 1KHz
Volley firing (neurons fire in alternating waves) can permit rate coding to up to 4KHz

Question 4

cilliim attached by, at?

Answer 4

tip link, insertional plaque

Question 5

tonotopic representation

Answer 5

A topographically organized mapping of different frequencies of sound that are represented in a particular region of the brain.

Question 6

fundamental frequency

Answer 6

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


Question 7

overtone

Answer 7

The frequency of complex tones that occurs at multiples of the fundamental frequency.


Question 8

phase difference

Answer 8

The difference in arrival times of sound waves at each of the ear drums.


Question 9

amusia

Answer 9

Loss or impairment of musical abilities, produced by hereditary factors or brain damage.

Question 10

vesticular system made up of

Answer 10

-semicircular canals
The three ring-like structures of the vestibular apparatus that detect changes in rotation/acceleration of the head 


-vestibular sac
One of a set of two receptor organs in each inner ear that detect changes in the tilt/position of the head.


-Saccule, utricle
The vestibular sacs, containing otoconia
