Answer 13

Small amplitude

Question 14

Characteristics of sound from a zither or a guitar allows the ear to distinguish between the two is an example of what

Answer 14

Timbre, quality

Question 15

What collects sound

Answer 15

Pinna or outer ear

Question 16

What is defined as the middle of the ear

Answer 16

The chamber between eardrum and cochlea containing three tiny bones (hammer, anvil, stirrup) that concentrates the vibrations of the eardrum on the cochlea window

Question 17

What are the three tiny bones in the middle of the ear

Answer 17

The hammer, anvil, and stirrup

Question 18

What is considered the inner ear

Answer 18

Cochlea, semicircular canals, and vestibular sacs

Question 19

In order, how does sound travel through the ear

Answer 19

Auditory canal, tympanic membrane, hammer, anvil, stirrup, oval window, cochlea, auditory nerve

Question 20

What is the coiled, bony, fluid-filled tube in the inner ear

Answer 20

Cochlea

Question 21

What transforms sound vibration into auditory signals

Answer 21

Cochlea

Question 22

What is the basilar membrane

Answer 22

Holds auditory receptors

Question 23

Where are hair cells located

Answer 23

In cochlea

Question 24

What are hair cells responsible for

Answer 24

Changing sound vibrations into neural impulses

Question 25

What does the auditory nerve do

Answer 25

Carries sound information from the ears to the temporal lobe

Question 26

True or False: hearing takes place in the brain, not the ears

Answer 26

True

Question 27

What is place theory

Answer 27

Place theory holds the perception of pitch corresponds to the vibration of different portions, or locations, along the basilar membrane (like a harp)

Question 28

What is frequency theory

Answer 28

Frequency theory holds the perception of pitch corresponds to the rate, or frequency, at which the entire basilar membrane vibrates (like a drum)

Question 29

What are the two factors of localization of sound

Answer 29

Intensity and time differences

Question 30

Contrast conduction hearing loss and sensorineural hearing loss

Answer 30

Conduction refers to the mechanical system and sensorineural refers to the cochlea cells or auditory nerves

Question 31

Implants that are electronic devices that enable the brain to hear sounds

Answer 31

Cochlear implants
