Answer 0

Frequency

Question 1

The sense or act of hearing

Answer 1

Audition

Question 2

A tone’s experienced highness or lowness; depends on frequency.

Answer 2

Pitch

Question 3

The chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea’s oval window.

Answer 3

Middle ear

Question 4

A coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses.

Answer 4

Cochlea

Question 5

The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs

Answer 5

Inner ear

Question 6

In hearing, the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated.

Answer 6

Place theory

Question 7

In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, Thus enabling us to sense its pitch.

Answer 7

Frequency theory

Question 8

Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea.

Answer 8

Conduction hearing loss

Question 9

Hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerves; also called nerve deafness.

Answer 9

Sensorineural hearing loss

Question 10

A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea.

Answer 10

Cochlear implant
