True

False

. The ear is most sensitive to frequencies between about 100 Hz and 300 Hz.

True

False

. The fluids of the inner ear are similar in composition to plasma.

True

False

. The perceived loudness of a sound depends on the amplitude of the vibrations affecting the ear.

True

False

. The muscles of the middle ear act to increase the sensitivity of the ear to low intensity sounds.

True

False

. The middle ear acts to maximize the transfer of sound energy from the air to the fluids of the inner ear.

True

False

. Which of the following statements regarding the process of hearing are correct?

The movement of the basilar membrane activates the outer hair cells which are responsible for sound transduction.

The inner hair cells are responsible for sound transduction.

The constituent frequencies of a sound are mapped along the basilar membrane.

High frequencies stimulate the hair cells of the basilar membrane nearest the apex of the cochlea.

. Which of the following statements regarding hearing deficits are true?

A similar degree of hearing loss for air conduction and bone conduction indicates sensorineural hearing loss.

A similar degree of hearing loss for air conduction and bone conduction indicates conductive hearing loss.

unilateral damage to the auditory cortex does not result in any obvious hearing deficit.

Extensive damage to the auditory cortex of the dominant hemisphere may cause difficulties in the recognition of speech
