CCC Audiology and Hearing Sciences 1

Question 1

Which type of hearing loss results from damage to the outer or middle ear, preventing adequate sound transmission to the cochlea?

Accepted Answer

Conductive hearing loss

Answer

Conductive hearing loss occurs when a mechanical problem in the outer or middle ear reduces the transmission of sound energy to the inner ear.

Question 2

On an audiogram, the air-bone gap indicates which finding?

Accepted Answer

Conductive component to the hearing loss

Answer

An air-bone gap, where bone conduction thresholds are better than air conduction thresholds, indicates a conductive component to the hearing loss.

Question 3

Otoacoustic emissions (OAEs) measure the function of which structure?

Accepted Answer

Outer hair cells of the cochlea

Answer

OAEs are sounds generated by the outer hair cells of the cochlea and are measured to assess cochlear (outer hair cell) integrity.

Question 4

Which audiological test assesses the integrity of the auditory brainstem pathway by measuring electrical responses to sound?

Accepted Answer

Auditory brainstem response (ABR)

Answer

The ABR records electrical responses from the auditory nerve and brainstem to click or tone-burst stimuli, assessing neural pathway integrity.

Question 5

Presbycusis is defined as age-related hearing loss and typically presents as which audiometric pattern?

Accepted Answer

High-frequency sensorineural hearing loss

Answer

Presbycusis typically causes a bilateral, symmetric, high-frequency sensorineural hearing loss due to cochlear hair cell degeneration with age.
