IHS Auditory Assessment 4

Question 1

Which of the following best describes the Stenger test and its primary application?

Accepted Answer

Identifies functional (non-organic) unilateral hearing loss

Answer

The Stenger test exploits the Stenger effect — when the same tone is presented to both ears simultaneously, only the louder one is perceived — to unmask feigned unilateral hearing loss.

Question 2

In pure-tone audiometry, the recommended test frequency sequence per ASHA guidelines begins with:

Accepted Answer

1000 Hz

Answer

ASHA recommends starting pure-tone testing at 1000 Hz because it is in the most reliable portion of the audiogram and allows for a retest at 1000 Hz to check response reliability.

Question 3

A conductive hearing loss is confirmed on the audiogram when:

Accepted Answer

Air conduction thresholds are elevated but bone conduction thresholds are within normal limits

Answer

A conductive hearing loss is indicated by elevated air conduction thresholds with normal bone conduction thresholds, creating an air-bone gap of 10 dB or more.

Question 4

Which acoustic reflex pattern is most consistent with a unilateral acoustic neuroma on the right side?

Accepted Answer

Absent ipsilateral and contralateral reflexes with right probe and absent contralateral with left probe

Answer

An acoustic neuroma on the right (CN VIII) disrupts the afferent arc, causing absent reflexes when the right ear is stimulated (both ipsi and contra right-probe) and absent contralateral reflex when the left ear is stimulated.

Question 5

Otoacoustic emissions (OAEs) are generated by which cochlear structure?

Accepted Answer

Outer hair cells

Answer

OAEs are produced by the electromotile activity of outer hair cells (OHCs), which amplify basilar membrane motion and generate sounds that travel back through the middle ear.
