IHS Auditory Assessment 2

Question 1

Which masking noise type is most appropriate when masking for pure-tone air conduction testing?

Accepted Answer

Narrow-band noise

Answer

Narrow-band noise centered at the test frequency is the preferred masking stimulus for pure-tone air conduction testing because it is most effective at masking the specific test tone.

Question 2

A patient's speech reception threshold (SRT) should agree within how many decibels of the pure-tone average (PTA)?

Accepted Answer

10 dB

Answer

The SRT should agree within ±10 dB of the pure-tone average for the results to be considered valid and consistent.

Question 3

When performing tympanometry, a Type B tympanogram with a large ear canal volume most likely indicates:

Accepted Answer

Tympanic membrane perforation

Answer

A Type B tympanogram with abnormally large equivalent ear canal volume (ECV) is characteristic of a tympanic membrane perforation or patent pressure equalization tube.

Question 4

The occlusion effect is most significant at which frequencies?

Accepted Answer

Low frequencies (250–500 Hz)

Answer

The occlusion effect predominantly enhances bone-conduction thresholds at low frequencies (250–500 Hz) by increasing the sound pressure in the occluded ear canal.

Question 5

Which test is used to assess the integrity of the efferent auditory pathway?

Accepted Answer

Contralateral suppression of OAEs

Answer

Contralateral suppression of otoacoustic emissions (OAEs) tests the medial olivocochlear bundle, which is part of the efferent auditory pathway.
