HAC Types of Hearing Loss & Assessment 3

Question 1

Which condition is characterized by episodes of vertigo, fluctuating low-frequency hearing loss, tinnitus, and aural fullness?

Accepted Answer

Meniere's disease

Answer

Meniere's disease is caused by endolymphatic hydrops and presents with the classic tetrad of episodic vertigo, fluctuating sensorineural hearing loss, tinnitus, and ear fullness.

Question 2

When masking is required during bone conduction testing, the masking noise is delivered to:

Accepted Answer

The non-test ear via insert or supra-aural earphone

Answer

During bone conduction testing, masking noise is placed in the non-test ear to prevent it from responding to the signal.

Question 3

A downward-sloping audiogram configuration most commonly indicates:

Accepted Answer

High-frequency sensorineural damage

Answer

A ski-slope or downward-sloping audiogram, with worse thresholds at high frequencies, reflects damage to the high-frequency region of the cochlea.

Question 4

Which test measures the acoustic reflex, indicating the integrity of the middle ear, cochlea, and brainstem pathway?

Accepted Answer

Acoustic immittance testing

Answer

Acoustic immittance testing (tympanometry + reflex testing) evaluates middle ear function and the stapedius reflex arc involving CN VII and VIII.

Question 5

An audiogram showing hearing thresholds within 0–25 dB HL across all frequencies for an adult is classified as:

Accepted Answer

Normal hearing

Answer

Per standard audiometric classification, thresholds of 0–25 dB HL in adults are considered within the normal range.
