Hearing Loss Audiological Testing and Diagnosis Test

Question 1

What does an audiogram graphically display?

Accepted Answer

A person's hearing thresholds across different frequencies

Answer

The shape and structure of the inner ear

Answer

The electrical activity of the auditory nerve

Answer

The pressure levels inside the middle ear

Question 2

During pure-tone audiometry, what does the patient's 'hearing threshold' represent?

Accepted Answer

The softest sound the patient can detect at least 50% of the time

Answer

The loudest sound the patient can tolerate

Answer

The average loudness of normal conversation

Answer

The frequency at which the patient hears best

Question 3

What unit of measurement is used to express hearing thresholds on an audiogram?

Accepted Answer

Decibels Hearing Level (dB HL)

Answer

Hertz (Hz)

Answer

Pascals (Pa)

Answer

Decibels Sound Pressure Level (dB SPL)

Question 4

What does tympanometry primarily assess?

Accepted Answer

Mobility of the tympanic membrane and middle ear pressure

Answer

Hair cell function in the cochlea

Answer

Auditory nerve conduction speed

Answer

Speech recognition ability in noise

Question 5

What is the primary purpose of the Speech Recognition Threshold (SRT) test?

Accepted Answer

To measure the lowest intensity at which a patient can correctly identify 50% of spondee words

Answer

To determine how well a patient understands speech in background noise

Answer

To assess auditory processing in the brainstem

Answer

To evaluate the patient's ability to discriminate between phonemes

Question 6

Otoacoustic Emissions (OAE) testing is used primarily to assess which structure?

Accepted Answer

The outer hair cells of the cochlea

Answer

The tympanic membrane

Answer

The auditory cortex

Answer

The Eustachian tube

Question 7

Which audiological test measures the brain's electrical response to sound and does not require a behavioral response from the patient?

Accepted Answer

Auditory Brainstem Response (ABR)

Answer

Pure-tone audiometry

Answer

Speech discrimination testing

Answer

Visual Reinforcement Audiometry (VRA)
