Hearing Loss Audiological Testing and Diagnosis Test 1

Question 1

What does an audiogram graphically display?

Accepted Answer

A person's hearing thresholds across different frequencies

Answer

An audiogram is a graph that plots a person's hearing thresholds (the softest sounds they can detect) at various test frequencies, typically from 250 Hz to 8000 Hz.

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 hearing threshold is defined as the lowest intensity level at which a patient can correctly detect a pure-tone stimulus at least 50% of the time.

Question 3

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

Accepted Answer

Decibels Hearing Level (dB HL)

Answer

Audiograms use decibels Hearing Level (dB HL), a scale referenced to the average thresholds of young adults with normal hearing, making 0 dB HL the normative baseline.

Question 4

What does tympanometry primarily assess?

Accepted Answer

Mobility of the tympanic membrane and middle ear pressure

Answer

Tympanometry measures how the eardrum (tympanic membrane) moves in response to changes in air pressure, providing information about middle ear pressure, fluid, and ossicular chain integrity.

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

The SRT is the lowest hearing level (dB HL) at which a patient can correctly repeat spondee (two-syllable, equal-stress) words 50% of the time, confirming pure-tone average results.
