IHS - International Hearing Society Audiometric Testing Procedures Questions and Answers

Question 1

During pure-tone air conduction audiometry, what is the standard procedure for finding the threshold of hearing after a patient responds to a tone?

Accepted Answer

Decrease the intensity by 10 dB and present the tone again.

Answer

Increase the intensity by 5 dB and present the tone again.

Answer

Present the tone at the same level to confirm the response.

Answer

Move to the next frequency immediately.

Question 2

A client's unmasked air conduction threshold in the right ear at 2000 Hz is 50 dB HL. The bone conduction threshold in the left ear (non-test ear) at the same frequency is 10 dB HL. Using supra-aural headphones with an interaural attenuation of 40 dB, is masking required for the right ear, and why?

Accepted Answer

Yes, because the difference between the air-conduction threshold in the test ear and the bone-conduction threshold in the non-test ear is greater than the interaural attenuation.

Answer

No, because the air conduction threshold is not high enough to require masking.

Answer

No, because the bone conduction in the non-test ear is within normal limits.

Answer

Yes, because masking is always required when testing at 2000 Hz.

Question 3

Which of the following best describes the primary purpose of bone conduction audiometry?

Accepted Answer

To assess the sensitivity of the sensorineural system by bypassing the outer and middle ear.

Answer

To determine the softest sound a person can hear through headphones.

Answer

To measure the function of the middle ear system exclusively.

Answer

To evaluate the effectiveness of hearing aids.

Question 4

A patient is unable to repeat spondee words to establish a Speech Recognition Threshold (SRT). Which test would be the most appropriate alternative to obtain information about their threshold for speech?

Accepted Answer

Speech Detection Threshold (SDT) / Speech Awareness Threshold (SAT)

Answer

Word Recognition Score (WRS)

Answer

Most Comfortable Loudness (MCL)

Answer

Uncomfortable Loudness Level (UCL)

Question 5

According to ASHA guidelines, what is the recommended starting frequency for pure-tone threshold testing?

Accepted Answer

1000 Hz

Answer

250 Hz

Answer

500 Hz

Answer

4000 Hz

Question 6

During audiometric testing, you establish an air-bone gap of 20 dB in the right ear. What does this finding most likely indicate?

Accepted Answer

A conductive or mixed hearing loss in the right ear.

Answer

Normal hearing in the right ear.

Answer

A purely sensorineural hearing loss in the right ear.

Answer

A problem with the auditory nerve on the right side.
