Fit or Fiction: Why and How Every Audiologist Should Incorporate Hearing Protector Fit Testing in Their Practice

Please note: exam questions are subject to change.

1. Which of the following statements about hearing protector fit testing is true? It requires special equipment not available in a typical audiology clinic. It can be done only by audiologists who have special training and certification in fit testing. It is only required when the Noise Reduction Rating of a hearing protector is unknown. It can help prevent noise-induced hearing loss.
2. Which of the following is NOT true about the Personal Attenuation Rating (PAR) compared to the Noise Reduction Rating (NRR)? The PAR is based on a field test, whereas the NRR is derived from a laboratory test. The PAR is an individual measure, whereas the NRR is a population estimate. The PAR estimates protected exposure levels, whereas the NRR estimates noise reduction. The PAR is based on user fit, whereas the NRR is based on experimenter fit.
3. What is an appropriate target protected noise exposure level that avoids both overprotection and underprotection? 60-75 dBA 70-85 dBA 80-95 dBA 90-105 dBA
4. What clinical audiology procedure can be used to conduct a subjective hearing protector fit test? Sound field threshold audiometry Speech-in-noise testing Acoustic reflex thresholds ABR
5. Which clinical audiology procedure can be used to conduct an objective hearing protector fit test? Sound field threshold audiometry Uncomfortable loudness level Tympanometry Real-ear probe microphone measures
