• Consider how suprathreshold auditory measures could help detect early-stage noise-induced hearing loss.

CEU Questions

1. _______ is considered a gold standard for detecting noise-induced hearing loss.

   • Conventional audiometry

   • Auditory brainstem response

   • Middle-ear muscle reflex

2. Damage to the __________ is referred to as cochlear synaptopathy.

   • Outer hair cell

   • Inner hair cell ribbon synapse

   • Cochlear duct

3. Auditory nerve fibers with a ___________ spontaneous firing rate with _______ thresholds are more susceptible to noise-induced cochlear synaptopathy.

   • low, high

   • high, low

   • low, low

4. _____ noise is considered more traumatic than ______ noise.

   • Impulse, steady state

   • Steady-state, impulse

   • Unpleasant, pleasant

5. __________ are associated with high noise exposure background (NEB) in the present study.

   • Reduced middle ear muscle reflex (MEMR) thresholds, reduced QuickSIN SNR loss, and reduced auditory brainstem responses (ABR) wave I amplitude

   • Elevated MEMR, elevated QuickSIN SNR loss, and reduced ABR wave I amplitude

   • Elevated MEMR, reduced QuickSIN SNR loss, and increased ABR wave I amplitude

6. Past studies associated noise-induced cochlear synaptopathy with

   • Reduction in auditory brainstem response (ABR) wave I amplitude and a selective loss of auditory nerve fibers (ANFs) with low spontaneous firing (SF) rates.

   • Increased latency in ABR wave I and a loss of ANFs with low SF rates.

   • Reduction in ABR wave III amplitude and a loss of ANFs with high SF rates.

7. What type of noise exposure was controlled for the low-noise exposure group, but not for the high-noise exposure group in the present study?

   • Steady-state noise

   • Transient noise

   • Impulse noise

8. What were the three types of criteria used for identifying audiometric notches in the present study?

   • Phillips's criteria, Niskar's criteria, and Coles's criteria

   • Le Prell's criteria, Niskar's criteria, and Coles's criteria

   • Phillips's criteria, Nondahl's criteria, and Coles's criteria

9. The association between middle-ear muscle reflex and noise-exposure background (NEB) was:

   • Not significant for either the right or the left ear.

   • Statistically significant in the right ear, with individuals with high NEB showing elevated MEMR thresholds.

   • Statistically significant in the right ear, with individuals with low NEB showing elevated MEMR thresholds.

10. The findings of the present study suggest that the most sensitive clinical measure for detecting early-stage noise-induced hearing loss is:

    • Audiometric thresholds

    • Audiometric notches at 3 – 6 kHz

    • Suprathreshold auditory measures
