Pediatric Hearing Aid Verification: Innovative Trends

Please note: exam questions are subject to change.

1. Which of the following is a limitation of aided sound field testing using pure tones? Pure tone stimuli at threshold levels are processed differently than speech at moderate levels by the hearing aid Time consuming Cannot be reliably completed on infants Provides limited information about frequency response and output of hearing aid All of the above
2. At what age can children effectively switch their own directional microphones 3 years 5 years 7 years Data on children is limited
3. Which of the following should be taken into account when selecting and fitting hearing aid technologies for children? Children use overhearing to learn speech and language Adult algorithms and gain predictions are not appropriate for use with children Children require higher (more favorable) signal-to-noise ratios than adults with the same hearing loss Children require a wider frequency bandwidth than adults to understand speech All of the above
4. Which of the following statements is NOT true in regards to using Wide Dynamic Range Compression (WDRC) technology with children? WDRC has been shown to improve audibility WDRC enhances speech recognition when compared to linear gain WDRC should never be used with children with more severe hearing losses WDRC ensures listening comfort over a broad range of inputs
5. When ABR threshold results are reported as eHL, this means that: A correction to account for the differences in thresholds between pure tone and brief tone has already been applied to the results A correction to account for the differences in thresholds between pure tone and brief tone needs to be applied if the data will be used to fit a hearing aid Insert earphones were used as the transducer for the evaluation The ABR results are equivalent to thresholds in HL
6. Which of the following limitations of open fit hearing aids should be considered when determining the appropriateness of an open fit device for a child? Lack of FM compatibility Limited gain to address potential progressive hearing losses Inability to provide low frequency gain, if needed Durability All of the above
7. A recent study of speech recognition with directional microphones for school-aged children by Todd Ricketts, Jason Galster and Anne Marie Tharpe concluded that: Directional microphones were beneficial for school-age children across a variety of simulated classroom environments Directional microphones resulted in poorer speech recognition performance across a variety of simulated classroom environments The benefits of directional microphones for school-age children are most evident when the speaker is in front of the student Children should not use directional microphones in classroom environments
8. Verification of single-microphone noise reduction for children who use hearing aids should: Be completed with the directional microphones in an adaptive directional mode Measure that gain is not significantly reduced when noise is present Use a pure tone stimuli in sound field Ensure that noise reduction is off if the hearing aid is being used by a child
9. The primary goal of fitting hearing aids on children with hearing loss is: To provide audibility for speech and prevent loudness discomfort using objective methods Loudness normalization To reduce amplification when cochlear dead regions are present Promote safety by hearing environmental sounds
10. In an expanded view of evidence-based practice, which of the following is NOT an acceptable source of evidence for clinicians to use when making decisions for their patients? Manufacturer marketing and testimonials Peer reviewed research Clinical verification data The perspectives of an informed patient or family
