1.  Candidacy for frequency lowering amplification:
  1. is based on the audiogram alone
  2. may include those who cannot achieve adequate high frequency amplification from gain and WDRC amplification
  3. does not include adult patients
  4. does not include children
2.  Hearing speech above 4000 Hz:
  1. gives children access to the plural and possessive marker /s/
  2. gives children access to fricative sounds
  3. is important for developing speech/language
  4. all of the above
3.  Which umbrella term for the technology discussed in this article encompasses the technology available across manufacturers?
  1. frequency transposition
  2. frequency compression
  3. frequency lowering
  4. frequency translation
4.  Which of the following patients would be least likely to be a candidate for frequency lowering technology?
  1. Young child with precipitously sloping hearing loss
  2. Adult with mild, flat hearing loss
  3. Adult with steeply sloping hearing loss
  4. Adult with moderate loss, with poor aided audibility over 4000 Hz
5.  Default settings for frequency lowering:
  1. are best fit settings for adults, for most successful outcomes
  2. are best fit settings for children, for most successful outcomes
  3. are best fit settings for children and adults, for most successful outcomes
  4. are only a starting point for children and adults, and require verification for individual patients
6.  The first step in fitting frequency lowering technology is to:
  1. verify the hearing aid fitting is set to a validated target such as DSL or NAL
  2. use the manufacturer’s default first fit setting, and then set frequency lowering to maximum
  3. conduct the TEN test to see if there are any dead regions to consider
  4. set your probe microphone equipment to use the standard LTASS
7.  What test signals are recommended for verification of frequency lowering technology?
  1. chirps
  2. tone bursts
  3. filtered speech
  4. warp consonants
8.  For a clinician who is experienced with hearing aid programming and probe microphone verification, the author suggests that verifying and finetuning frequency lowering technology, should take approximately:
  1. 60 minutes
  2. 30 minutes
  3. 4 - 5 minutes
  4. no additional fitting time
9.  When using frequency lowering technology, to keep sounds like /s/ and /sh/ from overlapping, the author recommends:
  1. the weakest possible setting that gives audibility for the 6000-9000 Hz region of speech, but maximizes the separation between these two sounds
  2. the strongest possible setting that gives audibility for 6000 – 9000 Hz and maximizes the separation between these two sounds
  3. turn off frequency lowering above 4000 Hz
  4. none of the above
10.  An outcome measure that may help determine if a patient is benefitting from frequency lowering technology is:
  1. UWO Plurals Test
  2. Measure aided detection thresholds in dB HL with calibrated Ling-6 sounds
  3. Both A and B
  4. None of the above
