1.  According to Singh & Launer (2016), what is the relationship between a significant other attending an appointment and hearing aid adoption rate?
  1. There is no relationship
  2. All people who bring a significant other are MORE likely to adopt a hearing aid.
  3. All people who bring a significant other are LESS likely to adopt a hearing aid.
  4. People with mild hearing loss who bring a significant other are much more likely to adopt a hearing aid.
2.  What potential explanation(s) did Singh & Launer (2016) offer for their finding?
  1. People who bring significant others have inherently different personalities than those who attend appointments alone
  2. People who bring significant others are under more social pressure than those who attend appointments alone.
  3. Significant others can help resolve purchase uncertainty.
  4. All of the above
3.  Regarding Wind Noise Reduction, how many major manufacturers have demonstrated processing with the potential to significantly increase speech recognition?
  1. None
  2. One
  3. Two
  4. Six
4.  Kornhonen et al. (2017) demonstrated the potential for significantly reduced annoyance and improved speech recognition for speech presented from:
  1. One angle
  2. Any angle from the front hemifield
  3. Any angle from the side hemifield
  4. From above
5.  According to Moore and Sak (2016):
  1. Clinical measurement of temporal fine structure can provide a clear indication of the preferred compression time constant.
  2. Although not 100% accurate, choosing slow time constants may be the "safest" choice when considering sound quality for music.
  3. Always use fast time constants when sound quality is the primary concern.
  4. Compression time constants have no effect on preference.
6.  According to Neher et al. (2016), the majority of preferences for directional and DNR technologies could:
  1. Be explained by executive control
  2. Be explained by PTA
  3. Be explained by other cognitive factors
  4. Not be explained by the factors tested
7.  According to Neher et al. (2016), preference for noise reduction technologies (both DNR and directional) is affected by:
  1. Configuration and number of talkers
  2. The specific type of noise reduction
  3. Individual patient difference in expression of cognitive factors
  4. All of the above
8.  What was the primary finding from Joseph et al. (2016)?
  1. Current hearing aid user guides are written at grade levels ABOVE recommended reading levels for health information
  2. Current hearing aid user guides are written at grade levels BELOW recommended reading levels for health information
  3. The grade level of hearing aid user guides depends on the source - guides written by manufacturers are easier to read
  4. The grade level of hearing aid user guides depends on the source - guides written by manufacturers are harder to read
9.  Caposecco et al. (2016) based their modified hearing aid user guides on which field?
  1. Otorhinolaryngology
  2. Health literacy
  3. Graphic design
  4. English literature
10.  Which of the following hearing aid tasks were most likely to be improved by the modified hearing aid user guide evaluated by Caposecco et al. (2016)?
  1. Taking the hearing aid out of the ear
  2. Turning up the volume
  3. Inserting the hearing aid into the ear, and cleaning the hearing aid
  4. Changing the battery and turning the hearing aid on/off
