Cochlear Implants and Single Sided Deafness: An Easy Approach to Audiological Assessment

View Course Details Please note: exam questions are subject to change.

1.  When using the plug and muff method of isolating the hearing ear, it’s important to
  1. Have the patient close their eyes
  2. Ask the patient which ear they are hearing the sound in
  3. Insert the earplug deeply and use a circumaural earmuff
  4. Deliver masking noise through the speaker facing the naturally hearing ear
2.  A binaural listening skill that usually develops early in the post-activation period is:
  1. Squelch effect
  2. Spatial release from masking
  3. Localization
  4. Improved speech and language development
3.  A reasonable substitute for localization testing if you do not have a speaker surround is
  1. Having the patient demonstrate by pointing to who is talking
  2. Using a validated subjective questionnaire that assesses spatial hearing such as the SSQ
  3. Clapping behind the patient to see which direction they turn
  4. Observing the patient in the waiting room
4.  If your patient is primarily interested in being able to hear someone sitting at a table on their impaired side, the most relevant measure of performance could be
  1. Test to quantify the squelch effect
  2. Localization testing
  3. Subjective questionnaires
  4. Test to quantify the head shadow effect
5.  A method for reducing testing time for binaural listening tests is to:
  1. Give half lists
  2. Ask the patient about their daily listening habits
  3. Establish a signal-to-noise ratio with one binaural listening test, and then use that SNR for subsequent binaural listening tests that day
  4. Use direct connection to the audio processor
