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


1.  What are the different kinds of bone conduction devices?
  1. Passive and Active
  2. Passive and Reactionary
  3. Standard and Reactionary
  4. Active and Standard
2.  Which of the below parts compose the bone conduction portion of the BONEBRIDGE device?
  1. Receiver coil
  2. BC-FMT
  3. Demodulator
  4. Abutment
3.  Which part of the BCI (bone conduction implant) transfers the sound energy to the bone?
  1. Demodulator
  2. Floating mass transducer
  3. Screws
  4. Magnet
4.  What is the correct candidacy range of bone conduction thresholds for the BONEBRIDGE device?
  1. -10 to 45 dB
  2. 0 to 60 dB
  3. -10 to 25 dB
  4. 0 to 25 dB
5.  What are the advantages of the BONEBRIDGE system when compared to conventional bone conduction solutions?
  1. Pressure is needed to transmit sound across the skin
  2. No open wound that requires constant maintenance
  3. Easy to attach to its abutment
  4. Can be attached to a headband for pediatric populations
6.  What is the BONEBRIDGE candidacy range (in air conduction thresholds) for patients with single sided deafness?
  1. -10 to 20 dB in contralateral ear
  2. 0 to 60 dB in contralateral ear
  3. -10 to 20 dB in ipsilateral ear
  4. 0 to 60 dB in ipsilateral ear
7.  How many microphone ports does the SAMBA audio processor have?
  1. One
  2. Two
  3. Three
  4. Zero
8.  What features within the SAMBA audio processor were designed to improve speech understanding?
  1. Automatic volume control
  2. Feedback is added to signal
  3. Adaptive directional microphone
  4. Microphones are focused forward
9.  What results did the APHAB (Quality of Life) questionnaire show?
  1. Ease of communication and hearing in background noise improved
  2. Reverberation and hearing in background noise got worse
  3. Ease of communication and reverberation scores got worse
  4. Background noise scores were worse after than before
10.  What happened to residual hearing after BONEBRIDGE surgery according to the study presented?
  1. All residual hearing was lost
  2. Some residual hearing was lost (between 10 to 30 dB )
  3. Residual hearing remained unchanged
  4. Residual hearing improved
