1.  Which patients can benefit from a bilateral Baha solution?
  1. Patients with bilateral mixed or conductive hearing loss
  2. Patients with less than or equal to 10 dB difference in bone conduction thresholds on average (.5, ,1, 2 & 3 kHz) between ears
  3. Patients with less than or equal to 15 dB difference at individual bone conduction frequencies
  4. All of the above
2.  Compared to bilateral fittings for hearing aids, bilateral fittings for Baha systems are:
  1. Much rarer
  2. Much more common
  3. About the same
  4. Slightly less common
3.  Clinical benefits of bilateral Baha system fittings include:
  1. Improved ability to localize sounds
  2. Improved hearing in background noise
  3. Improved audibility
  4. All of the above
4.  A recent consensus meeting on bilateral Baha systems
  1. Recommended only fitting bilateral Baha systems for appropriate pediatric patients
  2. Strongly recommended bilateral fittings for appropriate pediatric patients and recommended consideration of bilateral fittings for appropriate adult patients
  3. Recommended only fitting bilateral Baha systems for appropriate adult patients
  4. Did not recommend fitting bilateral Baha systems in any patients
5.  Active Bilateral Directionality is:
  1. Useful only for unilateral Baha system users
  2. An algorithm that has been available in previous generation Baha sound processors
  3. Only available on the Baha 5 sound processor but not the Baha 5 Power sound processor
  4. An algorithm to improve hearing in background noise by taking advantage of ear-to-ear exchange between ears
6.  The following sound processors can be bilaterally linked and programmed in Baha Fitting Software 5.4:
  1. Two Baha 5 sound processors
  2. Two Baha 5 Power sound processors
  3. A Baha 5 and a Baha 5 Power sound processor
  4. All of the above
7.  In addition to Active Bilateral Directionality, ___________ can be used to improve bilateral Baha recipients hearing in background noise.
  1. True Wireless accessories such as the Mini Microphone 2+
  2. Turning the gain for the sound processor up into the red area
  3. Performing a Baha take-home trial with SoundArc
  4. Turning one sound processor off
8.  Asymmetrical directionality means that:
  1. Directionality in both ears is always the same
  2. One ear can be in a directional mode while the other is in an omnidirectional mode
  3. The microphones are directional to the side
  4. None of the above
9.  Fitting of bilateral Baha systems is especially important in children with bilateral mixed or conductive hearing loss because:
  1. One processor may break down
  2. Unilateral fittings for Baha are not successful in children
  3. Bilateral fittings allow children to use all auditory cues to develop binaural hearing
  4. Baha surgery is only available to children aged 5 or older
10.  The following types of Baha systems can be fit bilaterally:
  1. Non-surgical Baha options, such as Softband or SoundArc
  2. Baha Connect (ie, percutaneous Baha solutions)
  3. Baha Attract (ie, transcutaneous Baha solutions)
  4. All of the above
