ReSound LiNX 3D: The Details and Benefits of Binaural Directionality III

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

1.  Adaptive directional hearing instruments will
  1. Fix the directional polar characteristics to match a hypercardioid pattern.
  2. Change the distance between the microphones to change the polar pattern.
  3. Adapt the polar characteristics to provide the least gain for azimuths with the most noise.
  4. Adapt the listener into different listening situations
2.  ReSound BandSplit Directionality provides what benefits(s)?
  1. Improved low-frequency sound quality with directional benefit.
  2. Improved speech understanding in directional frequency areas.
  3. Adjustable crossover frequency for ideal balance between directional benefit and sound quality.
  4. All of the above
3.  Asymmetric directionality is set with
  1. Both ears omnidirectional
  2. Both ears directional
  3. One ear directional and one ear omnidirectional
  4. Both A & B
4.  Binaural Directionality
  1. uses the input to both hearing aids to determine the best directional setting
  2. changes the directional setting between four different directional modes depending on the environment
  3. provides both directional benefit and 360 degrees awareness when appropriate
  4. All of the above
5.  When patients wearing hearing aids want to hear a person sitting on their right in a background noise, the hearing aids show be in the following directional settings for best understanding
  1. Both ears being directional due to the background noise
  2. Right hearing aid in omnidirectional mode and the left in either omni or directional.
  3. Right hearing aid in directional and the left in directional
  4. None of the above
6.  Spatial cues are provided by the following:
  1. Interaural Timing Differences (ITD)
  2. Interaural Level Differences (ILD)
  3. Visual Cues
  4. All of the above
7.  To restore interaural level difference between two hearing aids
  1. The pinna and concha directional cues must be restored due to microphone placement
  2. The compression between the two devices must be synchronized
  3. The low-frequency phase differences must be must be restored
  4. Both A & B
8.  For an asymmetric directionality mode when the right ear is omni-directional and the left ear is directional, Binaural Directionality III will improve audibility of which direction?
  1. Left front
  2. Left rear
  3. Right front
  4. Right rear
9.  Binaural Directionality provides significantly better understanding compared to bilateral narrow-beam directionality
  1. When the noise is all around and the speech is from the side
  2. When the noise is all around and the speech is from behind
  3. When the noise is all around and speech is from the front
  4. A & B
10.  Natural Directionality II
  1. Provides improved signal-to-noise ratio for sounds in front of the listener
  2. Provides awareness and audibility of sounds around the listener
  3. Provides the listener an increased noise reduction setting
  4. Both A & B
