1.  Which statement best describes a key distinction between traditional hearing aid processing and DNN-based processing?
  1. Traditional processing amplifies only low-frequency sounds, whereas DNN processing amplifies only high-frequency sounds.
  2. DNN-based processing can use learned representations of acoustic environments to inform how incoming sound is processed.
  3. DNN-based processing eliminates the need for directional microphones.
  4. DNN-based processing primarily increases overall hearing aid output.
2.  Why can competing-talker environments present a different challenge from traditional speech-in-noise conditions?
  1. Competing talkers are always louder than the target talker.
  2. Speech from competing talkers contains no useful acoustic information.
  3. Competing talkers can share many of the acoustic characteristics of the target speech, making separation and selective attention more challenging.
  4. Competing talkers occur only in reverberant environments.
3.  Which technology helps ReSound Sensa™ recognize the acoustic environment?
  1. Auracast
  2. AcoustIQ
  3. M&RIE
  4. Smart Hearing Alliance
4.  A patient reports that they can understand speech reasonably well in quiet but become overwhelmed when several people are talking at once. Which clinical approach is most appropriate when considering advanced DNN-based processing?
  1. Evaluate only the patient's pure-tone thresholds.
  2. Assume that improved audibility alone will resolve the difficulty.
  3. Consider the patient's performance and experience in complex listening environments and evaluate whether advanced processing may provide additional support.
  4. Avoid directional processing because it can never benefit multi-talker environments, especially in the high frequencies
5.  What does the DNN in ReSound Sensa™ help the hearing aid do?
  1. Recognize and process sound using deep neural network technology
  2. Increase battery life by reducing processing
  3. Automatically adjust the physical fit of the hearing aid
  4. Replace the need for microphones
