The Impact of Oticon Opn on Patient Performance

---

1.  BrainHearing is: a specific technology and Oticon hearing aids an approach to developing solutions for patients with hearing loss a technique to assess cognitive processing none of the above

2.  OpenSound Navigator: improved speech understanding in complex environments without creating a narrow listening field is driven by a unique combination of directionality and noise removal provides updated solutions for the listener up to 100 times per second all of the above

3.  Listening effort can be assessed via: electrophysiological methods patient questionnaires dual-task approaches all of the above

4.  Pupil size: has been shown to increase when more effort is applied to a cognitive task has been shown to decrease when more effort is applied to a cognitive task flickers when effort is applied to a task freezes when effort is applied to a task

5.  Open Sound Navigator has been shown to: Lead to more pupil dilation when activated then when deactivated Lead to less pupil dilation when activated then when deactivated Have no effect on pupil size Have the greatest effect on pupil size in quieter environments

6.  OpenSound Navigator has been shown to: disrupt word recall have no effect on word recall allow for improved word recall in complex environments require more effort when activated to complete the word recall task

7.  When the task is to identify speech coming from only directly in front in a complex environment: Opn performs on par with beamforming Opn performs more poorly than traditional directionality Opn performs on par with traditional directionality Opn provides no assistance in this environment

8.  When the task is to identify speech coming randomly from multiple speakers in the front half of the listening field: Opn performs on par with beamforming Opn performs on par with traditional directionality Opn outperforms both beamforming and traditional directionality none of the above

9.  Compared to OTC style instruments, the effect of Opn on patient performance: will be more significant as the listening situation becomes more complex cannot be measured will be similar will show poor performance

10.  Patients who have tinnitus and who wear Opn: cannot use the Sound Support feature cannot be tested using pupilometry because of the presence of tinnitus show reduced listening effort when Open Sound Navigator is activated show increased listening effort when Open Sound Navigator is activated
