Listening Effort and Social Engagement

Please note: exam questions are subject to change.

1. Listening Effort: Is under control of the listener Increases in the presence of hearing loss Will vary from person to person All of the above
2. Listening Effort is: The same as listening stress and fatigue Is the same across all environments for a given listener Will be expended if the person is achieving a payoff Is determined solely by the environment
3. Listening effort can be measured: By asking the listener Via the use of pupilometry Via the use of EEG All of the above
4. The pupils dilate: As a direct function of overall sound level As the listener expends listening effort When the user has quit trying Right before speech starts
5. Open Sound Navigator: Eliminates all noises in the environment Uses only directionality to achieve its effect Increases the effort required to understand speech None of the above
6. Open Sound Navigator: Uses directional and noise reduction effects to provide a cleaner signal to the user Provides only one speech source to the user Eliminates all sounds except those in a narrow listening beam None of the above
7. In the study discussed, Open Sound Navigator allowed for: An approximately 5 dB improved in speech understanding in noise Lower overall listening effort across a range of environments A reduction in approximately 5 dB in the environments in which the listener is willing to expend effort All of the above
8. In the study discussed: Only sounds from in front of the listener were presented Speech was presented in an environment with noise coming from multiple directions Subjects were told how hard to listen Subjects rated how hard they felt they had to work
9. Socialization in older adults: Has been linked to long term cognitive health Naturally declines, but at even a faster rate in the presence of hearing loss May decline even without the person being consciously aware All of the above
10. The Hearing Fitness Tracker: Monitors pupilometry Is provided data from the patient's Opn hearing devices Is used to warn patients away from complex listening environments Monitors EEG
