Dynamic Soundscape Processing: Research Supporting Patient Benefit

Please note: exam questions are subject to change.

1. Siemens/Signia has been the industry leader in developing the following automatic features that attempt to follow the listener’s intent: Directional technology that automatically switches between omnidirectional and directional processing based on the listening condition. e2e wireless technology—the first wireless system that allowed synchronous steering of both hearing instruments in a bilateral fitting. Development of automatic adaptive polar patterns allowing the null of the pattern to align with a single noise source, or to track a moving noise source. All of the above
2. A component of the new Soundscape Processing is: Motion Sensors Smoke Alarm Heart Monitor Blood Pressure Monitor
3. An expected advantage of the new soundscape processing is: Less wind noise Better awareness of acoustic environment Increased dynamic range All of the above
4. In laboratory research, when the participant was stationary, ratings for speech understanding for a talker from the side/back were: Significantly better with the new processing “on” Better with processing on, but not significantly so The same for processing “on” or “off.” Better with the new processing “off”
5. In laboratory research, when the motion sensor was “active,” ratings for speech understanding for talkers from the side/back were: Significantly better with the sensor “active” Better with the sensor active, but not significantly so The same for when the sensor was active or turned off Better with the motion sensor “off”
6. In laboratory research, when speech-in-noise testing compared the Narrow Directionality of the Signia Experience to the Signia Nx, the findings were: The Xperience product was significantly better The Xperience product was better, but not significantly better There was no significant difference between the two products The Nx product was significantly better
7. An advantage of EMA assessment compared to traditional written outcome questionnaires is: More samples for each item User memory is not as much of an issue Samples are more representative of users real-world experiences All of the above
8. When the EMA findings were analyzed for speech understanding in background noise while moving, the highest average ratings were found for: In the home On the street In a building (other than home) Outside
9. When the EMAs were analyzed for satisfaction for speech understanding while walking on a street, the mean satisfaction rating was: 68% 78% 88% 98%
10. When the EMA satisfaction ratings for “speech in noise” were evaluated, and compared to recent EuroTrak findings, the results were: About the same as the EuroTrak findings About 5% better than EuroTrak findings About 10-15% better than EuroTrak findings >15% better than EuroTrak findings
