Evaluation of Modern Remote Microphone Technologies

---

1.  Gyroscopes/accelerometers in a remote microphone allow for: finding a lost device connectivity with apps automatic switching of microphone modes to account for different use scenarios locating a good fishing spot

2.  Which type of remote microphone would be compatible with most hearing aids? Universal system Accessory remote microphone system Truly wireless accessory remote microphone system All of the above

3.  Which remote microphone technology contributes to improved SNR in noisier environments? Directional microphone Fixed gain Omnidirectional microphone Radio frequency transmission

4.  What condition was not evaluated in this investigation? The hearing aids in a sound booth setup The hearing aids with a universal remote microphone system in a sound booth setup The hearing aids with a universal remote microphone system in a shopping mall environment. The hearing aids with a truly wireless remote microphone system in a sound booth setup

5.  What is not true of the results of this investigation? The "Quiet" condition showed the most benefit with all remote microphone systems Use of each remote microphone system provided better speech recognition in quiet and in noise relative to the hearing aid alone condition. At moderate to high noise levels (60-75 dBA), the remote microphone systems with directional microphones provided better speech recognition in noise than the remote microphone system with an omni-directional microphone. At higher competing noise levels (70 and 75 dBA), use of an adaptive-gain remote microphone system provided better speech recognition than what was obtained with use of a fixed-gain remote microphone system.

6.  Using the adaptive gain remote microphone in higher noise levels resulted in a typical performance increase of: 80 percentage points no difference 100 percentage points 20 percentage points

7.  Universal remote microphone systems, such as the Roger X, can: Be coupled to hearing aids with direct audio input Be coupled to the ReSound Multi Mic Stream to multiple users of ReSound hearing aids when a receiver is coupled to a single ReSound Multi Mic All of the above

8.  Non-audiological considerations that might influence the choice of remote microphone system include: Cosmetics/aesthetics Ease of use Manual or automatic activation of the remote microphone All of the above

9.  The scope of benefit provided by use of a remote microphone system can be increased by: Using it in the car Prescribing a system that can connect to other electronic devices Turning it sideways Regularly replacing the battery

10.  Differences between the ReSound Mini Mic and the ReSound Multi Mic do not include: A directional microphone in the ReSound Multi Mic Direct audio input in the ReSound Multi Mic Streaming capability to an infinite number of ReSound hearing aids simultaneously Automatic switching of microphone mode depending on position of the ReSound Multi Mic
