Wireless Communication in Hearing Aids

---

1.  Which one of the following wireless options requires a telecoil-equipped hearing aid regardless of manufacturer? FM Infrared Loop Bluetooth

2.  Which one of the following technologies always requires the hearing aid user wear an external device? FM Infrared Loop Bluetooth

3.  Which of the following can only work indoors? FM Infrared Loop Bluetooth

4.  Before determining necessary wireless options for a patient, the audiologist must ensure: the patient has baseline skills in lipreading that aided audibility has been optimized according to probe microphone verification the patient has been fit with the manufacturer's "best fit" algorithm the patient has completed auditory training

5.  According to the rating scale presented in this presentation, which of the following technologies has the best ease of use? Bluetooth FM Infrared Loop

6.  According to the presenters, a challenge for using wireless connectivity for telephone use is: the hearing aid wearer does not notice improvement over acoustic coupling speech recognition performance is poorer for the person with hearing loss than without using hearing aids at all on the phone there are not enough compatible phones on the market with a Bluetooth connection there are dropouts, distortions and artifact for the other party (not using the technology)

7.  When an external mic is provided to one of our patients our data show most typically they will use that microphone > 50% of the time 30-40% of the time 20-30% of the time less than 10% of the time spent wearing hearing aids

8.  Kochkin et al (2010) have shown that one of the most important variables associated with hearing aid user satisfaction is which of the following? Multiple Environment Listening Utility Hearing Aid Compression Scheme Number of Hearing Aid Channels Effective use of frequency lowering

9.  An SNR of ____ or better is recommended for optimal hearing in a school classroom: +5 +10 +15 -10

10.  Which of the following best describes our experience with patients using loop systems? If you make the loop readily available most people with telecoil equipped hearing aids will use it If you combine proper training of loop systems and hearing aids people will make use of loop systems While properly installed loop systems dramatically enhance speech recognition and are readily available we do not see a lot of people using them. Our patients prefer infrared to loop systems
