Wireless Connectivity in Hearing Aids

---

1.  What percentage of clinicians nationally report routine use of real ear aided measures? 1/2 1/4 2/3 1/3

2.  What criteria must be met prior to recommending wireless technology? Deciding which FM frequency should be used. Deciding whether a loop system is preferable to infrared. Assuring maximum aided audibility and measuring speech understanding in noise. Measuring telecoil sensitivity in the hearing aid.

3.  Which of the following is true for hearing aid users? The hearing aid is the foundation of all wireless technology. The wireless system recommended is the foundation of all wireless technology. Tinnitus can mask the benefits of wireless technology. The telecoil is the foundation of all wireless technology.

4.  Which of the following is true about real-ear aided measures? The hearing aid brand is the critical determinant of hearing aid user success. Best-practice real ear aided programming can significantly improve speech understanding in noise. Manufacturer's first-fit is equivalent to best-practice real ear aided programming. A good telecoil on the hearing aid obviates the need for real-ear aided programming.

5.  How might the data-driven audiologist determine if the hearing aid user might encounter difficult listening situations? By imagining the noise levels in various environments the hearing aid user might encounter. By questioning the hearing aid users' spouse or family members. By using the signal to noise ratio measurements provided in refereed journals and administering a well-researched user self-report survey. By measuring the directivity index for the hearing aids' microphones.

6.  Which wireless system for auditorium use was rated the highest? FM Infrared Electromagnetic induction (loop) Bluetooth

7.  Which wireless system is preferable for a conference center with 20 meeting rooms where participants change rooms every hour? FM Infrared Electromagnetic induction (loop) Bluetooth

8.  Which wireless system is preferable in a single meeting room housing 100 hearing aid and cochlear implant users? FM Infrared Electromagnetic induction (loop) Bluetooth

9.  The unaided and aided signal-to-noise ratio (SNR) loss on the QuickSIN test provided the best predictors of hearing aid success in: A work setting Outdoors Daily living None of the above

10.  Which statement is documented by meta-analysis of large-group data in peer-reviewed journals? Audiology services are inaccessible. Hearing aids can be properly fit at home by the individual in just a few hours. Hearing instrument specialists charge less than audiologists and can teach appropriate hearing aid use in less time. None of the above
