20Q: Amplification Options for Unilateral Hearing Loss - A Case for CROS

---

1.  Which type of noise is most common in modern classrooms? No noise (classrooms are pretty quiet) Directional noise (comes mostly from one direction) Surrounding noise (comes from lots of different directions simultaneously) Steady state noise (comes from air conditioners and refrigerators)

2.  Current recommendations for managing children with limited useable hearing unilaterally (LUHU) suggest remote microphone (RM) systems provide the most benefits and we should be cautious with contralateral routing of signals (CROS) systems. These recommendations were based primarily on laboratory studies, which evaluated a limited set of listening conditions. Importantly, most of the conditions included which type of noise? No noise was used Directional noise Surrounding noise Steady state noise

3.  The recent laboratory evidence out of Vanderbilt University Medical Center using noise surrounding a listener and multiple talkers of interest demonstrates that CROS systems: Improve sentence recognition performance for talkers in multiple locations Impair sentence recognition performance for talkers in multiple locations Do not affect sentence recognition performance for talkers in any locations Allow participants to achieve similar sentence recognition performance as with a RM system

4.  Which of the following is the best preferential seating recommendation for a student with LUHU? The front row The back row It depends on the student's intervention Next to the door

5.  The potential benefits of CROS systems for students with LUHU have been demonstrated: In the laboratory only With questionnaires only With questionnaires and in the laboratory Nowhere, RM systems are the only way to go
