In select classrooms on campus, you may see an image with an ear on it. This indicates that this room has a hearing system. These systems are usually stored in a closet near the classroom. Check with the facilities person for your building to get the system.
The hearing system works similarly to ones you may have seen in a movie theater. Audience members will use the pack with headphone which will amplify the lapel-style microphone when worn by the instructor.
These systems are available in large lecture hall rooms such as Strong 101, Strong 103, Strong B1, Mossman 102, Mossman 202, and Mossman 212.
