어떻게 사용합니까?

Use when giving instructions, for student responses, on stage, etc. Those who are hard of hearing would prefer you to use a microphone, even if you are trained to “project.” Some hearing aids can be linked to a microphone that the Classroom Teacher might ask you to wear around your neck. In this case, you may not hear any amplification, but the student wearing the hearing aid will. Speak clearly and remember that you have it on!
