Some deaf people will support what they hear through their hearing aid or cochlear implant (CI) with an FM (frequency modulated) system. This is a wireless system that requires that the speaker – in the case, you the teacher – wears a transmitter, which is often a small microphone. The deaf student wears a receiver that interacts with his/her hearing aid or CI. Through radio waves, your voice is transmitted directly to the deaf student.
