Assistive listening devices refer to hard-wired or wireless transmitting/receiving devices that transmit sound from the microphone directly to the listener, minimizing the negative effects of distance, noise, and reverberation on clarity.
The devices transmit sound directly to the ear, but also can employ ?teleloop? attachment accessed by the telephone switch in some hearing aids and cochlear implants.
