Comtek Digital Auditory FM Trainer

The Comtek Digital Auditory FM Trainer is a wireless auditory assistance system that includes a smart mic option, which optimizes performance in a classroom setting. To use, the teacher simply speaks through the M-216 transmitter and the PR-216 receiver's Smart-Mic automatically prioritizes the teacher's voice over environmental sounds. When the teacher is not speaking, the Smart-Mic immediately activates the environmental microphone on the PR-216 receiver, allowing fellow students comments and questions to be heard.

The Comtek Digital Auditory FM Trainer is an extended-fidelity FM system that brings out speech clarity, incorporating special noise reduction circuitry to increase the speech clarity of the FM signal. The system takes special advantage of current digital hearing aid technology. It works as a remote microphone, overcoming common listening problems for those with hearing loss: background noise, reverberation and distance from the speaker.

A higher signal-to-noise ratio plus a higher frequency response of the FM signal work together to maximize the performance of hearing aids, cochlear implants, and earphones. In addition to t-coil hearing aids, the user wears the personal receiver and neckloop. If hearing aids are not used, the receiver and headphones may be used instead of the neckloop.

An FM system transmits sound via radio waves (frequency modulation) from the speaker's microphone to the listener's portable receiver.
