The hearing loop helps individuals who use hearing aids that are equipped with T-coils hear sounds from a Public Announcement System directly and clearly in the hearing aids, because it reduces or cuts out background noise. T-coils are standard in many hearing aids today.
A hearing loop provides a magnetic, wireless signal that is picked up by the hearing aid when it is set to ‘T’ setting. The loop system consists of a microphone to pick up the spoken word; an amplifier which processes the signal is then sent through the final piece; the loop cable, a wire placed around the perimeter of a room or sanctuary to act as an antenna that radiates the magnetic signal to the hearing aid.
When a hearing aid user selects the ‘T’ setting; the individual can pick up the sounds spoken into the Public Announcement system’s microphone instead of the hearing aid’s internal microphone. This results in improved speech understanding / intelligibility because the listener receives a clear signal without background noise.
When a hearing aid is set to “T”-coil, the instrument becomes a personalized speaker in your ear for the sounds that are picked up by the microphone of the PA system. That way sounds are heard clearly, without distortion or background noise pick-up.
