Audio-frequency induction loop systems allow hearing impaired
people to hear more clearly. Most hearing aids have a â€˜Tâ€™ or
â€˜MTâ€™ switch which allows them to pick up the electromagnetic
field generated by an induction loop system. The hearing aid
converts this signal into a sound suited to its userâ€™s
specific hearing requirements. Any person with a hearing aid
positioned within or near the loop (see example schematics
below) can hear the loop signal by switching their hearing aid
to the correct position, allowing them to participate more
effectively in general conversation, ordering goods or services,
listening to public performances, etc. Why use an Audio
Induction Frequency Loop? People who suffer from hearing loss
require more than just increasing the volume of sound into their
ears. The loss of hearing is generally associated with the
brainâ€™s neurological processing of information. For people
with normal hearing, a signal to noise ratio of 6dB is required
for a reasonable level of speech intelli
