Hearing loop audio induction system
- Printacall Communications Technology
For people who are hearing impaired, a hearing loop audio induction system is of great benefit. Very few people understand that hearing aid wearers do not always receive clear reception, even though good Public Address or Amplification Systems are present. Nor do they know that when a HEARING LOOP system is incorporated in the amplification system, a hearing aid wearer will benefit with clear reception.
A hearing loop consists of a microphone, an amplifier and, in the place of a loudspeaker, a coil of wire placed around the room. Sound waves from the speaker’s voice going into the microphone are changed into an electric current, amplified, and then sent through the coil which emits a magnetic field in the room. The field is picked up by the “T” switch of a hearing aid, amplified, and converted back into sound. Hearing aid users sitting within the loop system can pick up the speaker’s voice or other auditory stimulus with a minimum of distortion and no background noise simply by turning on the “T” switch on their hearing aids. The loop is fully adaptable to television, radio, stereo, tape recorder or movie projector.
Printacall has over 25 years of research and development of loop design and installation with the objective of providing hearing impaired people with correctly functioning loops.
