Hearing Aid Induction Loops

In order to make public buildings more accessible to hearing aid users, Hearing Aid Induction Loop systems must be fitted.

Loop systems allow audio, speech and/or music, to be transmitted directly to hearing aid users who are within the perimeter of the room where the loop is fitted.

Hearing aid induction loop systems consist of the induction loop itself, literally a loop of wire that runs around the perimeter of the room, and an amplifier designed specifically for powering the induction loop. The amplifier alters the current flowing through the induction loop according to the audio signal being recieved. This causes the induction loop to create a magnetic field in a similar way to a transmitting aerial. The magnetic field can then be recieved by a small coil fitted inside a hearing aid.

The induction loop can usually be hidden away above false ceilings, under carpets or around skirting or dado rails, to avoid spoiling the appearance of the building.

The induction loop amplifier has a blue front panel.

The amplifier can be mounted in a rack and connected to an existing audio system or a new system can be supplied as part of the installation.
