The amplified signal, instead of going to a loudspeaker, is fed to a closed loop of cable placed in or around the room using a constant current amplifier.
The current flowing through the loop generates a magnetic field that radiates in the space around the loop cable. Any lines of magnetic flux that pass through a hearing aid's telecoil will generate a current in the coil that is then converted back to audio and fed into the listener’s ear.
It is important to note the magnetic field will ‘bleed’ outside the perimeter of the loop, so a loop system cannot be considered confidential. Ways of reducing overspill can be discussed with our team, should you have a particular project.
