How Loop technology works

1 » Audio inputs, either from an existing audio source such as a public address system or from dedicated microphone inputs, feed an audio signal into an Induction Loop Amplifier.

2 » The amplifier drives a current into a loop or series of loops.

3 » As the current flows through the cable, it creates a magnetic field in the required area.

4 » Careful loop and amplifier design ensures that the vertical component of the field is even and free of dropouts and dead zones wherever the user might be.

5 » Inside most hearing aids, a small coil known as a telecoil picks up the magnetic field signal, which is amplified into a high quality audio signal delivered directly to the ear of the hearing aid user.
