Induction loops reduce or cut out background noise for people who use hearing aids or loop listeners, allowing those who have a hearing impairment to hear better.

### How do induction loops work?

Induction loops include a loop of wire which is installed discreetly around a certain area. The wire is fed with a current from a loop amplifier, which gets its signal from a microphone or from a direct connection to another sound source. As the current travels through the wire, it creates an electromagnetic field corresponding to the sound. This can be picked up by those within the area of the loop who are wearing a hearing aid switched to the 'T' position.

### What are the different types of induction loops?

Induction loops differ depending on where they are being used and the size of the area that needs to be included within the loop. They can be used in large spaces like theatres and concert halls, while counter top versions can be used in restricted areas of communication such as banks or ticket offices.



Induction loop amplifiers are listening devices that provide hearing assistance to hearing-aid users and others with hearing impairments.
