This leaflet answers common questions about using hearing loops. If you would like further information or have any worries, please do not hesitate to ask your audiologist.

What is a hearing loop?

A hearing loop, sometimes referred to as an induction loop or telecoil, is a special type of sound system for use by hearing aid users. It provides a magnetic, wireless signal that is picked up by a hearing aid when it is set to the ‘T’ (telecoil) programme.

The hearing loop usually consists of three parts; a microphone to detect the sound, an amplifier to process it and a loop cable, which is placed around a chosen area and acts as an antenna that transmits (sends) a magnetic signal to the hearing aid/s.

How does it work with a hearing aid/s?

Some hearing aids have a copper wire coiled inside them which increases their functionality and can potentially provide users with an enhanced listening experience in difficult listening situations where a hearing loop is installed.

All hearing aids have a microphone that detects sound, an amplifier that processes it and a receiver that delivers the amplified sound to the ear. When a hearing aid has a telecoil, it acts as a microphone when set to the loop programme. This delivers a clearer signal to the wearer as most surrounding sounds are cut out.

Why use a hearing loop?

There are many benefits of using a hearing loop:

  • Sound goes directly into the hearing aid, reducing unwanted background noise and providing clearer sound quality.
  • Used by more than one person at a time.
  • Used by anyone that has a loop on their hearing aid.
  • Improve the user's speech understanding when using a compatible telephone.
  • Makes listening in larger rooms easier.

Where can I use hearing loops in my community?

Most public places now have a hearing loop installed, particularly in areas such as meeting rooms, theatres, places of worship, banks, supermarkets, cinemas, and residential homes.

Do I have the telecoil programme on my hearing aid/s?

At your hearing aid fitting appointment, the telecoil programme may have been added to your hearing aid/s following a discussion with your audiologist.

If you are unsure if the telecoil programme is activated on your hearing aid/s please contact the audiology department on: 020 8375 1117 or 020 8216 4912.

How do I activate the telecoil programme on my hearing aid/s?

Your audiologist will have informed you of any additional programmes on your hearing aid/s and how to change to them.

If you are unsure if the telecoil programme has been activated or how to change to the telecoil programme, please read your instruction booklet or contact the audiology department on 020 8375 1117 or 020 8216 4912 (open Monday-Friday, 9am to 5pm The telecoil programme will work best if you are in an area where a hearing loop is installed, switched on and working. When in public, you may need to speak to a member of staff to check their hearing loop is activated. A hearing loop is usually present in a public place when you see the sign below:
