A hearing loop, sometimes referred to as an induction loop, T-Loop or an audio frequency induction loop (AFIL), is an assistive listening system that provides access to facilities for those who experience hearing loss and use a hearing aid. It takes a sound source and transfers it directly to a hearing aid without background noise, interference or acoustic distortion.
Click below to download a copy of our guides, which feature a simple explanation of how hearing loop systems work and answers to the most commonly asked questions.
An induction or hearing loop system transmits an audio signal directly into a hearing aid via a magnetic field. This greatly reduces background noise, competing sounds, reverberation and other acoustic distortions that reduce clarity of sound.
This diagram below illustrates how hearing loops work.
The number of people that can fit in the ‘looped’ area at the same time is the only limitation.
Hearing aid wearers don’t suffer the inconvenience of asking for and wearing a headset that marks them out as hard of hearing; and expensive receivers are not required.
Although Hearing Loops are an inherently simple technology, care should be taken in their design, specification and installation. Ampetronic can support you in developing a loop system that conforms to the International Standard and is of optimum benefit to the end user.
Selecting a loop solution, that will adequately meet the needs of a hearing aid user, can be easily determined by asking just a few simple questions:
What type of hearing solution is required?
An area coverage loop, for use in a hall, theatre, meeting room or similar
a service point loop solution, for use with a retail counter or reception desk?
Area coverage hearing loops, as the name suggests, cover an area in which multiple people can access the loop signal simultaneously.
The type of area loop system chosen will depend on:
|Room dimensions||Floor construction||Adjacency and privacy||Recommended solution||Recommended loop drivers|
|Less than 4m across shortest dimension||or||floor has no metal in structure||and||no requirement||Ampetronic Perimeter loop||C5-1|
|Greater than 4m across shortest dimension||and||floor has metal in structure||and/or||risk of overspill||Ampetronic MultiLoop™||C5-2|
For service points and intercoms:
Dealing with background noise when faced with a busy reception desk, ticket office or audiovisual interactive display can be a challenge for a person with hearing loss. Distance from a
receptionist can also cause frustration.
For service points and help desks, a preformed loop and microphone combined with Ampetronic CLD1 service point amplifiers provide a person with hearing loss clear, intelligible sound direct to their hearing aid.
Ampetronic TalkPerfect offers effective communication through physical barriers, supporting privacy and security in a robust and easy to use system.

|Service Points||CLD1, CLD1-AC|
|Speech Transfer System||TalkPerfect|
|Door intercoms||HLS-2C Active loop panel|
Hearing loops can be beneficial in a very wide range of environments, from large venues such as theatres and conference facilities, to teaching spaces, meeting rooms and one-to-one communications such as ticket counters and reception desks. They are the only effective solution to assist hearing aid users in transport environments, in vehicles, terminals and stations.
The cost of a Hearing Loop system is proportional to the size and complexity of the loop design, the associated amplifier(s) and the accessories required.
A ‘fit-for-purpose’ retail/reception desk or home TV room loop should typically be less than £300 plus any installation fees, whereas a professional system for a large venue may cost thousands of pounds proportional to the size of the venue and other audio visual equipment that may be installed.
It is worth remembering that the cost of installing a Hearing Loop in a medium size venue, such as a place of worship, will often be less than the cost a single user has paid for their professionally fitted hearing aids.
