Hearing Loop solutions offer individuals with the “invisible disability” of hearing loss the ability to experience full, rich interactions in just about any setting. Listen’s Hearing Loop solution delivers intelligible sound directly to an individual’s T-Coil hearing aid creating a personalized listening experience.
Users can enjoy a discreet listening experience without background noise, competing sounds, reverberation and other acoustic distortions that reduce the clarity of sound. Hearing Loops can be installed in a variety of environments to benefit those that need hearing assistance.

How Do Hearing Loops Work?

A hearing loop system transmits an audio signal directly into a (Telecoil or, T-Coil equipped) hearing aid via a magnetic field, greatly reducing background noise, competing sounds, reverberation and other acoustic distortions that reduce clarity of sound.

This diagram illustrates how they work.

Audio Inputs (1), either from an existing audio source such as a P.A. system or from dedicated microphone inputs feed an audio signal into an Induction Loop Driver (2). The driver produces a current into a Loop 3or series of loops. As the current flows through the cable it creates a Magnetic Field (4) in the required area – careful loop and driver design ensures that the vertical component of the field is even and free of dropouts and dead zones wherever the user might be. Inside most Hearing Aids (5), a small coil known as a Telecoil (6) 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.

How Do Hearing Loops Help?

People who suffer from hearing loss - the unseen disability - require more than just increasing the volume of sound into their ears. The loss of hearing is generally associated with the neurological processing of information in the brain. People with a normal range of hearing require a signal -to- noise ratio of 6dB for a reasonable level of intelligibility. This represents quite a noisy background, which might be reverberation, air conditioning, ventilation systems or background noise such as a crowd of people. 

When a person loses about 80% of their hearing, they generally need a signal -to- noise ratio of 15 to 20dB. This can be difficult to achieve unless the wanted signal is taken straight from the basic source and transmitted directly through the hearing loop system, avoiding any reverberation or additional ambient noise. 

In challenging ambient audio situations, such as public ticket counters, information and help points, etc., these can be the worst areas for listening. Sometimes, even in churches, theatres and lecture / conference rooms, there is often sufficient degradation of the signal to seriously affect intelligibility. In most situations it is impractical to issue any form of separate receiver and the use of the individual's hearing aid is a major step to bringing people with hearing loss back into full contact with their environment. Only hearing loop systems are capable of doing this.
