System Design & Training
A Hearing Loop doesn’t exist in a carton or on a warehouse shelf; but only when installed, operating properly and delivering value to listeners. So, Listen Technologies applies a systems view to ensure the best possible solution is delivered to our customers. Listen Technologies can support you with design consultation and multiple levels of training to ensure the best quality solution is delivered to meet the needs of your particular application. Contact Listen for full details. More on Training >>>
How Do Hearing Loops 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.
