Hearing Loops – What and Why

Hearing Loops benefit the hearing impaired

Due to background noise, reverberation and other interference, Hearing Aid and Cochlear implant wearers do not always receive clear reception, even though good Public Address or Amplification Systems are present. When a HEARING LOOP system is in place, those with hearing devices fitted with a “T-Switch” (Telecoil) are able to tune in directly to the loop, giving them vastly improved reception. Hearing Loops are preferred by most hearing impaired people and building owners to any other method of hearing augmentation.

What Is a Hearing Loop?

A hearing loop system consists of a special amplifier and a coil of wire placed around the room in precise formation. Signals from the amplified sound source (e.g. microphone, music, tv, etc.) are sent through the coil which emits a magnetic field in the room. The field is picked up by the “T” switch, amplified, and converted back into sound. Hearing aid users sitting within the hearing loop system can pick up the amplified sound without reverberation or background noise.

Hearing Loops allow T-switch enabled device wearers to connect directly to the sound source

Why most don’t work!

Unfortunately, too many of the Hearing Loops in public spaces have been poorly designed and/or installed, causing customer complaints, refunds and more. Hearing Loops are highly technical, requiring precise measurement and calibration, beyond the skills of most electrical contractors.

ClearaSound has been designing and installing Hearing Loops for over 30 years and we know how important they are to the deaf and hearing impaired. We’re often called in to fix the issues of faulty Hearing Loops! It is much simpler (and less expensive) to get an expert to do it right the first time.

Compliance Is Important

  • The National Construction Code (NCC)/ Building Codes of Australia (BCA) requires a minimum of 80% coverage for hearing loops systems in public spaces, including theatres, churches, public transport and office buildings.
  • Hearing Loops also help you meet Disability Discrimination Act requirements.
