Looping Basics

 What Is a Loop?

A hearing loop is a copper wire that circles a room and is connected to the sound system and microphone.  The loop electromagnetically transmits the desired sound (usually referred to as “the signal”) from the microphone  over the copper wire. The electromagnetic signal is picked up and received by a small copper coil called a telecoil (or T-coil), a component found in most hearing aids and cochlear implants.

Persons with hearing loss who are able to use hearing aids benefit greatly if their hearing aids are equipped with T-coils. In a looped room, the desired sound (often referred to as the “signal”) is transmitted directly from the source of the sound to the person’s hearing aids via the T-coil.

The green line represents sound transmitted in a looped space from the speaker directly to the hearing aids of an individual, greatly increasing clarity and intelligibility.

Loops can be integrated into electronic devices such as televisions, and can be installed in private as well as public spaces.

HLAA’s  Get in the Hearing Loop Task Force

Juliette Sterkens presents a program to Boston Chapter members and friends about the important role of loops in hearing loss management.

In existence for several years, the mission of the HLAA Get in the Hearing Loop Task Force is to raise awareness of hearing loop/telecoil technology in the United States among both the public and hearing care professionals, and to promote the availability of hearing loops in all public venues.

Among the action items being addressed by the task force are:

  • Supporting the establishment of standards and guidelines for looping systems and other ALDs
  • Establishing systems for identifying looped venues and facilities
  • Establishing systems for identifying qualified installers of looping systems
  • Raising consumer awareness about the value of looping and all assistive listening systems. (This is the area where HLAA Chapter participation is encouraged and the reason the “Looping Toolkit” was developed).
  • Advocating for looping systems with providers. HLAA Chapter participation is encouraged at the local level in addition to advocacy from the national office regarding professional associations like the International Hearing Society and the American Academy of Audiology.
