About Hearing Loops

Loop today. Hear Tomorrow! Arkansas Loops is a subsidiary of Saline Audiology.

Hearing Loops can be used in a commercial or residential setting and work in any style of building. In both the commercial and residential systems, the loop signal is picked up by a small coil of wire inside the hearing aid called a T-Coil.

If you see this sign, an Induction Hearing Loop is installed in the facility.



The signal from the loop plays through the customized hearing aid programming. An Induction Loop system eliminates background noise and echo by sending the audio signal directly to the hearing aid.

T-Coil equipped hearing aid users with loop systems enjoy crystal clear customized sound. The sound is mixed and adjusted by the hearing aid to compensate for the user’s hearing loss, giving as close to true sound reproduction as possible.


In a commercial setting, an Induction Loop system transmits the signal from your microphone or sound system through an easily installed wire that “loops” around the listening area.


A residential InLoop system transmits the signal from your TV or home theater through an easily installed WIRED LOOP or a small PERSONAL InLOOP PAD.

What is an induction loop?

aka hearing loop, audio loop, audio frequency induction loop-system (AFILS)

Induction loops are prominent in Europe and awareness in the U.S. is on the rise. An induction loop is very simply a loop of wire plugged into an amplifier to create a magnetic loop. This magnetic signal is then sent to the T-coil in a hearing aid for clear sound without interference.

There are currently three wireless technologies: 1) Infrared, 2) FM and 3) Audio Induction Loop. Infrared and FM systems have limits due to varying frequencies and require a “receiver” such as a headset or neck loop. Induction loops are very simple and consist of three basic parts – an amplifier, microphone and a very thin loop wire. The loop wire is run around a room, sanctuary or auditorium, and connected to the amplifier, which is then routed to a TV, PA system, radio or microphone. Induction loops do not require any external receiving units – only a T-coil in a hearing aid. Headsets compatible with the induction loop are available to assist those without hearing aids or T-coils.

How does a hearing loop work?

The loop creates a magnetic field that is picked up by the T-coil in a hearing aid and is converted to audible sound sent from the amplifier. When the T-coil is activated in the hearing aid, feedback and background noise is eliminated or greatly reduced which results in a clearer signal from the source of the sound.

What is a t-coil?

A t-coil, or telephone coil, is a small copper coil in most hearing aids that picks up a magnetic field from the loop and converts it into electrical energy. This is similar to how a microphone converts sound waves in to electrical energy. By switching the hearing aid to the “T” position, the electromagnetic field is detected. The strength of that field depends on the size of the t-coil, energy or power of the magnetic field and the relative positions of the t-coil. For telephone usage, the t-coil is best when horizontal relative to the phone receiver; however, the best reception for loops is a vertical orientation. So many audiologist set the t-coil at a 45 degree angle to work with both the telephone and induction loops. It is very important for your audiologist to take as much time programming and evaluating the t-coil as the microphone for optimal satisfaction of the user. An M/T position on the hearing aid allows the wearer to hear through the t-coil but also hear through the microphone, which is preferred by some so they can hear the person next to them or others in the room in addition to the direct signal from the loop. A manual “T” or “M/T” switch is a must to allow the user control over the programs.

Be advised that many hearing aids are fitted with a t-coil but the audiologist may not have activated the program or the volume may be set very low and need to be adjusted to hear satisfactorily through a loop. Some hearing aids that do not have a t-coil may be retro-fitted to experience the clear sound through loop in your home or in public venues.

Where are induction hearing loops appropriate?

Anywhere that has a Sound Source

Hearing loops are appropriate for two environments: transient/short term and extended/permanent. Extended time induction hearing loops are appropriate for public venues (commercial use), such as churches, auditoriums, meeting rooms and concert halls. Loop systems are available for transient locations such as bank windows, pharmacies, post offices, hotel reception desks, airport counters, information booths, etc. Even tour buses, taxis and trains can be looped. We analyze your public venue to determine the best design for you.

Why induction hearing loops?

Induction loops improve listening clarity for those with hearing aids. The hearing aid must have a T-coil but estimates are that about 65 to 70 percent of hearing aids in use today have T-coils. Nearly all new hearing aids now have T-coils, so eventually all hearing aids will utilize the T-coil technology. Installation of induction loops is a very cost-effective way to improve communication for the hearing impaired population, while conforming to ADA guidelines.

Advantages of a loop system:

Businesses or venues that install loop systems have virtually no maintenance on the system and do not have to purchase or maintain/sanitize/repair headphones such as those used with infrared or FM systems.

There is no limit as to the number of users of the system – it is virtually unlimited.

Users do not have to “advertise” their disability by using headphones – they only have to turn on their T-coil – so there is no stigma attached to the usage of the loop system.

Users benefit from the loop technology AND their customized hearing aids for the best possible hearing experience. The loop system helps the hearing aid do its job.

Loop technology uses a universal standard system any T-coil equipped instrument user can use at home in a TV room or worldwide.

All hearing aid T-coils work with all loop systems. Cochlear implants also have T-coils.

Listeners use hearing aids they own. Sound is optimized for their personal hearing loss and needs.

Improved clarity and understanding benefits businesses and individuals.

A loop system has a reasonable cost to install with minimal or no maintenance.

Loop systems don’t require you to purchase, maintain, and replace portable receiving units.

Portable units can be purchased for those without suitably equipped hearing aids at $145 each. We include one receiver for monitoring purposes. ADA requires headsets for 1% of seating occupancy so a 400 seat room would need 4 loop receivers.

ADA compliance

Our experience is that loop systems are far more likely to be used – and increasingly used – once installed.

What does a loop system cost?

Commercial loop installations vary from building to building, depending on construction, floor coverings, electrical interference, size, etc. A customized quote will be provided for each building and our professional installers will typically complete the installation in a couple of days. A professional installation is a must to ensure a quality system with even sound across the room.

How is a loop installed?

A loop system from Saline Audiology is installed by professionals. A test loop may be run to make sure the proposed design will work before we do the permanent installation. Installations are required to meet the international standard IEC 60118-4, which defines the magnetic strength field, frequencies and measurement requirements. Installations are tested with a FSM (field strength meter) to confirm compliance.
