Hearing Loop at Oak Grove Baptist in Benton Arkansas
Oak Grove Baptist Church in Benton Arkansas is pleased and excited to announce that we’ve installed a Hearing Loop in our church. That means if you use a hearing aid, you can benefit from Induction loop technology. All music and songs and sermons will be loud and clear and broadcast though the loop straight to your hearing aid!.
Here is some information about hearing loops.
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.
