NewEarTM High Quality Digital Ear Hearing Amplifier "FDA Approved"
What is a T-coil? A t-coil (telecoil) is a very effective device that can be part of all but the tiniest ear amplifiers (ha's.) It is far more popular in certain other countries where its beneficial uses are many. Do all ear amplifiers have t-coils? No. It is believed that only 30% of ear amplifiers in the USA have t-coils, and many of the people owning such ear amplifiers do not really understand the benefits/uses of t-coils. What does a t-coil consist of? A t-coil is a very small coil of wire built within a ear amplifiers that serves as an antenna which can be activated by the switch on the ear amplifiers when it is set in the "T" position. What is the basic use of the t-coil? The common use of the t-coil is with the telephone. Here, the t-switch is turned on allowing much clearer hearing without feedback. If there is a need for more volume, then the volume control on the aid can be turned up and no feedback occurs resulting in a much clearer amplifiable sound and a more relaxed conversation by people than is obtainable via telephone amplification devices. When on, the t-coil shuts out other background noises. Though some aids allow the regular mike to be on (or off) when the t-coil is on. Some of the other uses of the t-coil; Frequently, when people have meetings their room will be "looped." Meaning, a wire (telephone like) will run around the room, either at the floor or ceiling, exposed or concealed. The wire creates a circle or loop that as it joins itself, it has a short straight piece that has a jack on the end of it that plugs into an output plug on the PA system box. When anything is said into the mike, it sends the sound to the loudspeakers but also through the "loop," creating a magnetic induction field within the loop. This means that anyone in the room within the loop with their T-switch on will be able to hear very clearly all that is said into the mike. Often, even better than people who have normal hearing.
