Someone asked me, “When setting up a loop for a small area, does it make a difference if I use a double-wire loop or a single-wire loop when using the Univox 2A system?” Good question.
According to the manufacturer, a double-wire loop is only a bit more powerful than a single-wire loop. So feel free to use either a double-wire loop or single-wire loop, whatever your preference. (The single-wire loop is a bit easier and faster to set up.)
Personally, I like to use the double-wire loop since I use lamp cord for the loop and it already has two parallel wires in it. (It doesn’t do my Scottish heart any good to “waste” the extra wire.)
Tip: When using a loop, it’s always better to have a stronger loop signal rather than a weaker loop signal. That way you can keep the volume on your hearing aid (t-coil) down. With the hearing aid volume down, your t-coils don’t pick up as much interference from things such as nearby wiring in the walls and electrical appliances.
Having a weaker loop signal and turning up your hearing aid volume (in t-coil mode) can give you just as loud a signal as the above method–but you may hear a lot of annoying buzzing at the same time.
If you want an interference-free system (or as close to interference-free as possible), have a “loud” loop while keeping the volume down on your hearing aids. This is particularly important if you already have interference in the room where you have installed your loop.
