1. The space where the loop will be installed should be checked to discover if a loop can be successfully installed. One of the easiest way to do this is have a person with an active T-coil hearing aid go around the space and see if excessive interference can be heard. If there is no one available with a t-coil hearing aid, the space can be checked using our PLRAMP in the Loop Receivers above.

2. Once establishing that the space is clear of excessive interference measure the distance around the perimeter and the space square feet or square meters.

3. With the two measurements choose the right size of system. Obviously the larger the system the large the loop amplifier needs to be. If there is a lot of metal near the loop (such as concrete rebar, reinforcing bar or steel stud construction) a more powerful loop amplifier will likely be needed.
