The Williams AV FWT 001 is part of Williams AV's induction (hearing) loop product line, which broadcasts an electromagnetic audio signal picked up directly by the telecoil built into most hearing aids and cochlear implants. Because the signal is received by the hearing aid itself, loop users need no separate receiver at all, which is why induction loops are widely specified at ticket counters, courtrooms, and worship or meeting spaces for ADA-compliant hearing access. It's a core building block of a loop installation, used alongside loop wire, an amplifier, and a field strength meter to verify ADA-compliant coverage.
