IHLMA Position on Neck Loops and Cardiac Pacemakers

IHLMA recognises a concern expressed by some medical professionals of a potential for interface with cardiac pacemakers from the magnetic fields that exist in very close proximity to the wiring of a neck loop...

The care and feeding of neck loops for assistive hearing

A neck loop is a personal induction loop about 230 mm in diameter, intended to be used with a static or hand-held source of audio signals and transmit them magnetically to the user's one or two hearing aids equipped with telecoils....
