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…
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….
The International Hearing Access Committee (IHAC) aims to estimate the time a transition from the existing audio transmission to telecoils via hearing loop (HL) and other assistive listening systems (ALS) to a platform of digital audio streaming direct into hearing aids, will likely take.
Assistive listening systems have been widely available since the 1930s, the most successful of which have been the hearing loop and telecoil combination.
A standard is an agreed way of doing something such as making a product, managing a process, delivering a service or supplying materials.
Standards are important because they ensure that equipment from different manufacturers will work together, and that users can benefit from services.
