Those loops allows users to sit anywhere in the seated area and hear the same level of quality and sound broadcast directly to the telecoils in their instruments. The proposal was submitted by Sharon Toji who represents the Hearing Loss Association and is a voting delegate at these committee meetings. By continuing to use this website, you agree to their use. The levels it sets for hearing loop performance are tied to the requirements for telecoil performance in hearing aids which will appear shortly in a new edition of the hearing aid standard IEC Addition of Annexes G, H and I where more information is provided about practical considerations and methods of measurement.

The IEC induction loop standard specifies the allowable magnetic background noise, the maximum field strength of the signals, and the frequency response of the magnetic field in an induction hearing loop.
TC 29 – Electroacoustics rss. The kec of hearing loops is different than that of the typical FM or IR systems that require the user to pick up a generic intermediary 6018 which needs a volume control to accommodate the hearing loss of whomever picks one up; in a loop the hearing aid itself is the receiver and the user benefits from the individualized settings of his or her hearing aid.
