This standard specifies requirements for the field strength in audio-frequency induction loops for hearing aid purposes, which will give adequate signal-to-noise ratio without overloading the hearing aid.

The justification to the committee was pretty straightforward.

The hearing loop is the only system that is directly compatible with hearing aids by use of the telecoil. Ask any hearing loop user see testimonials here and they will wholeheartedly agree: The following test report forms are related: The IEC induction loop standard specifies the allowable isc background noise, the maximum field strength of the signals, and the frequency response of the magnetic field in an induction hearing loop.

The clarity and understanding is excellent in those loops. Find Similar Items This product falls into the following idc. Do you need a multi-user copy? Related publications IEC You are commenting using your Twitter account.

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 The use of hearing loops is different than that of the typical FM or IR systems that require the user to pick up a generic intermediary device 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.
