IEC 60118 4 PDF

​When choosing a loop system installer, it is important to choose a company who provides the hearing loop installation. IEC standard. IEC consists of the following parts: Part 0: Measurement of the performance characteristics of hearing aids – Part 4: Induction-loop systems for hearing. Calibrating Induction Loop Systems to IEC Standards. Frequency response: Hz ±3dB relative to Hz Field strength: mA/m peak.

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.

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 For more specific information regarding the loop standard see here and here. The justification to the committee was pretty straightforward.

The hearing loop is the only system that is directly compatible with hearing aids by 6018 of the telecoil. While some users have a volume control to adjust for a low loop signal level, none have the capability to compensate for a poor quality, noisy or uneven signal response.


It is the IEC standard that specifies these qualities and without it there can be no guarantee.

BS EN IEC 60118-4:2015+A1:2018

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. This means that hearing loop users depends on proper installation of a hearing loop.

Ask any hearing loop user see testimonials here and they will wholeheartedly agree: Hearing loops that meet the IEC standard transmit clear, strong, and noise-free audio to their hearing aids.

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. Poorly installed loops add frustration and doubt: These problems are of no concern in loops that meet the IEC standard.

The clarity and understanding is excellent in those loops. I came armed with nearly 30 letters of support written by consumers like Ed Ogiba and Ellen Semel, by audiologists such as Dr.

Linda Remensnyder and Dr. The proposal was submitted by Sharon Toji who represents the Hearing Loss Association and is a voting delegate at these committee meetings.
