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.

TC 29 – Electroacoustics rss. Throughout this standard, it is assumed that the hearing aids used with it conform to all relevant parts of IEC The following test report forms are related: Induction-loop systems for hearing aid purposes.
Our prices are in Swiss francs CHF. The hearing loop is the only system that is directly compatible with hearing aids by use of the telecoil. 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.

You may experience issues viewing this site in Internet Explorer ice, 10 or 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.
This means that hearing loop users depends on proper installation of a hearing loop. For more specific information regarding the loop standard see here and here. While some users have a volume control to adjust for a low loop signal level, none have iiec capability to compensate for a poor lec, noisy or uneven signal response.
