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.

BS EN IEC 60118-4:2015+A1:2018
TC 29 – Electroacoustics rss. The standard also specifies the minimum frequency response requirements for acceptable intelligibility.
The hearing loop is the only system that is directly compatible with hearing aids by use of the telecoil.
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.
Induction-loop systems for hearing aid purposes. Ask any hearing loop user see testimonials here and they will wholeheartedly agree: This third edition cancels and replaces the 6018 edition published in I came armed with nearly 30 letters of support written by consumers like Ed Ogiba and Ellen Semel, by audiologists such as Dr.
While some users have a volume control to adjust for a low loop signal level, none have the iev to compensate for a poor quality, noisy or uneven signal response. Preview Abstract IEC Email required Address never made public.

Throughout this standard, it is assumed that the hearing aids used with it conform to all relevant parts of IEC To find out more, including how to control cookies, see here: Do you need a multi-user copy? Be sure it includes Bluetooth as well as Telecoil Wireless Technology. Please download Chrome or Firefox or view our browser tips. Related publications IEC This standard does not specify requirements for loop isc amplifiers or associated microphone or audio signal sources, which are dealt with in IECor for the field strength produced by equipment, such as telephone handsets, within the scope of ITU-T P.
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 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.

Addition of Annexes G, H and I where more information is provided about practical considerations and methods of measurement. The levels it sets for hearing loop performance are tied to the requirements for telecoil iex in hearing aids which will appear shortly in a new edition of the hearing aid standard IEC The faster, easier way to work with standards.
The clarity and understanding is excellent in those loops. This website is best viewed with browser version of up to Microsoft Internet Oec 8 or Firefox 3.
