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.

Preview Abstract IEC These problems are of no concern in loops that meet the IEC standard. Hearing loops that meet the IEC standard transmit clear, strong, and noise-free audio to their hearing aids.
Worldwide Standards We can source any standard from anywhere in the world. Accept and continue Learn more about the cookies we use and how to change your settings. 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 6018 the individualized settings of his or her hearing aid.
TC 29 – Electroacoustics rss. For more specific information regarding the loop standard see here and here. It is the IEC standard that specifies these qualities and without it there can be no guarantee. Please download Chrome or Firefox or view our browser tips.

The 6011 loop is the only system that is directly compatible with hearing aids by use of the telecoil. Related publications IEC To find out more, including how to control cookies, see here: Ask any hearing loop user see testimonials here and they will wholeheartedly agree: You are commenting using your Twitter account. Those loops allows users to sit anywhere in the seated area and hear the same level ic quality and sound broadcast directly to the telecoils in their instruments.
The following test report forms are related: 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 Email required Address never made jec.
Fill in your details below or click an icon to log in: The standard also specifies the minimum frequency response requirements for acceptable intelligibility. 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 proposal was submitted by Sharon Toji who represents the Hearing Loss Association and is a voting delegate at these committee meetings. This standard does not specify requirements for loop driver 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.

Ampetronic: hearing loop performance standards IEC
The faster, easier way to work with standards. 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. This edition constitutes a technical revision which includes the following significant technical changes with respect to iev previous edition: Addition of Annexes G, H and I where more information is provided about practical considerations and methods of kec.
Throughout this standard, it is assumed that the hearing aids used with it conform to all relevant parts of IEC Click to learn more.
