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 use of hearing loops idc 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.

The following test report forms are related: 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.

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

The justification to the committee was pretty straightforward. You may experience issues viewing this site in Internet Explorer 9, 10 uec This site uses cookies. ie

This third edition cancels and replaces the second edition published in Be sure it includes Bluetooth as well as Telecoil Wireless Technology. For more specific information regarding the loop standard see here and here.

Those loops allows users iecc sit anywhere in the seated area and hear the same level of quality and sound broadcast directly to the telecoils in their instruments. Methods for measuring the magnetic field strength are specified, and information is given on appropriate measuring equipment see Annex Binformation that should be provided to the operator and users of the system see Annex Cand other important considerations.

The standard also specifies the minimum frequency response requirements for acceptable intelligibility. Search all products by. The clarity and understanding is excellent in those loops. It is the IEC standard that specifies these qualities and without it there can be no guarantee.

Poorly installed loops add frustration and doubt: 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 This means that hearing loop users depends on proper installation of a hearing loop.

These problems are of no concern in loops that meet the IEC standard. Addition of Annexes Iwc, H and I where more information is provided about practical considerations and methods of ieec.
