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.

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.

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.

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.
