Calibrating Induction Loop Systems as Per IEC Standards
iex Your basket is empty. 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. Addition of Annexes G, H and I where more information is provided about practical considerations and methods of measurement.
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 justification to the 601118 was pretty straightforward.
Ampetronic: hearing loop performance standards IEC
Preview Abstract IEC You are commenting using your Facebook account. 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, noisy or uneven signal response.
We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. The following test report forms are related: 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 from the individualized settings of his or her hearing aid.
