Bronaugh  aAtlanta :bIEEE,c27 May 2011  a140 p.  aAbstract:
Available in PDF only. Uniform methods of measurement for compatibility between hearing aids and wireless communications devices are set forth.
Scope:
This standard applies to both wireless communications devices (WDs) and hearing aids. It sets forth uniform methods of measurement and parametric requirements for the electromagnetic and operational compatibility and accessibility of hearing aids used with WDs, including cordless, cellular, personal communications service (PCS) phones, and voice over internet protocol (VoIP) devices, operating in the range of 800 MHz to 3 GHz. However, this version is focused on existing services, which are in common use. Accordingly, in this version tests are provided for services in the 800 MHz to 950 MHz and 1.6 GHz to 2.5 GHz frequency bands. Future versions may add test...
Purpose:
The purpose of this standard is to establish categories for hearing aids and for WDs that can indicate to healthcare practitioners and hearing aid users which hearing aids are compatible with which WDs and to provide tests that can be used to assess the electromagnetic characteristics of hearing aids and WDs and assign them to these categories. The various parameters required, in order to demonstrate compatibility and accessibility are measured. The design of the standard is such that when a hearing aid and WD achieve one of the categories specified, as measured by the methodology of this standard, the indicated performance is realized.  aAmerican National Standard  aC63.19  aElectromagnetic compatibility  aHearing aid  aHearing aid compatibility (HAC)  aMeasurement methods  aOperational compatibility  aWireless communications device
