Methods of Measurement of Compatibility between Wireless Communication Devices and Hearing Aids
|Publication Date:||1 January 2006|
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 for other frequency bands, as they come into more common use.
This standard is intended to apply to all types of hearing aids with acoustic output, including, as examples, behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), and completely-in-the-ca
The field levels called for in various places shall be maintained within the limits for radio frequency (RF) safety, set forth in ANSI C95.1-1999.1
