11、troduction This introduction is not a part of ANSI C63.19-2006, American National Standard Methods of Measurement of Compatibility between Wireless Communications Devices and Hearing Aids. In the fall of 1995 the Federal Communications Commission (FCC) initiated a Steering Committee to initiate a su
12、mmit on Hearing Aid Compatibility and Accessibility to Digital Wireless Telecommunications. The goal of the summit was to formalize and continue discussions among the three key affected interests in this issue: organizations representing people with hearing loss, hearing aid manufacturers, and the d
13、igital wireless telephone industry. The ultimate purpose of the summit was to find a resolution of the interference problem that was acceptable to the industries involved. A summit meeting was held on January 34, 1996, in Washington, DC. At this summit meeting three working groups were formed to pur
14、sue issue resolution. Subsequently, the Long-Term Solutions User and Bystander Interference Group reached a consensus that a standards project was needed to document the consensus definition of and method of measurement for Hearing Aid Compatibility and Accessibility to Wireless Telecommunications.
15、Subsequently ANSI C63 was petitioned to undertake the joint standards projects documenting the methods of measurement and defining the limits for Hearing Aid Compatibility and Accessibility to Wireless Telecommunications. At its April 1996 meeting, ANSI C63 established a task group under its subcomm
16、ittee on medical devices (SC 8). The charge to this task group (TC C63.19) was to develop such standards in cooperation with representatives of organizations representing people with hearing loss, hearing aid manufacturers, the digital wireless telephone industry, and other interested parties. The 2
17、001 version of this document was the result of that committees efforts. The FCC adopted this standard to provide the technical requirements for its Report and Order establishing mandatory requirements for wireless hearing aid compatibility on July 10, 2003.a Following the adoption by the FCC and for
18、 several reasons, including technical changes in wireless communications devices and hearing aids and new understanding coming from experience gained in working with the 2001 version of this standard, a new revision effort was started. The result of this revision effort culminated in the production
19、of this version of the standard.

American National Standard Methods of Measurement of Compatibility between Wireless Communications Devices and Hearing Aids 1. 1.1 1.2 Overview Scope This standard applies to both
44、 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)
45、 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 frequenc
46、y bands. Future versions may add tests 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-canal (
47、CIC) types. Test methods are provided for hearing aids operating in acoustic (microphone input) mode or in T-Coil input mode. 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 Purpose The purpose of thi
48、s 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 1 Fo
