Pertains 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 698 MHz to 6 GHz.
