    REVISION HISTORY

    Abstract - (Show below) - (Hide below)

    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 wireless communications devices, 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.
