  • Patent number: 5883927
    Abstract: A digital wireless telecommunication device for reduced interference with hearing aids includes an assistive listening device detector. The assistive listening device detector identifies the presence of different types of assistive listening device signals. In response to such a signal, the assistive listening device detector generates a reduced interference demand signal. Reduced interference digital wireless telecommunication output signals are generated in response to the reduced interference demand signal. The reduced interference digital wireless telecommunication output signals are typically in the form of full rate transmitter output signals. A variety of techniques are disclosed to produce the full rate transmitter output signals. The reduced interference digital wireless telecommunication output signals minimize disruptions to hearing aids in the vicinity of the digital wireless telecommunication device.
