  • Communication device with dynamic echo suppression and background noise estimation
    Patent number: 5771440
    Abstract: Echo suppression is accomplished by comparing the ratio of the microphone (101) and speaker (121) energies to a dynamic threshold that varies with the background noise (310) at a second communication device (130), and transmitting locally generated noise when the potential for echo exists. The use of the dynamic threshold provides for echo suppression with significantly better doubletalk performance.
