  • CONFERENCE TERMINAL WITH ECHO REDUCTION FOR A VOICE CONFERENCE SYSTEM
    Publication number: 20070189507
    Abstract: A conference terminal for a digital voice conference system comprises a first sound transducer means, which is implemented to generate a microphone signal from an acoustic signal, a second sound transducer means, which is implemented to generate an acoustic signal from a loudspeaker signal, a connecting means, which is implemented to enable a connection between conference terminal and a conference central unit, to receive a composite conference signal from the conference central unit, and a means for echo suppression, which is implemented to combine the microphone signal or a signal derived therefrom in a noise suppression means with a composite conference signal in a listening operation of the conference terminal, such that a loudspeaker signal results, in which the acoustic signal, on which the microphone signal is based, is reduced.
