Abstract:
1. A conference terminal for a digital voice conference system, comprising: a first sound transducer, which is implemented to generate a microphone signal from an acoustic signal; a second sound transducer, which is implemented to generate an acoustic signal from a loudspeaker signal; a connector, which is implemented to enable a connection between the conference terminal and a conference central unit for receiving a composite conference signal from the conference central unit; and a suppressor for echo suppression, which is implemented to combine the microphone signal or a signal derived therefrom with the 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, or to combine the microphone signal or a signal derived therefrom with the composite conference signal, in a talk operation wherein the microphone signal is transmitted to the conference central unit, such that a loudspeaker signal results, in which the acoustic signal, on which the microphone signal is based, is reduced; and a threshold decider, which is implemented to deactivate the suppressor for echo suppression when the microphone signal is smaller than a predetermined threshold.
