摘要：
A digital audio system of an aircraft comprising one or more audio equipment (11) and one or more radio equipment (47) providing a reliable side tone to the operators. The audio equipment (11) and the radio equipment (47) have installed in the proximity, respectively, an audio-terminal (27) and a radio-terminal (45) connected to a digital network (15) including digital messages management units (37, 57) and digital signal processors (39, 59). The digital messages management unit (37) of the audio equipment (11) is provided with a computer program adapted to generate a side tone of an analog audio message issued by the microphone (21) of the audio equipment (11) and to activate/deactivate its sending to the headset (25) of the audio equipment (11) when the audio-terminal (27) receives from the radio-terminal (45) an activation/deactivation command for said side tone.
