(54) Device and method for generating a side tone


(57) The invention relates to a device and a method for generating a side tone (84), in particular for application in aviation and space technology. The device comprises a headset (50) with a microphone and earphones for the acquisition of an original signal (80) and for the reproduction of a side tone (84), a communication unit (43, 40) for connecting and controlling the headset (50), and a transmit/receive module (20). The device for generating the side tone (84) is characterised in that it furthermore comprises a comparator (60) which receives both the signal (81) that enters the transmit/receive module (20) and the signal (82) that is in fact being transmitted by the transmit/receive module (20), and in that it determines that the original signal (80) is actually being transmitted. In this case the comparator (60) instructs the communication unit (43, 40) to output the original signal (80) as a side tone (84) by way of the earphone of the headset (50).
