Title: TELECOMMUNICATION DEVICE, TELECOMMUNICATION SYSTEM, METHOD FOR OPERATING A TELECOMMUNICATION DEVICE, AND COMPUTER PROGRAM
Abstract:
A telecommunication device comprises an audio signal transmission device which is designed to receive an audio signal and transmit same to another telecommunication device. The telecommunication device further comprises a signaling device which is designed to output a signal when the audio signal is required to be acoustically intelligible to third parties or constitute a disturbance for third parties. An additional telecommunication device comprises an audio signal receiving device, which is designed to receive an audio signal from another telecommunication device and acoustically output the audio signal, and a signaling device, which is designed to output a signal when the output audio signal is required to be acoustically intelligible to third parties or constitute a disturbance for third parties. The telecommunication devices can be connected together in a system. The invention likewise relates to corresponding operating methods and to a computer program.
