Abstract (en)
[origin: WO2020064831A1] The invention relates to an audio output system for a vehicle. The audio output system according to the invention has a volume adjustment apparatus for adjusting a volume of an audio signal, an audio input for an audio input signal of an audio source, a warning sound apparatus for providing a warning sound signal, an audio level measurement apparatus for measuring the audio level on the audio input and a control unit. The audio level measurement apparatus is designed to limit the maximum audio level of the audio input signal as a function of the adjusted volume to a predefined first threshold value. The control unit is designed to control an audio output signal based on the warning sound signal, the audio input signal and the adjusted volume and to output an acoustic or visual notification when the audio input signal present at the audio input has no audio level.
