Beschreibung
Zusammenfassung:	A transportation vehicle provides a workspace in a passenger cabin to support a teleconference with a remote party. External sensors are configured to scan the exterior of the vehicle and detect a pedestrian. A sound exciter is configured to generate a masking noise directed to the exterior. A control circuit which enhances privacy of the teleconference is configured to A) detect the audio content of the teleconference being present in the interior of the vehicle, B) quantify an interior sound level of the audio content, C) estimate a discernibility of the audio content at an external location corresponding to the detected pedestrian, and D) activate the sound exciter such that the masking noise is adapted to mask the audio content at the external location.
