Beschreibung
Zusammenfassung:	A device (1) for airborne sound acoustic sensing of the surroundings of a vehicle, the device (1), comprising at least one microphone (2), which is integrated in a housing (3) which, in the region of the microphone (2), has at least one opening (4) for the entry of sound waves. According to the invention, in the region of the opening (4) and at a distance from the microphone (2) there is arranged at least one film or membrane (5) which, together with the microphone (2) and the housing (3), delimits an ante-volume (6), the cross-sectional area of which increases from inside to outside in relation to the housing (3), so that a cross sectional area (A) of the ante-volume (6) adjacent to the film or membrane (5) is greater than a cross sectional area (B) of the ante-volume (6) adjacent to the microphone (2).
