The invention relates to an ultra sonic sensor arrangement (2) for a motor vehicle (1), comprising a lining part (3), in particular a bumper, a radiator grill (4), and at least one first and one second ultrasonic sensor (5, 6) respectively comprising a membrane (11) for emitting and/or capturing ultrasonic signals. The first ultrasonic sensor (5) with the membrane (11) is arranged on a rear side of the lining part (3) so that the membrane (11) of the first ultrasonic sensor (5) is formed through the lining part (3) for emitting and/or capturing the ultrasonic signals, and the second ultrasonic sensor (6) is arranged on the radiator grill (4). The second ultrasonic sensor (6) is detuned by detuning means (7, 9) and the emission and/or capturing behaviour is adapted to the emission and/or capturing behaviour of the frist ultrasonic sensor (5).
