Abstract
A motor vehicle includes an acoustic device configured to generate and capture acoustic waves, the acoustic device includes a vehicle part having a vibration region, and an actuator arranged thereon and configured to for excitation and detection of vibrations of the vehicle part in the vibration region, wherein the region is modified compared to an adjacent region of the vehicle part and has greater sensitivity to excitations in the frequency range of the acoustic wave.
