Abstract: A method for acquiring the surrounding environment of a motor vehicle. The motor vehicle has at least one ultrasound sensor. The ultrasound sensor includes an ultrasound transducer for sending, the ultrasound sensor receiving acoustic environmental signals, in particular audible environmental signals, in that the ultrasound sensor is controlled in its evaluation in such a way that sound waves having frequencies below a resonant frequency of the ultrasound transducer, in particular audible sound waves, of an environmental signal are acquired and evaluated. Environmental signals are understood as acoustic signals that are not produced by the ultrasound transducer itself, but rather by an external sound source that in particular differs from the motor vehicle. This can be for example the siren of a rescue vehicle or emergency vehicle, or the horn of some other motor vehicle.
