Abstract: A method for localizing at least one sound source using at least two ultrasonic sensor arrays, which each have at least two transducer elements for receiving sound waves. The transducer elements receive sound waves and generate electrical signals representing the received sound waves. At least one phase offset between the at least two electrical signals is ascertained. The sound source is located by triangulation on the basis of the ascertained phase offsets between the electrical signals and a distance a between the ultrasonic sensor arrays. A control device, a computer program, and a machine-readable storage medium, are also described.
