Abstract

An apparatus for localizing a sound source includes at least two rotatably arranged microphones, a drive formed to set the microphones into rotation, and an evaluator. The evaluator is formed to receive microphone signals of the at least two microphones, while the at least two microphones are moving, and to obtain information on a direction from which sound arrives from the sound source or information on a position of the sound source, using the microphone signals obtained during the movement of the microphones.
