A microphone arrangement includes a database and multiple pressure gradient transducers having a diaphragm, a first sound inlet opening, and a second sound inlet opening. A directional characteristic of each of the pressure gradient transducers have a direction of maximum sensitivity in main directions. The main directions of the pressure gradient transducers are inclined. A pressure transducer has an acoustic center lying within an imaginary sphere with multiple acoustic centers of the pressure gradient transducer. The imaginary sphere has a radius corresponding to about double the largest dimension of the diaphragms of the pressure gradient transducers and the pressure transducer. The database retains representative signals of the multiple pressure gradient transducers and the pressure transducer. A processor accesses the database to determine a position of a sound source.
