Position determination of sound sources

A method of synthesizing one or more microphone signals from a microphone arrangement comprising:

• providing a plurality of pressure gradient transducers, each having a diaphragm, a first sound inlet opening leading to the front of the diaphragm, and a second sound inlet opening leading to the back of the diaphragm;
• providing a directional characteristic of each of the plurality of pressure gradient transducer having a direction of maximum sensitivity in a plurality of main directions, and in which the plurality of main directions of the plurality of pressure gradient transducers are inclined relative to each other,
• providing a pressure transducer having an acoustic center lying within an imaginary sphere with a plurality of acoustic centers of the pressure gradient transducers, the imaginary sphere having a radius corresponding to double the largest dimension of the diaphragm of the plurality of pressure gradient transducer or the pressure transducer;
• providing a database that retains representative signals of a plurality of outputs of the pressure gradient transducers and the pressure transducer;
• providing a processor that accessed the database to determine a position of a sound transmitting source;
• and
• comparing outputs of the plurality of pressure gradient transducer and the pressure transducer;
• with a plurality of stored signals retained in the database, each stored signal corresponding to one of the outputs of the plurality of pressure gradient transducer and the pressure transducer and being coded with a position information in relation to a microphone arrangement;
• where the determination of the position of the sound source depends on a similarity between the actual signal and the stored signal.
