Patent ID: 8472639

Claim:
A microphone arrangement comprising: a plurality of pressure gradient transducers each having an acoustic center, a first sound inlet opening leading to a front of a diaphragm, and a second sound inlet opening leading to a back of the diaphragm; a directional characteristic of each of the plurality of pressure gradient transducers comprising an omni portion and a figure-eight portion, the plurality of pressure gradient transducers each having a direction of maximum sensitivity in a main direction, each main direction of the plurality of pressure gradient transducers are inclined relative to each other; and a pressure transducer having a diaphragm and an acoustic center, the acoustic center lying within an imaginary sphere with each of the acoustic centers of the plurality of pressure gradient transducers, the imaginary sphere having a radius corresponding to double the largest dimension of the diaphragm of the pressure transducer or the plurality of pressure gradient transducers.
