Method for reconstructing an acoustic field

[0043] figure 1 A schematic block diagram of a system for reconstructing a sound field is shown. The system comprises a set of acoustic receivers 108 and an analysis unit 103 connected to the acoustic receivers.

[0044] In the following, the acoustic receiver 108 will also be referred to as a transducer. However, it should be understood that the acoustic receiver may be a microphone, hydrophone, or any other suitable device for measuring an acoustic characteristic such as sound pressure, sound pressure gradient, particle velocity, and / or other linear quantities, or combinations thereof . exist figure 1 In an embodiment of the present invention, the transducers 108 are implemented as an array 102 of transducers, wherein the transducers 108 are arranged in a regular grid (eg, a 1-dimensional grid, a 2-dimensional grid, or a 3-dimensional grid). While the arrangement in a regular grid allows for efficient numerical implementation, other geometries may be used. In some embod...
