A sound system and method for modeling a sound field generated by a sound source and creating a sound event based on the modeled sound field is disclosed. The system and method captures a sound field over an enclosing surface, models the sound field and enables reproduction of the modeled sound fiel
A sound system and method for modeling a sound field generated by a sound source and creating a sound event based on the modeled sound field is disclosed. The system and method captures a sound field over an enclosing surface, models the sound field and enables reproduction of the modeled sound field. Explosion type acoustical radiation may be used. Further, the reproduced sound field may be modeled and compared to the original sound field model.

The system of claim 1, wherein the lobe in which the sounds represented by the first audio signal emanated from the sound source corresponds to the lobe in which sounds generated by the first set of one or more speakers emanate from the plurality of reproduction modules, and wherein the lobe in which sounds represented by the second audio signal emanated from the sound source corresponds to the lobe in which sounds generated by the first set of one more speakers emanate from the plurality of reproduction modules. 3. The system of claim 2, wherein the processor is further configured to adjust one or more parameters of individual ones of the audio signals such that the directivity pattern of the sound field produced by the plurality of reproduction modules has a rotational orientation with respect to the plurality of reproduction modules that is different from a rotational orientation of the directivity of the obtained sound field with respect to the sound source from which it emanated. 4. The system of claim 1, wherein the obtained sound field emanated outwardly from the sound source with an initial amplitude, and wherein the processor is configured to drive the plurality of reproduction modules such that the sound field generated by the plurality of reproduction modules has an amplitude with a configurable relationship to the initial amplitude of the obtained sound field. 5. The system of claim 1, wherein the processor is further configured to obtain the plurality of audio signals from an electronically readable medium. 6. The system of claim 1, wherein the processor is in operable communication with a sound capture system configured to capture the sound event as it emanates from the sound source, and wherein the processor obtains the plurality of audio signals from sound capture system. 7. The system of claim 1, wherein the plurality of reproduction modules further comprises a plurality of amplifiers that are controllable by the processor to selectively amplify the plurality of audio signals prior to the provision of the plurality of audio signals to the speakers of the plurality of reproduction modules. 8. A method of producing a sound field, the method comprising: obtaining a plurality of separate audio signals that represent a captured sound field that emanated outwardly from a sound source with a directivity pattern, wherein the plurality of separate audio signals comprise: a first audio signal representing sounds in the sound field that emanated from the sound source in a lobe; and a second audio signal representing sounds in the sound field that emanated from the sound source in a lobe that is different from the lobe in which the sounds represented by the first audio signal emanated from the sound source; and driving a plurality of reproduction modules to generate a sound field that corresponds to the obtained sound field such that the sounds associated with the sound field generated by the plurality of reproduction modules emanates outwardly from the plurality of reproduction modules with a directivity pattern that represents the directivity pattern of the obtained sound field, wherein the plurality of reproduction modules comprises: a first set of one or more speakers configured to receive one or more audio signals, and to generate sounds based on the received one or more audio signals, the sounds generated by the first set of one or more speakers emanating from the plurality of reproduction modules in a lobe; and a second set of one or more speakers that are separate from the first set of one or more speakers, the second set of one or more speakers being configured to receive one or more audio signals, and to generate sounds based on the received one or more audio signals, the sounds generated by the second set of one or more speakers emanating from the plurality of reproduction modules in a lobe that is different from the lobe in which sounds generated by the first set of one or more speakers emanate; and wherein driving the plurality of reproduction modules comprises providing the first audio signal to the first set of one or more speakers and providing the second audio signal to the second set of one or more speakers. obtaining a plurality of obtained sound fields, wherein each of the obtained sound fields emanate outwardly from one or more sound sources with a source directivity pattern; and driving a plurality of reproduction modules to emanate a plurality of emitted sound fields outwardly therefrom, wherein each of the individual reproduction modules are driven to produce an emitted sound field that corresponds to one of the obtained sound fields such that a directivity pattern of a given emitted sound field at or near the individual reproduction module from which it emanates is representative of the source directivity pattern of the corresponding obtained sound field. 9.
