Abstract
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.
Claims23
A system for producing a sound field, the system comprising:
- means for receiving N signals that correspond to a received sound field emanating outwardly from within a predetermined geometric surface, wherein each of the N signals indicates one or more parameters of the received sound field at a separate one of N predetermined locations on the predetermined geometric surface;
- M transducers, disposed at least partially within the predetermined geometric surface and oriented to emit sound outwardly through the geometric surface;
- means for driving the M transducers to emit an emitted sound field outwardly through the geometric surface such that one or more parameters of the emitted sound field at the N predetermined locations on the predetermined geometric surface correspond to the one or more parameters of the received sound field at the N predetermined locations on the predetermined geometric surface.
A method for producing a sound field, the method comprising:
- obtaining N signals that correspond to an obtained sound field emanating outwardly from within a predetermined geometric surface, wherein each of the N signals indicates one or more parameters of the obtained sound field at a separate one of N predetermined locations on the predetermined geometric surface;
- positioning M transducers at least partially within the predetermined geometric surface;
- orienting the M transducers to emit sound outwardly through the geometric surface;
- and
- driving the M transducers to emit an emitted sound field outwardly through the geometric surface such that one or more of parameters of the emitted sound field at the N predetermined locations on the predetermined geometric surface correspond to the one or more parameters of the obtained sound field at the N predetermined locations on the predetermined geometric surface.
