Abstract
A method for delivering an optimized acoustic signal to a targeted sound field includes determining a bright zone having a high acoustic energy sound delivery region and a dark zone having low acoustic energy sound delivery region. The system selects a finite impulse response (FIR) filter set associated with a plurality of loudspeakers, and generates, via the plurality of loudspeakers and based on the FIR filter set, an acoustic signal having a sound pressure due to the combined loudspeakers (p) at an observation point r in a sound field disposed in the bright zone. The acoustic signal is delivered such that the sound pressure due to the combined loudspeakers at the observation point is approximately equal to unity acoustic energy at the observation point when the sound pressure due to the combined loudspeakers is generated via a single loudspeaker of the plurality of loudspeakers, and the remaining loudspeakers of the plurality of loudspeakers are off.
