Description
This paper describes high-realistic acoustic sound field reproduction using a parametric array loudspeaker. We focus on hybrid amplitude modulation with SSB and DSB to obtain higher power and sound quality: distance as a demodulation criterion for estimating the maximum sound pressure; an audible sound spot in the minimum zone for reproducing an acoustic sound field in the minimum zone: near-field sound propagation based on individual delay filtering for carriers and multiple sideband waves: and flexible parametric array loudspeakers for controlling audio spots.
