Reception sound signals occur that provide an individual pattern of the reproduced and transmitted Q electrical audio signals. The method includes processing the Q electrical audio signals to provide K processed electrical audio signals and converting the K processed electrical audio signals into corresponding K acoustic audio signals with K groups of loudspeakers that are arranged at positions separate from each other and within or adjacent to the N sound zones. The method further includes monitoring a position of a listener's head relative to a reference listening position. Each of the K acoustic audio signals is transferred according to a transfer matrix from each of the K groups of loudspeakers to each of the N sound zones to contribute to the corresponding reception sound signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sound system for establishing a sound zone","description":"A system and method for acoustically reproducing Q electrical audio signals and establishing N sound zones is provided.
