SOUND SYSTEM FOR ESTABLISHING A SOUND ZONE

摘要

A system and method for acoustically reproducing Q electrical audio signals and establishing N sound zones is provided. 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.

1. A sound system for acoustically reproducing Q electrical audio signals and establishing N sound zones, in each of which reception sound signals occur that provide an individual pattern of the reproduced and transmitted Q electrical audio signals, the system comprising:
a signal processing arrangement that is configured to process the Q electrical audio signals to provide K processed electrical audio signals; K groups of loudspeakers that are arranged at positions separate from each other and within or adjacent to the N sound zones, each of the K groups of loudspeakers is configured to convert the K processed electrical audio signals into corresponding K acoustic audio signals; and a monitoring system configured to monitor a position of a listener's head relative to a reference listening position; wherein: 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 reception sound signals, processing of the Q electrical audio signals comprises filtering that is configured to compensate for the transfer matrix so that each of the reception sound signals corresponds to one of the Q electrical audio signals, and filter characteristics of the filtering are adjusted based on an identified listening position of the listener's head.
