METHOD OF REALIZING INDEPENDENT SOUND FIELD IN CONSIDERATION OF SPEAKER SOUND CHARACTERISTICS AND SYSTEM THEREOF

摘要

The present invention relates to a method of realizing an independent sound field and a system thereof. According to the present invention, the method of realizing an independent sound field comprises the following steps of: extracting characteristics of a plurality of speakers arranged in a space; extracting a sound transfer function between the speakers arranged in the space and a listening position; extracting a correction function according to characteristics of an individual speaker; extracting a correction sound transfer function according to the extracted correction function; configuring a price function for realizing an independent sound field by using the extracted sound transfer function and deriving an optimal value; and calculating a control filter according to the derived optimal value. Therefore, it is possible to reduce a numerical error when a filter is calculated and reduce generation of noise accordingly by calculating a control filter reflecting characteristics of an individual speaker, and to realize an effective independent sound field only with directionality without a control filter in a frequency band that allows sound separation between seats depending on the distance.;COPYRIGHT KIPO 2020
