Reproduction of a sound field in a target sound area

摘要

The method involves analytically determining a drive signal for electro-acoustic transducer corresponding to sound field which is to be reproduced in a target acoustic region below spatial aliasing frequency of sound. The drive signal is changed by spatial band-limiting, so that the sound is reproduced within a range of optimization with higher accuracy and the modified drive signal to the electro-acoustic transducer. An independent claim is included for apparatus for reproducing sound in target acoustic region.
