Abstract

The invention discloses a method and a system for enhancing the sound field effect of a loudspeaker group in a regular tetrahedron structure. The method comprises the steps of enlarging the loudspeaker group in the regular tetrahedron structure to obtain four loudspeaker placing points and four virtual loudspeaker placing points; distributing four channels of collected first-order Ambisonics signals to four loudspeakers and four virtual loudspeakers; distributing signals of four virtual loudspeakers to three loudspeakers which are closest to virtual loudspeakers on the premise that the sound particle speed direction and the sound pressure intensity at a symmetrical central position of the regular tetrahedron structure are not changed; and canceling virtual loudspeakers. By the aid of the method and the system, the quality of the sound field can be reconstructed on the condition that loudspeakers of the same number are used.

Description

Technical field

[0001] The invention belongs to the field of acoustics, and in particular relates to a method and system for enhancing the sound field effect of a speaker group with a regular tetrahedron structure. Background technique

[0002] The movie "Avatar" released in my country in January 2010 has a global box office of over 2.6 billion U.S. dollars, and China's box office has exceeded 1.3 billion, setting a new world box office record. The success of "Avatar" technically relies on the application of 3D technology. What appears to the cinema audience is a strong visual shock, successfully freed from the shackles of the two-dimensional world, and led people into a three-dimensional world full of vitality and image. The movie "Avatar" is a milestone in the advancement of film technology. Not only that, it also promotes the development of more related technologies and standards in film, recording, and broadcasting. In order to achieve a better audiovisual experience, a thr...
