Abstract
The present disclosure relates to a positioning method and apparatus in a three-dimensional space of reverberation. The method includes the following steps: constructing a three-dimensional space frame surrounding a point sound source and a sound receiver, and acquiring barycentric coordinates of the three-dimensional space frame; establishing an X-Y coordinate system by using the barycentric coordinates as the origin; determining a vector from the sound receiver to the barycentric coordinates and a facing angle between the sound receiver and the barycentric coordinates according to the established X-Y coordinate system; and obtaining reverberation intensity through calculation according to the vector from the sound receiver to the barycentric coordinates and the facing angle between the sound receiver and the barycentric coordinates, and using the reverberation intensity as a control parameter.
