The invention discloses a coordinate definition method of a sound field space. A position with the same altitude as an ear of a mixer being carrying out monitoring at the center of a horizontal tangent plane of the sound field space is defined as an original point of a coordinate; an number axis that passes through the original point of the coordinate and is perpendicular to the horizontal tangent plane is defined as a Z axis, wherein the forward direction of the Z axis is arranged upwardly; two number axes that are perpendicular to each other and pass through the original point of the coordinate on the horizontal tangent plane are defined as an X axis and a Y axis respectively; a position coordinate of a sound object in the sound field space is defined as (x, y, z); an action region of the sound object is defined as (phi, theta, gamma), wherein the phi expresses an included angle between a projection of a connecting line between the sound object and the original line on an xoy plane and the x axis and the ra
