Abstract
Tuning loudspeakers’ settings is indispensable for the best music reproduction. Therefore, we developed a high-resolution three-dimensional acoustic reproduction evaluation method using ambisonics. The method can analyze reproduction conditions in all directions from the listening position and visualize them in an easy-to-understand 3D figure. The method can analyze direct and indirect sound components separately. By evaluating acoustic reproduction using stereo loudspeakers, we confirmed that this method could visualize the slight deviation of the loudspeakers’ position and the direction of the reflected sound.
