 Technology: diffusion is an important component of a sound field environment, including many such as the Sabine formula or Erin formula calculation are calculated on the basis of complete diffusion of the sound field, so a sound field diffusion inadequate environment, is likely to affect the acoustic calculation The accuracy of the formula. To this end, in shaping the sound field environment, making the proliferation of uniform sound field as an important project of sound construction, sound quality is pure and improve. Sound field diffusion theory comes from a German physicist, acoustics expert quadratic residue diffusion theory. Come up with the spread of the sound waves of great help to the human ear to listen. Quadratic residue diffusion theory of "secondary" refers to the secondary side, the remainder is the remainder left after a natural number divided by the prime number (except 1 and itself, can not be divisible number). Can make the sound wave diffusion is more uniform, quadratic residue diffuser plate sound for sound positive. Use outside of the ceiling, both sides of the wall, after wall speakers to listen to on the rear wall of the location, etc. use the "spread" more material, the more you can feel the size and breadth of the music venues sense of space large extension of the natural pine melt flowing high-frequency performance, the details in the music performance can be greatly increased, and usually difficult to perceive some weak dynamic changes can be clearly shown. 
 Scope of opera, music to listen to the audition room, studio, recording studio, listening room, the quality requirements of the higher places.
