Diffusion is an important part of the sound field environment; numerous calculations including Sabine formula or Elaine formula are completed on the basis of complete diffusion of sound field, thus an environment of insufficient sound field diffusion is very likely to affect the accuracy of the acoustic calculation formula. Therefore, when we shape the sound field environment, taking the even diffusion of sound field as a crucial architectural acoustics project is advantageous to the purity and the improvement of sound quality.
The theory of sound field diffusion is derived from quadratic remainder diffusion theory published by Manf red R. Schroeder, the German physicist and acoustic expert in 1975. The diffusion of the sound wave studied by him is of great help to listen for the human ear. "Quadratic" in quadratic remainder diffusion theory refers to square, and the remainder refers to the remainder remained by after the natural number divided by the number of prime number (number cannot be divided except 1 and itself). Because it enables more even diffusion of sound waves, quadratic remainder diffuser plate is positive in sound quality. In addition to use in the ceiling, the more "diffusion" materials used in places such as wall space on both sides, rear wall space of speaker and rear wall space at listening location, etc. enable the greater sense of scale and broadness of spacious music venues, extending natural, harmonious and elegant high-frequency performance, and details in the music performance can also be increased greatly, and some of the weak dynamic changes difficult to be detected at ordinary times can be clearly shown.
