polyfoam diffusion plate, Guangdong diffuser sound-absorbing panels.
Diffusion is an important part of acoustic environment, including many such as Sabine formula or Erin formula are in sound completely diffusion on the basis of calculation, so a sound field diffusion inadequate environment, are likely to affect the accuracy of the acoustic calculation formula. To this end, we in shaping the sound environment, to make sound field diffusion uniform as an important architectural acoustic project, is beneficial to the quality of pure and improve.
Sound field diffusion theory comes from the German physicist, acoustics expert Manf red R.Schroeder published in 1975 of two the remainder diffusion theory. He developed a sound diffusion to the human ear listening are of great help. Two remainder diffusion theory in the " two" refers to the two party, the remainder is naturally divided by the number of prime numbers (except 1and itself, not divisible number ) have left after the remainder. Acoustic wave spread more evenly, two times the remainder diffusion plate for sound quality is positive help.
Compared with smooth reflective surface, the diffusion plate can effectively avoid the sound focusing. When sound waves through the smooth wall reflection, all of the energy will be along the same direction reflection, reflection direction is fixed, depending on the location of the sound source. When the sound waves through the remainder of two time diffusion plate surface reflection, reflection energy would be scattered in different directions, and has a different phase difference.
The homogeneous energy irregular reflection sound will make the subjective produces a sense of space, at the same time used in high frequency diffusion will increase the voice of" bright". The reflection direction similar to a semicircle, acoustic energy average diffusion.
polyfoam diffusion plate can be used not only to break up the sound energy, to prevent echo and standing wave effect, at the same time can improve the sound of bright, in the early reflection path add two times the remainder diffuser reflection 2K near high frequency can increase the brightness, and sound absorbing materials are matched with each other, can obviously improve the quality improvement.
