Qrd Diffuser Panel - Chinaprice: 40.00 Dollar US$
The function of the diffuser is to equalize the sound pressure level everywhere in the space, so that the sound in each space is as the same as possible.
It is an acoustic product, and its design is based on the acoustic foundation, not personal preference.
Aiming at the limitation of MLS diffuser, Schroeder proposed qrd diffuser panel based on the secondary residual sequence.
The surface of the qrd diffuser panel (secondary remainder diffuser) is arranged by many grooves with the same width and different depths.
The groove width and groove depth of the QRD diffuser are determined according to the following method: the groove width considers the wavelength 1/2 of the high diffusion frequency of zzui; the groove depth considers the wavelength 1/2 of the low diffusion frequency of zzui.
After determining the depth of the groove, the second residual sequence is used as a factor to determine the depth of each groove.
Formula: Sn=n²modp (integer from 0 to infinity, meaning of mod remainder).
Here we only need to understand that p is a prime number (can only be divided by 1 and itself).
For example, when p=7, one cycle of the sequence is: 0, 1, 4, 2, 2, 4, 1 - According to the groove depth and sequence, the depth of each groove can be determined.
For example, if the low diffusion frequency is selected as 500 Hz and the wavelength is 68 cm, the depth of the large groove of zzui is 34 cm, and the depth of each groove in a period is 0, 8.5 cm, 34 cm, 17 cm, 17 cm, 34 cm, 8.5 cm.
