Bác nào có chương trình "Quadratic residue diffuser calculator" thì cho em xin. Rất cảm ơn. ... Xin giúp đỡ thiết kế tán âm QRD mẫu 2D - N29
2D-QRD - Sound Treatment. A common method of defining the wells' depth is to use the residue value of a division from the square of the coordinate and a prime figure. Unlike as with common QR-diffusers both dimensions are covered which leads to more a scattering behavior than known from 1D-QRD-Designs.
Calculate here QRD ( estimated frequency ) The Quadratic Residue Diffuser Schroeder presented methods of designing concert hall ceilings that could avoid direct reflections into the audience. In 1975, he provided a way of designing highly diffusing surfaces based on binary maximum-length sequences, and showed that these periodic sequences have ...
Feb 21, 2017 · The studio I used to mix at in London had an RPG Diffractal (Fractal QRD Diffuser), which offers the best of everything. It has deep gutters to break up lower frequencies and within each gutter even smaller gutters to break up the mid and higher frequencies.
C. Simulated diffuser shape A well-known and widely investigated shape has been chosen (Figure 1) for the purposes of calculation validation – the QRD or Schroeder diffuser shape. The motivation behind this choice is that this is essentially a two dimensional shape, i.e. scatters the sound in a hemi cylinder way.
