QRD Diffuser Well Depth Calculator Welcome. This script will calculate the well depths of a QRD (Quadratic Residue Diffuser) given a specified well width and a maximum well depth. The width and max depth should be specified in inches, with or without decimal fractions (ie 9 or 8.5 for example). This can be used as a guide for building a diffuser.
QRDude saves you having to get out the calculator to work out the well depth for your diffuser. It will design standard and advanced 1D panels, plus 2D panels, in normal and inverse variations. QRDude in Advanced Mode demonstrating well shifting, manual well width, half-width end wells, and imperial units.

In small rooms, it is often desirable to control interfering reflections and provide an ambient sound …
Calculate here QRD (estimated Size) … The actual depths of the wells are dependent on the design wavelength of the diffuser . In order to calculate these depths, Schroeder suggests the function dn = sn * (DF / 2 p) where dn is the depth of well n and DF is the design wavelength. The widths of these wells w should be constant and small compared …
QRD Diffuser Well Depth Calculator, Acoustic Diffusers – Diffuser Calculator, Acoustic Diffusers – Diffuser Calculator, QRD N7. Usable range: 381 – 2858 Hz. Open the app; Choose the QRD; Set design frequency to 763 hz; Set „number of wells“ to 7; Set the height to 117 cm and use fins with thickness: 0.5 cm; Click the „Calculate“ button; You have approximatly the same diffuser as the one made by GIK.
7/6/2010 · QRDude is a calculator for designing QRD diffusers. In standard mode, it provides similar functionality to existing calculators , although it adds a few features, such as support for inverse panels. In advanced mode, it supports the design of panels that have had their wells shifted downwards…
Schroeder diffuser calculations . Estimated cells sizes are given in centimeters. Insert diffuser order, project frequency and temperature meanings. The program will automatically calculate cells’ width and depth, and also the bounds of effective frequencies diapason.
