Comparison of Cubic and Quadratic residue diffusers

In modern studio design diffusers are used to smooth the sound environment. Next the common diffusers using the QRD-Shape we showed also a different equation using the CRD-Shape.

Two Equations for Diffuser

The subsequent image shows a common QRD-Design. It is fully symmetrical and uses 6 of 11 possible values. This design should be appropriate for small diffusers used in the rear position of a sound studio to maintain symmetry.

The subsequent image shows a newly invented CRD-Design. It is not fully symmetrical but uses all 11 values. This design can be used at the side walls of a room. It should be doubled and mirrored when used at the rear.

Conclusion and Summary

 Cubic equations can be used to obtain an alternative kind of sound diffusers.
