What is acoustic diffusion?
A5. A non-flat shape that has enough dimensional variation to scatter sound that strikes it. Acoustic diffusion can be in many forms, such as the more common pyramids and partial “barrel” shapes along with the more modern QRD (digital) shapes. The amount of dimensional variation determines the frequency response of the device. Although they can be useful, very large angular shapes and ceiling coffers are actually more reflectors than diffusion. A small amount of dimensional variation is limited to High-Frequency diffusion.
