Diffusors

A diffusor provides diffuse reflection of the sound radiat-
ed against it. Diffusers can be very useful in situations
where reflections are disturbing the sound image and it
is not advisory to add further absorption. So in order to
reduce flutter echoes, comb filtering etc., special ele-
ments can be placed on the “disturbing” surface. These
elements must have dimensions comparable to the fre-
quencies at which diffusion is wanted.

Absorption or diffusion?

Fig. 64: Absorption versus diffusion

A special technique developed by Manfred Schroed-
er is very capable in making a smooth and controlled
diffusion. These “Schroeder Diffusors” are available as
prefab modules.
