When to use absorption, and when diffusion?

panel placement & reflections

Amongst all the voodoo in studio acoustics, I don’t think there’s anything more voodoo than diffusion.

And I don’t mean like with sound crystals. Diffusion does absolutely work.

But amongst the stuff that is part of the standard acoustics toolkit, it’s definitely the thing with the most myth surrounding it.

To the point where there are people out there who will literally answer with “diffusion!” when you ask them about the one thing you should think about when treating your studio.


If I may, I would like to add my mustard to this discussion, as we say in German.

If you’re working out of a home studio, when should you think about using absorption, and when diffusion for your acoustic treatment?

Let me show you.
