Diffusors

Absorbers reduce sound reflections; diffusors scatter them. Absorbers create a 'dead' sound, while diffusors maintain some natural room characteristics.

A lower Q factor (closer to 1) provides more even scattering across a wider frequency range; higher Q factors are more effective at higher frequencies but can create focused reflections.

While possible, smaller rooms require careful consideration of diffusor size and placement to avoid unwanted focusing of sound. Larger, more complex designs are generally more effective.
