Diffusers
A combination of sound reflection and absorption. Diffusers convex shape, with reflective surfaces, diffuse sound within a zone. Absorbers are designed to adjust the harshness of a room.
The basic idea of a diffuser is to scatter the sound in a number of directions. Thus reducing the harsh reflections that might otherwise be a problem.
