Room Treatment
Controlling reflections with absorption and diffusion so the listening position tells the truth
Related
Room treatment changes how a room responds acoustically, using absorption, diffusion and low-frequency control so the listening position hears closer to the recording itself. It addresses reflections and resonances inside the room, not sound isolation.
The order is usually speakers and listening position first, then the first reflection points, rear wall and corners: absorption for early reflections, diffusion on the rear wall to keep some space, bass traps in corners. Symmetry matters more than piling up material, and measurement plus listening should confirm the result.
The usual mistake is covering every surface with foam. Too much absorption dries the sound and can make bass seem stronger; too little leaves reverb and comb filtering in the way of judgement.
