The quick answer
Treat first reflection points, then corners, then the ceiling above the desk. Aim for 30 to 40 per cent coverage rising to 70 with diffusion, never full. If your problem is neighbours rather than recordings, that is isolation and needs mass, not panels. Sort out which of the two you actually have before spending anything.
A home studio has two separate acoustic requirements and they are routinely confused. Treatment controls how the room sounds to your microphones and monitors. Isolation controls what crosses the walls in either direction. Foam does the first and nothing for the second, which is why so many home studios end up well treated and still unusable after 9pm.
01 /Decide which problem you have
| Symptom | Problem | What it needs |
|---|---|---|
| Recordings sound boxy or hollow | Reflections | Absorption at reflection points |
| Bass sounds different in each chair | Low frequency build-up | Corner bass traps |
| Mixes do not translate elsewhere | Untreated monitoring position | Treatment plus speaker placement |
| Traffic or family audible on takes | Isolation | Mass, not foam |
| Neighbours complain at night | Isolation | Mass, not foam |
02 /Treatment, in priority order
- First reflection points. Sit at the desk and have someone slide a mirror along each side wall at ear height. Wherever you can see a monitor in the mirror, a panel belongs. Do the same for the ceiling above the midpoint between you and the speakers.
- All four corners. Bass collects where surfaces meet. Four bass traps at floor level is the minimum, eight across floor and mid height is where most home rooms settle.
- Ceiling above the desk. A cloud here stops the first ceiling reflection arriving just behind the direct sound, which is what blurs detail.
- Rear wall. Absorption if the room is small, diffusion if you have depth behind you. Diffusion keeps the room from going lifeless.
03 /Layout matters as much as panels
- Face the short wall. Set up along the length of the room so reflections have further to travel before returning.
- Symmetry. Equal distance from each side wall. An off-centre position gives you a different reflection on each ear and no amount of treatment fixes it.
- Pull monitors off the wall. Speakers hard against a surface reinforce bass unevenly. A gap behind them costs nothing and changes a great deal.
- Avoid corners for the desk. The worst place to sit is where bass collects most.
04 /If you need isolation too
If the real problem is noise crossing the wall, treatment will not touch it. Isolation means mass: SoundBlanket MLV at 4mm, rated STC 34, as the barrier, BassBloc over it to damp resonance, then a finish layer. Seal the door with a bottom seal and perimeter tape before anything else, because a door gap will out-leak the whole wall.
Treatment goes on top of that build-up as the finish. The two jobs stack, they do not substitute.

05 /Frequently asked questions
How much treatment does a home studio need?
Start at 30 to 40 per cent of wall area, concentrated at first reflection points and corners. A studio may reach 70 per cent when combined with diffusion. Full coverage produces a dead room that is uncomfortable to work in and gives mixes that translate poorly.
Will acoustic treatment stop my neighbours hearing me?
No. That is isolation and it needs mass. Foam and panels control reflections inside the room but block almost nothing crossing a wall. For isolation you need MLV as a barrier, BassBloc over it, a finish layer, and a properly sealed door.
Where do the first panels go?
At first reflection points. Sit at the desk and have someone slide a mirror along the side wall at ear height. Wherever a monitor appears in the mirror, that is where a panel belongs. Repeat for the ceiling above the midpoint between you and the speakers.
Does room layout matter as much as treatment?
Often more. Sit symmetrically between the side walls, face along the length of the room, pull the monitors away from the wall behind them, and keep the desk out of a corner. These cost nothing and no amount of panelling compensates for getting them wrong.
