Place sound panels on the walls where sound bounces from the speakers to your ears: the side walls beside your listening spot, the wall behind the speakers, and the ceiling above. Space the panels across the surface instead of covering it edge to edge, then listen and move panels until the echo drops.
Start with the walls beside your listening spot
Sit where you listen and look at the side walls: the spots between you and the speakers are where sound bounces back to your ears. Put panels on those spots on both side walls, at the height of your ears when seated. These reflection points matter more than covering a whole wall.
Cover the wall behind the speakers
Put panels on the wall behind the speakers as well, since sound also bounces off the wall behind them and back into the room. Cover the area directly behind each speaker and the space between them. This keeps sound that bounces off that wall from coming back toward you after it leaves the speakers.
Space the panels instead of covering the wall
Leave gaps between panels instead of covering a wall edge to edge. Spaced panels still absorb the echo at the reflection points, and you use fewer panels to cover the same wall. Spread the panels across the surface in a pattern that covers the reflection points, with bare wall between them.
Treat the ceiling and the corners
Put panels on the ceiling above your listening spot, since sound bounces off the ceiling as well as the walls. Wedge panels also work as bass traps in the corners, where low sound gathers. Mount ceiling panels with construction adhesive or double-sided tape, and press each panel flat so it holds.
Listen and move panels until the echo drops
Clap your hands in the listening spot and listen for the echo that follows. If the echo is still there, add panels at the bare spots on the side walls or move panels from places that made no difference. Keep listening after each change until the echo drops and voices in the room are easy to follow.

Frequently asked questions
How many sound panels does a room need?
It depends on the size of the room and how much echo you hear. Start with the reflection points on the side walls and behind the speakers, then add panels until the echo drops and the room sounds right to you.
Do sound panels stop noise from outside?
No. Foam panels absorb echo and reverberation inside the room; they do not stop noise coming through the walls. Outside sounds still come through, so panels help the sound inside the room rather than shutting the room off.
Can I put sound panels on the ceiling?
Yes. Acoustic foam panels install on walls and ceilings with construction adhesive or double-sided tape. Press each panel flat against the ceiling and hold it until the adhesive grips.
Do I need adhesive to mount sound panels?
Some packs include adhesive tape or pads, while others do not, so check what comes in the pack. Construction adhesive or double-sided tape mounts the panels without drilling, and the pads peel off without leaving residue.
