Place acoustic panels on the walls where sound bounces between the speakers and your ears, and on the wall behind the speakers. Start with the side walls at ear height, the wall behind you, and the ceiling above the listening spot. Add panels where claps and voices echo, and leave bare wall where the room still needs life.
Find the spots where sound bounces
Stand in your usual listening spot and clap once, then listen for the flutter echo that rings back from the bare walls. Have a friend slide a mirror along each side wall while you stay seated: where you see a speaker in the mirror, sound from that speaker hits the wall on its way to your ears. Mark those spots and treat them before you cover any other wall.
Cover the side walls at ear height
Put panels on the side walls at the mirror spots you marked, centered on the height of your ears while you sit in the listening spot. Space them evenly across the marked area rather than clustering them in one corner of the wall. Leave a gap of bare wall between groups of panels so the room keeps some of its natural liveliness.
Treat the wall behind the speakers
Mount panels on the wall directly behind the speakers to catch the sound that bounces off it before it comes back into the room. Cover the area behind each speaker and the space between them, keeping the panels at the same height as the speakers.
Add panels to the wall behind you
Put panels on the wall behind your listening spot to catch the sound that passes your ears and bounces back toward you. A few panels centered behind your head do more here than a full wall of foam, because this wall feeds echo straight back to the listening spot. If the room still rings after the side walls and the front wall are done, add more panels here.
Treat the ceiling and the corners
Hang panels on the ceiling above the listening spot, where sound from the speakers bounces down to your ears. Corners collect low sounds, so a panel in each upper corner helps where the walls meet the ceiling. Use adhesive tape or pads made for foam panels, and press each panel flat so its edges sit flush with the wall.

Frequently asked questions
How many acoustic panels do I need?
It depends on the size of the room and how much echo you hear, so start with the side walls at ear height and the wall behind you, then listen and add panels where echo remains. A room with hard bare walls needs more coverage than a room with soft furnishings.
Do acoustic panels keep outside noise out?
No. Acoustic foam panels absorb sound inside the room and cut echo and reverberation, but they are not made for full soundproofing or keeping outside noise out. To stop noise from outside, you need a different kind of treatment.
Can I put acoustic panels on the ceiling?
Yes. Hang panels on the ceiling above your listening spot, where sound from the speakers bounces down to your ears, using adhesive tape or pads made for foam panels. Check that the ceiling surface is clean, dry, and smooth before you mount them.
