Set up acoustic panels by placing them on the walls where sound reflects, then mounting them with adhesive tape or pads. The panels absorb sound and reduce echo in a room used for recording, gaming or calls. Start with the wall behind your speakers or microphone, then add panels to the side walls until the echo drops.
Plan where the panels go
Walk around the room and clap once to hear where echo lingers, then mark the bare wall behind your speakers or microphone and the side walls beside your listening spot. Acoustic foam absorbs sound instead of blocking it, so it calms echo inside the room rather than keeping outside noise out. Cover the first reflection points first, then add panels where echo remains.
Let the panels expand and check the fit
Open the packs and lay the panels flat so they regain their shape before you mount them. The TOUO panels expand within 24 to 48 hours, and the Knightsacoustic panels recover their shape within 3 to 5 hours. Hold each panel against the wall to check the layout and spacing before you stick anything down.
Mount the panels with tape or pads
Clean the wall so it is dry and smooth, since the Temgcuam panels stick best to clean, dry, smooth surfaces. Press the TOUO tape or the Temgcuam adhesive pads onto the back of each panel, then press the panel firmly onto the wall. The SD SODOCT panels mount with construction adhesive or nano double-sided tape, which is not included.
Cover the ceiling and corners last
Once the walls are covered, add panels to the ceiling above your listening spot if echo remains. The SD SODOCT, Knightsacoustic and Temgcuam panels all mount on ceilings as well as walls. Step back and listen after each round of panels, and stop adding them once the echo sounds even across the room.

Frequently asked questions
Do acoustic panels keep outside noise out?
No. The panels absorb sound inside the room and reduce echo, but the SD SODOCT panels are not intended for full soundproofing or noise isolation from outside.
Can I move the panels after mounting them?
The TOUO tape allows residue-free removal, so those panels can come off the wall without tearing paint. Panels fixed with construction adhesive are harder to move, so check the layout first.
How many panels do I need?
It depends on the size of the room and how much echo you hear. The packs here hold 12, 24, 50 or 54 panels, so count the wall space you plan to cover and pick a pack that covers it.
Do the panels include adhesive?
The TOUO pack includes 60 pieces of double-sided adhesive tape, and the Temgcuam pack includes 270 adhesive pads. The SD SODOCT and Knightsacoustic panels do not include adhesive, so buy tape or adhesive separately.
