ACOUSTIC PANEL QUESTIONS, ANSWERED WITH MEASUREMENTS
How many acoustic panels does a room need?
Most small rooms, like a 10×12 ft home office, bedroom or nursery, need two or three art-sized acoustic panels before you can easily hear the difference. One panel helps, but it is subtle.
We measured it. In a 12×10×8 ft office, one 24×24 frame cut echo in the speech range by 7%, two by 11% and three by 15%. A 24×36 frame is 50% bigger, so we estimate about 10% for one and 21% for three. Bigger or barer rooms need more. The Quiet Calculator on this page does the math for your room.
How do I reduce echo in a room?
Add soft, sound absorbing surfaces. Echo is sound bouncing between hard walls, floors and ceilings. Rugs, curtains, soft furniture and full bookshelves all help, and acoustic panels do the most per square foot. In our test, three 24×24 frames on two walls cut echo in the speech range by 15% in a furnished 12×10 ft office. Start with the walls nearest where you sit or talk.
Do acoustic panels actually work?
Yes, for echo inside a room. With three 24×24 frames on the walls, reverb time in the speech range dropped from 0.60 to 0.51 seconds, and voices came through clearer.

Do acoustic panels soundproof a room?
No. Acoustic panels absorb sound that bounces around inside a room. They do not block sound from passing through walls, doors, floors or windows. The room sounds calmer and voices are clearer, but panels will not stop traffic, neighbors or noise from the next room. Soundproofing takes mass and sealed gaps, which is construction work.
Acoustic panels vs. foam: what is the difference?
Rigid fiberglass panels absorb more sound per square foot than foam, and they reach lower frequencies. Each Muted Collection frame holds 2 inches of Owens Corning 703, an NRC 1.0 absorber. A typical 1 inch foam tile is rated around NRC 0.40, and brand-name 2 inch foam around NRC 0.80.
One frame absorbs nearly three times as much as a typical 1 inch foam tile of the same size, and about a third more than brand-name 2 inch foam.
Do acoustic panels help in a kid's bedroom, playroom or nursery?
They reduce echo, which makes a room sound softer. Hard floors and bare walls make voices, toys and footsteps ring, and panels shorten that ring. They do not block noise from other rooms.
Some families of sound-sensitive kids use acoustic panels to make a bedroom or playroom calmer. Our panels are wall art that absorbs echo, not a medical product or a treatment. See our Quiet Room page for details.
Where should acoustic panels go on the wall?
Hang them at ear height and spread them out. Two panels on facing walls, or on the two walls of a corner, catch reflections that a group on one wall misses. Near a desk or microphone, start with the wall you face and the wall beside you.
Do acoustic panels absorb bass?
Not much. A 2 inch panel works from about 250 Hz up, which covers voices and most everyday noise. Deep bass needs much thicker bass traps.
What does NRC 1.0 mean?
NRC is the Noise Reduction Coefficient: the share of sound a material absorbs, on a scale from 0 to 1. Owens Corning rates 2 inch 703 board at NRC 1.00, and our own measurement of the finished frame averaged about 1.0. That is a field estimate.
What is an acoustic art panel?
An acoustic art panel is a sound-absorbing wall panel with artwork printed on its fabric face, so the art is the absorber. The Muted Collection makes limited edition acoustic art panels: artist prints on handmade poplar frames, built in Phoenix, Arizona. Each piece is numbered out of 67 and comes with a certificate of authenticity, in 24×24 or 24×36 inches, with a one-screw magnetic mount. Frames start at $390 with free US shipping and are made to order in up to 30 days.
