FAQ - Frequently Asked Questions


How many acoustic panels do I need?  How many panels should I purchase for my room? How do I calculate how many panels I need for my sound problem?

Keywords: amount, quantity, consultation, formula

We recommend covering at least 15-20% of a room's walls in sound absorbing acoustic paneling. That's the industry standard formula to achieve adequate sound absorption in most noise-prone indoor spaces. I'd be happy to help calculate the quantity of recommended panels for your situation, I'll just need the length, width, and ceiling height of the room and we'll go from there. Alternatively, you can use our online calculator here:  https://www.acousticdesignworks.com/pages/calculator


Can I get swatches of your fabric colors?  Can I get fabric samples of your standard colors?

Keywords:  fabric, swatches, samples, Guilford of Maine

We’d be happy to send out our fabric swatches. The fabric swatch cards in include all of the colors available in Guilford of Maine’s Anchorage and FR701 styles. Those are the acoustic fabrics that we typically use to make our panels. All we need is your mailing address and we’ll send them out to you ASAP. Please contact us here with that information.


Can I get a sample acoustic panel?

Keywords:  sample panel, 12”x12” square sample

If you'd like to see the quality and feel of the acoustic panels, we can sell and ship you a 12"x12"x1" sample panel for $50. That includes shipping. We'd then credit you the $50 against a larger order. Let us know if you're interested in that and I'd just need your address and the fabric color you'd want. You can contact us here.


Will these sound panels stop these sounds from passing through walls?

  • Voices coming through walls in office
  • Noisy neighbors
  • Snoring neighbors
  • Barking dogs
  • Loud music from neighbors
  • Loud TV from neighbors
  • Thin apartment walls
  • Noisy air conditioning unit outside window
  • Train noise outside
  • Garage band, don’t want to annoy neighbors
  • Bass vibrations

Keywords:  walls, wall transmission, sound proofing, sound proof

Regarding sound from loud neighbors in an apartment acoustic wall panels will absorb some sound, but they won't block it completely.  It would likely take a lot of coverage to make a difference. Acoustic wall panels are designed mainly to reduce sound (echo, noise, reverb) within a room, while reducing sound traveling through walls to a lesser degree.  It's a tough problem to tackle and sorry to say, the only sure-fire solution is thicker walls or quieter neighbors. 


What is the noise reduction coefficient (NRC) of the panels?

Keywords:  NRC, noise reduction coefficient, noise control, sound absorption

The acoustic panels with 2" core are rated NRC 1.0 (noise reduction coefficient), while the 1" core panels are rated NRC .85. What this means in general is the 2" panels absorb around 15% more of the spectrum of sound frequencies including more of the lower range (bass). 


Can these panels “sound proof” a room?

Keywords:  soundproof, sound proof, soundproofing

You can achieve a high degree of sound reduction, with a large amount of thick acoustic panels on the wall in the room with the noise source.  That said acoustic wall panels are designed mainly to reduce sound (echo, noise, reverb) within a room by absorbing the sound waves bouncing in the room, while reducing sound traveling through walls to a lesser degree.  Acoustic panels alone technically are not adequate to truly "soundproof" rooms.  To truly soundproof a room, you need a large amount of thick panels, thicker concrete walls, or an acoustically isolated room.  Again, however, you can dampen the sound transmission greatly with a large amount of panels on the wall in the room with the noise source.


How do you install these acoustic panels on the walls?

Keywords:  installation, mounting, mounting hardware, impaling clips

Regarding wall installation, we include the necessary amount of 8-prong impaling clips to mount the panels (see instructional video here). We do not include screws because wall substrates vary (drywall, brick, wood, etc.). Accordingly, we leave it up to the installer to determine the appropriate screw and mounting system for the wall situation. These acoustical panels mount easily to the 8-prong impaling clips, but it's important the clips are solidly attached to the wall with the appropriate screws. Note, 8-prong impaling clips should not be used for ceiling installation.


Is mounting hardware included with the order? Are screws included with the acoustic panels and mounting hardware?

Keywords:  mounting, installation, screws, mounting hardware, 8-prong impaling clips

We include impaling clips but since wall substrates vary (drywall, brick, wood, concrete, etc.) we do not include screws for the mounting the impaling clips to the wall. We leave it to the installer to choose and purchase the appropriate screws for the type of wall the panels are to be mounted on.  To help out, here's a video showing the installation process: https://www.acousticdesignworks.com/pages/installation


Can I attach the acoustic panels to the walls with tape, adhesives, or command strips?

Keywords: installation, command strips, tape, adhesives

Unfortunately, we have not tested using double sided adhesive products like Command Strips or other adhesives to mount the panels, so we can't vouch for that method. The backs of our panels are flat and covered in a layer of scrim textile and the adhesive strips may not adhere well to the scrim in the long run. The mounting hardware we include (8-prong impaling clips) are the most secure way to mount the panels to your wall.


Is ceiling installation possible? How do you install these panels on the ceilings?

Keywords:  ceiling installation, mounting, mounting hardware, impaling clips

For ceiling installation you can mount the acoustic panels in two ways:

  1. Ceiling mount by screwing the panels flat on the ceiling using the appropriate screws for the ceiling substrate. Pan or truss head screws are recommended. You'd drill the screws straight through the panels and into the substrate. 
  2. Or we can provide Rotofast Cloud Anchors for hanging the panels from the ceiling. The cloud anchors “corkscrew” into the back of the panels and they have a ring that you use to hang the panels from the ceiling.

Either way, we highly recommend having a professional install acoustical ceiling panels (to make sure they don't fall down).  Note, 8-prong impaling clips should never be used for ceiling installation.


Do you make baffle panels (with fabric on both sides) for hanging from the ceiling?

Keywords: acoustic baffles, ceiling, double-sided, fabric on both sides

Yes, we do make acoustic baffles with fabric on both sides and embedded rings for hanging from a ceiling. Please contact us here to discuss.


Does this product have a fire rating?

Keywords: fire rating, smoke rating, burn, fire safety

All components utilized in the construction of these acoustic wall panels meet a Class A (1) rating as tested per ASTM E-84 (measurements of surface flame spread and smoke development). This is the highest and safest fire rating possible for building materials. 


Is this product tackable? Will using tacks damage the panels?

Keywords:  tack, tackboard, tack board, tackable

Yes, these acoustic panels are tackable. The acoustic core will hold pins and tacks without any damage to the panel. Also, the Guilford of Maine fabrics we use are "self-healing" when tacked with pins or thumbtacks. This makes our panels great for offices and classrooms.  All that said, if you do cover a substantial amount of the panel in paper, then sound will not be absorbed as efficiently since it'll be reflecting off the paper. I'd keep the paper placed on them to a minimum.


Is there a recommended space between panels?  Is it a problem if there’s too much spacing between the panels?

Keywords: spacing, installation, mounting

No, as long as you have the sufficient quantity of acoustic panels and achieve the minimum recommended coverage then the distance between panels doesn't matter.


Where should I mount the acoustic panels in the room? What’s the ideal configuration?

Keywords: installation, mounting, configuration

In general, it's recommended to disperse the panels throughout the room as evenly as possible.


Do you make custom sized panels? What are the largest panels you can make?

Keywords:  custom size panels, custom sizes, custom sized

Yes, we can make acoustic panels in almost any size and shape up to 4’x8’.  Please give us a list of your panel quantities and dimensions and we can get a quote started for you.  Also please send your shipping address and we’ll get a shipping cost as well. Note, for panels bigger than 48”x24” in size, we may need to ship via LTL (less than truckload) freight service. If that’s the case we’ll have a few more questions. Contact us here to discuss.


Can these acoustical panels be cut down to size?

Keywords:  cut panels, cut down to size, resize panels, custom sizes

No, our panels are not meant to be cut down. The acoustic panels are made of a sound-absorbing fiberglass core with the exterior wrapped in scrim and Guilford of Maine acoustic fabric. So cutting the panel would irreparably damage the finished exterior. If you're interested in different sizes or shapes that you can't find in our store, please contact us here and we would be happy discuss!


How do these acoustic panels compare to foam eggcrate-style panels?

Keywords:  fiberglass vs foam, eggcrate, pyramids

Our acoustic panels (acoustic fiberglass core) will generally absorb about twice as much sound as foam eggcrate/pyramids/etc. and they'll do a great job of absorbing unwanted noise, echo, and reverb.


What are the components of the panels? What materials are used to make this? Is it a wood frame? What if the material inside the panel? Is the fabric breathable?

Keywords: materials, frame, hardened edges, fiberglass, fabric

Our acoustic panels are made from a dense, sound-absorbing fiberglass core wrapped in scrim (a thin textile layer) and then wrapped in an acoustically-transparent polyester fabric by Guilford of Maine. Acoustic transparency means that sound waves can pass through and be absorbed by the core, rather than bouncing off and echoing around the room. The fabric is very porous, so I guess you could say its breathable. The edges of the fiberglass core are hardened for stability - there is no wood frame.


Do you sell acoustic foam for attaching under chairs and tables in a restaurant? Does that method work for absorbing sound?

Keywords:  foam, restaurant, under tables, chairs

We haven’t tested foam under chairs and tables and can’t recommend it. The downsides are likely that they don't absorb very much sound because foam is thin and not dense. The other potential problem is the foam may disintegrate over time and create a mess.


Can the acoustic panels handle high humidity or moisture?  Can you use the panels in a yoga studio?

Keywords:  humidity, wetness, dampness, water, damp, moisture

Our panels stand up well to high humidity. That said, the panels should never remain wet indefinitely. Just like with any material, if left damp, then molds will likely form over time. It's important that the room has good ventilation and the walls and panels are allowed to completely dry in between classes and/or overnight.


Can the acoustic panels be used in on an outdoor patio space or lanai that is covered and protected?

Keywords:  outdoors, lanai, covered patio

It’s not an ideal place to put them, but our panels can be used in an outdoor space if it is far from and well-protected from the elements (rain, wind, etc). The panels will withstand humidity well but should not remain wet. Just like with any material, if left damp, then molds will likely form over time. And just like any furniture or fabric-covered items, they may not have the same longevity if they're exposed to outdoor weather as items kept indoors.



How much does it cost to ship these acoustic panels?

Keywords: shipping costs, ship, transport

As shipping costs vary, if you send us a list of the panels you’re interested in and your shipping address, we’d be happy to get you a quote.  Normally the panels ship via UPS Ground, but if it is a large order or if the panels are over 48”x24” in dimensions we’ll usually ship via LTL (less than truckload) freight carrier.


LTL accessorial questions

What are the considerations for shipping via LTL? 

Keywords:  LTL, accessorials

For panels that are bigger than around 48”x24” in size we may need to ship via LTL freight, so we will need this info:

- Is there a loading dock at the delivery location?
- Do you need the driver to help bring the panels inside (or will there be people there to bring them in?)
- Do you need a delivery appointment, or will there be people there during normal business hours to accept the panels?

Please provide that info when ordering. Contact us here to discuss.


Can you ship these sound panels internationally?

Keywords:  ship, shipping, international

Thanks for your interest. Unfortunately, we currently only ship within the US and Canada.
