Soundproofing 101: Installing Sound Foam Like A Pro

how to put up sound foam

Acoustic foam panels are designed to absorb sound waves, reducing echo, reverb, and unwanted sound reflections in a room. This is particularly useful for those recording or creating music, as sound bouncing off walls can affect recordings and create unwanted effects. To hang acoustic foam, you must first decide where to place it. You can then use spray adhesive, command strips, small nails, or thumbtacks to attach the foam to the wall. For a less permanent solution, you can attach the foam to cardboard, plywood, or coroplast, and then rest or hang the assembled panel on the wall.

Using adhesive spray and cardboard

First, clean and measure the areas you plan to treat, such as the space between your studio monitors and speakers, and the wall across from your speakers. Once you've decided where to hang your foam, wipe down the walls with rubbing alcohol to ensure the foam will stick.

Next, spray the back of the foam pieces with adhesive spray and press them against pieces of cardboard. Let the glue dry completely, which should take around 1-2 hours. Then, add command strips to the backside of the cardboard pieces and stick them to the wall. Press the foam against the wall for around 30 seconds to make sure it sticks.

If you're renting or want to be able to reposition your panels, you can mount the acoustic foam to cardboard using adhesive spray and then rest or hang the assembled panel on the wall. This method won't damage your walls, and it gives you the freedom to move the panels around for sound testing or take them with you when you move.

Using command strips

Step 1: Clean and Measure the Wall

Start by cleaning the wall surface with rubbing alcohol to remove any dirt and ensure the command strips will adhere properly. Avoid using household cleaners as they may interfere with the adhesive. Once the wall is clean, measure the area you plan to cover with acoustic foam. This will help you determine the placement of the foam panels and ensure a neat installation.

Step 2: Prepare the Acoustic Foam

Purchase enough command strips to accommodate the number of acoustic foam panels you plan to hang. Four strips per tile is recommended for a superior hold, especially if you are hanging heavier panels. Separate the strips and apply them to the backside of the foam panels. Place one strip in each corner of the foam, ensuring the strips adhere directly to the cardboard backing of the foam, not the foam itself.

Step 3: Attach the Acoustic Foam to the Wall

Once the command strips are securely attached to the foam panels, you can begin affixing them to the wall. Remove the liner on each command strip to expose the adhesive material. Carefully line up the edges of the foam panels, ensuring they are straight and level. Press each strip firmly against the wall for at least 30 seconds to ensure a strong bond.

Step 4: Complete the Installation

Repeat the process for each foam panel, carefully aligning the edges with neighbouring tiles to create a seamless finish. Once all the panels are in place, your acoustic foam installation is complete! This method allows for easy adjustments or removal without damaging your walls, providing a flexible and damage-free solution for sound control in your space.

By following these steps, you can effectively install acoustic foam using command strips, creating a more controlled sound environment without causing any damage to your walls.

Installing behind recording equipment

Acoustic foam is an important addition to any recording studio, helping to absorb unwanted sound waves and prevent echoes. It is particularly useful when recording vocals, as it can prevent the reflected sound from entering the microphone and creating an echo.

To install acoustic foam behind your recording equipment, first, identify the optimal area on the wall to place the panels. This is usually behind your mixer or desk, or behind your monitor speakers, with an additional panel opposite them. If you're recording vocals, you may also want to place a panel directly in front of the vocalist, or use a high-tog duvet, which can be cheaper and easier to hang.

Next, take measurements of the wall and the foam panels. Mark out the area on the wall where you want to install them, so you know how much space they will take up. If you need to cut the foam panels to size, use an electric carving knife, holding the panel on its thin end and cutting down through the foam.

Before adhering the panels to the wall, wipe down the wall with a clean cloth and rubbing alcohol to remove any dirt. This will help the foam to stick.

Finally, adhere the panels to the wall. You can use Command strips, adhesive spray, or push pins, depending on your wall type and how permanent you want the installation to be. If using adhesive spray, spray the back of the foam pieces and press them against cardboard before adding Command strips to the back of the cardboard and pressing it to the wall.

By installing acoustic foam behind your recording equipment, you can effectively reduce sound reflections and improve the sound quality of your recordings.

Positioning between speakers

When positioning sound foam between speakers, it is important to consider the unique characteristics of your space and your specific goals. Here are some detailed instructions and tips for installing and positioning sound foam between speakers:

  • Cleaning and Measuring: Start by cleaning and measuring the area between your speakers. Wipe down the walls with rubbing alcohol to ensure that the surface is free of dirt, which will help the foam adhere better. Measure the space between your speakers to determine the amount of foam needed and plan out the placement.
  • Mounting Options: There are several methods for mounting sound foam. One popular technique is to use spray adhesive. Spray the back of the foam pieces with adhesive and press them against cardboard. Then, attach Command strips to the cardboard and secure them to the wall. This method is effective and allows for easy repositioning without leaving residue on the walls. Alternatively, you can mount the foam directly to the wall using Command strips by placing the strips directly on the backside of the foam panels.
  • Placement Considerations: When positioning the foam between speakers, consider treating the first reflection points on the horizontal axis. Sit in your listening position and identify where sound from the speakers hits the sidewalls and bounces back to you. Placing acoustic treatment in these areas will improve stereo width and imaging clarity. Additionally, consider placing foam across corners of the room, creating an "acoustic cloud" hanging from the ceiling above your listening position.
  • Bass Traps and Absorption Panels: While foam can help with echo reduction, it might not be as effective for blocking low-frequency sounds. For better bass control, consider using bass traps, especially in the upper corners of the room. Broadband trapping and absorption panels can also be more effective at reducing unwanted reflections and improving sound clarity.
  • Avoid Overdoing It: While acoustic treatment can improve sound quality, too much foam can have the opposite effect. Be cautious not to cover all surfaces with foam, as it can make the room feel uncomfortable and cause the musical quality to sound unnatural. Aim for a balanced approach, covering around 20-30% of your wall space for general echo reduction.

Remember, the placement of sound foam between speakers is just one aspect of acoustic treatment. For optimal results, consider treating other areas of your room, such as the front and back walls, sidewall reflection points, and the ceiling above your listening position. Each space is unique, so feel free to experiment and adjust the placement to achieve the desired sound.

Hanging with distance from the wall

When hanging sound foam with a gap between the foam and the wall, one effective method is to use a combination of furring strips and acoustic clips. This method ensures that the sound foam is securely attached to the wall while maintaining the desired distance. Here's a step-by-step guide:

Prepare the Furring Strips and Acoustic Clips:

  • Determine the desired distance between the sound foam and the wall. This distance will influence the length of the furring strips you'll need. Furring strips are thin, flexible wooden strips that can be found at most hardware stores.
  • Cut the furring strips to the appropriate length based on the desired distance from the wall. For example, if you want the sound foam to be 2 inches away from the wall, cut the furring strips to a length of around 3 to 4 inches, allowing for some adjustment.
  • Purchase or acquire acoustic clips. These are specially designed clips that attach to the furring strips and hold the sound foam in place. They typically come with a hole for screws and a gripping mechanism to hold the foam.

Attach the Furring Strips to the Wall:

  • Decide on the placement of the sound foam panels and mark the locations for the furring strips on the wall. Typically, you'll want to attach the furring strips vertically, spaced evenly across the area where the sound foam will hang.
  • Use a stud finder to locate the wall studs. You'll want to secure the furring strips directly into the studs for a sturdy installation. Mark the stud locations with a pencil.
  • Drill pilot holes into the wall studs at each marked location. The holes should be slightly smaller than the screws you'll use to attach the furring strips.
  • Hold a furring strip against the wall, aligning it with the pilot holes, and secure it in place using appropriate screws and a power drill. Make sure the screws are long enough to penetrate the wall studs for a firm hold.
  • Repeat this process to install additional furring strips, spacing them evenly to support the sound foam panels.

Hang the Sound Foam:

  • Attach acoustic clips to the installed furring strips. Space the clips evenly along each furring strip, typically one clip near the top, one in the middle, and one near the bottom of each foam panel.
  • Insert the edges of the sound foam panels into the acoustic clips. These clips should have a gripping mechanism that holds the foam securely in place.
  • Adjust the position of the foam panels as needed to ensure they are straight and aligned correctly.
