DIY acoustic panels are gaining popularity as a cost-effective alternative to commercial options. These panels play a crucial role in absorbing sound energy, preventing it from bouncing off walls and other hard surfaces. They are especially beneficial for dampening echoes and reducing reverberation in any given space.

In the following sections, we’ll outline the essential materials needed to create your own acoustic panels. Additionally, we’ll walk you through the construction process and provide guidance on how to properly install them once they’re completed. This DIY approach not only saves money but also allows for customization to fit your specific acoustic needs.

Tips for Making DIY Acoustic Panels(1)

What kind of fabric for acoustic panels?

When selecting fabric for acoustic panels, the key is to choose a material that allows sound to pass through without much reflection but more sound absorption.

Some of the factors to keep in mind when selecting fabric for acoustic material include:

Functionality

The material you choose should allow sound to penetrate through it while keeping the fibers in place.

You also want to check on tear strength to ensure that you get a material that will last. Some materials even come with a fire-retardant finish which is great if you live in a fire-prone area.

A 100% polyester faux linen is excellent for the job. The material is lightweight, breathable, and durable. Other materials that stand out include natural fabrics like linen, wool, and cotton canvas.

Breathability

The breathability of the material you select for your acoustic panels plays a crucial role in their effectiveness. Ideally, the fabric should be without any backing and possess enough permeability to let sound waves pass through effortlessly.

A practical way to test the suitability of the fabric is the “breath test.” Place the fabric over your face and try breathing through it. If you encounter significant resistance while breathing, then the material may not be the best choice for acoustic panels. This test helps ensure that the fabric is not too dense to impede sound waves, ensuring optimal acoustic performance.

Visual Appeal

Who says that acoustic panels have to be boring? With the right material, you can transform them into beautiful art pieces.

First, you have to think about the above two features before you can narrow your search down to visual appeal. However, for the color and pattern, you are free to select the ones that match the rest of your décor.

If you are artsy, be bold and go for colors that represent your personality. You can also mix plain and patterned materials and decoratively arrange the panels.

Fabric types commonly used for acoustic panels

When creating acoustic panels, the choice of fabric is essential for ensuring effective sound absorption and minimal sound reflection. Here are some commonly used fabric types:

  • Acoustically Transparent Fabric: This specialized fabric is designed to allow sound waves to pass through without significant distortion or absorption. It’s often used in professional-grade acoustic panels and speaker covers.
  • Burlap: Burlap is a popular choice for DIY acoustic panels due to its rough, open weave. It allows sound to pass through easily and is also quite affordable and available in various colors.
  • Muslin: A lightweight cotton fabric, muslin is known for its acoustic transparency. It’s easy to work with and can be dyed to match any décor.
  • Microsuede: Microsuede is a thin, breathable fabric that offers a more upscale look for acoustic panels. While it’s more expensive, it provides good sound transparency and adds a touch of elegance.
  • Felt: While felt is denser than other fabrics, thin felt can be used for acoustic panels. However, it’s important to ensure that it’s not so thick as to absorb too much sound, especially high frequencies.
  • Guilford of Maine Acoustic Fabric: This is a premium fabric option often used in professional settings. It’s specifically designed for acoustic applications and comes in a variety of textures and colors.

Each of these fabrics offers a balance between aesthetic appeal and functional sound absorption, making them suitable for various acoustic panel projects.

Steps on How to Build DIY Acoustic Panels

If you opt not to purchase acoustic panels and want to make some nicer on your own, then below guide will help get started. You need to make a proper plan to determine the materials you will need to complete the project. What size do you plan to cover?

Take measurements of the wall’s length and height. If you plan to install panels on all walls, add the numbers to see how much of each material is required.

1. Choose A Sound Absorbing Core Material

There is a wide range of sound-absorbing materials in the market, so choosing one can be confusing.

Foam is common and preferred by many because it is easy to work with. Dense fibreglass or mineral fibre insulation also works great. Just ensure that you do not choose the loose batt material.

The density of the material you choose will determine how effective it will be in improving the acoustics in your home. You may have to pay more for the thicker sound-absorbing materials, but the investment is well worth it.

The material must meet the following requirements:

  • 2” thickness
  • 3lb to 8lb cubic foot density however 6-8pcf is ideal

The acceptable materials that I would highly recommend include:

Mineral wool and fiberglass insulation are known irritants, it’s important you wear protective gear including gloves, masks, and glasses when dealing with the insulation.

2. Build A Wooden Frame Around Each Acoustic Panel

You will need to build a wooden frame around each panel.

In my case, I used a 1”x2” strip which is readily available at my local lumber supplier.

Inspect every strip to ensure that it’s straight and not missing any significant pieces of wood.

  • Cut the acoustic panels to snugly fit the wooden frame.

Once done, apply a heavy dose of acoustic sealant or spray adhesive to the edges of perimeter insulation (don’t apply to the front face) the glue will hold the acoustic insulation in place within the wooden frame.

Use wood glue or screws to ensure that wooden frame sticks are strongly held together.

Align the panels to the wooden frame making sure that the frame sits securely around the insulation and allow up to 24 hours for the spray adhesive and glue to dry.

3. Cut material/wrap the panels

Cut the material you will use to cover the panels. The size of the material will be dependent on the size of the panels. Ensure that the material is about 6 inches wider or longer than the panels so you can easily wrap it around the edges.

Once all pieces are cut, place the panel on the material face down. Take one side of the material, wrap it around the edge, and staple it in place.  

You can as well apply spray adhesive like MITREAPEL Super CA Glue to firmly hold the fabric to the panels.

Once one is secure, pull the material as tight as possible and staple the other side. You do this to ensure that your panels have a clean/neat finish.

4. Mount Your Panels

Now that your panels are all well covered in good-quality fabric, you just need to install them on the desired surface.

Your installation method will depend on where you are hanging them. For example, picture hooks and D-rings work great for the ceiling, while double tape may be better suited for the walls.

The goal is to attach the panels to the surface without causing much damage to it. Check out YouTube for inspiration and guidance on acoustic panel mounting.

To make your panels movable, you can mount the panels on cardboard. All you have to do at this point is cut the cardboard to the size of the panels and glue two parts together.

You can also frame the panels using wood. The resulting product will be not only effective in minimizing echoes but also easily movable. Since the cover material can be any color or pattern you want, framing works great if you want to convert your acoustic panels into art pieces.

You can paint on acoustic panels. I’d recommend you use acoustic paint, such as Acousti Coat – Sound Deadening Paint.

Final thoughts

In wrapping up our guide on creating DIY acoustic panels, it’s clear that with the right materials, tools, and a bit of patience, anyone can enhance their space’s acoustic quality. The journey of assembling these panels not only offers a satisfying DIY project but also an opportunity to tailor your acoustic environment to your specific needs.

Remember, the choice of fabric and the quality of the insulation material are pivotal in determining the effectiveness of your panels. Balancing aesthetics with functionality is key. Whether you’re looking to improve the sound quality in a home theater, recording studio, or just seeking a quieter living space, these panels are a practical and customizable solution.
