Most items that absorb sound are temporary, while others are more permanent. When looking for the perfect material to muffle your noise pollution, there are several things to keep in mind. These factors include price, installation time, durability, and reusability of the product. Here is a list of 7 sound absorbing materials:
1). QUILTED FIBERGLASS PANELS:
Quilted fiberglass panels can be hung like wallpaper or easily attached with adhesive strips or glues (for both). The quilting allows them to trap air inside each pocket space, making it easy for sound waves to pass through without hitting any hard surfaces. This means there is no glare from the product and no echo.
2). FABRIC-COVERED SOUND ABSORPTION PANELS:
Fabric-covered sound absorption panels are available in a variety of sizes to fit any space. These sound absorbers are made with fabric specially designed to absorb noise pollution while looking like the original decor. They come with or without backs, allowing them to be hung on a wall or attached with adhesive strips/glues for free-standing installations that can be moved easily if necessary.
3). ACOUSTIC INSULATION:
Acoustic insulation comes in many forms, including anything from foam (such as Green Glue) to egg crates or fiberglass tiles. This material must be installed at specific intervals, such as every 16 inches, along with wall studs or ceiling joists, allowing acoustic energy to be properly absorbed.
4). POROUS ABSORBENT PAINT:
Porous absorbent paint is perfect for controlling sound that leaks through walls and ceilings or in industrial environments where noise levels are extremely high. This product is often used when there isn’t much room to install traditional products such as insulation or drywall. It can turn any surface into a sound-absorbing wall (or ceiling) and looks like regular latex paint. It has an appearance similar to standard latex paints contains tiny particles made from silica which causes the paint to absorb noise. Porous absorbent paint can also be easily painted over and provides excellent sound absorption with almost no loss of surface space in the area you’re painting on.
5). ACOUSTICAL WALL PANELS:
Suspended acoustical wall paneling is a system of treatment that consists of pre-fabricated components designed to provide sound absorption control in open spaces without loss of surface area or aesthetics. This type of system may consist of one or more material types using various mounting heights to be used on different surfaces. The suspended underlayment helps keep costs low while providing effective treatment for broadcast studios, music rooms, classrooms, and other large areas requiring sound isolation without sacrificing space or ceiling height.
Quiet Board™ fiberglass insulation with mass-loaded vinyl facing offers the highest overall STC (Sound Transmission Loss) and IIC (Impact Isolation Class) ratings of any insulation available. When installed, it acoustically transforms a room to reduce echoes, reverberation, and standing waves – the leading cause of poor sound quality. The Quiet Board™ can be used in wall construction and floor/ceiling assemblies where additional acoustic isolation is required.
7). FOAM PANELS:
Foam panels are some of the most popular options for absorbing sound inside a home or office because they’re easy to install with glue, screws, staples, or nails. These can be installed anywhere, including on walls, floors, and ceilings, to absorb sound in your space. They’re also very lightweight, which makes them a great option for installing on a DIY project or if you rent your home and aren’t allowed to make major changes without consulting your landlord.
A sound-absorbing material can be anything that absorbs some of the noise around it rather than reflecting all of it into the atmosphere. This means any porous item (such as fabric, insulation, or paint) can act as a sound absorber depending on where you install it and how much mass is included in the construction. There are also different materials available for large-scale or industrial noise absorption, like acoustical wall panels, which are great for broadcast studios, music rooms, and other open spaces with high noise levels.
