What is a soundproofing material?
Soundproofing is a method of decreasing the sound pressure concerning a specified sound source and receptor. The materials we use to achieve this are known as soundproofing materials.
The inventor of soundproofing:
Soundproofing started in the 1890s with a man named Wallace Clement Sabine. Sabine, a physicist at Harvard University, moved into this world when he was asked to figure out a way to enhance the acoustics inside the main lecture hall in Harvard’s Fogg Art Museum. He started by mapping reverberation time; he is the first person we know to do this. Obtaining the reverb time to be 5.5 seconds, he started experimenting with different seat cushions, then with sound-absorbing elements.
How do soundproofing materials work?
Soundproofing materials work by absorbing sound, dampening sound vibrations, barring them at the source, or mixing all three. Sound Absorption: Sound absorption is done using soft, porous, open-celled foams such as polyurethane foam, which confine sound waves within the foam's maze of non-reflective cells. The higher the ratio of sound block surface area to open space, the higher the sound absorption. To achieve this, anechoic chamber manufacturers fill walls, ceilings, and even floors with ridged foam wedges or boards with a pyramid or egg-crate shaped surfaces. They absorb far more sound than flat foam or other acoustic boards.
Vibration Dampening: Vibration dampening decreases the amount of vibration energy transferred between surfaces constructed of hard materials, usually transmitting vibrations at various frequencies. Product testing rooms and acoustical research centers, use vibration dampening to create minimum noise pollution. Often, this dampening comes in the form of anechoic chambers, or noise control rooms wholly filled with acoustic foam panels, acoustic drywall, and acoustical roofs. These rooms absorb almost all the sound waves created by a piece of equipment or machine. Sound Barrier Creation: Sound barriers are real barriers that block the noise source and decrease its effects. Sound barriers frequently come in the form of walls of high-density material. Most often, you can find them along a road or highway, muting the sound of cars. However, they’re also commonly used as firewall treatments, bulkheads, pipe wraps, and cab floors.
6 best soundproofing materials:
The top 6 most popular soundproofing materials are discussed below:
- Acoustic Foam (Auralex Studio foam Wedges):
Best Use: For adjusting the sound in small to medium rooms, like recording studios, control boardrooms, and even small home theaters.
- NRC: 0.8
- Size: 12”x12”x2.”
- Colors: Charcoal, Burgundy
Use 3M Command bands, hook and loop strips, or spray adhesive to fix the foam to your room’s walls and roof. If you ever intend to move them, it’s highly advised to use the detachable type of adhesive strips to remove it easier.
- Sound Absorbing Foam (Pro Studio Acoustics Tiles):
Best Use: You can use it as an alternative to the Auralex panels. They offer many attractive colors to break up with the charcoal that looks excellent in any room.
- NRC: 0.65
- Size: 12”x12”x2.”
- Colors: Charcoal with Blue, Red, Teal, and Purple.
Many people use the Pro Studio Acoustic foam panels for absorbing sound in both home and professional use. The vibrant, bright colors liven up theater rooms, gaming rooms, voice counters, and studios while absorbing sound and stopping echoes.
- Acoustic Panels (ATS Acoustics):
Best Use: Acoustic panels are best for rooms where the wedge and pyramid foam shape is awkward. The wood-framed panels seem more like decor or large picture frame than a sound-absorbing panel.
- NRC: 1.0
- Size: 24”x48”x2.”
- Colors: Beige, Black, Burgundy, Ivory.
All that’s given is to hang them on the wall with the added hardware. It’s essential to note the ATS Acoustic panels are sold as single panels. You can always buy many panels at one time to save on shipping charges.
- Acoustic Curtains (Utopia Thermal Blackout Curtains):
Best Use: Blackout curtains are useful for decreasing the noise coming in or getting out of windows and doors. Use them in a bedroom, home theater, nursery, or wherever a little quiet is required. A typical acoustic curtain uses class, heavyweight, luxurious fabrics mixed soundproofing stuff like mass-filled vinyl to dampen sound and decrease echo.
- Moving Blankets (Sure Max Heavy Duty):
Best Use: Good, compact, movable blankets can be used for some sound absorption when resources are less. Moving blankets have long been used for this purpose other than moving furniture. The dense, luxurious fabric of a blanket like the Sure Max Heavy Duty blankets can be used to absorb sound. The Sure Max blankets are made from plush cotton batting and polyester lining and weigh over 5 pounds each. They don’t have grommets for easy hanging, but the materials are pretty good for some low-sound absorbing system.
- Door Sealing Gasket & Sweep Kit:
Best Use: Foam gaskets are excellent, cheap materials for filling in space on door frames where sound loves to come in and out of rooms. Gaps between the door jam and door are the main paths for undesired noise to travel. Compressible foam gasket material helps seal up the gap and absorb some of the sounds. It’s just one end of the puzzle when it comes to soundproofing doors, however. A cheap, flimsy door is still going to transmit sound even with a gasket and door sweep, so problem areas may need acoustic curtains or blankets added to be useful.
How soundproofing materials can work for you:
The best soundproofing material will effectively block sound vibrations from being transferred in and out of your recording studio, so it must be made of excellent material. The smallest hole in soundproofing material will make it useless; as sound can find its way through the tiniest of cracks. You may be familiar with acoustical foam, which can absorb sounds within a room, and is very easy for a DIYer to use. Acoustical foam is rated A, B, or C according to its fire resistance, and some publicly announced fires have resulted from the use of low-grade acoustical foam. So, if you are planning to use it, don't scrimp on the cost. And make sure that you schedule a clear exit from the studio in case you have a fire because your fire-resistant acoustical foam will provide poisons if it should burn, and they are even more deadly than the fire itself! Soundproofing material, on the other hand, will block outside sound waves from entering your recording studio. The soundproofing material will be applied on the walls, ceiling, floor of the studio, and its doors and windows. It is also rated, but it's rated according to the extent to which it can lower sound decibels reaching the studio's interior.
