Types of Soundproofing Materials

Different materials have different effects on sound. Your soundproofing needs will depend on your goals. For example, if you’re a guitar player who likes to rock out in the middle of the night, you’ll want to focus on keeping sound in, and you’ll also want to improve the acoustics in the room. If you are the neighbor of a guitar player, you’ll want to keep sound from entering your bedroom while you try to sleep. Let’s look at the features, benefits and uses of the soundproofing materials we offer at Soundproof Cow to help you find the best solution for your noise-reduction needs.

Different Types of Sound Dampening Materials

1. Dampening and Deadening Materials

Dampening and deadening materials are often used in situations where extreme temperatures or limited space is an issue. Sound deadening works by reducing vibrations to make a space quieter. They are commonly used to stop rattling in cars for a quiet ride with improved stereo sound.

Materials for sound deadening also help reduce distracting noise exposure in construction. You might install a sound dampening material inside an engine compartment to decrease the noise for heavy equipment operators. One study from 2016 confirmed that the use of sound dampening mats substantially reduced the engine noise reaching the operator. It proved to be an easy-to-install and affordable solution to a common problem.

At Soundproof Cow, we offer a variety of sound deadening materials to fit in awkwardly-shaped spaces like appliance interiors or to create a smooth finished look inside a trunk. Whether you want to paint a surface or install a customizable peel-and-stick material, our sound dampening materials are udderly amazing. Our products include:

The following products create an impenetrable seal against sound so that you can block out noisy neighbors or traffic on the other side of the door:

  • Quiet Door perimeter seal: A perimeter seal forms a tight fit around the perimeter of a new or existing door. Made of heavy-duty aluminum framing and silicone, these seals can be adjusted or trimmed to fit your needs. Our adjustable perimeter seal allows you to make it like new with a couple turns of a screwdriver once it starts to wear.
  • Quiet Door sweep: Our door sweeps push down firmly against the threshold of a door. Our sweep is built to treat standard doors that are between 28 inches and 36 inches wide. However, you can trim the material to fit any sized door. Or, if your door is much wider, give us a shout, and we’ll construct a custom door sweep for you. Our automatic door sweep pushes tightly against the threshold as the door closes.

We also offer Quiet Door soundproofing kits which include soundproofing composite, perimeter seals, door sweeps and sound sealant for protection against noise.

Door seals and sweeps can be used just about anywhere there’s a door and a person who wants peace or privacy. However, here are some places that can make good use of soundproof doors:

  • Apartments
  • Band practice rooms
  • Broadcast studios
  • Computer and equipment rooms

7. Soundproofing Barriers

You may find a soundproofing barrier is essential to keeping the peace around your property. From blocking out airport noise to minimizing hum from your air conditioner, we have large and small noise-reducing materials capable of handling all types and sizes of annoyance.

soundproof barriers use vinyl, foam or fiberglass layers

Soundproof barriers use vinyl, foam or fiberglass layers to block and deflect sound. They are usually flexible and feature a peel-and-stick backing so they can easily fit just about anywhere. We offer the following products to block sound in various situations:

  • Fiberglass composite: Our soundproof fiberglass composite combines a fiberglass blanket with Quiet Barrier™ high-performance soundproofing material and a reinforced polyester film facing. Only 1-inch thick, these sound panels are easy to use just about anywhere you need to reduce noise. For example, you can adhere them to noisy machinery or hang panels on the wall using one of our soundproofing installation products. Fiberglass composite is a highly flexible, powerful soundproofing solution.
  • Foam composite: Our foam composite soundproof barriers contain at least one layer of Quiet Barrier soundproofing material and one layer of acoustic-grade polyurethane foam. The Quiet Barrier layer works to block sound while the foam separates the barrier from the wall to prevent impact noise. The result is optimum sound control. We offer a range of foam composite products from a wrap you can use to soundproof pipes to easy peel-and-stick panels.
  • Temporary barrier: If you need a temporary noise control solution, a temporary barrier may be the answer you’re looking for. Temporary barriers are acoustic quilts you can simply hang or lay down wherever you need soundproofing. Made of fiberglass and a nonporous vinyl covering, you can use temporary barriers as a sound-blocking curtain or to cover loud equipment. It’s a cost-effective way to solve noise issues in all kinds of situations.
  • Mass loaded vinyl (MLV) barrier: MLV barriers are composed of salts, sands and metal particles to give them highly effective noise-reduction power. MLV barriers add mass to an area to block sound waves from penetrating through walls and ceilings. It’s a popular way to soundproof music studios. MLV barriers are safe to use and easy to apply between drywall layers or other building materials.

Soundproofing barriers are excellent options when you need to keep sound in or keep sound out. You might use a soundproofing barrier in:

  • Cars
  • Firing ranges
  • Home theaters

At Soundproof Cow, we’re happy to talk about what solution would work best for your project or particular need.

Our Premium Sound Dampening & Deadening Materials:

At Soundproof Cow, we know typical acoustic materials don’t work well in every space. Sometimes there are special situations that require different sizing or adhesion. Silent Running SR-500 is one of our premier products for tight and awkward locations, particularly for appliances and machinery. This paint-based material is a permanent installation, applied directly to any surface with a traditional paint roller or spray gun. Once dry, the coating controls noise by converting sounds and vibration to heat.

Silent Running SR-500 is incredibly versatile. You can apply it to any number of surfaces, including metals, plastics, glass and even wood! Plus, it can resist both extreme cold and heat, making it a superb resource in industrial noise pollution control. As is true for most of our products, there’s little mess involved in application or cleanup. The water-based solution cleans up easily with soap and water. When dry, it leaves a coating that will shrink and expand with the surface it’s adhered to. Even in extreme environments this material will not ship or crack.

RoadBlockR™ is designed specifically for automotive applications. Thin, capable of withstanding extreme conditions and easy to apply, RoadBlockR™ is adept at controlling sounds from both inside and outside of a moving vehicle. It’s also proven to be successful in other applications. From industrial to residential applications, RoadBlockR™ provides protection from noise pollution in a myriad of situations. Use it as intended to create a crystal clear stereo sound as you block out the hum of the road or dampen noise from a commercial air conditioning unit.

Finally, we carry an extremely effective vibration and acoustic dampening material called Vibra Block®. The industrial-grade material comes in all shapes and sizes. It’s applied directly to the surface of machinery using our convenient, mess-free peel-and-stick adhesive. This is the most powerful anti-vibration application on the market and one of our favorite products here at Soundproof Cow. Order today to see its performance first-hand.

Benefits of Soundproofing Materials

Soundproofing materials keep noise from escaping, and they block noise from entering. Noise reduction has many benefits for everyone it affects. For example, soundproofing materials provide a quiet space for learning. Whether you’re in an office, library or classroom, noise affects how you focus and learn. One study found that students in a standard or noisy environment did not learn as well as students in a quiet school.

Noise reduction also reduces stress. When you are less stressed, your memory and your overall health improve. Those are just a few of the benefits. Soundproofing materials:

  • Provide privacy
  • Provide simple solutions
  • Are easy to install
  • Are highly versatile and affordable
  • Reduce energy costs
  • Improve sound quality
  • Make everyone happier

What to Consider When Choosing Soundproofing Materials

If you are ready to enjoy sweet silence or turn up the bass, you’re probably wondering where to begin. After all, there are so many soundproofing materials to choose from. Before you shop, you’ll need to ask yourself the following two questions:

  • What type of product do I need: If you wish to keep noise from entering, you want a soundproofing material that blocks noise and keeps it from traveling through the walls, doors, and ceilings. Any items mentioned in this post are designed to block sound. If you are interested in reducing echo and improving the sound quality of a space, a sound absorbing material is the way to go.
  • Where or what am I trying to soundproof: Consider what you are trying to soundproof as this will affect your decision. For example, if you need to quiet noisy pipes, you’ll want a flexible material that you can trim and wrap around pipes. If you’re trying to block sound from slipping under the door, you’ll need to seal up gaps where sound can escape.
