Best Soundproofing Material

Best Soundproofing Material: A Review and Buying Guide

Soundproofing material may sound like something only musicians in a music studio need, but it can actually be used for a number of useful purposes.

Muting the sounds from a noisy washer and dryer in the next room, absorbing sounds from traffic on a busy street, and even dulling the roar from planes and trains are just some of the reasons to use soundproofing material.

Or perhaps you live in an apartment building with a committed musician as your neighbor, and he prefers to practice at 3 in the morning.

Whatever your needs are, there are various types of soundproofing material that can help reduce unwanted noise. There’s even soundproof paint that can help eliminate annoying noise.

In a hurry ? Here are our top picks

In this guide, we go over five different types of soundproofing material that can help reduce the transmission of sound. Each of these materials can be easily found, purchased, and even installed on your own (though you might need a friend or two).

1. Soundsulate ½ lb Mass Loaded Vinyl

Mass Loaded Vinyl, or MLV, is one of the most used and trusted materials when it comes to soundproofing. It’s thin, so won’t take up much space, and it’s dense, making it far more effective at reducing sound than some other more porous materials.

Typically applied over a wall stud, joists, or suspended ceilings, it’s extremely flexible, making it a perfect material to wrap around noise-producing ducts, machines, and other equipment. The denseness of the MLV makes it a heavy-duty barrier for reducing or eliminating unwanted sound.

The most common sizes of Sounsulate’s ½ lb MLV are 4’ x 25’ (100 square feet), 4’ x 50’ (200 square feet), and 4’ x 505’ (2020 square feet).

Pros

Pros
  • Can be cut to fit over most any area or equipment
  • A strong material that is durable
  • Flexible, making it easy to curve around walls, doors, or other surfaces
  • Availability in a larger size means you can use one sheet for a variety of projects

Cons

Cons
  • Only an STC (Sound Transmission Class) Rating of 20, which is on the low end
  • May not provide best sound dampening unless used with or between other materials, such as layers of drywall
  • Like water, noise transmission can seep through cracks, so it may not work perfectly if it’s improperly sealed
  • Installation process can be difficult due to the weight of the material

The Soundsulate ½ lb Mass Loaded Vinyl can handle nearly any soundproofing project you can imagine. Its dense material provides a noticeable reduction in sound energy, though it works particularly well when paired with other soundproofing materials, such as soundproof drywall.

It’s best for those who need a minimal sound dampening material, or who are going to use it as a soundproofing insulation between a layer of drywall. For larger projects such as this, professional installation is probably a better choice than trying to install it on your own.

2. SoundproofingMLV 1 lb Mass Loaded Vinyl

SoundproofingMLV’s 1 lb Mass Loaded Vinyl is a multi-purpose soundproofing product that can be used just as easily in a living space or an office space to cut down transmission of sound.

  • As with most MLV, it is heavy and may require professional installation, or at least a friend or two to help you install it

3. SoundproofingMLV 1.5 lb Mass Loaded Vinyl 

The 1.5 lb Mass Loaded Vinyl by SoundproofingMLV is the heavier duty cousin to its 1 lb MLV. This provides an even more effective sound barrier, though may make installation more cumbersome (though the installation instructions included help a ton).

As an acoustic foam panel, this type of product does not block sound; it merely absorbs it. This makes it best for rooms where sound quality is optimal, such as music studios or home theater rooms.

Things to Know Before You Buy: The Best Soundproofing Material

Sound Absorption vs. Soundproofing

One of the most common misconceptions about creating a soundproofing system is that all materials act in the same way.

Many people have confused a soundproofing material and a sound-absorbing material, which have caused issues. It’s important to know the difference between the two in order to purchase the one which will work best for your needs.

Soundproofing Options

Materials such as MLV, or Mass Loaded Vinyl, are sound dampening materials that reflect sound transmission. As such, it is best used as a building material between drywall or on an exterior wall.

If the goal is to eliminate or reduce noise, a soundproofing material is best for this type of job. MLV can be cut, shaped, and layered to cover a variety of noise producing objects. It can also be placed inside of a wall to cut down on noise getting through.

Sound Absorption Options

Sound absorption materials, on the other hand, are designed to create a cleaner acoustic quality of a space. They do this by eliminating reverberations of sound off of objects such as walls.

Sound-absorbing material does not block sound as a soundproofing material does; it merely absorbs excess sound vibrations. This can make it an effective soundproofing option if used correctly, but the main purpose is not so much to soundproof as to improve the quality of sound.

Conclusion on the Best Soundproofing Material

The first four products offer a variety of Mass Loaded Vinyls in different weights, thickness, and sizes. Mass Loaded Vinyl is an effective soundproofing material that’s best when used in combination with drywall or other sound-reducing materials.

The last product is a sound-absorption material; a heavy blanket that can be hung to reduce or eliminate the excess vibrations of sound. It’s best when wanting to improve audio quality, effective in music rooms or home theater rooms.

Whether you’re looking for the best soundproofing material or sound absorbing material, this list of products offers both. You should find an effective soundproofing option here no matter your needs.
