15 Best Types of Soundproofing Materials Explained

Whether you’re trying to block out the sounds from the city or make an office quieter, selecting the right soundproofing materials is one of the most important things to get right.

Here’s our list of some of the best soundproofing materials that you shouldn’t forget to consider.

Soundproofing vs. Sound Absorption: Which Am I Looking For?

Before we touch on our favorite soundproofing materials, we need to address the difference between soundproofing and sound absorption. The reason is, understanding the difference helps you select the materials that will help you. Another reason is, many individuals often—incorrectly—consider soundproofing materials and sound absorption materials the same thing.

Here’s the difference:

Soundproofing is the process of preventing sound from entering or leaving a room. It is commonly used in recording studios, home theaters, and offices in order to create a quieter environment. 

Sound absorption, on the other hand, involves reducing sound reflections within a space, which improves sound quality in places like theaters, auditoriums, and open offices.

15 Types of Soundproofing Materials

Now that we know the difference between soundproofing and sound absorption, let's take a look at some of the best materials available to make your room quieter. 

We’ll even highlight their unique applications, benefits, and drawbacks.

1. Mass Loaded Vinyl (MLV)

Mass Loaded Vinyl stands out as a top choice for soundproofing. It’s a dense, flexible material perfect for walls, floors, and ceilings. It’s high density effectively blocks sound transmission, which makes it a versatile solution for various spaces. However, its weight can make installation a bit challenging—and it tends to be on the pricier side.

2. Soundproof Paint

Soundproof paint, sometimes referred to as sound-deadening paint, is paint that works to minimize the transmission of sound. 

As a paint, it can be applied either by means of a roller or sprayed on. Thicker layers of pain will result in better soundproofing properties. While simple and affordable, even thick layers just do not have a great deal of mass. Soundproof paint helps, but is not the most effective option for a sound proofing material.

3. Acoustic Panels

Acoustic panels are ideal for enhancing sound quality in offices, studios, and home theaters. They absorb sound reflections, reduce echo, and improve clarity. 

They also remain available in various aesthetic options—all of which are lightweight and easy-to-install. 

Just keep in mind: while excellent for sound absorption, they are not designed for complete soundproofing.

4. Acoustic Foam

Acoustic foam sheets are ideal for sound absorption. Acoustic foam is sold under many brand names and is available in many different colors, shapes and sizes. 

It is great for minimizing foam leakage and improving the sound quality in a room. However, it does not perform well at preventing the transfer of sound from room to room.

5. Fiberglass Insulation

Fiberglass insulation is a dual-purpose material that provides both thermal and sound insulation. Commonly used inside walls, ceilings, and floors, it is affordable and widely available. Although it provides soundproofing qualities, installing fiberglass insulation does require the use of protective gear, and it's not the most eco-friendly option.

6. Green Glue Compound

Green Glue is a polymeric compound that offers a simple yet effective way to reduce sound transmission—because it’s applied between drywall layers.

It's cost-efficient and easy to use, though it requires time to cure and works best when combined with other soundproofing materials.

7. Soundproof Drywall

For those seeking a straightforward solution, soundproof drywall is an excellent option. It’s a dense material used in walls and ceilings to provide an effective barrier against sound. Although it installs just like regular drywall, it is heavier and more expensive, which are the primary drawbacks.

8. Carpet and Padding

Carpet and padding is a practical way to reduce noise on floors and stairs. These materials not only dampen sound, they also add comfort. Carpet is available in various styles to provide both aesthetic and functional benefits. However, it is limited to floor use and can wear out over time.

9. Dense Boards

Adding mass to the walls is an effective method to reduce sound transmission. Plywood, oriented strand board, and other dense boards are good options for adding mass at relatively low cost. While the increased mass helps with soundproofing, it is important to make sure that the walls can support the additional load. 

Metal Form Manufacturing’s Soundproofing Products

Metal Form Manufacturing also has a variety of sound absorbing and soundproofing materials and products.

Here’s a few:

10. Sound Attenuators

Sound attenuators are available in round and rectangular shapes. They are expertly crafted to significantly reduce noise in HVAC systems, to ensure a quieter and more comfortable environment. Customizable to suit specific needs, sound attenuators offer high performance, which makes them an ideal choice for any HVAC application.

11. Acoustical Louvers

Acoustical louvers strike a perfect balance between ventilation and sound control. Whether you opt for the standard or high-performance versions, acoustical louvers are built to last and deliver excellent noise reduction. They are perfect for settings where maintaining airflow without compromising on soundproofing is crucial, though their installation can be a bit complex.

12. Transfer Silencers

Transfer silencers are another standout product that is designed to minimize noise transmission through ducts.

Available in duct-mounted and plenum-mounted types, transfer silencers are highly effective in reducing unwanted noise, which makes them versatile solutions for various applications. While they can be bulky, their high attenuation capabilities make them well worth the effort.

13. Acoustical Panels

For those looking to enhance sound absorption, acoustical panels are a superb option. The acoustic panels come in fabric-wrapped and perforated metal varieties that not only absorb sound effectively, they also add a touch of aesthetic appeal to any space.
