Home Sound Dampening: The Best Soundproof Insulation Methods

November 28, 2022

While sound is an undeniably important aspect of our existence, this type of energy can be a nuisance or hindrance when not controlled – and that's where soundproofing insulation comes in. Insulation helps block or reduce noise, and installing insulation for sound-dampening purposes is beneficial for any home, particularly if you live in high-traffic areas or apartment complexes.

Read on to learn how insulation can be used for soundproofing purposes and the types of insulation with the best soundproofing qualities.

How Does Insulation Help Reduce Noise?

Soundproofing is the process of reducing, eliminating, or blocking sound. It's a means of cutting down sound wave transmission through a building's fixtures, walls, or ceilings. According to Herriman on U.S. News, you should be aware of the different categories of sound control before you start soundproofing your home:

  • Absorption: An absorption is a complex form of reducing sound in a space where soundproofing is achieved by dissipating the energy of sound waves or acoustic energy. 
  • Damping: Damping is a form of absorption where oscillating sound waves undergo resonance with respect to the surfaces they hit. 
  • Isolation (Noise Blocking): Isolation blocks sound waves or acoustic energy from transferring through a barrier such as a wall. Soundproofing generally ties to isolation. 
  • Diffusion: Diffusion works by spreading sound evenly across a given space. Sound waves gradually get lost by being converted to kinetic or vibrational energy in the atoms of the room or medium. 

What Is the Best Insulation for Your Soundproofing Needs?

There are different materials for soundproofing and sound-dampening insulation. Even though you can't block sound entirely, you can significantly reduce the noise through soundproofing. However, remember that not all types of insulation will help reduce noise. If you want soundproofing insulation, fiberglass, cellulose, and spray foam insulation are the best and most common choices – and you can install them on your home's floors, ceilings, and walls. These kinds of insulation will best limit noise as they can reduce both outside noises and noises from one room to another or between different levels of your building. 

Types of Insulation for Soundproofing

Even though there are several ways you can achieve a good level of soundproofing, the most common methods include the following: 

Fiberglass Sound Insulation

Fiberglass is one of the most suggested solutions if you're struggling with noise in your home. Acoustic fiberglass is an amazing sound absorbent, especially when it comes to reducing echoes in a room. Fiberglass sound insulation combines rigidity and lightweight to allow for installation even in the tightest places.

Cellulose

Cellulose insulation reduces sound traveling between floors and through the walls. Blown-in cellulose insulation is used to create a tight fit in the stud cavity and seals around pipes and other outlets. It also makes a dense filling that acts as an excellent sound barrier.

Spray Foam Insulation

Spray foam insulation is also known as spray polyurethane foam and is used by professionals to insulate buildings or seal cracks and gaps. Besides preventing temperature fluctuations and being energy-efficient, it can also provide soundproofing. However, open-cell spray foam functions better at sound absorption than closed-cell spray foam. It reduces noise transfer between homes and rooms.
