Understanding the Basics of Soundproofing with Drywall
When it comes to creating a peaceful and quiet home environment, soundproofing is a crucial step.
Soundproofing is the process of reducing or eliminating the amount of sound that travels through walls, floors, and ceilings.
The goal of soundproofing is to create a quieter and more peaceful environment by blocking out unwanted noise.
While there are many ways to soundproof a room, one of the most effective and affordable solutions is by using drywall.
But can drywall really be used to soundproof a room?
Yes, drywall can be used to soundproof a room. When installed correctly, drywall can significantly reduce the amount of noise that travels through walls, floors, and ceilings.
It is a popular and effective material for soundproofing, and is also affordable and easy to install, making it a popular choice for DIY soundproofing projects.
How effective is drywall in soundproofing?
When it comes to soundproofing a room, it’s important to understand the Sound Transmission Class (STC) rating.
The STC rating measures how well a material or structure can block sound waves.
Regular drywall over wood studs has an STC score of 33, which means that it can block about one-third of the noise that travels through it.
However, using two sheets of drywall with insulation between them can significantly improve the STC rating.
This is because the insulation helps to absorb sound waves, while the double layer of drywall creates a more effective barrier.
With two sheets of drywall and fiberglass insulation between them, the STC rating can be increased to around 44, which is considered a good standard for regular homes.
It’s important to note that while the STC rating provides a good benchmark for soundproofing performance, it’s not the only factor to consider.
Other factors that can affect soundproofing include the frequency of the noise, the size of the room, and the type of activities that take place in the room.
Additionally, soundproofing is not a one-size-fits-all solution and may require customization based on the specific needs of the space.
Drywall is an effective material for soundproofing a room when installed correctly.
The effectiveness of drywall in soundproofing depends on various factors, such as the number of layers used, the thickness of the drywall, the insulation used between the walls, and the type of framing used.
When properly installed with multiple layers and insulation, drywall can significantly reduce the amount of noise that travels through walls, floors, and ceilings.
However, it’s important to note that complete soundproofing is difficult to achieve with any single material, including drywall.
To achieve the best results, it is often necessary to use a combination of soundproofing materials and techniques.

How to soundproof using drywall
If you’re looking to soundproof a room, using drywall is a great DIY solution that can be done with just a few tools and materials. Here’s how to soundproof using drywall:
Materials
- Drywall sheets
- Insulation
- Resilient channels or sound isolation clips
- Acoustical sealant or caulk
- Screws
- Screwdriver
- Utility knife
- Measuring tape
Steps:
- Measure the walls, ceiling, or floor that you want to soundproof. Calculate the amount of drywall and insulation you will need.
- Install the resilient channels or sound isolation clips to create an air gap between the drywall and the existing wall. This air gap helps to absorb sound waves and reduces sound transmission. Follow the manufacturer’s instructions for installation.
- Install the first layer of drywall onto the resilient channels or sound isolation clips. Use screws to attach the drywall to the channels or clips.
- Seal all the seams between the drywall sheets with acoustical sealant or caulk. This helps to prevent sound from leaking through the seams. Be sure to cover all gaps and holes, including around electrical outlets and light switches.
- Install insulation between the studs or joists. This helps to absorb sound waves and further reduce sound transmission. Follow the manufacturer’s instructions for installation.
- Install the second layer of drywall onto the first layer of drywall, making sure to attach it to the resilient channels or sound isolation clips. Use screws to attach the drywall to the channels or clips.
- Seal all the seams between the second layer of drywall sheets with acoustical sealant or caulk.
- Finish the drywall as desired by sanding and painting.
Following these steps will help you soundproof a room using drywall.
However, it’s important to note that the effectiveness of your soundproofing will depend on several factors, including the thickness of the drywall, the insulation used, and the type of framing used.
For best results, consider consulting with a professional or doing additional research to ensure that you are soundproofing your space effectively.
Best Practices for Soundproofing with Drywall
To effectively soundproof a room with drywall, there are a few best practices to keep in mind:
Multiple Layers
To achieve the best results, it’s recommended to use multiple layers of drywall. This will help to reduce the amount of sound that can penetrate through the walls.
While drywall is a popular material for soundproofing, a single layer may not be enough to achieve complete soundproofing.
For optimal soundproofing, it is recommended to use multiple layers of drywall.
The reason for using multiple layers of drywall is that each layer helps to block sound waves from passing through.
When sound waves hit the first layer of drywall, some of the energy is absorbed, while the rest passes through.
The second layer of drywall helps to absorb more energy, and the third layer absorbs even more.
With each additional layer of drywall, the amount of sound that can pass through is reduced.
It is important to note that simply adding more layers of drywall does not necessarily mean better soundproofing.
The best results are achieved when the layers are separated by an air gap, which helps to reduce sound transmission.
To create an effective soundproof barrier, it is recommended to use at least two layers of drywall with an air gap between them.
Resilient channels & sound isolation clips
The soundproofing effect can be achieved by installing a resilient channel or sound isolation clips between the layers.
Resilient channels are metal channels that are installed horizontally between the drywall and the studs.
They create an air gap between the drywall and the studs, which helps to reduce sound transmission.
Sound isolation clips are similar to resilient channels, but they are installed vertically between the drywall layers. They also create an air gap and help to reduce sound transmission.
Seal all the seams
It’s important to seal all seams between the drywall sheets to prevent sound from leaking through. This can be done using acoustical caulk or sealant.
Sealing the seams between the drywall sheets is a crucial step in soundproofing a room with drywall. If the seams are not properly sealed, sound can leak through the gaps, reducing the effectiveness of the soundproofing.
To seal the seams, you can use acoustical caulk or sealant. Acoustical sealant is specially designed to be used in soundproofing applications and can effectively seal gaps and cracks, providing airtight and watertight seals.
When applying acoustical sealant, it’s important to apply it generously and ensure that it fills all gaps and cracks completely.
Use a caulking gun or a trowel to apply the sealant, and make sure to smooth it out to create a consistent seal.
It’s also important to note that traditional drywall joint compound is not a suitable substitute for acoustical sealant.
While joint compound can be used to finish drywall seams, it is not designed to be used as a sealant and may not effectively block sound waves.
In addition to sealing the seams between the drywall sheets, it’s also important to seal any gaps around electrical outlets, light switches, and other fixtures.
Use foam gaskets or acoustic putty pads to seal these gaps, as they can be a significant source of sound leakage.
By properly sealing all the seams and gaps, you can help ensure that your soundproofing project is as effective as possible. Remember to take your time and be thorough when sealing the seams to achieve the best results.
Use Mass-Loaded Vinyl
To further improve the soundproofing performance of your drywall, consider adding a layer of mass-loaded vinyl between the drywall sheets.
This material is specifically designed to absorb and block sound.
Mass-Loaded Vinyl (MLV) is a specialized material that is often used in soundproofing applications.
MLV is a dense, flexible material that is designed to absorb and block sound waves, making it an excellent choice for improving the soundproofing performance of drywall.
One of the primary advantages of MLV is its high mass. Because it is denser than most other materials, MLV is very effective at blocking sound waves.
When used in combination with drywall, it can significantly reduce the amount of noise that travels through walls, floors, and ceilings.
MLV is also a flexible material, which makes it easy to install. It can be cut to size and applied directly to walls, ceilings, or floors using adhesive or screws.
It can also be used in combination with drywall, with one layer of MLV sandwiched between two layers of drywall.
In addition to its soundproofing capabilities, MLV is also fire-resistant and waterproof, making it a safe and durable choice for soundproofing applications.
However, it’s important to note that MLV can be expensive and may not be necessary for all soundproofing projects.
For most residential applications, using two layers of drywall with insulation between them will provide adequate soundproofing performance.
If you are dealing with particularly loud or persistent noise, or if you are soundproofing a commercial or industrial space, MLV may be a good investment.
Tips for a Successful Soundproofing Project
While soundproofing with drywall is a relatively simple process, there are a few tips that can help ensure a successful project:
- Plan Ahead: Before you begin your soundproofing project, make sure to carefully plan out the materials and tools you will need.
