Don’t know the first thing about soundproofing? No need to worry – we got your backs. In this article, we will teach you how to soundproof a wall in simple steps, DIY style! Without further ado, let’s get started!

Things you need to consider before starting your project

Now that you learnt how beneficial soundproofing your walls is for you, you must be excited to move on to the next step of the process. However, you can’t head out and start soundproofing your walls immediately! There are a few things that you have to consider before you start your DIY project such as timeframe, costs, etc. 

1. The level of Sound Proofing that You Need

You will have to figure out the level of soundproofing you require. For instance, if you are living in a noisy, industrial area the level of soundproofing you need will differ if you are only looking to block the airborne sound of noisy kids playing in the neighbourhood. Once you decide this, you will be able to see how much time you need, what kind of tools and materials you will have to get and everything else that needs to be done.

2. Know the Time Constraints

When you are starting any project, you need to take a look at the time constraints. Will you be working on the project every day of the week or will you work for a couple of hours after you leave your office? Are you thinking about making it a weekend project only? Set the time limit and then divide all the steps of the task accordingly.

3. Make a Budget

Have only a few hundred pounds to spare? Don’t worry – you can plan your project according to your budget. Higher price tags don’t always mean high quality! Make a budget and note down your requirements.  When you are out buying soundproofing equipment, compare your requirements, your budget constraints, and the features of the product you are looking to buy.

4. Check Your Walls

The next thing that you need to do is check your walls for gaps and weak points. Treat a soundproofing project similar to a waterproofing one – it will be as good as the weakest point!  For instance, if you roll your car window down completely, you will hear a lot of noise. 

As you roll it back up slowly, the noise level drops. If you leave it open slightly, the noise will still penetrate. Thus, it is important to look for weak links and gaps in your walls from where excessive noise can travel. Are there any gaps in the door frames and the walls? Fixing holes in your plasterboards and drywalls is a crucial step!

How to soundproof a wall step-by-step

Whether it is construction workers or noisy neighbourhood kids, you are going to face the issue of noise. What you should do is take the necessary measures to lessen the noise as much as you can. There are two approaches that you can take:

  1. You can take your wall apart and add soundproofing products such as acoustic foam panels, mass loaded vinyl, etc.
  2. You can soundproof your existing wall.

If you are building an entirely new wall, we suggest that you use double-stud walls or staggered studs along with sound clips & resilient channels. These will stop noise from travelling between walls. 

Ready? Here’s a step-by-step guide you can follow for easy wall soundproofing solutions!

The main steps are as follows:

  1. Figure out where the noise is coming from.
  2. Find the studs on your wall and mark them with a pencil or chalk.
  3. Fill the wall space with the help of soundproofing materials.
  4. Install soundproofing system as well as acoustic panels.
  5. Seal the edges and seams with sealant.

Tools that You Will Need to Block Sound

  • Utility Knife
  • Dust Mask

Materials that You Will Need for Sound Reduction

  • Plywood
  • Drywall
  • Acoustic Dampening Adhesive
  • Door Sweeps
  • Electrical Box Extenders
  • Insulating Material (Fiberglass)
  • Silicone Caulk
  • Work Gloves


1. Sound Proofing the Electrical Boxes

Electrical boxes are installed within the walls and can cause sound waves to leak from one room to the other. Turn off the power from the main panel. Seal the electrical boxes by using silicone or acoustical caulk

If there are any openings or holes in the boxes, seal them as well. You can buy the sealant from your local store or order it online.

2. Insulating the Walls

The next step is to insulate the brick walls. Fill the stud cavities in your walls with fibreglass batts. Ensure that there are no open gaps between the cavities. If there are any electrical cables or pipes, cut the insulation with the help of a utility knife to see that it fits squarely around them.

When you are working with fibreglass, it is better that you wear a dust mask as well as protective eye gear.

3. Attach the Drywall

Once you have added the insulating material, it is time to screw in the drywall. Attach the drywall with the channels and not into the studs. Keep the drywall sheets running vertically on the walls while on the ceiling, keep them perpendicular to the channel.

Add a layer of acoustic panelling to the existing drywall to reduce sound if you don’t want to take the existing one apart.

4. Seal the Edges

If there is any gap between the drywall and the floor, seal it with silicone caulk or acoustic sealant. Also, seal the gaps and cracks in the corners where one wall meets the other.

If you are looking to soundproof an existing wall, then you can do that as well. Here are the steps to do that.

Add Soundproofing Material to the Walls

Simply add materials like blankets, sheets, carpets, etc. to block out excessive impact noise. It will not block out all the airborne noise, but will definitely act as a barrier and will provide sound insulation

Use Soundproofing Sealant

Sound can easily escape from the tiniest spaces and cracks. Get a tube of sealant that you can use to seal any visible cracks and holes in the walls. This will make a huge difference in case your room has plenty of edges and cracks that let sound in. 

Moreover, you need to fix all the sound leaks such as loose floorboards, window gaps, plasterboards, etc. Instead of taking the whole wall apart, simply focus on the small part of the wall from where you know the sound is escaping. 

What are the benefits of soundproofing a wall

Want to know more about the benefits of soundproofing a wall? Well, there are plenty of them. If you soundproof a wall facing the road or adjacent to a noisy construction site, the quality of life at your home will certainly change for the better. Here are a few reasons why you should go with soundproofing.

1. Privacy

Privacy is hard to come by these days but unlike your social lives, you can actually maintain a semblance of privacy by soundproofing your walls to prevent voice leaks. You will ensure that your neighbour’s nose stays where it belongs – out of your business! Moreover, it will maintain privacy within the house as well. You can carry out your daily activities without disturbing other members of your house if your walls have a sound barrier.

2. Health & Safety

We all have read about noise pollution, right? Just as a lot of noise is not good for the environment, excess noise is bad for the human body as well. Research and studies have linked the prevalence of various cardiovascular diseases such as high blood pressure, stroke, etc. 

Plus, exposure to noise causes irritability, adds to stress, causes anxiety, and has other deteriorating effects on the human body. Being exposed to unwanted, loud sounds can lead to hearing impairment as well. Nothing tops your health, right?

3. Comfort & Peace

Want to watch a football game? Looking forward to the newly released action movie but you don’t want to disturb other members of your home? Soundproofing your walls will ensure that you have fun without disturbing anyone. Similarly, if you are sleeping after a long, hectic day at work no one will disturb your peace, both inside and outside the walls of your home!

4. Improve Communication

Have you ever tried to have a conversation in a noisy restaurant? Found it hard to communicate your words and feelings, right? In both public and residential areas, excessive noise hinders communication between people.

Imagine trying to talk to your partner about your feelings with a noisy neighbour blasting loud music next door. By soundproofing your walls, you will ensure that there is no confusion and misunderstanding since you can communicate properly.

5. Policy & Regulations

To deal with noise issues and noise problems, several countries have enacted legislation. In some jurisdictions, there is strict enforcement of rules and regulations for the residents regarding soundproofing. These rules will ensure that you stay away from excessive noise, as well as stay on the right side of the law!
