Soundproofing Walls Without Removing Drywall in 7 Easy Steps

This article will show you how soundproofing walls without removing drywall works and whether it’s a viable DIY soundproofing project that anyone should undertake.

In most cases, when soundproofing a wall against bass noise, it’s always recommended you remove the existing layer of drywall to allow you to add some soundproofing materials.

Unfortunately, this process may not be viable for those on a budget or anyone living in a rented unit.

Whatever reason could prevent removing the drywall, just know that soundproofing walls without removing drywall is still much possible.

How Soundproofing Walls Without Removing Drywall Works?

When it comes to soundproofing, it’s important to always determine the type of sound you’re dealing with in the first place.

As I’ve always stated, there are two types of sounds we always aim to block in any soundproofing project.

There are airborne and impact sounds.

Impact sounds travel through solids while airborne through the air (Source)

Structure-borne noise (impact noise) is transmitted in the form of vibration. For example, neighbors’ stomping/ footfalls or bass vibrations fall in this case.

On the other hand, airborne noise travels through air- for example, the noise coming from neighbors’ yards is airborne.

Now that you’re familiar with the two main types of sound let’s have a look at how soundproofing walls without removing drywall works.

1. Talk to Your Neighbors

I’m guessing you’ve probably tried this method and failed.

However, if you haven’t, why not first have a chat with them?

Your neighbors could be considerate people, and you’ll be surprised they’re not aware they’re being noisy.

If this method fails, you have two options: annoy them (here’s my guide on how to annoy noisy neighbors) or soundproof your house.

2. Seal all the gaps and cracks

The most important step would be to seal all the cracks and gaps on the existing walls.

Sealing these gaps and cracks will help prevent airborne sounds from traveling across the walls.

The best approach to sealing is using a product known as green glue soundproofing sealant.

This product is specifically designed for soundproofing against both airborne and impact noise.

It simply converts sound energy into heat energy- the heat generated in this case is negligible.

3. Installing Acoustic Foam Panels

Acoustic foam panels are my favorite when it comes to soundproofing against airborne and impact noises.

They help in soundproofing and help in absorbing echoes and reverberations in a room, resulting in high clear audios from your stereo.

For these reasons, you will find acoustic foam panels in recording studios, drum halls, cinema halls, theaters, and nightclubs.

Acoustic foam panels come in different colors and thicknesses ranging from 1″ to 4″.

If you’re dealing with the two types of noises mentioned above, I’d recommend you pick the thickest one for maximum effectiveness.

They are easy to install even though they require precise installation for the best results.

4. Mass Loaded Vinyl

Mass-loaded vinyl is a flexible, affordable, and effective soundproofing product.

Like acoustic foam panels discussed above, this product is great for use in movie theaters, studio projects, and residential applications.

Also known as Limp Mass Barrier, this product comprises of two main ingredients, which include:

Vinyl gives the product its flexibility; Limpness, a high mass element that gives the product soundproofing characteristics.

It’s a nontoxic material and often used in soundproofing projects where a layer of drywall is added.

Hang it over your existing layer of drywall to help in sound absorption.

Unlike acoustic foam, MLV comes in gray or black color only.

However, you can change the color- simply buy a latex paint of your desired color, paint, and voila!

5. Soundproofing Curtains

Soundproofing curtains are not your typical curtains.

They are made using thick and dense material, hence reducing the amount of noise that comes into your house.

Additionally, these curtains are also known as blackout curtains as they completely block out ultraviolet sun rays.

However, it’s important to note that these curtains won’t magically make sounds disappear.

These curtains absorb significant amounts of incoming outside noise, reducing the amount of noise that makes it into your house.

Curtains are highly effective in reducing high-frequency noise and not low-frequency sounds like a bass.

You can expect up to 75% airborne sound absorption from the noise reduction curtains.

6. Rearranging Furniture

One of the cheapest and yet effective soundproofing walls without removing drywall involves rearranging the furniture in your house.

The rule is simple.

First, inspect the source where the noise is coming through.

Secondly, move your heavy furniture like bookshelves or portable closets next to the wall.

You can stack up the bookshelves with books or the closets with clothes to ensure that there’s more mass which equals to better sound reduction.

This method is highly effective in dealing with both airborne and impact noises.

Rearranging the furniture is also another method of soundproofing a house with household items.

7. Acoustical Wallpaper

You’ve probably heard of wallpapers but never heard about soundproofing wallpapers.

Well, acoustical wallpapers help in absorbing echoes and reverberations in a room.

They also help in reducing high-frequency sound but least reliable when it comes to impact sounds.

Acoustic wallpapers are made from acoustic materials and have multiple layers that help achieve maximum sound reduction.

On Soundproofing Walls Without Removing Drywall

Soundproofing walls without removing drywall doesn’t have to be an expensive or time-consuming project.

Above are simple and easy to implement methods that will reduce noise levels in your house to manageable levels.

However, don’t forget that proper sound reduction requires you to approach all the areas in your home, including soundproofing the ceilings, doors, windows, and the floor as well.
