10 Ways to soundproof a room from outside noise

Are you tired of hearing your neighbor’s dog barking all night long? Or maybe the sound of traffic is keeping you up at night? Well, fear not because I’m here to share with you some tips on how to soundproof a room from outside noise!

Now, before we get started, let me tell you a little joke. What do you call a room that’s been soundproofed? A quiet room! (Okay, I know it’s not the funniest joke out there, but I promise the tips are much better!)

First off, let’s start with the basics. One of the easiest and most affordable ways to soundproof a room is by using weatherstripping tape. It’s a simple solution that can help block out noise from outside.

If you’re looking for something a bit more effective, then acoustic panels are the way to go. Not only do they look great, but they also absorb sound waves and reduce noise levels. Plus, they come in a variety of colors and patterns, so you can customize your soundproofing to match your decor.

But wait, there’s more! Have you heard of white noise machines? These bad boys emit a constant, soothing sound that can help mask outside noise and lull you to sleep. And if white noise isn’t your thing, there are plenty of other sound options to choose from, including rain, waves, and even jungle noises (because who doesn’t want to fall asleep to the sounds of a lion roaring?).

So there you have it, folks – 10 ways to soundproof a room from outside noise. With these tips, you’ll be able to create a peaceful and quiet environment in no time. And who knows, maybe you’ll even start sleeping like a baby (although I can’t promise that you’ll start drooling in your sleep, but hey, it’s worth a shot!).

How to Soundproof a Room from Outside Noise?

1. Fill up cracks and holes

Be incredibly meticulous. Even the smallest openings will allow noise to pass through, undermining any other soundproofing precautions you might take. Flexible caulk can be used to fill up cracks and gaps around sidings, doors, and windows.

Where pipes and wires enter the home, pack putty around them or spray expanding foam around them. Programs to lower noise levels in residences close to airports even advocate going to lengths like blocking off a mail slot and putting a mailbox in its place. These straightforward actions will provide the greatest value for your money.

2. Tighten existing doors and windows

Completely weatherstrip existing doors and windows on all four sides. Install a solid-core door instead of one with glass panels or a foam core since it will absorb more sound.

This will help dampen the incoming outdoor sound by blocking even the minimal air passages that might exist after closed doors and windows.

3. Using door seals and draft guards

A little crack in doors or windows allows the noise to enter through it. In this case, it is preferable to fill up the opening with a draft guard or door seal that adds insulation, limiting the annoying sound and any incoming hot or cold air, depending on the season.

4. Install high-quality storm windows

The best soundproofing windows have thick glass, strong frames, and thorough weather stripping. The gap between primary and storm windows should be at least three to four inches wide (3 to 4 is ideal).

Storm windows can be easily installed on double hung and glider windows, while one-piece, interior magnetic windows work well for crank-out casement windows. On all of your external doors, install sturdy, excellent storm doors.

5. Cover chimneys and vents

Chimneys and vents also make up one of the biggest air passages for your home. Add covers to chimneys to block direct noise pathways and replace open turbine roof vents with more robust, low-profile baffled vents. Covering a significant passage like this would help significantly dampen the sound entering.

6. Add Attic and wall insulation

If your walls are hollow, the sound can easily pass through them because of being less denser. Noise levels can be decreased using carefully installed fiberglass batt or blown-in insulation for the walls.

You can also add acoustics or double wall layers to get closer to the desired result of a noise-free home.

7. Give walls more bulk

Add mass in the form of drywall if one wall confronts a busy, noisy street. By hiding the sources of noise, trees, hedges, and fences offer psychological comfort.

But because they are light, they won’t be able to muffle much noise. Thus, adding a layer of drywall is an effective solution.

8. Repair creaky floorboards

A room with hardwood flooring looks beautiful and has a lot of charm, but if one or more planks are loose, the noise they make can be unbearable.

Although a new installation would be fantastic, the best option is to have your flooring restored by dependable professionals.

9. Hang drapes and tapestries

It’s not always necessary to fill your flat with large furniture and make it appear congested. You may also add thick, plush materials throughout your house, whether in the shape of tapestries, floor-to-ceiling curtains, or carpets. The noise from the environment may be reduced with the use of these fabrics.


10. Acoustic panels

You may easily add various forms of acoustic panels to the walls, such as boards or fabrics. This functions as a powerful weapon for deflecting any ambient noise that might be present.

Other materials that can be used for soundproofing include mass loaded vinyl and green glue. Mass loaded vinyl is a dense material that can be used to line walls, floors, and ceilings to reduce sound transmission. It typically costs around $0.50 to $3 per square foot. Green glue is a special adhesive that is used to layer soundproofing materials together to create a more effective barrier. It typically costs around $10 to $15 per tube.
