In this article, I will show you exactly how to stop sounds and voices from leaving a room. after reading this post you should have the knowledge to prevent out most of the noises from leaving and entering a room.

Most people prefer to keep most of their things private especially important conversations or would simply like to keep down music, video game sounds or even movies.

Unfortunately, sometimes that is not always possible due to most rooms are poorly soundproofed. Luckily there are things you can do right now that will prevent any sounds and noises from escaping the place.

1. Identify the Possible Places Sound Waves are Exiting

This step can save you a lot of time, effort and more because instead of trying to sound dampen the whole area, you can focus on the main source that allows the internal and external sounds and noises to go through.

Here is a list of common places you must check:

  • Door
  • Windows
  • Walls
  • Ceiling
  • Floor

In other to keep the sound in the room, finding and soundproofing these areas will have dramatic Results.

2. Use Soundproof Weatherstrips for the Door

This is one of the most basic but overlooked places that is exploited by noises and sounds due to the number of gaps a door has.

By sealing off the door gaps alone using sound dampening weatherstrips you can expect a significant decrease in the amount of noise coming off your room.

There are many ways to go about sound dampening the door, but my favorite one and by far the most cost-effective and efficient is using weatherstrips.

What I like about using the weatherstrips is the fact that they are super cheap, anyone can afford them and also easy use and that will save you tons of time when working on your DIY project.

Alternatively, you can use moving blankets on your door to help keep sound in a room but this isn’t a visually appealing solution but great if you are on a tight budget or a room that is in a hidden area.

3. Use Sound-absorbing Curtains

Now, this will depend on where the window of your room is located. Noise-reducing curtains are incredibly Amazing at absorbing some sounds and echoes in the room.

It is vital to understand that most sound dampening curtains will not soundproof your window 100% but you will see drastic results in the amount of noise and sounds escaping your room.

There are many sound dampening curtains but I recommend Nice Town Thermal Noise Reduction Drapes.

4. Soundproofing the wall.

This is crucial especially if you are also trying to get rid of low-frequency noises like bass or if you don’t want to be heard in the other rooms.

There are two ways to go about sound dampening the wall, which are:

  • Adding a Drywall using Green Glue
  • Acoustic foam panels

Adding Drywall using Green Glue.

This is by far the most effective of the two methods, what you are doing here is you are simply building an additional wall but instead of using bricks as you would normally do, You use drywall and green glue.

Green glue is a noise-proofing solution that is designed to sound dampen sounds and noises. It is very effective that is why it gets so much positive feedback around the world.

How this works is you will have to purchase enough drywall to cover the wall of your room and then use green glue to attach the drywall to the wall.

This is a bit costly compared to using acoustic foam panels, but also the most effective in my opinion.

Acoustic Foam Panels

This can work if you are on a tight budget and also the noise leaving your room is not too much. Acoustic foam panels won’t 100% soundproof the wall but greatly lower the sounds traveling through the wall and as a result of blocking out and in the noises.

The are many acoustic foams on the market and most of them are great but what I recommend for someone looking to block sound between rooms is to use Foamily Foam Panels.

5. Use Bass Traps

If the sounds you are trying to block contains some low-frequency sounds (Bass), then I think it’s a great idea to try bass traps to help absorb the bass noise.

Bass traps are often used to block out bass and are easy to use (All you have to do is attach each in every corner of your room)

What I like about bass traps is the fact that not only do they keep sound in a room but also great at preventing sound waves from bouncing up and down.

6. White Sounds

Yeah, I know this might not be the best alternative but most people like it (Including myself) that is the reason why I choose to include it.

White sounds are sounds that are typically played from a white noise machine, which are created to produce white noise that is relaxing and calm. you can try to play white noise sounds to create a quiet calm environment.

7. Add Carpet Rugs

You don’t already have a carpet in your room then adding one will do more good then harm especially if it is thick and great looking. Adding a bit of carpet will help noise-proof the floor and eliminate echoes, but this would be pretty much essential if you were trying to reduce noise from downstairs neighbors.

8. Get Indoor Sound Absorbing Plants

Another thing that you can do keep sound in a room and block it between rooms is to buy sound absorbing indoor plants, these are incredibly great and help create a nice quiet environment even if you leave in an apartment
