How To Soundproof A Room From Inside Noise[DIY]

If you are willing to learn how to soundproof a room from inside noise that means you are performing some work inside the room like recording or something. And you don’t want the sound to go out.

Also if you’re recording any music inside the room, you don’t want it to echo inside the room because it will sound very wired really. So, here I will tell the best steps to soundproof a room from outside so that the noise won’t go outside and the sound won’t be echoed inside the room.

How To Soundproof A Room From Inside Noise

I will start from the most important ways to the least important ways to soundproof a room from inside.

Place Furniture Inside The Room

items of furniture

Placing the furniture inside the room is the most important thing to do if you don’t want to reflect the sound and echo. You can use simple tables, chairs as an item of furniture. It is better to use wooden items because they are good sound absorbers than steel or iron.

So, when you place items of furniture inside the room, less sound will reach the walls and bounce back and create an echo. So, it is most important to place items of furniture inside the room first.

Soundproof Floors

Soundproofing the floors of an apartment or room is one of the most important steps to soundproof a room from inside.

There are many ways to soundproof a floor and some of the best ways are:

  • Use rugs: The rugs will absorb the vibration of the sound and won’t let it reflect back into the air and in this way, the sound won’t reach the downstairs also. Better to use the high pile rugs, but low pile rugs are also ok.
  • Use Rubber Sound Killing Mattress: The rubber is the best material to absorb the sound because that is a high-density material. So, if you can use a rubber mattress on your floor, it would be better.
  • Mass Loading Vinyl(MLV): MLV is one of the most used soundproofing materials. If you want to make your floor highly soundproof then only I will suggest you go for this. Else I won’t suggest because it doesn’t look that nice on the floor.

Soundproofing The Walls

After you soundproof the floors, the wall is the next most important thing to cover. If you are recording anything inside the room like any music or song, then you must have to soundproof the walls, or else it will create an echo.

There are so many ways to soundproof the walls of the room and these ae the following ways which I prefer most:

  • Use Acoustic Foams: There are many great acoustic foams available in the market and they work really well because they have high density and thick also. When you place them on the walls, they absorb the sounds and don’t let them bounce back. Covering the whole wall with acoustic foams will be costlier so it is better to cover only small portions of the walls.
  • Use Old Mattresses: If you want to cover the whole wall and don’t want to invest much money, then you can get some old mattresses from somewhere and place them beside the walls. It will cover more area than soundproof foams and it is more effective also. Yes, it won’t look good compared to acoustic foams, but if you just want to record some music or video, you can use this.
  • Use Soundproof Paints: This is the last thing which I will prefer because it is not as effective as acoustic panels but if you want to soundproof the walls, applying acoustic paint is a nice option.

Soundproof Windows

After you soundproofing the walls, the very next thing is to soundproof the windows. If you don’t want your inside noise to reach outside, then soundproofing the windows is important.

There are many ways but the following ways are the most effective ways to soundproof the windows.

  • Soundproof Curtains: When it comes to soundproofing the windows, obviously the cheapest way to do this is hanging the soundproof curtains on the window. Not all the company who claims their curtains as acoustic curtains are not really. So, always check manually whether the curtain is acoustic or not. I prefer the NICE TOWN soundproof curtains always.
  • Use Green Glue: If there space between the window frame and wall then you need to fill those holes with the help of some soundproofing compound like green glues.
  • Use Double Glazed Windows: I know installing a double glazed window is very costly and it is not a DIY technique. But if you want to make the room perfectly soundproof then it will help you a lot.

Use Blankets

After you soundproof the floor, window, wall, rest is the door and ceiling. There you can use a good thick blanket.

The blankets are very good sound absorber because they are thick and doesn’t let sound bounce back into the air.

If you are making the room soundproof from inside because you want to record something or it is a studio, then only go for the blankets actually, or else it really looks bad.

If you want to soundproof the doors, then you can easily pin the blankets on the door(only if the room belongs to you and you are not living on rent). And if you don’t have the permission to pin the blankers on the door then you can try pasting it using double-sided tape but I must say that doesn’t last much.

Soundproof Ceilings

Actually soundproofing ceilings are not that important but if you want perfection then you can go for it. Ceiling soundproofing is actually costlier and isn’t that important.

FAQs On Soundproofing Rooms

The best product to soundproof any music room is acoustic foams(if you want to invest money), and used or old mattresses(if you want to invest reasonable money).

If you have done soundproofing with good materials for example you used glass doors, glass windows, good acoustic foams, etc then a room can stay soundproof for several decades(even for lifetimes).


The most important thing to soundproof a room from inside noise is to place some items of furniture inside the room like chairs, tables, books shelves, etc.
