While we treat our basements to be nothing but storage space, these spaces can be utilized to be a lot of things. If you want, you can easily convert your basement to a gaming room, an entertainment room, a music room, a home gym, a craft room, a theater room, an indoor games room, and many more. To do these things, you need to learn how to DIY a soundproof basement. 

However, when you’re doing these, you need to make sure that the sound from the basement isn’t disturbing the people living above you, and around you. Even if your basement will be under the ground mostly, still, the sound can travel through the air and light vents, and they can reach your neighbors easily. 

Plus, no matter what you do, the sound will reach easily to the people living in your home through the structures of your house, especially the beams and the ceiling of the basement. 

This is why it’s very important to have a soundproof basement. In this article, we’ll take a look at the steps through which you can get a completely soundproof basement, so that no sound goes out, and none comes in. 

What Your Goals Should Be to DIY a Soundproof Basement:

When you’re soundproofing your basement, there are two types of sound mediums that you need to deal with. For starters, you need to deal with airborne sound, and then you need to deal with structural sounds. Let’s talk about them in detail. 

Structural Sounds:

The basement is right above the foundation of your building, and usually, the basement is a single section with no walls in between. In such cases, there will a lot of beams in the basement, and the sound created in the basement will likely reach the other floors through the beams. 

Then again, if someone makes a sound above you, there’s a high chance that you’ll be pestered by that sound. So, it’s important to dampen these structural noises for everyone’s peace of mind. 

Airborne Sounds:

Sound mainly travels through air, and you’ll need to take some steps to dampen the airborne sound that’ll be generated from your basement. Sound travels through vibration, and unless the vibrations hit a solid object that can absorb the sound, then the sounds will keep on traveling forward. 

This is why it’s important to ensure that your basement is draped with sound-absorbing materials so that the sound originating from your basement doesn’t reach outside. 

Materials That You’ll Need for a Soundproof Basement:

These are the materials that you’ll need for soundproofing your basement:

  • Caulking seals
  • Padding
  • Acoustic panels
  • Mineral insulation
  • Resilient channels
  • Glue
  • Soundproof paint

How to DIY a Soundproof Basement?

In this section, we’ll talk about the steps that you’ll need to take for soundproofing your basement. Let’s get to it. 

Pad the Walls:

One of the main things that you need to do while soundproofing your basement is padding the walls of your basement. There are many different soundproofing materials that you can use. However, there are only a few that are considered the very best. 

In most cases, you won’t need to pad the walls of your basement, unless there are multiple sections of your basement. For example, if your basement has two rooms where one is used as a study room and the other is used as a theater room, then there’s a necessity of padding the walls. 

On the other hand, if the entire basement is used as one room, then there’s no necessity of padding the walls. However, you still need to pad the ceilings. The ceilings are directly connected to the floors above you, and you need to dampen the sound that might travel through the ceiling. 

Otherwise, the sound of people walking above you will surely irritate you from time to time. Then again, the sound originating from the speakers in the basement will reach the people living above easily. 

In essence, the ceilings are the main place that links the basement to the outer world. This is why you need to dampen the sounds that might pass from the ceilings. 

You can use drywall to do this. Drywall is very affordable, and they’re quite easily found as well. However, if you’re looking for something aesthetic and visually pleasing, then you can go for acoustic foams. Acoustic foam is quite affordable nowadays, and you can find them easily as well. 

Mass-loaded Vinyl:

If you’re looking for something more subtle than acoustic foam tiles and drywall, then you can use mass-loaded vinyl. Mass-loaded vinyl is a type of dense material that’s full of small metal particles. Due to its construction, mass-loaded Vinyl or MLV can absorb sound very easily. 

If you use mass-loaded vinyl, you’ll be able to dampen both airborne and structural sounds. Then again, you can cut this material and give it any shape you want as it’s available in the form of sheets. 

Once you’re done cutting the MLV sheets appropriately, you can hang them on the walls with nails and pins. This makes the MLVs truly DIY. 

Seal the Gaps:

No matter how many materials you’ve used to soundproof a room, there will always be some gaps. For example, if you use MLVs to soundproof your basement, even then there will be some gaps in them. 

Other than using the MLVs in an overlapping pattern, you can use some special material to seal the gaps between them. Then again, there might be other gaps that are impossible to cover with MLVs or drywall. You can seal these with acoustic caulking or weather-stripping. 

Both of these are very effective when it comes to soundproofing. These are usually made of a material that is vibration and shock absorbent, so it’s easy for them to absorb any sound. 

Work on the Door:

If the door that connects your basement and the ground floor is hollow, then it needs to be changed. We highly recommend getting a solid door that’ll be capable of blocking all sorts of sounds. 

Then again, if you’re low on budget, you can hang some sort of sound-absorbing blanket over the door, as this will work to give you a soundproof basement too.
