If you have a basement at home, then this article is for you!
Regardless of what you’ll use the basement for, we highly recommend that you soundproof its ceiling. Soundproofing the ceiling helps reduce the impact noise coming from other levels of your house and down to the basement floor.
Not only that, but soundproof ceilings also help reduce noise coming from inside your basement and out.
In this article, we’re here to help you find ways to soundproof a basement ceiling and get rid of unwanted noise.
What are you waiting for? Let’s get to it!
The Basics of Having a Soundproof Basement Ceiling
Whether you’re an aspiring musician wanting to create your music studio at home, or someone who wants to have their very own entertainment system, keep on reading, and we’ll teach you how to soundproof the ceiling in your basement and prevent impact noise from going in and out!
Soundproofing your basement ceiling is easier than planning to soundproof your entire house.
Unlike other parts of your house, the only thing you’ll have to soundproof on your basement is the ceiling and perhaps a window or two that needs to be covered.
You can choose between spending a fortune or doing a simple DIY project or two to fix the noise in your basement.
The primary thing you need to know when it comes to soundproofing is that you have to interrupt where sound passes.
Remember, having a tight space is better because it prevents sound waves from getting through and escaping to another floor.
Doing this helps insulate noise in one particular area, and interrupts sounds from traveling to one floor to another.
Luckily, you can easily soundproof a basement ceiling. All you need to remember is to add more mass on the basement ceiling so that it can absorb sound waves traveling across the floor.
Before starting with the different ways to soundproof a ceiling, it’s vital that you know and understand the various elements of soundproofing.
1. Absorption and Density
A crucial factor we need to talk about when we speak of absorption is the density of the material.
For example, fluffy pillows appear to be able to absorb airborne noise. However, when comparing this to a dense material, such as fluffy fiberglass, you’ll find that the pillow doesn’t perform well because it’s not as thick as fiberglass.
Moreover, adding a single layer of drywall won’t necessarily be effective at reducing noise. You might need to add more layers to make sure that you can reduce noise transfer.
Remember, you need to select denser material for soundproofing ceilings or any part of your room. The denser it is, the better it is at absorbing sound and eliminating impact noise and airborne noise.
Although the solution sounds relatively simple, you’ll find that you might need more materials for adding mass.
We recommend using the following materials, known for being dense and having excellent absorption properties, for soundproofing a ceiling at home:
You can also use some of these products we recommend for adding mass on your basement walls:
- Drywall: Regular drywall can get the job done in no time. You’ll only need to place it on the underside of your subfloor, and you’ll start noticing a significant reduction in the sound transfer. We highly recommend pairing your drywall with green glue, to make sure that you block sound effectively.
- Soundproof Drywall: Between regular drywall and soundproof drywall, the latter option prevails. Although it has the same outcome as using regular drywall, you won’t need to add multiple layers when already using soundproof drywall.
- Fiberglass: There are different types of fiberglass to choose from, all of which are effective at soundproofing. We recommend using acoustic and rigid fiberglass insulation panels because they are easier to find and more effective than regular fiberglass.
- Acoustic Foam Tiles: Foam tiles function like any drywall in the market. It can reduce sound transmission effectively.
- Mineral Wool: Unlike fiberglass, mineral wool is denser, and stays in the joists better. You can use it in between joists, and you’ll already notice a significant improvement in noise reduction.
2. Damping and Decoupling
Damping your basement ceiling is one of the easiest ways of preventing and reducing sound waves from traveling.
Decoupling, on the other hand, involves creating separate levels between the layers of your ceiling. The gap helps break the passage of sound waves and vibration.
You can use materials like:
- Green Glue: It dampens noise, reducing sound waves and mechanical vibrations. Green glue sealants or the use of acoustic caulk is useful and effective in sealing small gaps even on your windows and doors.
- Sound Isolation Clips: One of the best ways to decouple your basement ceiling is by attaching sound isolation clips. Attach it to the joint of your stairs to prevent sound waves and vibration from traveling across the floor.
- Viscoelastic Damping Materials: You can also apply green glue between the joists of your ceiling and floor to prevent the transfer of sound vibrations.
Step-by-Step Guide to Soundproof the Ceiling of Your Basement
Basements are handy rooms to have at home. They can double as an extension of any part of your house or be used as new living areas, living spaces and entertainment rooms. It can extend your home in no time!
If you aren’t using your basement just yet, it’s time to repurpose them now. You can transform it into your office area, workshop, playroom, home theater, and more! The possibilities are endless!
There are different ways to soundproof a basement ceiling. But before we get started with that, make sure to inspect your ceiling for any gaps and cracks.
As much as possible, you want to seal any parts of your ceiling where sound can penetrate. One of the common areas where cracks usually develop is under door frames and stairs, depending on the layout of your basement.
You can DIY the whole sealing process because the materials you’ll need are easy to find. All you’ll need is a soundproofing sealant to prevent sound from leaking out of the room.
Today, we’ll give you a detailed guide on how to seal soundproof a basement ceiling based on the following circumstances:
- Creating a new basement
- Unfinished ceilings
- Finished ceilings
1. Creating a New Basement
It’s easier to work on soundproofing your basement ceiling if you don’t have to remove any existing space yet. You can start from scratch and address the common concerns of soundproofing ceilings’ such as insulation, airspace, and materials.
Step 1: Install the Drywall Under Your Floor
Start by measuring the spaces between your ceilings joists and its entire floor size. Usually, the spaces between the joists measure the same.
Using the dimensions you’ve taken down, start cutting your drywall. Once done, begin dry fitting it by applying an even layer of damping compound on the side that goes against subfloors. Do the same for the rest of the drywall you’ve cut down.
Next, hammer the drywall on the subfloor and screw it in place.
Step 2: Place Green Glue
Before installing the second layer of drywall, we recommend applying an acoustic compound like green glue in between the first and second layers of your drywall.
Using green glue can help double the thickness of your ceiling, and it’s an easy and cheap solution!
Not only that, but you can also use green glue to seal the corners and edges of your drywall. Green glue can dampen the sound between the two layers, making it more effective.
Step 3: Install a Second Layer of Drywall
Now that you’re done installing the first layer of drywall, it’s time to create the second layer. Again, using the same measurements, cut your drywall.
On one side, apply an even layer of green glue and secure it beside the first layer and screw them in place.
Having two layers of drywall increases the density of your ceiling, making it hard for sound to travel.
Step 4: Install Your Insulating Material
It’s time to cut your insulating materials, based on the same measurements of your drywall. You can use fiberglass or mineral wool insulating materials for this process.
Using the pieces you’ve cut down, insulate the joist cavities on your ceiling. Push the material in place, and be sure not to leave gaps on the edges.
You can also use soundproof mats on your ceiling because it works just as well at blocking sound from passing through. It’s flexible and has great density!
Step 5: Install Isolation Clips
Installing resilient sound isolation clips is easy because all you’ll have to do is attach it to the joist. It can block any noise vibration and reduce impact noise across the floor.
Make sure to attach the clips evenly and correctly align them. Doing so makes sure you won’t have a hard time installing your resilient channels later.
Step 5: Install the Resilient Channels
Once you combine your isolation clips with resilient channels, they can significantly reduce any impact noise and vibrations.
Installing resilient channels on your ceiling create gaps between your drywall and the structure of your ceiling.
Make sure that you don’t install the resilient channels too close to your ceiling. You want to prevent them from touching each other so that sound won’t quickly transfer from one floor to another.
Optional Step 6: Install Another Layer of Drywall
If you want to effectively have a soundproof ceiling, you can create another layer and repeat Steps 1 to 5.
Step 7: Seal Everything With a Soundproof Compound
The final step of this process is by sealing any gaps with a soundproof compound. This step is especially crucial so that your hard work won’t be for anything.
2. Working on Unfinished Ceilings
If your basement is halfway done, you can still save it and soundproof your basement ceiling. Doing so is simple, and you’ll only have to add in the insulation.
Before closing down your basement ceiling, add insulation on the joists. It can absorb sound and isolate any impact noise coming from the floor above your basement.
You can also use acoustic tape on the joists where you plan to attach the furring strips to help reduce and prevent any sound waves and vibrations from any sound transmission.
The only problem you’ll experience with working on unfinished ceilings is that they’re very time-consuming. You’ll have to work on an already existing roof and make sure not to damage it.
Another drawback to using this method is that it doesn’t help improve the sound quality on your main floor.
3. Soundproofing a Finished Ceiling
It’s harder to work on a basement that’s already structurally finished. You’ll have to take down any existing structure, make a mess, and spend a little more to fix it again.
But if you don’t want to do this, here are some tips to help soundproof your ceiling without tearing it open or breaking it down.
Repair Your Drywall
Inspect the drywall of your ceiling and check for any cracks and gaps. Having them present provides a passage for noise to travel in your basement. You can easily seal them with any soundproof seal and you’re done! You can even go the extra mile of painting over it to hide the repair.
Replace Your Existing Drywall
If the cracks and gaps are too many to repair, we suggest replacing them with brand new ones. That way, you’re sure that it’s completely soundproof and new!
Add Another Layer of Drywall
You can opt to add drywall on your ceiling to add more mass. It prevents sound from transferring to the basement. Moreover, adding another layer is cheaper than having to take down your existing ceiling.
Install Soundproof Mats on Your Ceiling
You can easily install soundproof mats on the joints of your ceiling, over or under your drywall. However, mats only come in one color, black. So if you’re worried and picky about your basement looks, then the color might be a concern for you.
Easy DIY Alternatives for Soundproofing Your Basement
There are different ways to soundproof a basement ceiling without necessarily doing any major works. There are various cheap materials you can use to soundproof a basement ceiling. Here are some of our top suggestions:
1. Use Soundproof Acoustic Panels
Acoustic panels are known to be highly durable, great at insulating the sound. This acoustic insulation solution is so dense, measuring a density of 200 kg/sqm.
Acoustic insulation provides more mass to your basement ceiling, making sure to absorb any noise or sound present in the basement.
Acoustic panels are one of the great ways to soundproof your basement!
You can place it in any area where you want noise or vibration to be absorbed. You’ll see a significant improvement in terms of your ceilings’ sound quality and echo in no time.
You can easily attach the panels to any part of your ceiling, whether you use it on the ceiling, floor, or wall! All you’ll have to do is secure it by using an acoustic tape or blue tack.
Using this type of acoustic insulation can also reduce the feedback of your speakers or home entertainment, reducing the vibrations and echos, giving a fuller and better sound quality.
However, the only problem we have with using acoustic panels is that they’re not great at preventing sounds from leaking inwards, and they’re quite expensive to buy.
2. Use Mass Loaded Vinyl
Mass loaded vinyl (MLV) are perfect to use on any wall or ceiling because it’s a flexible and all-around material for minimizing noise transfer. You can even improve the effectiveness of this product by combings its use with a sound-absorbing product.
Placing the vinyl material on top of your drop ceiling tiles adds more density to it, decreasing any impact noise traveling across different floors.
Adding the MLV to the back of your acoustic panels also helps in improving the sound quality in your basement and reduce vibrations.
3. Place Acoustic Sound Foams
Acoustic sound foams are extremely easy to use because they can be stuck on your walls and ceilings.
You can apply acoustic foam on your entire basement ceiling, or create alternating patterns to improve sound reduction and quality.
4. Lay Down Carpets, Mats, or Rugs
Rugs, carpets, and acoustic mats are great at absorbing sound, and they’re available anywhere. It can prevent any outside noise from coming inside your basements, such as the sound of footsteps, regular chatter, radio, and more.
But the best part of using rugs is that they’re very cheap so that you can lay them down on the noisiest parts of your house without any problem.
We suggest choosing thick, soft, and dense rugs because they can absorb noise better than most. They’re comfortable to walk on, thanks to its texture, and it can get rid of any unwanted noise coming in and out of your basement.
Acoustic mats are specially designed to provide a means of isolating noise in most visited areas of your home.
If you lay them on the floor above your basement, it can significantly reduce any noise and vibration transmitted below.
You can also put the rugs in your basement to add mass and absorb any echoes within, improving the room’s sound quality.
You can also combine using rugs with a rubber floor mat because they’re also known for being thick and dense. They can absorb noise better without spending a fortune!
However, if there’s one drawback to using mats, rugs, and carpets, it isn’t as effective as other solutions out there. Noise can still leak outwards, disrupting the people above your floor!
5. Soundproof Your Door
No matter how hard you work on soundproofing your basement, sound can still leak from inside out or vice versa. This problem is especially real if there are gaps on your door or if the door is made of thin material.
If there are gaps on your door, you can quickly solve this by putting foam tape around the gap. It can reduce any vibrations, preventing sound from going in and out of your basement.
If the problem is with the density of your door, we suggest applying medium density fiberboard. If not, you can replace it with any doors that have better density.

6. Improve Your Air Conditioning and Plumbing
Often, the problem could be because of the air conditioning or ventilation inside your basement. Usually sound can escape from the gaps around the vents, which allows sound to unnecessarily travel inside.
Moreover, you should also check out the plumbing in your basement. Often pipes make weird sounds even when you’re not using them!
7. Rearrange Your Furniture
If you don’t want to spend a dime, rearranging the furniture on top of your basement floor is a great ceiling soundproofing idea.
It can improve the acoustic inside your home and reduce sound from leaking into your basement in no time! All you’ll need to do is find the best spot and position to minimize noise.
We suggest placing all your heavy furniture like shelves and couches above the basement. You can also try moving around your furniture to check which position is better!
However, the only drawback to this solution is that it’s challenging and labor-intensive. You’ll also risk damaging your floor if you’re not careful.
