How to Properly:- We hosted a cocktail party several years in the past. Nothing fancy, only a handful of mates and us. As we had been having a beautiful chat (and meals, in fact) within the eating room, the children went to play upstairs.
And then, it began.
We might hear each phrase, each giggle, and combat over who needs to be taking part in this or that toy. The sound of each dropped Lego brick or one other toy resonated downstairs. Their working round seemed like a drum competition to us.
The youngsters weren’t doing something incorrectly. But due to the best way the home was constructed, the sound carried downstairs to the place we had been. It was a cacophony and at some unspecified time in the future, we might hardly hear one another.
I do know I needed to do one thing. Dinner events like this might not occur once more.
So I did. I soundproof the ground and managed to considerably scale back the noise bleeding downstairs.
Let me share with you what I’ve realized. And let’s begin by getting one thing out of the best way.
Can you soundproof the flooring?
Short reply, sure, completely.
(And earlier than you ask, no, there is no such thing as a “but” coming.)
You can soundproof flooring, and scale back the various kinds of noises that usually bleed employing – foot noise, transferring issues around, and even conversations. Full cease.
Before you dive into this soundproofing challenge excitedly, although, we have to talk about how the noise will get to the rooms under. The cause for that’s easy: as soon as you understand how the noise will get in, you’ll be capable of knowing how you can cease it in its tracks.

We hosted a cocktail party a number of years in the past. Nothing fancy, only a handful of mates and us. As we had been having a beautiful chat (and meals, in fact) within the eating room, the children went to play upstairs.
And then, it began.
We might hear their each phrase, each giggle, and combating over who needs to be taking part in with this or that toy. The sound of each dropped Lego brick or one other toy resonated downstairs. Their working round seemed like a drum competition to us.
The youngsters weren’t doing something incorrect, in fact. But due to the best way the home was constructed, the sound carried downstairs to the place we had been. It was a cacophony and in some unspecified time in the future, we might hardly hear one another.

So I did. I soundproof the ground and managed to considerably scale back the noise bleeding downstairs.
Let me share with you what I’ve realized. And let’s begin by getting one thing out of the best way.
Can you really soundproof a flooring?
Short reply, sure, completely.
(And earlier than you ask, no, there is no such thing as a “but” coming.)
You can soundproof a flooring, and scale back the various kinds of noises that usually bleed by means of – foot noise, transferring issues round, and even conversations. Full cease.
Before you dive into this soundproofing challenge excitedly, although, we have to talk about how the noise will get to the rooms under. The cause for that’s easy: as soon as you understand how the noise will get in, you’ll be capable of know how you can cease it in its tracks.
Your largest problem with flooring soundproofing
In most circumstances, airborne sounds – conversations, music or TV, and many others. – don’t journey to the room under the ground.
They do when shifting the other manner, although. Often individuals upstairs can hear your conversations under and a few of that sound reaches them via the ground.
However, relating to listening to noises downstairs, many of the airborne noises will get downstairs via different pathways. Airborne sound can attain you from upstairs via open doorways, and many others. You might imagine they hear a dialog via the ground however in case you hearken to it fastidiously, you’ll discover that the sound bounces off partitions and different constructions, and enters the room via the door or home windows.
The scenario is sort of totally different with foot noise and different impression noises, although.
The sound of shifting furnishings upstairs, the clank of dropping one thing on the ground, or the noise of dropping one thing heavy on the ground all bleed from the room upstairs as a result of the ground construction turns these sounds into vibrations and passes the vitality to the room beneath.
It works like this:
Notice how the purpose is the place the dropped ball hits the ground. See how its vibrations stem in all instructions and journeys via the construction of the ground. Now, a few of these sounds will mirror the room and the place the noise is coming from. But observe one thing attention-grabbing on this graph:
Most of the vibrations journey elsewhere!
And most of it results in the atmosphere under the supply of noise.
What does that inform us about soundproofing flooring?
For one, the physics of sound transmission via the ground tells us that noise and air pollution could be lowered. And additionally, to do it, we have to block these vibrations from reaching us.
Luckily, there’s a course for that.
How to soundproof a flooring – a 3-step course of
A fast observation earlier than we dive into the method.
What I’m describing in this part aren’t the precise steps to soundproof flooring. Usually, you must do way over simply three issues to dam or take up these noises from above.
What this part covers are the levels of the method. I like to consider these as aims you could obtain with completely different ground soundproofing strategies to dam the sound from coming by present flooring.
So, with none additional ado, here’s what you could do to soundproof a ground correctly.
Objective 1. Separation
Take a glance once more on the visible exhibiting how sound travels by the ground. Notice that it’s the tight connection between the upstairs and downstairs that enables sound vibration to journey by.
So, the primary goal of a ground soundproofing undertaking is to sever that connection. There are a number of methods to do that. You can both increase the ground floor upstairs and create one thing like a floated ground. The different possibility is to decrease the ceiling under. The goal is to have at the least one floor disconnected from the construction of the constructing.
NOTE – In this case, separation doesn’t imply detachment. As you’ll see shortly, including underlays or mass-loaded vinyl under the carpet or floorboards will provide help to obtain that separation, though, technically, all surfaces will lie on high of one another.
But in fact, you too can do it by including one other layer to the ground (or ceiling, for that matter) and create an precise separation. This is commonly the best methodology to soundproof something. But it’s additionally the costliest and ridiculously time-consuming.
Why is attaining this separation so necessary? Well, that separation will trigger the noise vibration to die quite than proceed by. Again, seek advice from the visible above. See that the sound travels solely on joists and beams, not the air. That is the character of impression sounds, and one of the simplest ways to cease them is to take away a way for the vibration to journey.

Objective 2. Reducing the vibration with ground therapy
Next, you could scale back the extent of vibration on the supply.
I do know; it sounds very technical nevertheless it’s really fairly a easy idea. By putting components that may both take in the sound or cease it in its tracks, you scale back the quantity of vibration getting into the constructing’s construction.
I’ll present you many strategies to do that shortly. But generally, finishing this step entails laying out some soundproofing underlayment. In some circumstances, the underlayment also can work as a solution to increase the flooring floor (however once more, that is dependent upon the soundproofing supplies and methodology you’ll use – extra on this shortly.)
Objective 3. Blocking means for the airborne sound to cross by
Now, I do know that I referred to as impression noise your greatest problem. But that doesn’t imply that some airborne sounds can’t get by. Cracks, even tiny ones on the ground or across the partitions can transmit sound vibration to the atmosphere under.
Luckily, as you’ll see shortly, stopping that isn’t really that troublesome, and plenty of soundproofing supplies may help you block sounds from passing by.
So how do you do all of it?
What to do to soundproof a ground: 11 strategies
Disclaimer: Most of the recommendation I’m going to provide you under pertains to attaining the 2nd goal I described above. Naturally, elevating a ground or decreasing the ceiling requires a special strategy, and more than likely, it’s a much bigger undertaking. You would possibly must seek the advice of your builder about attaining that goal.
That mentioned – Some of the ground soundproofing strategies may also make it easier to obtain that separation. It may not be as efficient as in case you’d increase the ground however it is perhaps sufficient.
So, in no specific order, listed below are the perfect strategies to soundproof a ground
1. Lay out interlocking ground mats
I admit it; these puzzle-style, interlocking ground mats don’t look spectacular. They aren’t one thing you’d use in a bedroom. But in case you’re soundproofing the ground in a child’s room, an upstairs gymnasium, or the same room you employ casually, they’re good.
You see – interlocking mats soak up the impression that appears loopy!
Interlocking mats are normally fabricated from rubber materials. You’ve most likely seen that though they’re sturdy surfaces to stroll on, additionally they feel a lot softer than hardwood flooring, for instance.
That’s additionally one cause why you see them specified by gyms and sports activities halls. These mats can defend you and decrease the impression whenever you fall.
And for a similar cause, they will additionally make it easier to soundproof a ground. Their rubber construction will soak up and cut back the quantity of vibration generated by impression – footsteps, working, thumping, and so on.
That, coupled with a mix of tile colors which you can get them in, and even completely different designs, makes interlocking ground mats good for soundproofing children’s rooms, gyms, and some other rooms the place you may not be bothered by their design, however, must considerably cut back the impression noise on the ground.
2. Use thick rugs or carpets to scale back sound vibrations
This is by far the simplest method to soundproof flooring. Thick and delicate carpets can soften the sound of your footsteps and scale back the number of vibrations that are reaching the ground.
In this case, these carpets will even create a separation between the sound supply (your toes!) and the ground. Now, they gained’t get rid of the vibration utterly. However, by softening the impression of your footsteps, they may scale back the quantity of vibration that can hit the ground and transmit additional by its construction.
Carpets have been additionally one of many strategies I used to scale back the noise from children taking part upstairs. You see, at the time of that feast, we simply had panel flooring laid out. This signifies that 100% of the impression noise vibration was coming into the ground construction.
I laid out carpets in some rooms and used colorful rubber interlocking flooring mats (like these) in my children’s room. The distinction was noticeable. Far much less impression noise was bleeding downstairs.
TIP: If you don’t have the carpet within the room upstairs already, and will probably be contemplating getting one, go for one thing tightly-woven. Such carpet will take in much more vibration and forestall it from resonating on the ground construction.
3. Put a rug underlay underneath the carpet
You know that carpets can soften impression sounds, and scale back the quantity of vibration resonating by the ground floor. We’ve mentioned how, in lots of instances, a thick, tightly-woven carpet would possibly even be sufficient to scale back the noise from the rooms upstairs.
But you’ll be able to strengthen that impact by inserting a rug underlay underneath the carpet.
By spending just a bit additional, you may get a soundproofing carpet underlay that can considerably enhance the carpet’s potential to soak up and deaden footsteps and different impression noises. The underlay, as the identity suggests, goes underneath your carpet, and creates one other barrier for the impression sound vibrations to undergo.
You have several choices when selecting the underlay. You can use PU (Polyurethane) foam, crumb, sponge rubber, and even an underlay fabricated from a mixture of all these supplies.
However, it’s the PU foam that provides the largest advantages for soundproofing flooring. It is comprised of recycled foam off-cuts. It seems like this.

You can get it in a roll to roll out underneath the carpet or in sheets. Many recording studios use these underlays to deaden sound and add a layer of soundproofing to the flooring but in addition partitions and ceilings!
4. Use rubber mats as a substitute for carpet underlay
One drawback of a carpet underlay is that it may be fairly thick. In truth, the thicker the underlay, the stronger its soundproofing capabilities.
But after all, it may be too thick to have within the room. Luckily, there may be another choice – a rubber mat that you should use as a substitute for a carpet underlay.
Putting a rubber mat underneath the carpet will generate the same consequence to the underlay. It will take in a number of the sounds of footsteps and different influence noises, additionally by including mass to the ground (in the same approach because the mass-loaded vinyl would – extra on this flooring soundproofing materials in only a second.)
But the rubber mat itself is far thinner and might be much less noticeable.
Another advantage of utilizing a rubber mat is that it additionally makes the carpet slip much less or in no way. Most rubber mats are non-slip and subsequently will forestall the carpet from transferring and sliding on the ground.
TIP: If you wish to create a brilliant thick separation from the ground, use a rubber mat and an underlay underneath the carpet.
5. Add soundproof underlayment below laminate or one other flooring
This is an choice for you if you happen to don’t need to roll out a carpet upstairs and like the look of laminate or hardwood flooring. The premise of this technique is much like what we simply mentioned above when speaking about rubber mats and carpet underlays – to create a seal that can block affect sound vibrations from reaching the construction of the ground.
In this case, nevertheless, you place that seal below the flooring.
Products like FloorMuffler go straight onto floorboards. Their job is to soak up any vibrations and cease them from resonating additional into the ground construction. What’s extra, these merchandise usually additionally act as a vapor barrier, stopping moisture from penetrating via your flooring.
There’s one factor to bear in mind right here – Laminate or hardwood flooring will generate a considerable quantity of vibrations. There is nothing that will soften the affect, in spite of everything. Your ft will hit the ground straight.
6. Use cork tiles above or under the floorboards
Now, it is a extra invasive technique however one that may ship unimaginable outcomes.
Cork is a pure sound dampener. The materials has glorious sound absorption properties that may stop sound vibration from touring via its floor, and cut back the quantity of noise that may attain you downstairs.
Cork additionally has sound discount properties, which means that, very similar to carpet underlays, it may cut back the quantity of vibration getting into the ground construction.
In truth, some sources say that utilizing a cork floating flooring and cork underlay, coupled with the ground’s pure construction can cut back the noise to as much as 99db. And that’s the extent of noise generated by manufacturing facility equipment.
Cork often is available in sq. tiles that you simply lay down on the floorboards. However, you may also get hexagonal tiles that might look good with out every other layer of flooring on high of them.
One phrase of warning if you wish to use cork tiles uncovered. These tiles aren’t absolutely waterproof. So, it’s all the time a good suggestion to make use of them as an underlayer, reasonably than a ultimate layer of flooring.
7. Add mass-loaded vinyl below the carpet or the ground
Mass-loaded vinyl (MLV) is a brilliant heavy materials product of vinyl impregnated with steel particles to extend its mass. It’s one of the crucial common and efficient soundproofing supplies, and you should utilize it to soundproof flooring in addition to blocking the sound coming through the wall.
You can use MLV as a carpet underlay. No one will see it despite everything, and the added mass of MLV will present much more vibrations from stepping into the ground construction.
But you too can use it as a flooring underlayment and put it below your flooring. In both cases, it is going to work in the very same approach, stopping a lot of the affect vibrations from getting any additional.
8. Insulate the area between flooring joists
Joists are the ground equal to the studs you discover in your partitions. These joists assist the upstairs flooring in addition to the ceiling beneath.
But typically, that’s it. There is nothing else around these joists.
Now, a lot of the sound vibration will journey on the joists. The very first goal in soundproofing flooring, if you happen to keep it in mind, aimed to disconnect these joists from both the ground above or the ceiling so that the vibration would collapse.
But you could additionally insulate that hole area between the ground and the ceiling. Otherwise, it is going to solely amplify the noise, very much like an acoustic guitar’s physique.
9. Add joists isolators
If you’re including the acoustic insulation foam between the joists, then I like to recommend you add isolators on the prime of them. These strips of rubber glue onto joists and separate them from the subfloor above. Their job is straightforward – to eradicate the vibration of the subfloor from reaching a joist. Because if the vibration by no means will get there, there’s nothing for the joist to transmit additional down the construction.

10. Use Green Glue and Plywood approach
Green Glue is, most likely, probably the most well-known soundproofing material on the market. There is an efficient purpose for that too. Not solely is Green Glue versatile, but it’s additionally efficient.
You can use Green Glue to fill in any cracks and forestall airborne sounds from getting in. But you too can add it between two exhausting surfaces, like your floorboards and cork tiles, for instance, to additional strengthen the construction’s soundproofing capabilities.
Or you may connect a layer of plywood, which is good to put down on the ground and supply sound-dampening capabilities to your ground.
How does Green Glue assist soundproof a ground?
Most of the time once we discuss Green Glue, we give attention to utilizing it to soundproof a wall. But in this case, the vibration of the plywood if you stroll on it (word – your plywood might be coated with a carpet or some other flooring materials) will warm up the Green Glue. This, in flip, will convert that sound vibration into thermal vitality, deadening it within the course of the.
Green Glue is tremendously simple to deal with and apply. You simply want a caulking gun and sufficient of the Green Glue to cowl the floor, and also you’re good to go.
Just keep in mind that you’ll want a considerable quantity of the compound to cowl the ground, so be sure you order it accordingly.
11. Add a brand new layer of flooring
There are several eventualities by which you would possibly wish to add a brand new layer of flooring to the prevailing ground.
First of all, that’s among the finest methods to attain the separation we’ve talked about above.
Also, including a brand new layer of flooring would possibly assist you to improve the general thickness (or the mass) of the ground, and enhance its soundproofing qualities. The logic behind that is that the thicker the floor sound vibration must cross, the much less of these vibrations will get by way of.
But there are drawbacks to this technique too. For instance, should your ground is a hole, with solely joists there, then including a brand new layer of flooring gained’t change a lot. Your empty ground will nonetheless resonate, very much like the acoustic guitar we coated earlier.
In that case, it’s best to first fill the hole space with acoustic insulation, and solely then proceed to add a layer of flooring.
When it involves your choices, you may lay out a brand new layer of laminate or tiles. You also can add a layer of corkboard because it has a pure sound-dampening high quality.
Also, be certain to analyze knowledgeable suggestions for including a brand new layer of laminate or one other flooring. For instance, one factor most specialists at all times advocate is tearing the prevailing ground right down to the subfloor, and including new layers from there. The purpose is that by opening the ground proper to the subfloor, you get an opportunity to handle some other soundproofing points. One of them is filling the ground with acoustic insulations. You also can add the joist isolators we talked about earlier, repair some shifting joists to scale back squeaks, and so forth.
One very last thing – Here’s what to do should you dwell in a rented house and must soundproof a ground
So far, I’ve been displaying you soundproof ground in a home, since that’s the place I had the noise challenge. But I do know that lots of my readers dwell in flats, and so they usually lease their lodging.
I admit it; this makes it tougher to implement a few of the ground soundproofing concepts I’ve shared.
Not unattainable, although.
In truth, not less than several of the strategies to soundproof a ground I listed will work in a rented house too.
Just give it some thought – You most likely can elevate the carpet and set up an underlay or a rubber carpet mat.
You also can roll out thick carpets. I don’t suppose the owner would have something in opposition to that, for the reason that the carpet won’t require amending the construction of the ground in any approach.
I feel you must also be capable of laying down mass-loaded vinyl. Although, because it must be glued to the ground, ideally with Green Glue compound, in this case, you would possibly get permission from whoever owns the house.
Best of luck with your ground soundproofing challenge!
