Does sound travel through concrete floor?
Most buildings with a concrete sub-floor have sufficient mass and density to block the transfer of airborne sound. Conversation and TV noise would not normally pass between the floors of buildings that use concrete as the sub-floor. The main noise issue that you would expect for concrete flooring is impact sound.Jul 15, 2021
Do concrete floors stop sound?
But one thing concrete can't quite claim to provide is great soundproofing quality. Even though concrete is excellent for providing durability and lasting quality, it fails to provide the level of noise reduction most homeowners desire.Aug 10, 2021
Can you hear neighbors with concrete floors?
Yes there's noise through walls from adjacent neighbors, but be aware of impact noises above. If floors are hard (not carpet) expect to hear footfall noise unless a resilient underlayment was properly installed in the units and/or the ceiling is isolated in the unit below.
Are concrete floors good for acoustics?
For acoustic reasons, a concrete floor can be seen as one of the best flooring options for a recording studio. However, the choice of concrete requires specific minimum space and ceiling dimensions to receive the optimal acoustic benefit.Sep 23, 2021
Are concrete buildings quieter?
Yes, concrete buildings are, in most cases, quieter than wood frame buildings. There is only one type of frequency that has a higher tendency to transmit to the floor below; the small sharp heel of a shoe. Under normal living conditions, concrete is less prone to sound transmission between floors.
How can I make my concrete floor quieter?

Is concrete more soundproof than wood?
Yes, concrete buildings are quieter than wood frame buildings —in most cases though. But sharp sounds like those from a shoe's heel can transmit to the floor below. However, under normal living conditions, concrete buildings absorb sounds better than wood frame buildings, even between floors.Nov 17, 2021
What is concrete slab?
A concrete slab is generally an asset for airborne sound isolation. The large mass (weight) provides for a great deal of sound isolation from vibrations entering or leaving the room.
What happens when sound waves hit drywall?
When a sound wave hits a panel like drywall, it starts a vibration wave in the panel itself. Vibration travels through a material as a “bending wave.”. Bending waves are only a phenomenon of solid materials, like in drywall. This is an Incident Wave.
How fast does a bending wave travel?
The speed of any vibration traveling through air (sound we hear) is a constant. Sound in air always travels at 768 MPH.
Why is concrete used in buildings?
Concrete is the standard building material for a reason. It’s sturdy and provides withstanding use over long periods of time. Concrete also boasts versatile properties that make it well-suited for many different environments and surroundings.
What is impact noise?
Impact noises are a byproduct of concrete’s rigidity, which transforms movement into an audible experience. While undesirable, these noisy manifestations can be eliminated with a few soundproofing measures.
Does concrete make a sound?
While many people choose concrete as their designated building material based on its hardness and durability, it’s this very quality that prevents concrete from improving acoustical performance. If you have a concrete floor, you may notice that every step produces an audible sound.
What is a dry screed board?
Dry screed boards represent a suitable alternative to wet screed systems, as the boards embody many of the benefits of a screed floor without the drying times. Typically manufactured from gypsum fibre the high density boards replicate a screed floor and are able to accept ceramic tiles directly.
Is airborne noise a problem?
Airborne noise is less of an issue as the mass of a concrete floor is able to absorb airborne noise transmission without the need to install soundproofing materials.
What is the best material to soundproof a carpet?
Rubber is a great soundproofing material as it absorbs sound and cushions footsteps. Mats can be fairly thin so they can easily take the place of, or supplement, traditional underlay. It is slightly inconvenient in the sense that you’ll have to lift the carpet before laying the matting. Once the carpet is up then laying it is fairly straightforward. You do need to ensure that they are cut to fit properly. If you squeeze a mat in it could cause a bulge or lump in your floor.
Why does sound get through my floor?
Even if you carefully soundproof your floor using one of the methods above you may find some noise is still getting through. This is because sound is transmitted wherever two surfaces come into contact. In this case, it’s where the walls meet the floor. This is known as acoustic failure. If you’ve added soundproofing but can still hear footsteps or furniture moving then this may be the cause.
What is green glue?
Green Glue is a company that makes a range of products including a soundproofing compound. It’s normally used between two layers of drywall and converts sound to heat to block noise travelling between two rooms. However, you can also apply the compound to the concrete floor before laying underlay, mass loaded vinyl or rubber mats on top.
Is concrete better than wood?
Concrete floors are much better than timber floors at blocking airborne noise but impact noise will continue to get through. If you’re finding it’s annoying you when other members of your family are moving around upstairs or you’ve received complaints from downstairs neighbours then soundproofing is a good idea.
How does a floating floor work?
Impact noise is transferred most when surfaces touch each other. Floating floors are made of interlocking panels with membranes affixed to the back. The idea is that the membrane forms a layer between the floor and the concrete sub-floor. This will prevent impact noise by stopping the two floors from touching. Noise is blocked before it transfers into the concrete. There is a range of products you can use for this. This is great as there are options to suit any budget. The most commonly used types of flooring that can be installed as a floating floor are:
Is mass loaded vinyl good for carpet?
If you’re prepared to lift your carpet, then mass loaded vinyl is another ideal choice as a supplement to your underlay. It is thin, flexible and both blocks and absorbs sound. When paired with carpet, this should reduce impact noise to almost nothing. Mass loaded vinyl is relatively inexpensive so if you’re on a lower budget it’s worth considering.
Is there an underlay for carpet?
Whether you’re laying carpet, laminate, or wood you’ll need to use underlay. If soundproofing is important to you, then acoustic underlay is available. The difference to traditional underlay is that it’s denser and therefore will block more sound. It is more expensive than standard underlay so you’ll need to see if your budget allows for it.
What is the best way to soundproof a floor?
If impact noise is having a negative impact on your life, using a sound dampening compound, such as Green Glue or a similar alternative, will help soundproof your floor. It should be used between two hard surfaces, so it’s best to add it to the existing subfloor before you place the underlay or hardboard.
What is floating floor?
Using a Floating Floor For Soundproofing. A floating floor is a separate floor that’s not glued or nailed to your subfloor. It sits freely on the floor below, allowing space for movement and vibration absorption. Floating floors sit on absorption pads and aren’t secured to the joists.
What is structure borne noise?
Structure-borne noise is created by vibrations, usually from the impact of objects on the floor. These can be footsteps, dragging furniture, vibrating appliances, or dropping something heavy on the floor. Dropping weights will create a LOT of impact noise. Unlike walls, floors are a major contributor to impact noise in buildings due to ...
Does carpet absorb sound?
Adding a rug or carpet (the thicker, the better) to your floor can make a huge difference as it will absorb sounds. A thick, firm carpet will absorb sound the best, but make sure it’s also comfortable to walk on. Carpet that covers the whole floor will dissipate any noise that gets through the floor.
Can you soundproof a basement?
If you’re just constructing your house or converting your attic or basement, now is the ideal time to soundproof the floor while your joists and subfloors are still exposed. However, it’s still very much possible to soundproof your floors—no matter what they’re made of—in a house or apartment that’s already built.
THINGS TO CONSIDER BEFORE SOUNDPROOFING YOUR FLOOR
When it comes to soundproofing a floor, there are two categories of sounds to worry about.
MATERIALS FOR SOUNDPROOFING YOUR FLOOR
We are getting closer to the sweet part – or not so sweet part. In this section, we are going to explore:
TECHNIQUES AND APPROACHES FOR SOUNDPROOFING YOUR FLOOR
The techniques for soundproofing a floor are more of a personal preference. Sometimes, it could be a result of building regulations. But for clarification, the techniques are ways you could go about soundproofing your floor.
CONCLUSION
If you’re considering soundproofing your floor, you need to decide whether you’ll be soundproofing below the subfloor or above it. You also have to research the types of materials you will need to soundproof the floor.
Why is soundproofing important?
Soundproofing is necessary for a variety of reasons, but some people. simply want a better living experience . Others might be trying to soundproof a room completely so that they can record, or enjoy the silence inside. A room made up of nothing but cement feels very dull by design and loud for people in it.
What is the goal of soundproofing a ceiling?
The goal in soundproofing a ceiling is to add a fair amount of material, but not so much that it severely shrinks the room. Something that is a very high mass with a ton of density works best.
Does concrete ceiling make noise?
With that said, there are still ways to soundproof a concrete ceiling properly.
Does cement make noise?
The hardness of the cement actually works against it, making a lot of noise on impact. The rigidly of concrete makes any type of movement above make a sound. It also reflects sound coming from other parts of the room, which could distract people from living the quality of life they are wanting.
Can you soundproof a concrete ceiling?
If the room has a concrete ceiling, chances are it very well could have concrete on the walls and floors. To get the most out of simply soundproofing a cement ceiling, there also needs to be work done on other parts of the room as well. Otherwise, similar issues are going to pop up.
What Types of Noise Can Concrete Soundproof Against?
Soundproofing A Room with Concrete
- To effectively soundproof a room, the materials used must have the following qualities: 1. Decoupling 2. Absorption 3. High Mass 4. Damping (Source: Soundproofing Company) Cement is known to have some of these qualities—absorption, high mass, and dampening, in particular—making it a suitable option for soundproofing against airborne sounds.
Absorption
- When the walls or floor of a room is made up of material with a lot of tiny air holes or spaces, it becomes easier for people in the adjacent room to hear you. This is because soundwaves will resonate within the air bubbles. Materials that are made to be soundproof are likely to be nonporous, or without or with few air pockets and holes; the less holes, the less sound that can …
High Mass
- Sound is only able to move through a wall if the wall slightly moves as the sound passes through. To prevent this from happening, you would need to use a material with more mass, such as certain types of concrete; just as there are cement mixes that have more air pockets, some are made up of heavier ingredients. However, note that using high-mass concrete would only be effe…
Damping
- The last quality that can make a material an effective sound blocker is damping. Damping helps reduce the amount of resonance (or vibration) in a room as much as possible. The vibration that is not removed from the air could potentially aid the transfer of noise from inside the space to the outside. It is worth noting that resonance can be removed via absorption (mentioned previously…
Soundproofing Alternatives to Concrete
- Regardless of whether you already have concrete floors or walls, sometimes that may not be enough to block all the sounds you want. For that reason, there are plenty of additional methods you can use to soundproof a room if the concrete isn’t doing it for you, including: 1. Acoustic Foam Panel 2. Wallpapers 3. Noise-Reducing Curtains
Final Thoughts
- Ultimately, if you want to block airborne or acoustic sounds, concrete is the material of choice. Its solid, uniform surface prevents sound waves from resonating within it for long by damping it. However, for maximum soundproofing, make sure you opt for nonporous, heavy cement. On the other hand, if you want to prevent the transfer of loud impact sounds or low-frequency noise, yo…
