How to Soundproof Between Existing Floors In 11 Steps

Not only you but every single individual is facing the issue of noise coming from their neighbors and the worst part is you can not complain all the time to your neighbors.

And if you are living in an apartment which has a number of floors up and downside of your apartment then it is worth reading this guide on how to soundproof between existing floors.

Here is a brief on how to soundproof between existing floors? place an additional layer of drywall on top of the ceiling using the resilient channel to create an air gap and with the help of acoustic sealant close all the holes and cover flooring using the thick carpet and underlayment.

But not to worry about it, as I already listed the number of ways through which you can solve this problem in a satisfactory cost-effective solution.

how to soundproof between existing floors

There is a couple of major area on your apartment which needs immediate attention such as flooring, ceiling, and small gaps to all different sides of the apartment.

The best part is this detailed guide has given complete solutions around all the areas with the best cost-effective affordable solution.

But first, you should be aware of the types of noise.

What are the Types of Noise

Mainly you will experience two types of noises and both can be overcome using the soundproofing materials.

Here is a major difference between both.

Airborne Noise 

You are familiar with the noise coming from the whispering, distance chat, TV, or music noise from the various areas that are all part of the airborne noise.

Airborne noise needs just a medium of air to travel a long distance and will not stop unless it found a strong barrier. So in order to tackle such noise is to set a strong barrier but how?

Already covered in this guide.

Structure Borne or Impact Noise

Have you ever heard a noise coming from footsteps or due to the fall of any object on the floor, that type of noise is known as impact or structure-borne noise?

In summary, the noise created due to the collision of two objects is known as impact noise. If still need more explanation then here is the best guide on airborne vs structure-borne noise.

This means, if you are living in the middle of the apartments you will get both Airborne and impact noise from upside and downside or in other words from the ceiling and flooring of the apartment.

Let me get you through the steps on how to soundproof between existing floors to avoid unnecessary noise in just 11 steps.

The Major areas which we will be focusing on these purposes are first flooring then the ceiling and later on some gaps which need immediate attention.

SoundProof Flooring in between Apartment

Most of the time when the noise coming from various sources especially the person living just below the apartment pass through the flooring and transmitted it to various areas of the room.

Flooring is the hardest surface in the house, which cause more reflection of the noise and will get amplified and create problem in your peaceful life.

So if you are familiar with the types of flooring then most probably we have two major types of floorings such:

  • Timber joist flooring
  • Concrete flooring.

If you are living in a ground-level apartment then obviously you should not be worried about any type of noise but this is not the case when living in between multiple apartments.

How to Soundproof Timber Joist Flooring

Let first discuss the number of ways through which you can soundproof the timber joist flooring as it is the source of both airborne and impact noise.

Wooden floor covering

Remember the key takeaway to make any flooring soundproof is to increase its mass or density, the higher the mass the less noise transmission.

Below are the ways you can use soundproof timber joist flooring.

Use of Underlayment

Underlayment is the material used just below the sub-flooring or below the top floor covering. It increases the density of the flooring if your floor is made of plywood plank or timber.

Underlayment should be thick enough to lay just below the top covering so if there is any impact on the top of the floor that got absorbed by the underlayment.

Floor underlayment

Underlayment not only offers noise absorption but is also a strong resistive to moisture. It also adds evenness to your uneven floor covering.

If your flooring is laminated flooring then use of the underlayment is most recommended.

Use of the Thick Carpet or Rubber Mat

Carpet plays an important role in increasing the thickness or density of the existing flooring as the use of underlayment could be an expensive solution.

Soundproof Carpet for noise absorption

The carpet will be used just above the surface of the flooring and will create a strong blocker for the noise coming from the other side of the house.

But if the use of carpet is not effective then head over to the most favorable sound dampening material rubber mat.

A rubber mat will dramatically improve the ability of flooring to absorb the noise coming due to airborne or impact noise.

 Use of the Drywall

Ideally, the main purpose of using drywall is to either wall or ceiling but if you need the best result of floor soundproofing then it is all up to you, how you can place drywall just below the floor covering and carpet.

Again drywall is dense enough and creates a strong blocker for the noise.

Let’s focus on the other area what if you have concrete flooring and how to deal with that.

How to soundProof Concrete flooring 

The best part with concrete flooring is we have to deal with only airborne noise as the impact noise or the noise due to squeaky shoes will not be the case with concrete flooring so how to deal with the same.

The solution is easier and cheaper as we don’t have any major maintenance with the existing floor.

Use of Acoustic Mat or Carpet

Here the purpose of the mat or carpet is to increase the sound-absorbing capacity of the flooring. As ceiling and flooring are the major areas from there the sound gets reflected.

By having a concrete floor you will definitely be having an issue with sound absorption due to complete hard surface, so use the acoustic mat or carpet all over the flooring is the cost-effective solution.

Use of Drywall

Mat and carpet will be an affordable solution to soundproof flooring but the use of drywall will be the most efficient solution.

While placing drywall over the flooring make sure to have space for at least an inch.

This will not only reduce noise transmission but also help you maintain the room temperature low especially in the summer season.

If you are really keen on soundproof flooring then I strongly recommend reading the complete detailed guide,

Must Read: how to soundproof flooring

No matter you are living between the floor or wiling to soundproof basement flooring, this is a really helpful resource.

Let cover the other area of the apartment ceiling and how to soundproof between the existing floor.

SoundProof Ceiling in between Apartment

Probably floor soundproofing can be achieved without more hassle as you have to buy a few things which you can fix immediately but ceiling soundproofing is the most tricky job.

In order to the soundproof ceiling, you have to focus on below major areas as it not only a source of the airborne noise but also the impact noise.

Both the noise in case of the ceiling are very irritating as the people are living above your floor and at which point of time what they do you will be the victim of all kinds of noise.

So below are the best possible affordable suggestions.

Cover the Ceiling with Additional layer of DryWall

Mainly ceilings are made of the timer joist which has more often impact noise due to footsteps or of any object fall on the surface and also some airborne noise due to TV or any musical instrument.

Hence the major area to focus is to increase the width of the ceiling by adding the additional layer of dense material and drywall is the first and most recommended solution in this list of soundproofing.

SoundProof Drywall

Drywall should be placed with a gap of at least 1 inch and that can be achieved using the resilient channel which creates an air pocket of at least 1/2″.

This air pocket will trap the noise coming from the top floor and noise energy will be weakened and when it tries to pass through the drywall layer it will again attenuate. Make sure the use of drywall can reduce the ceiling size up to 4-6″.

But use the acoustic drywall, not conventional drywall if not familiar with both then must go through the detailed guide on soundproof drywall.

Use the Mass Loaded Vinyl

Mass loaded vinyl is the most recommended solution to block the noise as it has the great mass to width ratio means you can achieve very high insulation by placing a layer of MLV on any material.Mass Loaded Vinyl -MLV

If you have added drywall then even the chances are there that noise will try to pass through the ceiling, so now the next step is to cover the top layer of drywall with MLV which is available in various colors.

It will create a strong barrier for noise and chances of noise to pass through MLV will be very less, must-read what is MLV and how MLV can solve your problem of soundproofing no matter is floor or ceiling.

Use Acoustic Sealant

The ceiling might have some area that needs immediate attention, such as if any electrical cable coming from the top side of the apartment or any holes left at the joints of the ceiling.

Acoustic sealant

Like air, noise can even pass through those small holes without a doubt. So focus on that small area and seal them with the acoustic sealants which are flexible in nature and will not harden and broken in a few days.

If keen to learn which acoustic sealant will be the perfect solution then don’t miss the chance to guide first on best soundproof sealant that will help you to not break your hard earn pocket money.

Bonus Tips on Soundproofing between floors

It is common that no matter what changes you do with ceiling or flooring, you will not see a 100% reduction of the noise and if noise enters the apartment then obviously reflection.

So try below things in addition to the ceiling and floor soundproofing.

Add some additional soft materials in the apartment

The best way to reduce noise reflection is the sound absorption and this can be achieved using the soft materials so add some sofas, curtains, and books to the area.

Soundproof door and window

Cover the flooring with the soft carpet and also use the anti-vibration mat below the washing machine to avoid vibrations in the complete home.

Here is the top list of best sound absorbing materials you can try.

Use Acoustic Foam

If having your own studio and want to absorb the echo within the room then head over to the best acoustic foams, they will offer the best sound-absorbing ability. 

Pyramid Acoustic Foams

Acoustic foams are of various types and you can use them over the walls with sticky glue and can get amazing results in noise reduction.

SoundProof door or window

After ceiling and flooring, the other area which causes most of the reflection is the door or window. Most of the time the door will be closed and the only way through sound can transmit is the gap left between ground and door.

SoundProof Door Sweep

To avoid noise transmission just below the door you can block that space using the soundproof door sweeps.

With respect to the window, you need to place an additional layer in between the window surface and noise coming after reflection from various areas.

This can be achieved by placing the acoustic curtains which will create strong blackouts and absorb most of the noise. Here is the list of the best collections of soundproof curtains.

I know it is tough to live in between the existing floors but the solution to overcome noise will always be there.

If you are living in a house that has no floor then still you face an issue of noise coming from the walls if you have noisy neighbors, so here is the best way on how to soundproof wall from the noisy neighbours.

My Tip How to Soundproof Between Existing Floors

Always focus on increasing the density and mass of the materials which separate your apartment from the top and bottom side of the apartment.

If the case is ceiling then drywall with a mixture of MLV will be the best effective solution and if flooring then uses underlayment and cover the flooring with an acoustic mat or carpet can really give the best results.
