How to Soundproof a Door

When you think of soundproofing any room in your house, office or anywhere else, the first thing you’ll start with is the door.

Soundproofing a door is the most important factor because doors are a major culprit in letting noise in and out.

If air can pass through the door, so can the noise.

There are many soundproofing techniques for a door; it all depends on what your budget allows you to do.

This article is all about discussing some simple techniques for soundproofing a door.


1. Fill in all the gaps

Usually, doors and windows have gaps you might not notice until you look for them.

These gaps are a very big source of letting noise in and out of the door.

Usually, you notice these gaps between the door and the door frame.

You need to seal all these gaps using weather-stripping tape, easily available for soundproofing.

The good part is you don’t have to call any expert to do this task for you; you can easily do it alone.

So this makes the process more budget-friendly because the weather-stripping tape is also not expensive.

Make sure you fill all the gaps to make your door fully soundproof.

I have a technique for you if you can’t see any gaps.

Shut down all the lights and make your room dark; now, notice if you see any light coming in from any part of the door from the outside.

This will make it easy for you to figure out the gaps.

2. Door sweep

You must have noticed there’s normally enough space under the door that may allow enormous noise to enter the room.

This gap is between the floor and the door.

To soundproof your door, you need to block this gap to block all the noise.

For this purpose, a door sweep can be used.

It’s easily available and can be installed easily.

Some door sweeps can be attached with the help of a drill and nails.

You’ll find some of them attached under the door using glue.

A door sweep is one of the best and cheapest ways to block enormous noise.

Along with blocking noise, a door sweep will also block all the dust and unwanted particles from entering your room.

And again, this soundproofing technique will also not include labour payment because you can do it yourself.

So this makes it cheaper.

But remember, a single technique would never be enough to make your door soundproof.

You must always combine two or more techniques to make it work.

If you don’t fill the gaps but attach a door sweep only, this will not make your door soundproof.

Noise will still keep entering your room through the door.


3. An acoustic door sweep

You can also install an acoustic door sweep.

This type of door sweep has a concealed flat-spring mechanism that controls the door sweep’s movement.

It functions so that when the door is opened, the sweep stays above the level of the floor.

When you shut the door, the sweep drops down, forming a tight soundproof seal with the floor to block all the noise from coming in.


4. Door gasket

Adding a door gasket can be expensive to make your door soundproof.

Using weather-stripping and soundproofing rubber is cheap, but a door gasket is a more efficient way of soundproofing a door.

A door gasket is attached permanently to the top and the sides to give your door a long-lasting seal.

Another option is to purchase an adjustable door gasket so that you adjust your gasket to get a perfect fit for your door.

This is because sometimes doors warp or are not in perfect shape.

So an adjustable door gasket is a good option.


5. Acoustic panels

Using acoustic door panels is another good option.

They absorb most of the noise in your room through the door.

The amplitude of the sound waves is reduced to make your door more soundproof by them.

The good part is you can nail them easily on the door without needing the help of an expert or a professional.

And if you worry that nailing them on the door may damage your door, you can always use adhesive strips that will not cause any damage to your door, nor will it destroy the look of your door.

These acoustic panels come in various materials, like foam and solid wood.

You can choose whichever suits your door the best.

Also, using acoustic panels for soundproofing is not an as expensive solution as fibreglass soundproofing blankets.

6. Adding door threshold

Consisting of neoprene with rubber protrusions, thresholds are better for soundproofing a metal door.

Thresholds are attached to the floor of the doorway.

They are not like door sweeps that are attached to the bottom of the door.

It will be difficult to have a threshold if you have a carpeted floor, even the best if the door sweeps can’t work properly on a carpeted floor.

This is because thresholds and door sweeps cannot perfectly seal a door when there’s carpet at the bottom.

Some thresholds are flat, while others extend upward, forming a double seal with the door sweep.

7. Soundproofing blanket

Using soundproofing blankets is an excellent option for making your door soundproof.

These blankets ate easily available, but they may be out of your budget.

They’re a bit expensive solution because they’re typically made up of fibreglass.

But one good thing about them is they are easy to install, so you’ll not need any help from a professional or an expert.

Simply get the soundproofing blankets and install them yourself.

To install them on the door, you just need to attach suction hooks at the back of these blankets and hang them on the door.

So simple as that!

Also, you can take them off easily and hang them again whenever necessary.

You should use them on a metal door if you want them to work at their best.

But that doesn’t mean you cannot use them on a wooden door.

You can.


8. Mass Loaded Vinyl

Mass Loaded Vinyl is one of the best options you have for soundproofing.

They are not only used for doors but they can also be used for windows, floors, walls, and ceilings.

You’ll get the best results when using it to soundproof your door.

Just buy a sheet of Mass Loaded Vinyl, cut it to the size of your door, and simply attach it using adhesive strips.

So, again you’ll not have to bear the expense of any professional; you can easily do it yourself.

The only drawback is that these Mass Loaded Vinyl sheets may not seem aesthetically appealing but they are very effective.

So in situations where utility is the key, you should never hesitate to use these sheets.


9. Soundproofing composite material

You can install soundproofing composite material for your door.

It can be easily installed under, inside or outside the door.

It helps dampen and absorb most noise, so your door becomes soundproof.

Also, it does not allow noise to pass through the door installed inside or outside the door.

If you place it under the door, make sure you place it exactly under it and don’t leave any gap.

The sound may still pass through the door if a gap is there.

It can also be used under the door as a doormat.

And to attach it to the door inside or outside, you may glue it easily with the door.

Another option is purchasing a door with a soundproofing composite material inside.


10. Fill the door with the sand

Filling the door with sand may not seem a practical soundproofing technique to you, but as unpractical as it sounds, this technique is very effective.

It may cost you a lot of time and hassle if not money.

You need to fill a hollow door with sand properly and then ensure the hinges you use to install the door should be industrial strength.

If you use weak hinges, you might end up ripping the hinges right out of the door frame because of the heavy weight of the door.

And only if you pay proper attention to the installation technique, your sand-filled door would stop the noise better than anything else.

I’m sure you will be very happy with the results.

It is one of the cheapest ways of soundproofing your door, but it might require a lot of work, and you might also need help from a professional.



When you think of soundproofing any space, a door is the first and most important thing you should start with.

Soundproofing a door may not cost you too much, and it might not require much work, time, and effort.

But still, it all depends on what technique you opt for soundproofing.

The above article discusses some simple, easy, and cheap techniques.

You’ll get the best results when combining two or three techniques.

Happy soundproofing!
