Soundproofing a room begins with soundproofing the actual door. In fact, this is where most of the sound gets out, so this step is the most significant in the process. There are multiple ways to do it, whether you only need to cover one room or you want to soundproof all internal doors in the house.
Get some soundproofing rubber
The more space you can see around the door, the more sound will leak out. If you have plenty of it, some soundproofing rubber will keep much of it inside. This type of rubber is usually based on neoprene – a denser option, though.
If there is moulding around the door, you need to remove it before carefully adding this soundproofing rubber. You may still have small gaps here and there – simply fill everything up with acoustical caulk.
If not sure where these gaps are, wait until it gets dark, turn the lights off in the room, and keep them on in the hallway. Pay attention to where the light goes through.
Weatherstripping does help
Even if you do use soundproofing rubber, there will still be gaps between the door and its frame. It makes no difference if you have internal oak doors or other materials. To feel these gaps, weatherstripping is probably your best choice.
Weatherstripping is normally used for external doors and windows with the primary purpose of protecting against weather conditions. You will also find more or less durable options out there. Make sure you apply plenty of pressure, regardless of what you use – this is what helps create an airtight seal.
Get a door gasket
This is the more expensive option – the more professional one. It is one step further from weatherstripping, and while it does imply a bit of extra work, it also guarantees for better results in the long run. Its main role is to fill all the possible gaps between the door and its frame.
Door gaskets normally go on the sides, but they also cover the top of the door. The goal is to come up with a durable seal. You will usually find gaskets based on neoprene – denser, but also more qualitative and durable.
Some door gaskets are adjustable. If your internal doors are based on wood, they can warp or expand over time. Plus, they may not always be perfectly square, so a bit of adjustability will prove to be very handy.
Get a door sweep
Closing gaps around the edges and the top of the door will not cause too many issues. You do have a few good options. But then, what do you do about the gap under the door? This is the part that raises the most question marks.
The sound will easily leak out under the door if you cover the rest of the door. You can add loads of panelling and gaskets, but if there is a gap under the door, they become useless. A door sweep will help you overcome this problem, though.
Internal doors UK do come with lots of space underneath. This door sweep will close the gap and prevent noises from leaking out. Get a soundproof door sweep. It may take a while to install it. You will probably need a drill too. However, the final result will not disappoint you.
Some door sweeps are automatic. An automatic door sweep will raise a bit when the door is open. When the door is closed, it will fall down and create a perfect seal.
Acoustic panels make the difference
All these steps will ensure a good soundproofing experience. You obviously need to tackle the problem from more directions. Go on the sides and the top, then fill the gaps. Then, you have to go underneath the door.
While results are worth your time, it may feel like there is too much work involved. What other options do you have then? Simple – acoustic door panels. Plywood attached to the door is one thing, while acoustic door panels are completely different.
You can also go for a fibreglass soundproofing blanket, but this option is a bit more expensive. Panels come in different materials. You can find foam, which is the most popular choice out there, but you can also find solid wood, which is just as good at reducing noise.
The result? Less noise and sound waves travelling through the door. You can glue them or use adhesive tape to avoid damaging the door. However, you can also nail them – longer lasting results, but a bit of damage on the door.
Acoustic panels can and will help, but small gaps between the door and frame will still let some noise out. Therefore, it pays off going through all these steps and preventing audio leaks from all directions to be more effective.
Conclusion
You do not have to be a genius to figure out how to soundproof a door. Finding doors with soundproofing capabilities from the beginning is more effective, but the steps mentioned above will help you adjust your current doors, meaning they are more cost-effective in the long run.
Soundproofing a door requires a bit of work, but it is not impossible. Once you upgrade your first door, the process will become much easier as you move on to the others. But then, even when everything is done, small issues may still arise if walls are thin, so think about this aspect too.

FAQs
Does soundproofing work on doors?
Soundproofing requires a good seal in order to work. If there are gaps between the frame and your door or between the floor and your door, it is obvious that sound will easily leak out. Fortunately, there are ways to fill these gaps.
What door material is best for soundproofing?
Hardwood is excellent for soundproofing because of the layered effect. Steel and fiberglass doors have similar effects and cost less than hardwood, but they are less likely to be as durable. In terms of soundproofing, there are not too many differences.
How does sound go through a door?
Sound is based on vibrations. When they hit the door, they transfer, and while they lose intensity, they go to the other side. Gaps around doors will also let vibrations pass through.
