Therefore, affecting your soundproofing methods. This can cause the neighbors or those you live in the house to start complaining.

I am sure you don’t want that and that is why you are looking at ways to block the sound from leaving the room through the door.

The way to soundproof the frame is to apply the acoustic caulk in between the layers of the door frame and drywall/cement. The caulk will completely seal the gap and prevent any sound from leaking through.

I used this Acoustic Caulk at Amazon and  I also had to get a Caulking Gun because it was my first time, I didn’t have a caulking gun already at home.

Acoustic caulking the door frame is an inexpensive way to soundproof your home theater doors frames.

2. Seal the Door Jambs

The vertical framework that ensures your door securely held is the door jamb. With a small gap in between the door and the jamb, sound can easily pass through.

Most doors have this gap just to prevent the door from scratching the floor. Because of that, there is a lot of noise that gets in and out of the room through this gap

Soundproofing this door gap is possible and it will help a lot. because it was a home theater and I did want to ensure the isn’t sound leaking in any way, I got the Automatic Door Bottom instead of the Door Sweep.

Of the two, I believe the automatic door bottom is better, but if you are on a tight budget, then get the door sweep.

4 . Add a Mas Loaded Vinyl to the Door

Adding mass to the door itself is a good way to absorb the sound or dampen it. Sound can easily pass through a hollow door compared to a solid one.

But in this case, we are trying to soundproof an existing door that is not soundproof. Since we do not want to remove the door and still a soundproof door, we can add extra soundproof mass to it to help in the sound absorption.

A mass loaded vinyl mat is an effective soundproof material that helps in absorbing sound. It is a high-quality vinyl barrier that can also be used to block sound between Walls, Ceilings, Floors, Automobiles, Machinery, Pipes, HVAC and more.

You cut this soundproof material to fit the size of the door you want with a household knife or a pair of scissors and you can either use green glue to glue it to the door or staple it to the door.

Most mass loaded vinyl mats are black by color. This might make the door to now look black. adding a soundproof curtain or drape to cover it up.

Vinyl mats are good at reducing noise but are quite expensive compared to other soundproofing methods.

5. Add Drywall on the Door

Adding an extra layer of drywall to the door will help in reducing the sound. for extra reinforcement, adding an extra layer of drywall to the vinyl mat will help.

Drywall is a good soundproof material for dampening sound. If after installing the vinyl mat, you can install the drywall on top of the vinyl mat.

6. Foam or Rubber Tiling

You can add an acoustic foam panel to the door. Foam panels are effective at putting noise at bay and are cost-effective too.

Alternatively, the rubber tile can also be glued to the door with green glue or staples. Although they are not foolproof at soundproofing, when used in conjunction with other soundproof materials, then better results are achieved.

A local hardware store or music supply store may have specialized interlocking tiles that you can attach to your door using Green Glue or staples. These acoustic tiles usually have different noise-reduction levels, so make sure you choose the highest level available for the most sound blockage.

7. Hang Soundproof Curtains

If you really want to make a dent in the sound entering or leaving the room, you will need to invest in industrial-grade soundproof curtains.

I know what you are thinking—curtains are for windows, not doors. However, these specific soundproof curtains are designed to keep noise away and are equally effective when used on a door.

To install them, you install the curtain rod like you would for a window above the door frame. From there, you would just hang the soundproof drape on it, just like you would a standard window. Be sure to get the curtain that will cover your entire door.

This is a solution I feel is worth looking into if you really want to avoid the hassle of replacing the door. It is also much more cost-effective!.

7. Hang Soundproof Blanket for Door

Another option for soundproofing a door for those who live on rental properties and not want to spoil the door is using a soundproof blanket. Simply hang it behind the door using a couple of hooks.

Soundproof or moving blankets are usually made from an absorbing material, such as fiberglass, which is perfect for sound absorption. Heavier soundproof blankets can almost absorb most sounds.

but if you are looking for aesthetically appealing in the room, then these blankets might not look visually appealing. You might want to hang them if you don’t really care much about hoe the door look.

curtains give you the flexibility of choosing nice colors to fit your room decor, unlike the blankets.

8. Change Your Hollow Core Door to Solid Core Door

There about three main types of doors. There are namely; hollow core doors, solid wood doors, and solid core doors.

Hollow core doors are the doors you mostly find in homes and apartments. There are doors are the least expensive and that is why most house owners use them to cut cost.

The downside of these hollow core doors is that they are very prone to sound leakage. They can contain a lot of air in their core. This makes them a medium for noise pollution.

If you have such a door in your home theater and don’t want to change to the solid core door, then you have to follow these techniques I used above to soundproof the door.

This way, sealing all the gaps and adding mass to the door, you will achieve a good level of the soundproof door.

However, the best way to soundproof a door is to replace it with a solid core door.

What Type of Door is Best for Soundproofing?

Of the three types of doors, the type of door that is best for soundproofing is the solid core door. Their solid core is made with a composite material which is a very good soundproofing material. The other type of soundproofing door which is better than a hollow core door is the solid wood door.

Soundproof Doors

Solid Wood Doors – Solid wood doors are made of a combination of natural wood elements that have been put together.  These doors look good but they don’t necessarily provide a complete soundproof door.

These doors are quite heavy and therefore provide decent soundproofing. They also look great in any type of room. However, they are quite expensive.

Solid Core Doors – Solid core doors are just as the name implies; they are doors that have a solid core made with composite material. Because their cores are denser and heavier than solid wood doors, they make for the best option for soundproofing a room.

In your search to replace your hollow core door with either a solid wood door or a solid core door, you will need to understand the terminology used in rating soundproofing materials. It is called sound transmission class (aka STC).

You will often come across it when you embark on soundproofing projects like this. It is simply a rating that tells you how well a building element reduces airborne common sounds. The higher the STC of soundproofing material, the better it will be at blocking out sound or it will be a better soundproofing material.
