Best Methods to Soundproof Your Door


While locked doors do an excellent job of blocking out noise from outside the room, cracks between such a door and its casing or threshold allow some sound to pass through. To successfully seal these holes, you’ll need to mix and combine a few different tactics.

If you secure all of the spaces and surfaces described in this tutorial for how to soundproof a door thoroughly, you’ll obtain the best soundproofing possible.

Determine your space’s requirements and check whether it’s just enough noise to fall asleep or perfect silence for your underground recording studio. You can read the following methods to know how to soundproof your door.

Then you can choose one of the following approaches.

Method 1: Use Spring-Metal Strips

Install new spring bronze weatherstripping to improve the door seal and prevent noise from penetrating through the cracks. This sort of weatherstripping does the same job as standard vinyl or stick-on foam weatherstripping, but it does so more effectively and for a longer period—up to 30 years. It’s incredibly beneficial for outside doors, which must be dependable in terms of keeping water and bugs out.

Method 2: Use Rubber Weatherstripping

Rubber weatherstripping, similar to metal weatherstripping, is intended to seal and eliminate not only draughts but also noise. While there are a few various types of rubber weatherstripping offered, the one with adhesive backing is the easiest to use.

Method 3: Substitute a New Threshold

Daily traffic may weigh down or weaken your pre-existing threshold, which is the raised section of an entrance that helps conceal the line where the floor meets between rooms while isolating sounds. Adding a better threshold, which you may obtain at your local home improvement store, will keep unwanted noise out of the house.

Install an MLV Sound Barrier

For individuals seeking tranquility, a mass-loaded vinyl (MLV) can provide significant soundproofing. MLV hanging on the back of the door considerably lowers the noise that would otherwise pass through, despite its common use as a vibration cushion beneath the carpet.

The thickness ranges from 1/16 to 14 inches, with thicker being preferable for sound absorption. If the thickness of a product isn’t specified in the description, you can rely on the weight per square foot of coverage:

  • MLV is 1/16-inch thick in a half-pound bag.
  • MLV is 1/8-inch thick and weighs one pound.
  • MLV is 14 inches thick and weighs two pounds.

Before you begin this soundproof endeavor, enlist the help of another do-it-yourselfer to hold the flexible foam pad in place.

Final Thoughts

Now that you realise how to soundproof your door, you should also know that it has the added benefit of providing thermal insulation. Many soundproofing tools and materials also protect your space from severe temperatures. As a result, your freshly soundproofed space will cost less than a heating and cooling system.

Soundproofing your door can also aid your room’s air quality, humidity, and comfort. Sealing the door keeps pollutants and moisture out, making the space more pleasant to work in or rest in. Follow the best methods for sustainable results.
