How to transform a door into a soundproof door

Just transform your door into a soundproof door, which is actually very simple.

The door panel is covered with a sound insulation board.

The door panel is covered with a sound insulation board. You can use mineral wool sound insulation board or other sound insulation materials, or you can go to the decoration shop for consultation. If you find it impossible to install sound insulation materials on one side, you can wrap sound insulation boards and sponges on both sides.

Use double glass or sound insulation material.

Windows are made of double glass, and the interlayer in the middle will reduce many decibels. If you think it's so troublesome, you might as well replace the window with a soundproof board.

Sealing of door crack

Fill the gap in the door with sponge or other sound insulation materials, and put more sound insulation materials on the door panel to make the door and the door frame fit together.

Price consultation

I suggest you go to a nearby decoration shop to inquire about the price, buy materials yourself, find someone or do it yourself.
