Most noise leaks through the door, not the wall.
If your room lacks privacy, your door is the first place to fix.

This guide shows the easiest and most effective door soundproofing methods.

Why doors leak noise

Typical doors have:

• gaps around the frame
• a large bottom gap
• hollow cores
• poor seals

Sound travels through any air gap, no matter how small.

Install a Door Seal Kit

This is the most effective upgrade.

Includes:

• perimeter seals
• automatic door bottom
• adhesive strips

Benefits:

• reduces noise leakage
• improves privacy
• affordable
• easy installation

Add a Door Sweep or Automatic Bottom

The largest gap is always at the bottom.

What to install:

• automatic door bottom
• rubber sweep (budget option)

Improve the door itself (if needed)

If the door is hollow, it will never block noise well.

Upgrades:

• change to solid-core door
• add mass (sound blankets or thin MLV layer)

Seal the frame edges

Use:

• acoustic sealant
• weather stripping
• rubber gasket tape

This stops sound flanking around the door.
