The benefits of a quiet room are well established. Peace and quiet greatly enhance the productivity of your work and sleep.

As a homeowner, what can you do to ensure your room has the soundproofing qualities needed to be your best?

A good place to start is your doors.

Hollow core interior doors are often the biggest source of noise infiltration into most rooms in a home. They lack the mass needed to absorb sound.

This article will guide you through the various options you have to upgrade to the best soundproof doors for your bedroom or home interior.

STC for Soundproof Doors & Your Needs

Before searching for a new door, you should know how much sound you are trying to block.

Use a decibel meter, or an app on your phone (less accurate) to determine the dB at the source. Then look at the dB chart to see what level of sound you want to achieve in the receiving room.

Subtract the two and you’ll get a target STC rating for your new soundproof door.

In this list, we’ve outlined the Top 10 options you have for soundproof interior doors.

The first three can be ordered at your favorite big box home improvement store.

1. Solid Wood Slab Doors – Best for Bedrooms

If you were to ask homeowners which single door they would love a solid wood, the betting money is the master bedroom. A home office will be another popular answer with the rise in Work from Home. For privacy, peace, and quiet it’s hard to beat a solid wood door!

Overall, solid wood is good at soundproofing because it’s porous, which means that it has air pockets that can help trap sound. This is one of the reasons that solid wood was the door material of choice for hundreds of years.

Solid wood also has the benefit of being warm and lovely in its appearance. You can’t go wrong with solid wood doors for your home’s interior, whether your home is contemporary or classic.

  • Wooden doors come in a range of styles and finishes, so you can choose the color that appeals to you.
  • Unique grain markings make each door unique.
  • Wood can easily be painted or stained, to match the interior of your home.

Solid wood adds a touch of class anywhere in the home, especially the master bedroom and home office. See some examples of solid wood doors at Home Depot.

2. Solid Core Doors – Most Economical

Solid core doors look so like solid wood that it’s sometimes hard to tell the difference. Solid core doors may have a wood veneer on the outside, and a solid core that traps sound.

The advantage of solid core doors is the cost – they’re more economical than solid wood but give good performance.

Each door varies by weight, but a typical weight for a solid core door is about 55 pounds – versus around 60 for a solid wood door.

  • Most solid core doors are easy to paint.
  • Many solid core doors are indistinguishable from solid wood, but for a much lower cost than wood.
  • Weighty doors add value to the house without breaking the bank.

Preparing to Replace Interior & Bedroom Doors

When you’re replacing a hollow-core door with a sound-blocking door, remember that the weight of the new door will be much greater than the original door. This difference is significant. It’s particularly important to make sure the hinges, screws, and wall studs are up to the task.

If you’re re-using old screw holes and hinges, be sure that the screw holes are a tight fight with the screws, and that the hinges can hold the weight of your soundproof door. When in doubt, replace old hinges with new ones or you may later be fixing an annoying squeaking door from the stress.

Soundproofing vs Replacing Your Existing Door

In some cases, replacing your old door may not be necessary. There are many things you can do to dampen the sound coming through a hollow-core door. Below are some steps you can take to reduce the amount of sound heard through your door:

  • Seal the Door Jamb – Install weatherstripping around the door to dampen the sound coming around the door between the door and jamb.
  • Seal Under the Door – Install a soundproof door sweep on the bottom of the door to seal the gap between the door and the floor.
  • Add Mass to the Door – Install sound-deadening fiberglass sheets, fiberboard mats, or mass-loaded vinyl to add mass to the door.
  • Hang Sound Barriers – Hang a blanket over the door to act as a sound barrier, preventing sound from coming into the room.
