About Interior Door Sound STC Ratings
The STC ratings are the most used and widely recognized means of comparing acoustic performance of home construction products. This rating measures the amount of of sound loss through any given door. The higher the STC number, the less sound will pass through the door. This rating mostly depends on the door's materials. However, there are also some small additions that can be made to improve sound suppression.
Generally, a less soundproof door, such as a hollow core door, is given 20 for an STC rating, which means that most conversation-level speech will still be heard when the door is closed. With a thicker interior door, such as a solid core interior door, STC ratings of 35 are standard. For a truly soundproof door however, homeowners should look for an STC rating of between 55 and 60. A solid wood door tends to be the most soundproof door for your home's interior.

Most interior doors are made with a cost-efficient hollow core. Again, because of their hollow core construction, these doors' sound qualities and design are similar to those of a drum, which makes them ineffective at blocking sounds.

According to the NWWDA, if a homeowner replaces a hollow core door with a solid core door and weatherstrips the door's perimeter, the resulting product would most likely have a high STC rating of 34 to 36.
