What Is STC and Why It Matters
Hey homeowners, ever wonder why some walls block noise better than others? The secret is in something called STC, which stands for Sound Transmission Class. Simply put, STC measures how well a wall, door, or window can stop sound from traveling through. The higher the STC number, the quieter your space becomes.
For context, an STC rating of 30 might muffle a normal conversation, while an STC of 50 could almost silence the sound of a loud TV. These ratings are tested using different types of noise—from whispers to heavy street traffic—so you get a reliable measurement of sound control.
How Walls and Doors Affect STC
Think of STC as a sound filter. A standard wall usually has an STC rating of around 35, which means some noise will still slip through. If you add insulation or install soundproof panels, you can increase that number to 45 or more. That’s a huge improvement, especially if you’re trying to create a peaceful home office or bedroom.
It’s also important not to overlook doors. Hollow doors can leak a lot of sound, but replacing them with solid ones or adding a corridor can make a noticeable difference in your home’s overall soundproofing.
Simple Fixes To Boost Your STC Rating
The good news is that improving your STC rating doesn’t have to be complicated. Start by checking for weak spots like thin walls, gaps around windows, or lightweight doors. From there, you can apply simple, STC-friendly fixes to reduce noise:
-
Add insulation to your walls
-
Use soundproof panels or felt boards
-
Upgrade hollow doors to solid ones
-
Seal gaps and cracks around windows and doors
These upgrades are practical and effective, making your home noticeably quieter without a massive renovation.
