Hinged doors will often give you the best results in this area. In many cases, it may be possible to arrange doors along a hallway so that they swing without transmitting noise to adjoining rooms. Of course, you can always replace an existing door with one made of a tougher material. If your interior doors aren’t exactly noise-canceling, there are a few steps you can take to make them a bit less sound conductive. Another option is to get a prehung door, as these have hinges already in place. And if you’re not up to doing these tasks yourself, this is a good time to call a professional. Keep in mind though, that a heavy door, such as the wood slab variety, may need longer, sturdier screws to reinforce the hinges.įor ill-fitting doors or odd-sized openings, you may need to make some modifications, such as trimming the door or outfitting the door jamb with the new hinge and strike-plate mortises.

So, replacing a hollow core door is the first step in minimizing sound conduction. It’s no wonder that solid wood slab doors are much more up to the task. By the way, in case you’re wondering why hollow-core doors are so inadequate at resisting noise transmission, it’s because their cores are made of a cardboard honeycomb material. Doors play a critical role, too, although they’re a weaker link when it comes to muffling sound. Too often, the drywall layers in walls and ceilings are too thin to block sound. When you have a double layer of 1/2-inch drywall, which adds up to four layers in total, and 3.5 inches between them are filled with insulation, it has an STC rating of 45.When a standard interior wall has 1/2 inch drywall and the 3.5-inch space in the middle is filled with insulation, its rating goes up to 39.If a standard interior wall has 1/2 inch drywall on both sides and 3.5 inches of airspace, its STC designation is 33.A solid door with particle-board core rates at 30.An interior hollow core door has an STC rating of 20 to 25.Now that you know a little more about the kind of sound barriers created at various ratings, let’s consider the ratings of common wall and door materials. Most of today’s homes are equipped with hollow core doors, which are the least sound-resistant. Anything that interrupts the wall’s continuity, such as a door, allows even more sound to be transmitted. When walls are thin, sound pours through them.

At STC 30, you can hear normal speech but not understand it.You can clearly understand normal speech at STC 25.Here are some common STC ratings and what they mean. The higher the rating, the better the material minimizes sound transmission. Sound class transmission ratings (STC) ratings refer to the acoustic performance of doors, walls, and other materials. Sliding doors made with laminated glass provide additional security because they’re a lot harder to break. Most sliding doors come with tempered glass, so they can break easily if an intruder wants to quickly gain access to your home.
