Sometimes, a cow only wants to chew its cud and ruminate in peace. But with dogs barking, babies shrieking, taxis honking and stereos blaring, what’s a poor city-bound bovine to do?
When many people think of soundproofing, they think of a high-tech recording studio that eliminates every whisper of background noise. But soundproofing is helpful in many areas of everyday life. Whether you live in a noisy building, want to be free to use your radio and TV at full volume without disturbing the peace or need a peaceful place to concentrate and relax, soundproofing can help make life much quieter and more comfortable.
Studies have found strong evidence that reducing noise pollution has beneficial effects on our health, decreasing our risk of heart disease, diabetes and more. One study found living by a noisy road correlates with a 25% increase in cases of depression, so finding ways to reduce noise pollution is also critical to our fundamental well-being, as well as to our comfort and happiness.
If you plan to soundproof a room or two in your home, don’t forget to noise-proof a door. That’s where the bulk of the sound leaks out, so soundproofing the door is particularly critical. Below, we’ll discuss some benefits of soundproofing a door and offer some helpful tips on how to do it.
Why Soundproofing a Door Is Important
Doors often contribute the most to noise issues, making them an essential element in any acoustical treatment.
The largest gap in a wall — and weakest link for soundproofing — is a doorway. Often, the space around the door leaks noise. And the space at the bottom of the door is often a much larger gap than the space around the sides, so it allows even more sound to leak through. Adding to the issue is that most interior doors have a hollow core. While this makes them more cost-effective, it causes more noise problems. Even the mechanism of the doorknob can admit some sounds.
Soundproofing your door helps address all these issues.
Soundproofing a door also provides a helpful ancillary benefit: temperature insulation. Many of the tools and materials used for soundproofing also provide insulation from extreme temperatures. So your newly soundproofed room will likely also cost much less to heat and cool.
Soundproofing your door can also help improve the air quality, humidity and comfort in your soundproofed room. Insulating the door helps keep out pollutants and moisture to keep the room comfortable to work or relax in.
A soundproof door is essential in several situations.
- You work from home: If you work remotely and need to concentrate, especially when you have a tight deadline, a soundproof door can be a lifesaver. If your work involves sound recordings or creating videos, a soundproof door is almost essential. But barking dogs, yelling neighbors, honking traffic, crying children — and, yes, even mooing cows — are all distractions that can get in the way of your work. A soundproof door helps you shut out the outside world and focus on what you need to do. Studies have shown that when a workplace removes conversational distractions — the noise of human speech — productivity increases by 48%, and stress symptoms decline by 27%.
- You have noisy neighbors: Nothing puts a damper on an otherwise ideal living setup like noisy neighbors. If you can hear your neighbors yelling, playing instruments or blasting their music at all hours, a soundproof door is a fantastic way to help give yourself some much-needed quiet.
- You are the noisy neighbor: If you play an instrument, blast your music, use your TV game at top volume or have to use sound features when you work from home, consider soundproofing your door. That way, the neighbors can enjoy peace while you work, rehearse or have fun.
How to Soundproof a Door
Complete door soundproofing requires extensive alterations to the existing door frame and labor-intensive construction. The weight of the door and its assembly can range from 300 to 500 pounds. Investing in a solid-core door or an acoustically rated door is also prohibitively expensive for many budgets.
So how do you soundproof a door? Below are some cost-effective, alternative ways to soundproof a door that will save you time, money and energy.
How to Get a Soundproof Interior Door
Most interior doors have hollow cores that admit substantial amounts of noise. To solve this problem, try some of these tips.
- Add a wooden panel: If you don’t mind a small home project, you can do this yourself. Go to the hardware store and buy a large, smooth sheet of plywood of about the same size as your door and at least half an inch thick. Cut a hole in it at the spot where the doorknob will need to fit through. Apply strong glue to the back of the plywood sheet, and press the glue side of the sheet firmly against the door. Use wood screws to attach the plywood to the door. The screws will keep the plywood securely in place to absorb sound.
- Add soundproofing rubber: If sound can leak around the sides of your door, consider adding soundproofing rubber to the perimeter. Soundproofing rubber is typically a dense form of neoprene — the same stuff they use in wetsuits to insulate against the cold. If your door already has molding around it, you’ll need to pry it off. Then, add the soundproofing rubber around the door’s edges. Add acoustical caulk or an insulating sealant to fill in small gaps and cracks to add even more sound protection. If you’re wondering where the cracks are, turn off the lights in the room and see where light comes in from outside.
- Add weatherstripping: If you’re putting up soundproofing rubber, you’ll also want to fill in the gaps between the door and the doorframe. One of the easiest ways to do this is to use weatherstripping, commonly used to insulate doors and windows from the elements. Basic weatherstripping tends to degrade over time, but you can buy higher-quality varieties for long-term soundproofing. When you use weatherstripping around your door, remember to apply enough pressure. The pressure is what allows an airtight soundproof door seal to form and impede sound waves.
- Add a door gasket: Door gaskets are a bit more expensive, but they are also typically a step up in quality from weatherstripping. Like weatherstripping, a door gasket helps fill in the gaps between the door and the door frame. Door gaskets attach permanently to the sides and top of the door jamb to provide a quality, long-lasting seal. Like soundproofing rubber, they often consist of high-quality neoprene. You can even purchase adjustable door gaskets — since doors sometimes warp or are otherwise not perfectly square, being able to adjust your gasket to get the best fit is a helpful feature.
- Add a door sweep: This step is crucial for closing the sizeable gap that exists at the bottom of many doors. You can add all the gaskets and paneling you want to your door, but if there’s a gap at the bottom, enormous amounts of sound will still leak through. To prevent this from happening, install a door sweep on the bottom of the door to close the door gap and impede sound waves. Soundproof door sweeps take some work to install — you’ll need a drill and screws — but the immense improvement in soundproofing is often worth it.
- Add an automatic door sweep: You can even install an automatic door sweep. This kind of door sweep has a concealed flat-spring mechanism to control the sweep’s movement. The sweep stays above the level of the floor while the door is open, but drops down when the door is closed to form a tight, soundproof seal with the floor.
- Use acoustic panels: If adding many soundproofing elements to your door seems like too much work, try adding an acoustic door panel. These panels offer a step up from gluing a sheet of plywood to your door, but they’re not generally as expensive as high-end solutions like fiberglass soundproofing blankets. They come in a range of materials, from the most popular — foam — to solid wood. They reduce the amplitude of the sound waves that pass through them, effectively soundproofing your door. You can nail them to the door, or to avoid damaging the door, you can use adhesive strips.
How to Soundproof a Metal Door
Metal doors present a logistical challenge because it’s harder to drill through them. To soundproof a metal door, try these tips.
- Add door thresholds: Door thresholds consist of neoprene with rubber protrusions that help fill in gaps at the bottom of the closed door. Unlike door sweeps, they attach to the floor of the doorway rather than to the bottom of the door. If you have a carpeted floor, having a threshold at the bottom of the doorway is crucial, because even the best door sweep will not perfectly seal the door with carpet. Some thresholds are flat, whereas others extend upward to form a double seal with a door sweep for a closed door.
- Use a soundproof blanket: Though they can be costly, soundproof blankets, which are typically fiberglass, absorb sound very well and are easy to install. Put some suction hooks on the back of your door and hang the soundproof blanket on them. If you’re not necessarily looking for a permanent solution, soundproof blankets also work well because you can hang them when you need them and take them down when you don’t.
- Use acoustic or mass-loaded vinyl panels: Vinyl is easy to use and install. You can buy a sheet of vinyl and cut it to the size of your door. To attach it, use adhesive strips. Mass-loaded vinyl panels don’t always enhance the aesthetic appeal of your door, but they are helpful in situations where utility is key.
