Ways to Reduce Noise Pollution at Home..

I work from home, and apparently I am in good, and growing, company. There are 3.1 million of us in the United States who now work from home, and this number is increasing. Do you know what we do for at least a part of our day? Get distracted by a noise: Music blaring, a bus passing or a neighbour’s conversation about what’s for dinner. 

These sounds seep into a room through those pathways known as windows and doors, as well as floors, walls and ceilings. To decrease sound you must obstruct or dampen the sound wave. There are two main ways to create more quiet at home: 1. Adding surfaces that absorb the sound, or reverberation, before it gets to your ears, and 2. Blocking it entirely.

Sound absorbers for the home

Blocking sound and absorbing sound are two different things, says Matthew Boughan of Acoustical Solutions in Richmond, Virginia. Absorbing it is easier. Some ideas to try:

Add 1-inch-thick acoustic panels 

Sheetrock, a terrible absorber of sound, can be the culprit of that tinnyness you hear when talking on the phone. To remedy this, cover your walls with materials that have a noise reduction rating (called NRC, or noise reduction coefficient) of 0.85 or above, Boughan says. He recommends a 1-inch-thick fabric-wrapped acoustical wall panel.

Acoustic panels come in a range of colours and fabric styles and can be designed into your interior decor. Installation is slightly more involved than hanging a picture, Boughan says. 

You want to spread out the absorption evenly among all walls and even place panels on the ceiling. Panels can even be turned into a gallery wall.

Concrete flooring

If your floors are concrete or cork (shown here), congratulations. Those are among the best materials for sound absorption. 

Carpets, rugs and padding 
If your floors are sporting hardwood, tiles or linoleum on subfloor concrete, you may want to try rugs or carpet coupled with a sound-absorbing padding.

Floating hardwood

There are other options for flooring, such as floating hardwood, Morrall says. This type of flooring installation includes a gap between the subfloor and your actual floors, which effectively dampens sound.

Draperies

 

Draperies can be both sound absorbing and sound blocking. For sound absorption, look for heavy materials such as velvets and wools. And if there’s a mass-loaded vinyl layer, even better.

A recent breakthrough in sound-absorbing draperies came from EMPA, a lab in Switzerland, and Swiss textile designer Annette Douglas. They are gauzy, allowing in some natural light, but made of a modified polyester designed to absorb sound. They come in three different designs (Carmen, Formoza and Marmara).

 

 

Now for the more difficult problem of sound blocking

“If sound is pouring through the window, it means the frame is substandard, the panes of glass are not airtight, or there are not enough panes of glass there,” Boughan says. “You need to replace it or cover it.”

Caulking
A lot of outside noise can seep in through windows. A mere 1 percent gap in the sound barrier transmits 50 percent of sound – that’s the rule of acoustics, Boughan explains. Try something simple like caulking around your windows, sealing any gaps.

Window seals 
More radical solutions are acoustical seals. A seal is a track that makes it possible to add another layer of airtight glass in front of your existing window. Once it’s installed, your window won’t open anymore. 

Acoustical blankets
Acoustical blankets look like those mover’s blankets in freight elevators. 

Triple-pane windows
A prettier solution that still involves fresh air and light: You can replace double-pane, or double-glazed, windows with triple pane, says Morrall. Installing triple-glazed windows requires the expertise of a contractor, and they typically cost 10 percent more than double-pane windows.

If you are in an office with pocket doors, think about moving your office to another room. They create a wall cavity that can’t be insulated, Morrall says. And there are no jambs to close the doors against.
