Follow this three-step process: Reduce noise transmission from the outside, reduce noise in your home, and utilize sound-absorbing materials to mitigate the consequences of any noise you do make. To improve the peace and quiet in your house, try these simple soundproofing techniques.
Decorate with Curtains and Rugs
Heavy drapes are great at stopping noise transmission from the outside. Upholstered furniture, area rugs, and wall-hung quilts are viable options too. Carpets, cork flooring, and acoustical ceilings also help with sound absorption in large open areas.
Add Insulation and Drywall
Insulation is essential in turning down the volume of daily living, and a layer or two of drywall will substantially reduce sound transmission.
Try Sound-Dampening Underlays
Sound-dampening underlays can limit noise transmission from the floor. The dense sheets are rolled over the entire floor, underneath the top layer of flooring, and taped along the seams. There are sound-dampening underlays for just about every floor type, so be sure to choose the correct one.
Weatherstrip Windows
Windows and doors tend to be the weakest link in your sound defense. Weatherstrip all points where sashes meet jambs, headers, and sills. In addition, fill any tiny gaps around moldings with an acoustical caulk sealant.
Install Solid-Core Doors
Solid-core doors offer better insulation from sound than hollow-core doors. A well-fit solid door will significantly reduce sound transmission, but it will not completely wipe it out. To complete the job, seal all the gaps around the door at jambs, header, and sill.
Apply Duct Wrap
Plumbing can cause a considerable amount of noise in your home. While the sound of water running through pipes is unavoidable, you can cut the noise in half with just a little insulation. Similarly, duct wrap will tone down the whoosh of air rushing through ducts.
Adopt a Shoes-Off Policy
There’s nothing more irritating than the sound of hard-soled shoes clacking against hardwood floors in the middle of the night. Remove your shoes at the front door and keep a supply of slippers by the entryway for friends and family.
Opt for a Quiet Dishwasher
Before buying appliances and outdoor power equipment, check out the sound rating—measured in decibels, or dB for short. A quiet dishwasher might have a rating of 45 dB, while a dishwasher with a dB rating of 55 would be about twice as loud.
Use Sound Reduction Pads
Put rubber pads under countertop appliances to add a cushioning layer between the motor-driven machine and the hard surface, cutting down on noise. The same can be done for other household appliances, from air-conditioning units to washing machines. There are many options, including rubber, neoprene, and cork sound-reduction pads.
Fix Squeaky Floors
Squeaky floors can be a noisy irritant. For a long-term solution, tighten up the floor to prevent floorboards and treads from rubbing against other boards and creaking. You could also try installing an isolated floor over the existing floor.
Switch to a DC-Powered Garage Door Opener
Automatic garage doors can generate a staggering amount of noise. Direct-drive openers with a direct-current motor have fewer moving parts, and the DC technology allows soft starts and stops, all of which contribute to a quieter opening system.
