DIY Soundproofing
If the noise is coming from outside of your home, consider upgrading your windows and doors to help. Installing double-pane windows or a solid-core door can help reduce the amount of outside noise coming inside. Sometimes simple solutions can help, such as searching for gaps and filling them with caulk, or packing acoustic foam around the window frame. Small gaps can allow in a lot of noise. And by filling them, not only do you lower the noise level, but you increase energy efficiency.You can take it a step further by hanging heavy curtains on your outside-facing windows. This is a quick but effective way to stop a little extra noise from entering your home. It also tends to help with energy efficiency, too.
Internal noise requires solutions between rooms. If you can hear everything that happens in the next room, soundproofing your walls and ceilings with acoustic tiles can make a difference. There are also ways to use decor to help dampen the sound, like lining your walls with bookshelves.
Soundproofing your floors is another good option, especially if you live in a multi-level home. You can add rugs or carpeting to reduce the noise from walking around in your home.
Get Pro Help
DIY soundproofing can be effective and solve some of the basic problems, but I always recommend calling in a pro for the best results. A pro can help identify the source of the problem and offer more thorough solutions, like adding soundproof drywall or extra insulation.You can soundproof individual rooms if you like. Home offices, entertainment rooms and bedrooms are some of the most common choices. Soundproofing an individual room costs $10 to $30 per square foot on average.
Professionals can use a variety of techniques to prevent sound from getting in or out of a room. An additional layer of drywall can reduce noise, and some drywall manufacturers offer material with a soundproofing core. Extra insulation can block sounds as well (and indeed, this often helps with energy efficiency too). A pro might also attach acoustic panels or thin but dense rolls of mass loaded vinyl against existing walls to muffle sounds. They can also install a noiseproofing compound between two layers of drywall.
