It feels great to be loud sometimes. Sometimes fun involves making some noise. Luckily, there are lots of soundproofing techniques that can help you achieve this. Keeping sound contained is part of good architectural design. It is also a good architectural improvement for any noisy area. In this article you will find techniques that will allow you to keep sound in, or out, whichever you are trying to achieve.
The ability of a material to block sound is measured by a rating called the Sound Transmission Coefficient (STC). It runs on a scale of 1 to 100. The ability of a material to absorb sound is measured by a Noise Reduction Coefficient (NRC).
There is a variety of ways to soundproof a room. From insulation to acoustical tiles that rest on the outside of the wall, there are many ways you can maximize the soundproofing capabilities of your space.
Too much noise can have a serious impact on mental health. According to this article from Families.com it can cause hypertension, stress, and high anxiety levels that can ultimately have a large impact on our well-being.
