Adding extra sound insulation to your home does not necessarily need a huge amount of work. Depending on your situation, a series of small adjustments, easy to do on a weekend, you can make a big difference. But for those owners who wish to transfer audio between home and the external environment, a series of repairs to mitigate further more intensive work can be done. The good news is that in both cases, many of the techniques that professionals use on accessible products and materials.
The empty sky can be considered the best medium for sound to travel through, so that ultimately the best method of first reducing sound transmission by reducing the airflow in your home. This happens just as you would in weatherization projects, but with the extra steps to block or absorb vibration. You might be surprised to discover that even a thick brick wall would be a poor sound barrier, with a few holes drilled in the mortar. Understanding this gives you a great advantage in your project, such as reducing and restricting the air flow is one of the easiest you can make arrangements. Think of this project the same way you would in their efforts to combat the cold, for example, visible spaces under doors and windows and add weather stripping to seal leaks with caulk. This simple step goes a long way to the airflow and superior sound quality to stop transmission.
The first, an indicator of many enhancements that can make that will begin by reviewing what is known as the Sound Transmission Class of STC of different sound combinations lock. Therefore, the higher the STC rating is soundproof. The typical 2×4 wood wall framing, covered with 1 / 2 “drywall gives a score of 35, for example. As a general rule, I think for every 10 points of STC, they will have a 50% reduction in sound. To a very soundproof, must point to an STC of 50 using a variety of techniques in combination.
Achieving a Grade 50 STC can be done with a standard 2×4 wall covered with 5 / 8 “drywall on both sides, with a board of mediation and are completely soundproof insulation. This is a lot of layers and lots of protection for sound attenuation. But This is not your only option for achieving high STC ratings. Another option is to install steel resilient channels running perpendicular to the wall studs, creating a small air gap between the stud and drywall and prevent noise problems travel through the material to another. This technique is based on the principle that sound travels easily from one object to another, and by adding a gap between the audio materials that tend to die rather than byproblems.
