3️⃣ The three basics of sound control are stiffness, mass, and balance. Does your wall insulation help with the sound control in your home?
🔊 To first understand sound control, we first have to understand that sound, at a basic level, is energy. This energy is experienced through vibrations, called sound waves, that travel through the air or travel through another medium (solid or liquid). These vibrations can be heard when they reach our ears, as our brain processes the reception of these energy waves, thus giving us "sound."
🔇 Sound absorption is the process where energy from a sound wave is reduced as it passes through a medium. Having a sound-absorbing insulation is great for not only keeping exterior noise out, but also keeping interior noise at bay.
🏋️♂️ When we think about the term "mass," we're talking about density and all the matter and substance that makes up an object. In relation to sound, the thinner and lighter something is, the easier it is for energy to pass through. This means a material with less density isn't able to control sound as well as a material with thicker density. When it comes to insulation, fiberglass and open-cell foam only have a 0.5 pound density. Closed-cell foam performs better with a 2 pound density. But Nu-Wool performs the best with a 3.5 pound density!
☁️ Then we have "stiffness," also known as rigidity. The more rigid something is, the easier it is for sound to pass through it and even bounce off of it because there is no natural absorption. Insulation like foam is very rigid when applied and so it does a bad job of absorbing sound. Fiberglass is a little better with some absorbing properties. But again, Nu-Wool is best as it is the most sound-absorbent and flexible insulation on the market! Given its soft rigidity and its flexibility, it performs excellently at absorbing sound.
🏡 To create a balanced, sound-controlled environment, you need an insulation that's going to get the job done. With a high density and yet a flexible, absorbent makeup, Nu-Wool Premium Cellulose Insulation is the best insulation to create a noticeably quieter home!
