![]() However, don’t rely on carpet as a foolproof method for reducing echo and reverberation. This is because the structure of a carpet’s fibers will absorb and muffle sound waves reverberating around the room. Simply put, it adds a soft layer between the noise source and the floor, meaning the impact is cushioned as it happens.Ĭarpet will help with airborne sounds to an extent, too. 1) Carpet or RugsĬarpet is a pretty decent option for reducing impact noise before it enters the building’s structure. If you can’t rip up the existing floor (for example, if you live in an apartment), here are some solutions for reducing noise transmission. This is the difference between limp and rigid mass.Ĥ Ways of Soundproofing Existing Floors (in Apartments)Īs you can imagine, your options to make a soundproof apartment floor (that’s already built) are slightly more limited. Now imagine throwing the same ball at a brick wall it’ll bounce right back at you. On impact, the ball will drop to the floor. Imagine throwing a ball at a bed sheet hanging on a washing line. It’s especially effective against low frequency sounds. As such, a sound wave can’t ripple through the material as easily because a big part of its energy is dissipated by deformation. On the other hand, limp mass has much higher deformation. Some noise will bounce back and some noise frequencies will go through (mostly low frequencies). Rigid mass would be something like drywall or bricks. It does get a bit more technical than that, as we can look at limp and rigid mass. ![]() It works better against middle to high frequencies. ![]() However, mass is not equally effective across all the sound frequencies. ![]() Simply put, adding mass to a structure makes it more difficult to vibrate, and for sound to push through. Mass is one of the easiest principles to understand. ![]()
