Have you ever wondered how sound works. Well in this paper I will include what sound is, how it works, how it is measured, give examples, and even tell you about the structure of soundproof walls, floors, and doors. To begin with, sound is reflected off surfaces every 0.01 second. Sound is produced through waves. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal. Sound waves need to travel through a medium such as a solid, liquid, or gas. Sound is the energy things produce when they vibrate (move back and forth quickly). It is measured in decibels or dBA of sound pressure. If you bang a drum, you make the tight skin vibrate at very high speed (it’s so fast that you can’t usually see it), forcing the air all around it to vibrate as well. As the air moves, it carries energy out from the drum in all directions. Eventually, even the air inside your ears starts vibrating—and that’s when you begin to perceive the vibrating drum as a sound. In short, there are two different aspects to sound: there’s a physical process that produces sound energy to start with and sends it shooting through the air, and there’s a separate psychological process that happens inside our ears and brains, which convert the incoming sound energy into sensations we interpret as noises, speech, and music.Soundproofing Soundproof material is amazing to me. It allows you to not be able to hear your neighbors if you’re in your apartment. Blowing insulation into the interior spaces of existing walls can make the walls more soundproof, reducing the amount of noise coming into a room. If your neighbors next door loves to party and all you hear is noise then getting soundproof walls, floors, doors, and ceilings will be a helpful towards you. The material to use to soundproof a room the best is Roxul AFB. It’s made of a winning combination of soundproofing rockwool and thermal insulation. It’s low cost and wide availability make it a great choice for your remodeling project. It’s soft and flexible, making it easy to tightly stuff the batts into standard stud wall cavities. Conclusion Now that i’ve explained what is sound and soundproofing is, you should have a better understanding.
