Sound is a kind of energy that's produced when things vibrate and the energy has to go somewhere, so it travels outward, away from the sound source, making objects and the air all around us vibrate in sympathy until what's left of the energy reaches our ears. Inside our ears, the air vibrates too, banging on our ear drums and registering the sounds in our brains. In short, sound starts life at a source, travels through one or more media, enters our ears and lights up our brains and if you want to stop it in its tracks, you have to interrupt that chain of events somewhere along the route. The three easiest ways to stop sound are to turn off the source, increase your distance from it, or stop the sound waves from entering your ears by covering your ears or wearing earplugs at the rock concert. If you're living near an airport, the airplanes aren't going to stop flying just for you. Earplugs which are widely available from drug stores or online for just a few dollars and noise-canceling headphones are probably the most effective option if your objective is quiet work or study or traveling in peace on an airplane or train but they're not always suitable ways of reducing sound at home. If you're a musician and you want to keep traffic noise out of your room while you record an LP, you need to block incoming sounds in more drastic ways. Soundproofing materials can be applied to a wall that’s under construction or be added to an existing wall, post-construction. There are several ways to soundproof a wall. Improvements in the soundproofing industry have resulted in products that are more effective and cost less than traditional wall soundproofing methods.
Soundproofing walls are able to subdue unwelcome indirect sound waves, for example: resonance which generates reverberation, and reflections which cause echoes. Furthermore, all the soundproofing materials and wall soundproofing insulation have the capacity to lower the unwanted transmission of direct sound waves from where they originate to a non-voluntary listener via the application of intervening and distant objects within the path of the sound. There are various types of soundproofing walls on the market, and in order to ensure you have fully soundproof walls, you need to have the latest cutting-edge soundproofing panels, and first-class insulation for walls. Soundproofing walls is a serious business, and that is why you need the very best, as well as a professional installer. By choosing the top wall soundproofing materials, you can guarantee that you will get the effect you are striving for in your home or business. Soundproofing products often come with a Sound Transmission Class (STC) rating. STC is a measure of how many decibels of sound reduction a product provides. The higher the STC rating, the better. An improvement of 10 STC makes the noise seem like it’s been cut in half. On the other hand, a rating difference of 3 STC or less is nearly imperceptible and worth knowing when comparing products.
