Acoustic soundproofing may become a tedious process if you don't really know how to fix the problem or where to begin. There are many different types of soundproofing insulation materials and products available to choose from. Some products will help completely eliminate the noise while others only help to reduce the amount of noise you hear. Here are some scenarios that might help you out when in search for the right materials and ways of reducing sound penetration in a room.
What does soundproofing a room mean versus acoustic treatment of a room? Acoustic treatment of a room has to do with improving the quality of sound within a room. This means that a sound that is recorded within an acoustically treated room will be the same sound you hear when that recording is played back. Soundproofing a room pertains to keeping the sound within a room from leaking out and keeping outside sounds from coming in. This is also known as sound isolation.
Will attaching materials like egg boxes or foam insulation panels help in the soundproofing of a room? Egg boxes might help the acoustics of a room because it will help break up sound reflections coming off the hard or flat surfaces of the room. On the other hand, egg boxes are not helpful in the soundproofing of a room. The same can be said about certain materials like foam, rockwool, and even lightweight ceiling tiles. These won't effectively soundproof a room they do however help in the acoustic treatment of a room by dampening out sound resonances within that room.
Where should one start looking when in search of places where sound is penetrating a room? Start with doors, windows, walls, ceiling, and floors because these are the main ways that sound can enter a room. Determine if any of these need sealed for gaps, cracks, or openings. Make sure your door is made of a solid material. Make sure your windows are double-paned. Next determine if you wish to add insulation within your existing walls. This can be done by inserting foam or spray insulation directly into the walls to make them denser. Use plush carpeting, upholstered furniture, and soundproof curtains to finish it off. Most soundproofing materials can be found at a regular builder's supply merchant or home store. If you are having trouble finding certain materials you can always do a search for that specific item online. Most manufacturers allow you to purchase materials directly from them at a discounted price.
