WHAT IS SOUNDPROOFING?
Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barrier to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active antinose sound generators.
Soundproofing is adding mass and density to a structure to contain or block sound. In doors this could be as complex as an acoustic door, or as simple as adding an acoustic door seal kit. In walls it can be adding sound panels or building out walls with soundproof barriers like Audio Seal Sound Barrier or Green Glue. Whatever route you go, soundproofing involves adding a product that increases the mass and density of the wall, door, or other surface and covering that surface with your material 100%.
EXAMPLES OF SOUNDPROOFING
Examples of Soundproofing are:
Audioseal® Sound Barrier
Clearsonic Isolation Enclosures
ABBC-13 Sound Blankets
Barrier Wall Panels
Composite Foam Materials
