Soundproof Drywall

What is soundproof drywall?
Soundproof drywall is a type of drywall engineered to block the travel of sound between one room and another. Soundproof drywall is similar the regular drywall that is used in construction around the world; the only difference is that soundproof drywall contains additional layers that are designed to absorb sound. Soundproof drywall can be used in the construction of walls, ceilings, or floors.

How does soundproof drywall work?
The purpose of soundproof drywall is to block sound waves from traveling through the soundproofed wall, ceiling, or floor, by absorbing the sound waves, or “noise,” a process referred to as “noise absorption.” The process of noise absorption is also called “damping,” and damping is accomplished by adding density and layers to structure conducting the sound, thereby adding disconnection points between one side of the structure and the other. Subsequently, these disconnection points serve to impede the path of the sound wave, thus preventing the sound from becoming airborne and audible on the other side of the soundproofed structure, whether it is a wall, ceiling, or floor.

In what scenarios can soundproof drywall be used?
Soundproof drywall can be used in various types of structures, such as professional and home recording studios, multi-family residential structures, conference rooms, or any other place where noise reduction is necessary. For example, soundproof drywall is often used in the construction of recording studios where music is played, mixed, and recorded, to prevent the sound from escaping from the recording studio and disturbing the surrounding businesses and residences. Similarly, soundproof drywall is also a component in the construction of vocal recording booths within recording studios. However, in this case, the purpose of the soundproof drywall is not only to prevent the sound from traveling out, but more so to prevent extraneous sound from traveling into the booth. This ensures that the final professional recording does not include any street noises or random sounds emanating from other parts of the building.
