Acoustic treatment focuses on controlling the sound within the studio, while soundproofing focuses on preventing sound from escaping or entering the studio.
Acoustic treatment is typically achieved through the use of absorbent materials, such as acoustic foam, fiberglass, and mineral wool, to reduce the amount of sound that is reflected off of hard surfaces and create a more balanced and natural sound. These materials can be strategically placed on the walls, ceiling, and floor of the studio to absorb unwanted frequencies and prevent echoes and reverberation.
Soundproofing, on the other hand, involves the use of materials and techniques to block or reduce the transmission of sound through walls, doors, windows, and other openings in the studio. This can be achieved through the use of soundproof panels, mass-loaded vinyl (MLV), and other materials that have high density and low sound transmission loss. Soundproofing is important for preventing sound from leaking out of the studio and disturbing others, as well as for preventing outside noise from interfering with recordings.
Acoustic treatment and soundproofing are both important considerations when designing and building a studio, and the specific techniques and materials used will depend on the specific needs of the studio and the type of recording that will be taking place.
