What you should know about soundproofing a music studio
Some soundproofing may or may not work as you would like them to. The main idea of soundproofing is the space, mass, isolation, absorption, and dampening. The space is easy to understand the farther away the sound is the less noticeable the sound will be. Most solid mass objects will work to block sound by stopping the path of sound waves. When a sound wave hits a solid mass it bounces off and essentially “dies” out, leaving the other side of the object much quieter. Isolation creates breaks in path that the sound is traveling. Isolation is key to stopping structural sound and heavy vibrations. Absorption materials absorb sound like a sponge. Porous foams and cotton-based materials are common sound absorbers. They work by trapping sound and minimizing sound reflection. Dampening materials simply dissipate sound. All of these materials are visco-elastic in nature and disperse sound energy by reducing resonance.
Soundproofing utilizes multiple methods of sound control. The materials are used to stop transfer in or out of a space and are usually implemented during construction or later as a renovation. Mass and Isolation are the most common soundproofing methods used. These materials utilize the walls, ceilings, and floors. Sound Absorbing materials are used to treat the space acoustically after assembling is complete. Porous foam, cotton, or fiberglass panels are then mounted on the wall and ceiling to minimize sound waves and create a acoustically sound environment.
Porous sound absorbers do not block sound waves, they only minimize noise by de-energizing sound as they encounter each other. This sound absorber reduces sound in a studio, and also decreases echoes, reverberation and stops noise reflected off curved surfaces.
