Studio Acoustic

As it is rightly said, Silence is Golden, so commercial acoustic studio are build because they must allow absolutely no sound to enter from a usually noisy environment i.e. recording booth. Double and triple walls, isolated concrete slabs, custom steel / wooden doors are constructed for soundproofing of recording booth. Given a reasonably quiet, solidly built house to start with, a decent acoustic studio can be created with modest expense and effort.
Acoustic Treatment
There are four primary needs of acoustic treatment:
- To prevent standing waves and acoustic interference from affecting the frequency response of recording studios, listening rooms, Auditoriums, Movie theatres etc.
- To reduce modal ringing in small rooms and lower the reverb time in larger studios, churches, and auditoriums.
- To absorb or diffuse sound in the room to avoid ringing and flutter echoes, and improve stereo imaging.
- To keep sound from leaking into or out of a room. That is, to prevent your music from disturbing the neighbors, and to keep the sound of passing trucks from getting into your microphones.
Acoustic Theory
The planning and construction of acoustic spaces for recording studio and other broadcasting facilities (control rooms, recording rooms, post-production screening facilities, etc.) is a very complex and delicate matter. It is relatively simple to plan the acoustic behavior of a large concert hall or theatre, as the laws governing sound transmission and diffusion on such a scale are relatively straightforward and well predictable on the other hand, the acoustic behavior of small rooms is very hard to predict and depend on a lot of different factors.
When planning and building studio rooms you are mostly dealing with two categories of problems:
- Sound proofing (this means, simply put, to keep inside sound in, and outside sound out).
- The optimization of the inner acoustics (frequency response, reverb time) which will ultimately affect the “sound” of the rooms.
