Acoustic Wall Build

Last month we went to work on a much needed aesthetic and acoustic upgrade in our control room. What was once just a couple of windows draped with curtain is now a completed acoustic wall covered with natural pine slats over 4-8" thick rock wool material. This gives the room a great balance of absorption and diffusion, meaning: some of the high frequencies remain-- instead of being fully soaked up, they are scattered almost randomly to avoid hard, reverberant reflections. Rooms dedicated to mixing as their main purpose benefit from a great deal of bass trapping and broadband absorption, but also need to maintain some 'liveness' to provide some semblance of a realistic environment for the mix engineer. 

The finished results were better than expected-- music emanating from our monitors feels bigger, more accurate, and more energetic.

There were some challenges along the way, as expected building anything into a 100 year old house-- the walls are anything but square.

Follow along below to check out the process:

We started by filling the windows with two 2" rockwool panels.

We then finished it off by placing a pine board on the top and bottom of the wall.
