My cousin owns a recording studio where I live that is the size of a barn (it's a converted barn). He's in the process of upgrading his digital recording with thousands of $ of gear, Mac computer, interfaces, etc.
He also plans on building a recording booth inside the studio, where the engineer can sit. After he described the booth, I told him I wanted one in my practice room for trumpet .... playing inside one of these booths would render your practice unhearable outside the booth, generally speaking. You could practice 24/7. With impunity. You could laugh at your sleeping neighbors.
So ...... the bad news is that, according to Richard, those sound proofing materials are EXPENSIVE. No, egg cartons and any number of other home sound proofing remedies will not work, so he says. The carpentry work is easy and not expensive but the actual heavy and dense foam material makes his expected expense for this booth--where he can be isolated from the recording, which he hasn't had before--is several thousand dollars. If he tried to find one that was pre-built, especially for recording studios, it would cost more.
Any thoughts anyone on how to make one of these "sound isolation booths" with cheaper materials that would also work??? Let's just say, for argument's sake, that there has to be one window, so it doesn't feel like a "sensory deprivation tank."
I encountered this when I was a drummer in college. I'm just leading a loud life, I guess. I moved several times, at the request of my neighbors/landlords, until I found the ideal place. A garage that had been soundproofed by the former owners, for their rock and roll band. I rented the garage, and could play full tilt in there anytime day or night ..... outside, standing next to the door, you could barely tell somebody was inside, playing. Honestly, I wish now that I had looked into seeing how it was done and with what materials.
Any help would be greatly appreciated. I want a booth.
