Hello,
I'm currently making plans for building something that remotely resembles a professional recording studio. My studio construction consultant came up with the idea of filling the studio walls with sand instead of mineral wool. His point was that this would be an inexpensive way to make the wall construction dense, and thus more soundproof. Of course, getting the sand in there is a bit more difficult than mineral wool. He also suggested we don't use gypsum walls since we could have a disaster if something crashed into the wall and broke it...
Not that I doubt his skills (he's been building studios for Swedish Radio for 25 years), but I still wanted some comments on this approach, since I've never heard of this construction idea from anybody but him (and I've been doing quite some reading). We have an idea for how to get the sand in there, and all the way up to the ceiling - but what do you think about the sound transmission loss compared to the good old gypsum walls filled with mineral wool?
Cheers
