Water for soundproofing. Ideas and thoughts.

Just saw the note on sand on pg1, and wanted to mention that my buddy and I built some wicked speaker cabinets, which were a box in a box, with a 1" layer of sand in between. They were phenomenally good, no box noise, no vibrations even. But at 500# a piece they needed to stay where they were put! LOL

I believe you can also get a large-scale acoustic canceller, similar to the noise reducing headphones. Play it loud enough and it will cancel out any noise in your room. Might be expensive, but there aint much about indoor growing that isn't!

Drywall is so much easier than everything being discussed here... Simple, cheap and it works if you use it correctly

Can you really get these? I would think the complexity of the environment would make them infeasible. With headphones there is a sharp demarcation from one side of the headphone to the other that can be modeled to determine algorithms that predict the sound on the inside of the headphone based on the sound outside the headphone. To my understanding, its this acoustical separation and the relatively simple acoustic environment between the headphone and the ear canal that allows noise canceling headphones to be effective/feasible. In an open room, the interplay of sound waves in the face of unknown shapes, surfaces, reflections, absorptions, etc. make it too complex to generate a canceling sound that works.

isn't it somewhat fire retardant too? Win-win.

5/8" drywall is almost always Type-X, meaning it is fire resistant. A single sheet weights like 70 lbs so is great for weight. Also $8 a sheet!

yep rrog is right drywall and greenglue it works...

 

[rrog]

Bud, I was really close to getting greenglue. You tried it, then?

That's damped drywall. Same as adding greenglue and drywall or quietrock
