I had a complete re-do of a 1st floor bathroom. The bathtub was removed completely and replaced with a shower. The tile/plumber contractor created a new drain pan and wrapped it in rubber sheeting, up to the wall board, and then made a cut out for the drain, then poured concrete and made a p-trap of pvc below. Ever since I have noticed small flies like beer flies around the drain. I have flooded the drain with bleach, but the flies return on the walls and on the shower curtain. Anybody know what's causing them???
Try attaching cardboard egg-trays to foam rubber sheeting and covering your walls/ceilings with that (you'll need a lot of egg trays and foam rubber) - the idea is that the irregular shapes of the egg trays will disperse the sound and the foam rubber will help to absorb it instead of transmitting it through the walls. May also help with the sound quality of your recordings too (less echo).
Yea, I would say it would blow up but I don't know how big the explosion would be.
