Hello
First I know a lot of people have asked same question but Im starting from scratch and have a few twists....
I want to build a 16' X 30' shed in my backyard for a practice room for my drums and my band. I plan on building it without windows. I plan on using concrete block to build the walls. The floor will be concrete. I may even pour the ceiling at 10' from concrete also (I used to be a concrete contractor)
I am also looking into GREEN GLUE

Maybe I can build a framed shed and rock the inside with this method of sandwich construction. Is GREEN GLUE better than MLV ?? It sounds to me IF green Glue works it is better

I am open for suggestions, advice and help from those who know what they are doing .... =)
Does anyone know how much sound a solid block room would alow to escape in layman terms ? I dont want my neigbor to hear a thing above a voice level from 50-60 feet away....and I play LOUD LOUD ....
I should also add I want to do whatever I can inside the room to make it sound good for recording reasons....
Now the issue ove air in and out and cooling....... gee,//////
Thanks guys....
