| If the building acoustics regulations in China don't work as expected (they don't work on most of the places so I presume they won't work in China as well, and maybe they don't even have legislation regarding building acoustics, don't know) then you have a problem.
It does not matter if the building is entirely made concrete and looks like is going to soundproof. It won't, most probably ! You are not a problem, the problem is the noise coming out from your neighbors, from footsteps above and from outside noise, ruining your recordings. This can be solved by doing a construction inside that space using lightweight materials (gypsum and mdf with bituminous materials or something like Green Glue). Enough for what you want to do. So you should, like stated by another user, build a room in a room but don't create a second floor, just improve the one you have now. |
