Hadn't considered replacing the sewer pipes,... I'll check into the cost involved. I was thinking that it would also be logical to find out where the "noisiest" wall(s) are, and definitely double the sheet rock layers there,.. so looks like I was on the right track.
This basement also has a full bath, located almost in the center of the basement. I'm considering moving the entire bath to one side, and making it a half bath only, in that I don't really need a tub/shower in the studio.
The cost's may out weight the benefit though, especially since this will be a "part time" studio,... at least until I can retire from my full time gig, if ever with this economy!
