| The fact that the frame is metal makes this a very bad concept and effectivly ruins your time and effort put into a stager stud wall. Metal, because it is so dense will transmit more frequencies faster and easier than wood. Having a coupled metal frame between the 2 walls will be like having an open 1 1/2" PVC pipe between the 2 rooms.
Having to change it latter will suck. Check out "The Master Handbook of Acoustics" most of it is black magic and totally over my head, but there are diagrams and cut-aways of walls that will be very helpful. Also "How to Build a Small Budget Recording Studio"
Good luck. |
