Actually Folk freak we got that sound leakage down heroically using layers of inexpensive materials done in a constrained layer damping system over the regular sheet rock, if we would have been able to build the wall out more we could have knocked it down very much more.

There is a huge difference between designing from scratch and retrofitting. Also the DIY Network is really cheap so our solution had to be as inexpensive as possible. 

We used cemment board, sheet rock, cemment board sandwich with green glue between all layers then we used a custom made absorbing diffusing panle the room sounded and looked great.
