Hi all,
I acquired this document on sound proofing. If interested, it’s a good (yet long) read.

The “Resilient Channel” is the stuff I was talking about. I just couldn’t remember what it was called in the business. This is the method that I have used before, along with staggered studs, it worked quite well.
I have never heard of QuietRock before, but it sound like it is well worth looking into. Also, with it being fire rated, it should make the building owners happy.
An other option is a product called Green Glue http://www.greengluecompany.com/.
Might be an other option.
