Screws and nails for hanging stuff...

I am starting to plan a new studio construction and I was wondering: Is it possible to nail or screw some shelves on the inner leaf of an isolated wall? Will the holes created by the screws reduce sound isolation? Thanks

Hi tenkas - No it shouldn't be a problem if you get it right the first time ;) - if you make a series of holes trying to find the stud you will have to caulk them. cheers john
