Should I line all my studio and control room walls with fibreglass?
Well, not unless you want to provide a very dead environment with a weird frequency balance. If you made the room completely “fuzzy” by lining it all with absorption, you would effectively kill of the reflections, and high frequency ambience, but you don’t significantly affect the modal response in the room below 300-400Hz. This leaves the room sounding “wooly”, or “boomy”, lots of low rumbly voice and music, with no top end liveliness. It’s important to balance absorption with diffusion so that you have a room that sounds balanced and pleasant, without having distinct wall reflections that add coloration. You can buy commercially manufactured quadratic residue diffusers, or find the details of construction for your own use in the Howard Sams Publication;”The Handbook for Sound Engineers” by Glen Ballou. If you don’t own this book, you should, even though it seems like a lot of money; it has a lot of answers to questions on both rooms and electronics.
