We don't have the opportunity or space to give everyone their own dedicated office, and cubicles I'm sure would be a living hell. I've looking into draping fabric from the ceiling, but you'd be surprised how challenging the logistics of setting something like that is (there are very few products in the market to support fabric like this, and we can't drape them from the drop ceiling due to weight). I've looked into free standing walls, but they tend not to have the sound absorption that is typically desired.
I'd like, for once, to read an article about practical solutions to this problem rather than just another person complaining about open office spaces thinking they've stumbled upon some undiscovered idea.
