[QUOTE="Brad Weber, post: 82688, member: 114"] Re: Acoustic Experts - I need you! Before you get too far you might also want to consider that (hopefully) the room won't be empty in actual use. Some people in the space may provide a good amount of absorption and diffusion while ambient noise may also help mask lower level acoustical issues. Unless you model the room with and without and audience then guesstimating the effect of an audience is still somewhat an art. For a black finish like that something like [url=http://www.owenscorning.com/around/sound/commercial_acoustics/black-acouboard.asp]Commercial Acoustic Systems: SelectSound® Black Acoustic Board[/url] can be very effective, the 2" thickness has pretty good absorption values throughout the frequency range you noted and it typically meets flame spread and smoke developed requirements (although that should be verified for the specific project requirements). There is probably something similar available there if that specific product is not available. [/QUOTE]
