2 Questions: Open space / fireplace (ETHAN?!)

[Mo-Kay]

I originally wanted to send Ethan Winer an e-mail through here, but I noticed that didn't fly


Anyway I don't care who comes up with an anwser, I just hope SOMEBODY can help me


Ok so here's the deal. As some of you might have read, I have 2 rooms, and 1 doesn't have a door. This means all that seperates my bedroom and studioroom in that place, is air.

-Now, my 1st question is: without a door... as what does the bedroom act like? A basstrap? A broadband trap? What?!

2nd question: I have a fireplace that isn't being used. The hollow part is about 2,5 feet wide, 1,5 feet high, and 2 feet deep.

-My idea is to stuff the damn thing with rockwool or something like that, put some cloth in front of it, and use it as a bass trap. Will this work?





Any (helpful ) anwsers would be highly appreciated
Thanks

I think the bedroom will act as a mega bass trap if you fill the door gap with material-covered rockwool/703/rigid fiberglass when not in use. But that's just my theory. Hope you get an answer from someone more educated/experienced than me on the subject

IF you leave the fireplace open, it will act like a resonant chamber at around 200-300 hZ, and "color" the room sound (by adding extra resonances at those frequencies) so filling it with rockwool is a good plan.

If you were to place thick rockwool (like 6" or more) in place of your non-existent "door" between rooms, then you should indeed get a giant bass trap effect; with a 12 foot deep room behind the rockwool, it would peak in absorption at around 23 hZ; but it would also absorb below that, and pretty much everything ABOVE that as well. IOW, it would act about the same as having a large, open window there that everything can pass through, never to be heard again. (this would not be a bad thing)

NOT putting rockwool across the door would likely give you a false bass boost in the control room, probably causing you to make bass-shy mixes... Steve

BTW, if this doorway were in a CORNER of your control room, it would be even MORE effective since all modes peak in corners.
