So, what if I effectively made a cylindrical wall of Rockwool panels? What if the 7 speakers of my 7.1 system were flush with that barrier? It's a small room & reverb is N/A. | need a considerable level of absorption to tame the room modes o This seemed like the path of least resistance.
Any thoughts? Was thinking about safe 'n'Sound
to isolate you need double walls (and floors and ceilings) on offset studs, limp membranes, etc.
a lot of what sounds funky inside a room (assuming you don't mean isolation) is well up in frequency and you can do a ton to clean it up with appropriate absorption of much less thickness appropriately placed. for example when you listen to aregular four string bass guitar, normally tuned, the fundamental frequency of the lowest note (at about 30 Hz) is at least 12 dB below the second harmonic at 80 Hz (usually- this is how it comes off the pickup straight into the mixing board, - a classic bass amp like the Ampeg SVT and 8-10 inch speaker cab will have its own fairly severe roll off below about 50 Hz) . Controlling the much louder 2H at 80 Hz (and higher harmonics) can go a long way to cleaning up bass messes, but in the end, the way to get reasonably flat bass across space in home sized rooms is really multiple subs so that you energize multiple different room nodes and everything kind of more or less evens out. Or tens of feet of absorption covering eat least one entire wall. Your choice.
Well, much thanks,but.. hrm... Well, I wasn't approaching this from a soundproofing context. The room has some resonance issues & being a small room, well.. there just isn't much space to flatten out the problematic bass frequencies.
I'm going to construct a number of panels using rockwool, so I'll obviously be able to experiment (I also have a measurement mic).
From a recording standpoint, sitting in the center of a cylinder of rockwool would probably be a pretty good idea, but what about listening in a very small room?
Something like one of those foam microphone isolation filters... Except I'd be the microphone...
I had the thought, but further information on the matter eludes me.
If you could shove a pair of subs at appropriate locations that would probably help with modes, as would getting the listening position a bit away from walls and yet not in the center of the room.
