acoustic testing of irregular live room

Hello,

I'm working on my relatively small live room. 11x16x8

While I've kept the floor live, I pretty much intend to make the rest very dead. I'd like to keep the reverb time more or less even on all frequencies.

My thoughts tell me that I will need severe bass trapping in such a room, but I'm not sure exactly which method to go with.

The room would be a conventional triangle, but I was forced to install my heater in one corner of the room. I've built a closet around it which takes up 2'x3' in one corner. Now the room is certainly not symetrical, but I don't know if this is important for drums and guitars.

How do I test a room to find the problem frequencies to fix?

I have a Behringer test mic and ETF software. Do I toss studio monitors into the room? Where would I place them? This is a much different situation as placement will very quite a bit.

The room is 16x11x8. It has a drop ceiling which I will be putting a layer of 4lb 4" Rockwool above. As stated before one corner has a 2'x3' section taken for the furnace closet.

I've got a ton of rockwool, but I just need to figure how to test the room so that I can actually find the problem areas and treat it.

Thanks
Brandon Drury

Looks like no takers on this one - did you really mean "triangle"?

Is the 8' ceiling to the drop ceiling, or to a solid barrier, and what's the drop ceiling material?

Just off the top, having 8' and 16' dimensions will give you problems @ 70, 140, 210, etc - hopefully that ceiling is absorptive so the hard boundary above it will dominate the modes... Steve
