Room acoustics
The very best reference book and how to that I know of is: Master Handbook of Acoustics. by F. Alton Everest, and Ken Pohlmann. As an audio cheapskate, I save $20 and checked it out from my local library. |
I have an open floor plan so this will not work for me, but if you have an enclosed listening room you can use an online calculator to get the room modes (freq.s where the sound amplitude "stacks up" i.e. wave superposition). http://www.mh-audio.nl/sg.asp |
I've actually just started using REW and was pleasantly surprised at the measurements. I do need to tame my frequencies below 200Hz, but there don't seem to be any consistent peaks now that I've brought my orange tree in the room for the winter. The very large pot of moist soil seems to have done a beautiful job as a bass absorber. Before that, I had a few peaks that wouldn't decay.. My question is this: how do I know where to put bass traps when I make them? My guess is to generate bass tones at the problem frequencies, then walk around with an SPL meter looking for areas with the highest measurements. I'd love other ideas.. |
