In Reply to: How do you measure room acoustics? GM ? posted by Bruce on January 2, 2000 at 13:25:16:
The RS SPL meter can still be inaccurate even with a correction curve. I have read in a few places that meter-to-meter consistency is not good, but I haven't run measurements on multiple units and so can't agree or disagree.
There are multiple PC programs that will function as a RTA, but the computer environment is rather noisy (fans, circuits close to the sound card, etc) so they can also be interpreted as relatively inaccurate. What DOES do the trick is a real stand-alone RTA. These units however can be a little expensive depending on your budget (I've seen prices in the $300 range for basic models from a variety of manufacturers). I've found that some places will rent the units, so that may be a good place to start. Call your local dealer and see if they will accomodate. If not, they may be able to point you in the right direction.
Doesn't sound like you really need a program that will MODEL your room modes/acoustics as much as you simply need a RTA of your room acoustics. I'd start with your ear and your RS SPL meter to get a general idea of what is going on. See what you can do to make the peaks/valleys smoother by playing with speaker placement in particular, but also furnishing placements.
Hope this helped. Feel free to ask more questions if you wish--I don't mind!
Happy listening!
