Hi all!

I am trying to figure out the missing link in my knowledge about acoustics. I have read (and understood most of I tink) the works of Everest, Tool, Newell, KleinTischy and random articles a tGS and such, the excellent manual from REW etc. What I would like to read now is a compilation of how to interpret the results that REW gives me. In all of the works that I mention are of course help provided, but in small segments. I have tried to sum up the clues in a separate document, but a guide in how to interpret, and perhaps also rectify the different areas of problems would be of great help. Does anyone have or have seen something like this in a book or in an article on the net?

My own REW tutorial explains how to set the graph ranges to best see the items of interest:

Room Measuring Primer

Your question is fairly general, so it will help if you ask one or two specific questions at a time.

I'm someone who's studied some articles for about a 9 months part-time, treated and measured two separate rooms with moderate, but somewhat satisfactory, success. I can say you want the most even (+- 10dB between 32-16000Hz) frequency response, shortest decay time (waterfall graph, <500ms RT60) and widest Q (waterfall, freq response) possible at your listening position. More broadband, thicker, dense and FRK'd panels are better than less but it's better to err on the side of more, thinner, less-dense panels than fewer, thicker, more dense. In other words: treat the juice out of your room then measure it and evaluate given the criteria I've provided.

I can add that a live room should perhaps have a longer decay time than a control room but it depends on room size. Most of us are in small rooms therefore more treatment is better and you can always add ambience at mixing. If you have a smaller room but want more reflectiveness then add diffusion.
