I've just finished the first phase of treating my room and I'm unsure of how to interpret the resulting waterfall graphs. The room is small (10x12x8), so I basically had to treat every single surface (4" 703 straddling the corners, 4" around the RFZ, 2" around the back. The result is a dead room that is great for mixing and mastering. Modal issues are still there, but nowhere near the magnitude they once were. I'm hoping to install some panel traps soon to target them.

Anyway, Fuzzmeasure defaults to -102 db as the baseline, but my signal seems to be around -15 at the max. Do I really need to worry about an 87db drop, or should I focus more on a drop of around 60 (putting it at -75 db)?

Here's some charts showing what I mean. For the untreated room you have to bring it out to about 4000ms to see the end of the mountain. This are all with 1/12 octave smoothing.

Default Fuzzmeasure graph of untreated room:

Fuzzmeasure graph of untreated room at -75db:

Default Fuzzmeasure graph of TREATED room:

Fuzzmeasure graph of treated room at -75db:

Hope all this makes sense. Looking forward to your suggestions.
