I used the k371 sweep for calibration, then compared my shp9500 using the k371 filter, and my measure was half way between two professional grade shp9500 curves made on a Gras rig. Lol. Thanks

When you say divide them? You mean A/B rather than A-B? Would that work?. Maybe the calibration filter doesn't work like I thought in my message above? I asked chatgpt and it seems to be able to answer a lot of questions about REW and it said it was A-B. I see however are you the author of the...

Hi. Thanks for response. My understanding is I need to subtract them, so say my curve is 10db above the reference curve at at frequency a, the same at frequency b, and 10db below at frequency c, taking one away from the other would create a sort of - 10, 0, +10 offset to apply to my calibration...

Hi, I have built a DIY headphone frequency testing setup using a capsule mic. My "head" is a head sized block of wood and covered in paxmate. Shockingly it actually works pretty well! I have been runnin sine sweeps with various headphones at 90db @1khz normalization and the curves look similar...
