Thanks for the info. I tried it and it should be "A over B" in the trace arithmetic since we need to get the power ratio between ANC on and ANC off. (Not subtraction)

Thanks for the very helpful info. I wonder if we can get the "delta value" (ANC on vs off) inside REW application. Or we have to export the measurement result for offline processing?

Does anyone use REW to measure ANC Headphone performance? I've got a miniDSP EARS. I think maybe SPL measurement by sweep sine can be used. Connect the speaker out to some noise speaker and measure the SPL on EARS with ANC headphone on.
