Re: Listening Get TogetherMost real measurement platforms offer various forms of time windowing-sample averaging etc. Some are better than others-for example with TEF you can be running a shop vac next to the mic and it will give you good data-YES I have done it.With others you can do more averages-so the noise starts to "fall out". Each time you double the averages you gain 3dB in S/N ratio.Why are you worried about reflections and room modes-if the cabinets are "immune" to those?The phase trace will show/tell a lot in that regard.And of course SPL measurements are only good if the mic has been RECENTLY calibrated (like right before the test)-NOT calibrated when it was shipped.
