[QUOTE="Ivan Beaver, post: 82075, member: 30"] Re: Listening Get Together Most 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. [/QUOTE]
