Couple of quick questions from a new user (me). :dumbcrazy:
I plan on using the DBX mic for full 20Hz to 20KHz measurements, and I'd like to know if the mic is to be used with the tip pointed to the ceiling or at the speaker.
I'd also like to do some averaging of the responses taken in a 3 foot radius around the prime seat. I'm wondering how this works. I know that REW will do the averaging for you, but once you move the mic to a new position wont the level change? For instance, if I take measurement A at 12 feet from the speaker and measurement B at 15 feet, I assume that the overall level will drop by a couple of dB at the 15 foot mark as compared to position A. Are the overall level differences accounted for by REW when it calcs the avg? Or do I have to adjust the level to 75dB each time I move the mic? Am I over-complicating things? :dizzy:
Also, does REW allow you to assign a weight to each of the measurement points when averaging, so I can give more weight to the measurement at the sweet spot than I do the others?
Thanks in advance!
