Hi Bill. I'm sorry about asking this question again! I actually forgot that I asked this earlier. I just got confused because a friend stated I had to use the mic vertically to get the correct readings and so I second guessed my self, again...onder: Sorry-please disregard and no, now I am not going to remeasure. Only thought I had to and it would seem I do not need to.Hi Bob,
Didn't you like the answer Wayne and I gave you last month? What are you trying to measure now? Wayne's second link in particular discusses how the ECM8000 characteristics vary above 3kHz between horizontal and vertical, so if you are measuring higher frequencies than that, you need to use the orientation that matches the mic calibration file you are using, and the generic file was was generated horizontally.
