[QUOTE="alanB, post: 33026, member: 431"] I think you are missing the point (although I know very little about this so I may well be). All I intend doing is adding acoustic treatment (foam damping etc) to my room and measuring the improvement in an attempt to remove the wishful thinking element (although I have to say the final decision will be made by what my ears tell me not any graph) - hence my question about whether calibration is required. I would expect an uncalibrated mike to be able to pick up "a reduction in modal decay time and the levels of the nulls increase in level relative to the peaks to create a flatter response" - my way of saying the same thing was as you quote me :D. Because I will simply be subtracting the before and after plots from each other to get the net effect of each change, absolute calibration doesn't seem necessary to me. But hey I only started learning about this stuff yesterday or so my question/assumptions may be completely screwy! [/QUOTE]
