I am assuming I have been using those correction factors correctly.
As an example, if my reading at 25 Hz is showing -5db on the meter scale, my level is actually zero since the meter is insenstive at that frequency by 5db.
BTW, ignore the calibration numbers for anything over 9KHz, there's a big fall-off in mic sensitivity there. (Then again, unless you're testing tweeters, it's not a big deal).
Ted, the second post in this thread answered the question. If the meter reads what's in the first column, you must add the value in the second to get the actual reading.
Actually, I believe the test tones on VE (if they're like Avia) are low-frequency pink noise, random LF signal. It's my understanding that the RS meters read 2-3 dB low on such a signal, so you would add, say, 2.5dB to the raw RS reading to get the "true" level of the tones.
Are you absolutely sure about the corrections being built into AVIA?
The reason I ask is because I thought I read in one of Guy's post that he didn't use the corrections because he had know way of knowing what everyone would use as measuring devices. Seems like he used ETF and a preamp mic setup himself. I've also read where others are using Spectra Plus and they use the RS mic compensation for monitoring or recording AVIA sweeps.
