Calibrate SPL meter with measurement mic?

scoring4films · 13th November 2009, 05:06 PM

Is there a way to calibrate an SPL meter with measurement mic? I have a new uncalibrated SPL meter and no access to a calibrated meter. But I do have a measurement mic! Any ideas/suggestions greatly appreciated.

thanks

where did you get an uncalibrated SPL meter? Don't they usually come calibrated from the factory?

It might be in good shape right out of the box. I saw a +/- disclaimer that made me think I needed to calibrate my radioshack digital SPL meter. But I took it with me to a screening at the tisch dolby theater in nyc and had the projectionist give me some tones while I sat 2/3rds back in the middle..

You need to go to a "Calibrated Dub Stage".
Follow the guide lines here:
NEW UPDATED Room Calibration for Film and TV Post - Digi User Conference

Look at the new Post on the Sticky and follow it.

Play back "Band Pass Pink" and adjust your meter.
