How does the averaging time work on the 372 SPL Computer?

The 372 SPL Computer can be set to 1, 2, 4, or 8 and average together the number of samples to make a gain changes. After a calibration the sample buffer is cleared and set to the same relative level taken during the calibration. In other words if the 372 is set to 4 samples and calibrated at -30dB relative and during the first sample it reads -20dB it would average -20dB, -30dB, -30dB and -30dB to determine the gain change.
