Well not that you can record a log with, you would have to jump up to one that had logging capabilities that start at a about a couple hundred. You could also look for a computer based program that could do that and run a measurement mic into a computer interface but, your still stuck with the same problem. Calibration. Without a calibrated microphone measurements are close to useless. There are actually some iPhone apps that record db history. That would be a really cheap way of doing it.
