Re: SPL metering, logging, alarmThis question is related to what I originally started this thread for.I used an SPL datalogger to collect SPL readings every second for 45 minutes. I want to be able to present this data in a meaningful way. What is the difference between an arithmetic average of the values and an Leq, which I understand to be a calculation of what the SPL level of a constant sound over the same period would be? I don't want to skip any important math, and if necessary, I would be amenable to plugging in some calculus formulas into excel to get what I need.Just to be clear, the datalogger I used does NOT calculate Leq on its own.
