Az- If *you* had an open mind, you'd actually try a sound level meter before trying to come up with a whole bunch of excuses why it *doesn't* work.
I bet your the same guy who refuses to use a thermometer to measure a human's temperature too because:
1) Each person has their own inherent body temp, so how can you know what yours should be anyway?
2) Each thermometer is manufactured ever so slightly differently than any other (manufacturing tolerances) so how could you ever know that the real temperature is what you're measuring?
3) How do you account for the "contact resistance" of the thermometer against the object you're trying to measure? Each person's skin *does* have a different ability to cool itself which affects that variable.
4) As we all know, thermometers measure differently according to ambient temp, humidity, and barometric pressure. Hmmm... Got to take those into account too.
Yet in spite of the fact of how unaccurate I just proved a thermometer to be, they have been used for decades to measure a human's body temperature.
*Don't* use a sound level meter. Don't matter none to me, or the countless others who have gotten good results with one.
BTW, I like fresh broccali with a little melted cheese on top...
