Not sure what category this question fit into...I was trying to explain to my wife what an SPL meter does, when she said "Let me see it," and then she proceeds to scream right into it! This is the standard Rat Shack analog model (the meter, not my wife). She maxed out the needle at over 120 dB from about a foot away. It seems to be working just fine now, but this is sensitive equipment and I'm wondering if it's accurate now. Anyone know?
