What is the most accurate way of measuring sound levels? Example, if there was a rock gig or rave going on down the street how can I measure that level... accurately. Let's say I DON'T have professional equipment.
I do have a Behringer MX2004A mixer and a Sony Minidisc recorder. Can I use a simple mic like a SM57? Also what sort of readings should I take? If it's digital it would be below 0dB and analogue would be above 0dB. Am I right? Any feedback is much appreciated. Thanks.
