We had our annual valley firework show tonight. I had to work during the evening, but fortunately I got a chance to get out for a few minutes and watch the show. The fireworks were probably about a mile away, and yet you could still hear some of the explosions at a fairly loud level. It got me to thinking, what kind of SPLs are we talking here? I mean if you were within say 50' or so of one of these high explosive fireworks? I would think they would have to be very very high. Anyone have an idea? 130 dBs? 140?
