Lugnut, I'd add fire alarms to your list. In my workplace, we have unannounced fire drills about once every 3 months, and you have to walk right past the blasted thing to get to the back staircase. I'd imagine it's somewhere in the range of 130 dB and is a continuous blast! My Rat Shack SPL meter is now tucked away in my desk in anticipation of the next drill, along with some cotton balls. I'll try to take a quick reading, but my guess is that it will be off the meter. Your advice is critically important! When the sun blinds you, you naturally cover your eyes until they can adjust and never look directly into it. So when your ears are exposed to extreme volumes in continuous blasts, cover them and turn away!
