I'm curious what everyone on here is using to measure sound level? I'm going out an a limb and assume mobile phone apps. As someone who has spent a good deal of time designing and measuring sound levels on cell phones, I would caution that these are devices are not intended for any sort of measurement accuracy, and probably have little correlation to on actual absolute value.

That said, clearly there are people at each events that are uncomfortable; I've experienced some piercing high frequencies at the events as well, and agree that the venues and sound folks should be more cognizant of sound levels through the venue.
