I measured the sound levels with my Larson Davis 720 logging SPL meter, and the average level over two and a half hours (including the trailers) was 84.7 dBA with a highest maximum level of 99.4 dBA. The level exceeded 89.4 dBA 10 percent of the time, 83.4 dBA 33 percent of the time, and 78.2 dBA 50 percent of the time. The average level is barely within the OSHA standard, which many experts—including myself—believe is too high to begin with. In any event, I wore my custom-molded earplugs (-25 dB) throughout and Bose QC15 noise-cancelling headphones during the really loud parts, of which there were many, especially low-frequency blasts from the subwoofers.
Your statement about OSHA didn't match with what I remembered when I was in school…. so I looked it up again. It was still the same. These levels that you quote, which I believe are correct, are way below OSHA maximums. Now a 2+ hour rock concert would come close or probably over in many cases.
I calculate/estimate around a 15% dose. Of course if you were exposed to high levels in your workplace during the rest of the day… you might reach significant levels.
I understand that it might be argued that the osha standard should be beefed up… but to say these measurements are "barely" within the OSHA standard is misleading, IMO.
On other notes:
I, at first thought there was way to much high frequency effects… but when I thought about metal bending and ripping apart and rubbing together in these battle scenes, it probably would have a very high frequency and abrasive sound. You know, like heavy metal music, but with no bass guitar. It seems right to me, you shouldn't feel warm and fuzzy after a star ship is nearly destroyed.
