Just finished watching Dunkirk IMAX 70mm at Metreon 16 in SF. Loved the movie but holyshit, this was definitely the loudest movie i've ever heard, and probably the loudest thing i've ever experienced. There are periods of sustained loud sound lasting 3-5 minutes at a time, and not just an instance or 'bang'. I calibrate my sound setup to 75-85 db, this must have been 100-110 db. In every sense of the word, it was deafening and uncomfortable. I get immersion and all but yeah this was too much for me... prior i've never found a movie or concert/club was too loud, a first for me.
So i really recommend bringing ear plugs just in case you experience immense discomfort like i did... wish i knew before hand.
EDIT: my intent is not to deter you from watching this movie. It's masterfully crafted and 70mm is mindblowing. Nothing that can be captured at home. Just in case it gets uncomfortablly loud for you, you'll be glad you brought ear plugs.
