my SPL meter can measure average SPL for any length of time, as long as the batteries don't run down, something like 60 hours if i remember right.
some day i will measure one of those "noisy" movies to see...
maybe Saving Private Ryan. Or, what about "The Mouse that Roared", that would be great, right?

for now, my guess is the majority of movies would have average levels of some 80-85 dBC SPL.

i think the measurements should be done with the "C" weighting; if anyone knows otherwise, pls tell me.
