Way too loud. I frequently ask the manager to turn down the volume at local theaters. Sometimes they actually do it, and I make it a point to thank them later. Once, I was told that, for IMAX productions, there is no local control over sound, including volume...they can't turn it down. He was probably lying, but he did suggest avoiding IMAX if I was "sensitive" to loud sounds. I also don't go in the theater during the previews, which are much louder than the feature.
