I was doing a little research for a friend and came upon this ref. volume levels in movie theaters. Seeing as I have not been in one for maybe 15 years I was way off on my 'estimate' of the potentially damaging volume levels therein...This article is more than sobering and though @jeffie7 posted reference to it in a thread in late March, I thought it a good idea to highlight the facts more clearly. An extract below:

Dangerously Loud?
"The thing about loud exposure is it doesn't have to hurt you to be damaging to your ear."— Dr. John Bedolla
How loud is too loud? Dr. John Bedolla, an emergency room doctor with Seton Healthcare put the impact of loud movies on the ear in context, "Human beings did not experience sound louder than 90-100 decibels for much of human history until the invention of gun powder and machinery. So, for the vast majority of human existence, our ear has never adapted to loud noises."
Dr. Bedolla referred to a recent report in the Ear, Nose and Throat Journal showing just how loud movies have become.
"Certain types of high-spectacle movies, such as Transformers, have decibel levels of 90 for almost the entire movie and have decibel levels of 120 for significant periods and at some points get to 130 decibels. Now 130 decibels is a jet engine at about 10 meters," says Dr. Bedolla.
That last sentence is stupefying...Come to your own conclusions!
