The whole idea of anyone dictating standards has always been amusing, especially if you've been in this business for any length of time. Regardless of whether you have (had) THX certification or brought in the latest gizmoes for fine tuning the equalization in your theatre, it still seems that every room has its own personality. Do you really think you can walk blindfolded into a "calibrated" 500 seat auditorium, and then a 50 seat viewing room and not notice a difference? How many of us have light meters on our benches, so we can check for standard illumination levels every day? Y'know, if you don't have one, you're probably cheating your audience.
Then there's the myriad differences between individuals. We are just not built the same. I don't hear the same as you do... or Grandma does. So... who's to say that we're hearing anything the way a producer intended? Maybe he's burned his hearing out from years of headphone use. Wow... everything he creates is blasting loud! That might actually explain a lot.
With "standards" as a goal, at least we have a benchmark to aspire to... but maybe that's the way it should be left.
As for the obsessed out there, just remember that we went through this with CinemaScope, Dolby, digital sound and now this new stuff. In pretty much every case where new technologies came out, someone tried to limit access to those theatres that spent the money on the new gadgets. In pretty much every case, greed prevailed. Wasn't it a certain creator of space-based adventure movies that first tried to limit his films to those theatres that had installed Dolby optical? Same guy tried it again with digital cinema. How did that work out?
Regardless of the hype in the trades, I really doubt anyone here will ever be visited by a member of the screen or sound system police.
Interesting thought, though...
