Author Topic: Can "anyone" install a Dolby Atmos system? Martin Brooks Jedi Master Film Handler Posts: 900 From: Forest Hills, NY, USA Registered: May 2002 posted 07-04-2014 07:34 PM                        quote: Harold Hallikainen Is anyone aware of public limits to minimize hearing damage? I've seen occupational limits by the US OSHA. Generally, they establish a dosage where 100% is 85 or 90 dBA continuously for 8 hours. Higher levels increase the dosage faster. But, these are occupational, not public. Also, most movies are not 8 hours long. I think there are plenty of venues in the U.S., especially music clubs and concert venues, where the sound levels routinely exceed OSHA levels and potentially cause permanent hearing damage. I'm amazed that there hasn't been a class action lawsuit by employees who work in such venues. "On the side", I create websites for musicians and also do photography for the sites. Of the musicians I work with, I don't know a single one who doesn't have hearing damage and/or tinnitus and these aren't exactly heavy metal bands. I developed tinnitus after attending a concert with a cold some years ago, even though I used hearing protection. I no longer have ringing, but I think there is still perceived noise generation. I love great theatrical sound, but I find too many theaters playing the audio at absurdly loud levels. A lot of this happens in the mixing room where the film's director insists on everything being loud, but I really don't want to be yelled at in every single dialog scene. Even in big action scenes, while I like impact, I don't need the entire scene to be beyond the threshold of pain. Both in the music and theatrical industries, it seems like everyone has forgotten what dynamic range means and that you create emotion by the differences in sound levels, not by incessant loudness. I never thought I would ever have to wear hearing protection while watching a movie, but I have.  |  IP: Logged Lyle Romer Phenomenal Film Handler Posts: 1400 From: Davie, FL, USA Registered: May 2002 posted 07-05-2014 10:56 AM                     quote: Martin Brooks I think there are plenty of venues in the U.S., especially music clubs and concert venues, where the sound levels routinely exceed OSHA levels and potentially cause permanent hearing damage.

I haven't ever paid close attention but I assume that the employees in those environments wear ear protection of some sort.  |  IP: Logged
