I don't know how my environmental exposures compare to others, however I think they are significant. Since I was a teen, I've photographed and made high quality "purist" stereo recordings of locomotives, primarily steam, but all types. I've mixed FOH sound beginning in the late 80s thru today. I've mixed in every venue size with the exception of stadiums. In the early stages of high end auto sound, I had a '76 Chevette, w/ a high power bi-amped, Alpine based, sound system. It was a non-resonant, "hi fi" rig, with a custom sealed 10" IB sub in the back, and up front 5" low mids, and a combo 1.25" dome highs, and ribbon super tweeters. The dome and ribbon were a combo, self contained piece, that I surface mounted on the dash and toed in pointing at me. I was one proud owner and everyone that had the pleasure of hearing it couldn't believe the detail,...top to bottom. .....Ok, point being, I listened loud and everything but the sub was very "nearfield"
I worked every concert, monster truck event, and NFL game, @ the RCA Dome (prior to it's demise, generally regarded as the loudest indoor stadium in the league) For the Colt's games I was in the bowl, high up in what we called the 'A" frame. It's where the NFL officials, team video, and pyro operators resided on game days, 8-10 people total. I stood between the clock operators and the scoreboard operator. My responsibilities were the play and game clock, scoreboard, and in house video rf distribution and TVs, including the ancient Diamond Vision screens. .....Once again, point being, that stadium was extremely loud, much more so than modern stadiums, including Lucas Oil Stadium. Oftentimes we'd have tell yell into each others ears, only having to repeat it again. Very, very exciting atmasphere however.
Powerful auto sound, Railfan, FOH mixer, racing fan, Stadium events of all types, construction, I've tried to protect my ears every chance I can, but I'm just sayin'...
btw...,in construction there are a variety of very loud things, but has anyone here ever heard a steel chop saw? Carpenters use them to cut metal studs and some very rough pipe fitters may use them to cut angle iron etc..., regardless, they can be DEAFENING!
