dailydriver, like a couple of the posters have said, it can be a strang mix.
I'm 47, 27 of those years being in the power, and I have always been careful (in 1990, there was no awareness in Oz, but as soon as we were aware, I was careful), and I stress to the younuns that they MUST be careful.
I rarely attend concerts, but got ribbed at Iron Maiden, for wearing earplugs...these kids will be talking on Wednesday about their ears still ringing...I remind them that one day it won't stop.
Had my hearing tested for work reasons the other day, and the hearing is still there, perfect at low end, and 10dB loss at the 6,000Hz and up frequencies, about par with my age, and WAY ahead of my industry.
The turbines ARE quieter than they were 20 years ago...the meter still says 110dB, I don't register the same.
