Between loud music and almost 5400 hours on a C-130 I’m surprised my hearing is better than that of most 18 year olds. I can hear conversations in the next room without any difficulty, as well as the trains that are several miles away, and everything in between. And I’m pushing 70.
What?...............................
My deafness was caused by years of B-52 engines, then years of steel shop work, followed by years of power plant operations.
And I wore hearing protection!
