My wife turns on CC when I ask her to turn the volume up. She gets mad that I make her repeat herself when I'm cooking because I cant hear through the (fairly quiet) range fan. My life once consisted of nothing but trucks and machinery, but nothing too extreme, just lots of intermittent and impact noise. I waited too long to start carrying hearing protection. I think I was 23 when I caught on, but the damage was done.
That's why I counter it with heavy metal. I've got a system for that. A sound system, that is! I feed raw steel through a calibrated EQ and a BBE expander to a rackmount power amp running four Klipsch full-range speakers and two separate subwoofers so that I may indeed tear the roof off the mother.
...As in the mother ship, if'n I'm making my funk the P-funk. I take a break from metal to get funked up. Which leads to Infectious Grooves, which leads back to metal. It's a vicious cycle.
In reality, I have that sound system in the shop so that I can listen at healthy levels. Good gear dialed in the way I like it to sound works even better than cranking it up.
