Since it seems the mods aren't going to approve my first post, I'll try again.
I work as a sound engineer, which is funding my CPL. Hearing protection has always been important because of my job, and often I do leave a little bit of my hearing at every gig I do.
That said, even with constant tinnitis, I passed my class 1 hearing tests fine, with no "concernable hearing loss".
Musician earplugs are the way to go, with decent ones providing even frequency response from 50hz-16khz. Moulded ones are fantastic and very comfortable, but some
stole mine last month (who'd wear someone elses earplugs anyway) so I'm back to generic ones. The model I'd recommend are called ER20's from Etymotic
. There's a few Australian dealers, give ER20 a search on eBay and you'll find the generic ones, or ask your audiologist at your next medical renewal and they'll take a mould and get some made for ya.
