I've just discovered that I've got tinnitus. :( What I hear, 24 hours a day, is a tone-ish noise (noise, that sounds pretty centered around a tone, but it's very hard to pick out a frequency) It's roughly as loud as my room airconditioner 10' away. I don't know what I could have done to piss off my ears, I've never been much of a loud music junkie, never had any extreme pressure events... Shooting, with ear protection, maybe twice a year (I AM an american after all) I also have what my audiologist calls a "moderate" notch of 60dB (!) at about 3kHz Since when is a 1,000,000 / 1 loss "moderate" ? I bet if I applied that loss to her salary, she'd think it was pretty significant. -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.2 for non-commercial use iQA/AwUBOPSHgoFlGDz1l6VWEQLklwCgpaDRG2UUp5zBpNLx/K052EHzY7oAn1Y/ nLHtIf4SciecmMvqMiYKIo2n =kYzM -----END PGP SIGNATURE-----
