I just started noticing the ringing, you same sound after firing a gun with no ear protection but it does not go away. The irony of it all I take good care of my ears! I do notice the sound does disappear if I yawn and hiccup or burp at the same time while keeping my mouth closed, and my hearing gets amplified at the same time. If I focus on T it reminds me of the pirate joke, ya know he walks in the bar and the bartender says you know you have a steering wheel on your lap, and the pirate says arrr it's driving me nuts! and it is, any help besides the audio stuff?
