I mentioned my "Mega T" in a response in a post and feel that member "Mark" got some good preventative info. I want everyone to know there is T beyond T. It's big, it's horrible and scary and you don't want it. I'm talking about folks like me who diddle with loud music and should know better. After about an hour of loud music a few years ago, I had to walk out and leave my musician friends on their own. I was sitting at the organ and just couldn't take it anymore. Marshall stacks, miked drums and LOTS of monitors were eating through my plugs and protective headset. I thought I was doubly protected. I tried to lie to myself that night and thought I could get away with it. I should have known better. One thing I've learned for sure, if my T settles down, It can come right back where it left off, even years later. I KNEW this, but playing music at this place sounded like too much fun. I'd been living with T already for a couple decades, trying to be careful. It was just too damn loud. I waved goodbye, and took off with my headgear still on. When I left, I stood outside hearing my ears ringing like never before. It was way worse than any after-concert damage I ever had. I knew I was in trouble. I drove home, quiet and spooky and my wife knew something was wrong. I could hardly hear her talk. I woke up to the worst morning of my life. I was half dizzy, my usual high pitched T had sunk down in frequencies to an annoying whistle or trumpet like sound and LOUD as hell in each ear, BUT the two separate sounds were NOT in tune. It was maddening and LOUD. So loud. I wanted to run or scream or cry... a 35 year old man. Then the worst part, my girl and wife were talking, and I started talking and all sounds were distorted as if I'd truly blown my eardrums out. Now I'm thinking, "Was it worth it, for a few loud songs?" I thought it would settle down during the day. It didn't. I was scared, real scared. I'd NEVER heard anything like this. For the first time I was also experiencing the throbbing that comes with this kind of damage and found that stuffing cotton in my ears took away some of the throbbing. People at work noticed this change in my personality. I was quiet and scared and anxious. I had hope that it would settle down, though. So for months I wore my cotton and continued to hear the 'evil horns' in my head and everyone's voice sounded like a monster movie. And my ears throbbed. It went on for two years. Very slowly it all went back down to my normal hiss and squeal. Voices sounded clear again, but I still can't sit in an acoustic music setting without my cotton. And sometimes now just pulling masking tape off a spool it too much!! If you want to experience a taste of Mega T (and I don't think you do), go in a music store, talk into a mike going through a distortion pedal, then have a guy with a trumpet on your left and a bugle on the right and tell them to blow different out of tune notes and not stop, then have a guy poke your eardrums with the tips of drumsticks. That's MEGA T.
