Over the weekend I attended a dinner in a ballroom with about 200 other adults. There was no music playing, but the talking was quite loud. I didn't have my ear plugs in and I stayed in the room for about an hour and a half. After I left the room I noticed my ears hissed more than usual. I kicked myself, not literally, for not using my earplugs. Today, I have a slight hiss that seems to emanate from my head and not from my ears. My left ear is my primary T ear. The varying tones that I would hear in my left ear have subsided. The course of any one person's T is so varied. I'm finding my current situation slightly more annoying during waking hours, but far less annoying when trying to fall asleep.
