I can be alone in a crowd because, while I can hear people talking in a room with a lot of background noise, I can't follow the conversation. I can't understand what they are saying.
That's the same issue I have, just without the ringing, so far. It's bad enough that if I'm watching TV and my wife turns on the dishwasher, on the other side of the dining room, I have to turn the TV way up to be able to hear anything more than gibberish. Hell, sometimes just the background music in a show makes it hard for me to hear what's being said. In crowds, I still haven't figured out how many times I should ask, "Huh?" before I just pretend to know what someone said, use their facial cues to laugh or not and them just move on. Haha...
What's stupid is I can hear most things very well. Even very slight sounds. I just can't separate the sounds from each other when they're all jumbled up. AND, my 15 year old mumbles at me. That drives me ******* nuts, and she gets irritated with me always making her repeat stuff. If she'd just speak up and not say random **** with background noise, we'd be fine!
