Most people's voices annoy me

Ok so I hate the sound of most people talking, it really gets under my skin for some reason. Mostly because they just sound so stupid and annoying, and they talk about dumb things or personal things I defiantly did not want to know. Why? Why do you have to be talking about your period or your sex life out in public? I'm not one of those snobby people who thinks it should be taboo or never talked about, but there's a time and a place. And just the sound of their voice alone just drives me bonkers, especially because the heavy accents people have around where I live that I find very annoying in the first place. I usually try to wear headphones to avoid hearing other people talk, but I can't wear them all the time. I DON'T FUCKING CARE! I want to yell at people next to me just carrying on about the dumbest things, I always feel like I'm dragged into people's conversations when I can hear them. So is it normal that the sound of most people's voices really annoy me?
