I don't get agitated, but loud speaking people can be annoying for sure. Some folks just speak out too loud to others in their party or group shall I say. It's like they want to be heard above others as if they hold special importance. And then malls can be too loud as well. I read recently not only is the world becoming louder, but night time lights are over taken darkness. Like even from outer space. Not like what our ancestors witnessed. I was up in Canadian wilderness alone, and I promise you could not see your hand in front of your eyes without some lighted tool. I would turn on and off my head lamp, and I stand behind this statement.
