Then you come back with: "but you speak in a way that more people hear you than intended.."
You just changed what I specifically said so it would fit your narrative. Yes, you can be in a bar and think you're talking quietly, but the 3 pints and 2 shots you've consumed means that you're still yelling, just means you're a drunken fool. If you're in a restaurant or some other public setting while sober, you can actually talk to someone without the rest of the public hearing.
