Beaver stadium has gotten as loud as 145dB on game day. My ringing ears can prove that.
The loudest thing in the universe would occur on a planet with an extremely dense atmosphere. This would allow more particles to vibrate, and because of the increased density they would carry more "force" (sound) and strike your ear drums harder. It's really just dependent on atmosphere composition though.
