I would think it is louder on the sideline of a football game, especially in a college game than the stage of most Metallica concerts. Also coaches are having full on converstaions, with thier staffs, and they cant scream what they are replying back so everyone can hear.
OK......I'm not trying be difficult and your propbably right but if so, why have one ear fully exposed to all the noise? T o me hat would like having two vocal monitors pointing at me. One sounding hevenly and the other sounding like an old car horn going off. I don't get it. Every time that i watch a Packer game I wonder.
