I don't think DB meters are terribly honest. Or perhaps the people giving the numbers aren't. For instance the chiefs claim something up in the 130's as their loudest. This season during the playoffs the loudest that I saw it reported at was something in 110's. I don't know how you could reasonably explain that discrepancy in volume given that those playoff games were really some of their most important games in history. Essentially I think they've inflated the numbers they've recorded. Arrowhead is still loud but I think they've been a bit dishonest with their numbers. I have the same suspicion for Oregon and Clemson. They give numbers that are a good 20 Decibels louder than Neyland, the Swamp, Happy Valley, Kyle Field. And I just don't buy that they're could be such a gap in volume. I'm not saying it's impossible for them to have the record but I'd say the numbers they report are highly improbable. I think they either measuring in a different manner or are simply falsifying their numbers.
