Does the decibel measurement vary much depending on what part of the field the measurement is taken?

I'd like to know how we truly compare. We are gaining respect for being a difficult place to play, but I think there might be other places that are louder etc.

Me just thinking out loud: This is anecdotal, but my dad who's getting older usually doesn't go to late games and his tickets go to those of us that are younger and louder. I think in general, that would cause late games to be louder. I wonder what the decibel difference is between day games and late games?
