Sunday night was the 46th Superbowl played between the New York Giants and the New England Patriots at the Lucas Oil Stadium in Indianapolis, Indiana.
The National Institute for Occupational Safety & Health (NIOSH) who are based in Atlanta, Georgia set up a Twitter stream (#noiselevel) and asked anyone who was at the game to measure the noise levels using apps on mobile phones. They also had someone at the game who had a proper noise dosimeter.
This person measured the noise level at 107dB(A) LASmax when the Patriots scored and you can see this on a video here.
In 2006 we visited the San Diego Chargers to see a game against the Cleveland Browns and we used a Cirrus CR:110A doseBadge Noise Dosimeter to measure the noise levels over the game.
