Using forty small, rectangular sensor hubs placed in casings under stadium seats at Sun Devil stadium, Arizona State University was able to turn a jumbotron cliche into a scientific measurement. In 2015, they collected sound data from the crowd using the sensors and represented the information on the scoreboard as a sound meter, said Assistant Vice President of IT Development at ASU Chris Richardson.
The loudest section of fans, as determined by the data, received a push notification from the ASU app on their phones.
“It’s scientific as well as it’s actionable response to those that engaged with the game,” Richardson said.
