We could not resist using our new Sound Level Sensor at some local sporting events this past fall. The first graph shows the sound levels measured at about halfway up the stands in Autzen Stadium during the first half of an Oregon Ducks vs. Utah Utes football game.
The graph below shows sound levels measured during a Portland Timbers Major League Soccer game at Providence Park. Data were collected in the “Timbers Army” section of the stands, which is renowned for its loud cheering and singing. Can you answer these questions based on the graph?
