‘The Kansas City Star brought a hand-held sound-level meter to Sunday’s contest. The opening kickoff sent the needle past 108 decibels at front-row level near one end zone, similar to the volume of a rock concert. Halfway up Section 116, cheers for the Chiefs’ first touchdown – a 67-yard pass play to Dante Hall – reached 117 decibels with celebratory music piped in. Fireworks made the meter peak out: 126 decibels.’
