Those who watched the the Sunday Night Football game between the Atlanta Falcons and the Green Bay Packers might have noticed something different, other than the obvious (the obvious being the new Mercedes-Benz Stadium as a whole).
The match itself played out almost exactly like the NFC Championship game, with the Falcons dominating and the Packers not being able to score much until they were faced with soft zone defense in garbage time. The difference was the sound omitted throughout the stadium whenever the Falcons made their way into the end zone (and it happened a lot) — the sound of a train horn ringing amid the celebration.
