The introduction of artificial crowd noise into NFL broadcasts is a complicated process. It involves trained audio engineers working a soundboard of pre-recorded audio clips that are divided into different categories and are able to be ratcheted up in intensity based on the game situation.
The implementation was uneven at best in Week 1 but it went better this weekend. For example, fans watching at home as the Eagles were blown out by the Rams were treated to a familiar sound: the home crowd booing Philadelphia’s poor play.
On at least two occasions, viewers heard Carson Wentz and the Eagles offense get showered with boos—once after a failed third-down conversion and then after Wentz threw a pick in the end zone.
