Two weeks into a season largely without in-person fans, the NFL has changed its stadium audio policy, allowing teams to crank up the volume on fake crowd noise beginning in Week 3. As NFL Network's Tom Pelissero reported Friday, the league has informed clubs that any stadium housing fewer than 2,500 fans can now play pre-recorded game-day audio at up to 80 decibels.

The NFL previously required all stadiums to play team-specific audio that it distributed to each club, with a maximum volume of 70 decibels.
