MLB isn’t just experimenting with fake crowd noise for TV broadcasts, they’re pumping it into the empty stadium.

Mets reporter Tim Healey shared some video from from a Mets intrasquad game, where the sound system played a ‘low murmur’ of a crowd, followed by a cheer when the hitter made contact and a louder cheer when the outfielder made the catch.

Other teams are experimenting as well – in fact, MLB has provided teams with an ‘approved soundtrack’ of cheers and even a few boos.

The 2020 MLB season is set to begin next week on July 23rd.
