As the Red Sox prepare for their season- opener on July 24 against the Baltimore Orioles, without fans in attendance, the team has been testing piped-in crowd noise at Fenway Park.

In a video tweeted by NESN’s Tom Caron on Friday, the sound of murmuring fans and music can be heard blaring out of the stadium speakers.

With the presence of spectators in many ballparks being restricted due to COVID-19, MLB sent audio to all thirty teams, according to Caron.
