A video with only Phillies crowd noise, plus a sound level meter, will show you how loud Citizen Bank Park can be

Arizona Diamondbacks pitcher Merrill Kelly dared to question how loud it can truly get at Citizens Bank Park when he wondered if it would be louder than a World Baseball Classic game he was at.

The answer? Well, I don’t have a scientific one. But on Tuesday, as the Phils put together a 10-0 blowout win in Game 2 of the 2023 NLCS, we at least know how loud it can get.

In another one of those videos in a series of only-crowd-noise clips, you can hear how fans go nuts as Trea Turner hit one out. And MLB had a sound level meter to give you a number.

It got up to 108 decibels, which is — per the Hearing Health Foundation — the equivalent of “gas powered leaf blower/ice cream truck” and close to a “dog barking in ear.”
