If you're a sports fan, you know (and possibly even love) that dull roar of the crowd in some of America's biggest stadiums. The familiar noise can be heard at almost any sporting event... that indiscernible combination of thousands of people talking, cheering, yelling, and taking selfies.

But this video from the Chelsea Football Club in the UK is like nothing I've ever seen before. In this clip from a goal scored by Ji-Sung Park, you can literally hear almost 42,000 people scream the word "YEAH!" all at the same time. The cluttered buzz of thousands of voices all come together to form one word, and it's amazing.

We also heard a similar effect during the 2015 ALDS, when Jose Bautista crushed a long go-ahead three-run homer in the 7th inning of Game 5.
