Why do large crowds sound more like a garbled roar or crackle as opposed to screaming and actual cheering

198 viewsOther

I know that at concerts when a large crowd cheers loudly it’s heard more as a distorted roar but i’m curious as to why this happens. I’ve been to concerts where it’s a scream (eg when taylor swift came on stage) but I still heard it as a loud, overpowering roar and crackle. Why does this happen?

Several reasons: 

Sounds at a distance have poorly defined transients, so sound blurry. When you have lots of people cheering, you really only hear a mush of sustained sounds. The sheer number of people also makes the sound very complex and confusing to the ear, so it might appear more like a roar.
