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

173 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?

Lower frequencies travel further than higher ones so the overall tone is lower. Men’s voices are generally lower and louder too which contributes. If the crowd is all girls and young women then the tone is a lot higher.

The thousands of different sounds people make all at the same time become indistinct unless something is keeping them together like a beat or a tune – in which case it becomes more distinct.
