This is definitely stupid, think I’m missing something.
If I say something at 60 decibels for example, the person I’m talking to will hear it at that volume (ignoring the sound lost over distance).
But if a crowd of people say something at 60 decibels, it will be louder to the person hearing it.
I just can’t get my head around why, since they’re all talking at the same volume as the single person. What amplifies it?

Sound is a wave. Waves interfere – they act alongside other waves in the same spot. When you have two sound waves passing through the same space, the pressures add together, and you have a louder sound.
