Basically the title. If you have a bunch of people who have similar max volumes chanting in unison, it’s much louder than a single person chanting.
If no one is louder than the rest, why is the net effect still much louder?

Sound waves are additive. The amplitudes of sound waves can be made larger or smaller through interference with other sounds.
Same reason to candles of similar size have a greater light and heat output than just one.
You’re putting more energy into the system, so you get more energy out of the system.
Sounds are waves. If you push water away from you to create a wave, it won’t be as big as when you do it with someone else. The waves combine into a bigger one.
You ever been playing in the water at the beach ducking under waves? Sometimes one wave catches up to another and it becomes one big wave. It’s kinda like that, because sound is just a wave (pressure wave) propagating through air.
