I suspect it’s something to do with sounds waves so have flaired as physics, but not sure?

When 100 people sing together, they really do produce 100 times as much sound. But our ears do an interesting thing — they make big differences in sound seem like smaller differences in loudness. When there is more sound, you can hear that it’s louder, but twice as much sound seems less than twice as loud. A choir of 100 singers *feels* only 5 or 10 times as loud as one singer.
Why do your ears do this? Because it’s incredibly useful that we can hear really, really soft sounds and we can also hear really, really loud sounds. Did you know that the difference between the loudest amount of sound you can hear and the softest amount of sound you can hear is like the difference between the weight of the Empire State Building and the weight of a fly’s wing? That’s pretty amazing, right? Your ears squeeze down that difference so you can handle it. There is no scale in the world that could weigh a fly’s wing and also weigh the Empire State Building. But your ears can.
