Property developers well never, not in a million years, build enough new housing to make their industry significantly less profitable.
The only solution is local government building social housing and being as good landlord at low prices. Good luck with that, America!
Definitely, but you only ever perceive all that because of the one-dimenaional way your eardrums vibrate, and they vibrate because the air next to them vibrates. If we make the air next to your eardrums vibrate in the same pattern they did when the band were performing, you will hear and perceive the same sound as the band made.
You should be aware that an amplified band is only ever making sound at you through a bunch of speakers whose only function is to vibrate air in a one dimensional pattern.
Separating that all out into different instruments and people and timbres etc is the clever bit, and your brain does that, not the speaker, and you largely learned it as a child.
