Answer 1

In exactly the same way that a single eardrum can perceive the multitude of sounds.

The different sounds layer on top of each other, when they reach a microphone the result is one single vibration pattern that is a combination of all the sounds.

That same pattern when sent to a speaker recreates the sounds.
