Audio Project Idea

I could ask maybe 5 or so different people to tell me some cool story about something that happened in their life. I would play them all back kinda at the same time, so you would be hearing all the stories at once. I wouldn't want to completely drown out each story, but I want to make it hard to listen to any single story without focusing pretty hard on it, so you would sort of switch between the different stories as you listened. I wouldn't actually line up the stories based on when they started, but instead when they ended, so they would all end at the exact same time, leaving sudden silence.
It's kinda like when you're in a room, and you can hear all the different conversations going on, but you're not completely paying attention to all of them.
