Interesting idea. This is definitely one of those concepts that could be polished and expanded on. At first I was a little confused but when I was able to listen into the conversation from the air vent I started seeing the bigger picture. Also synthesizing the audio procedurally is super cool! If you haven't you should look up how star wars created the original sound effect for light sabers. Really opened my eyes to the limitless possibilities of sound design. Overall great idea just needs a little polish to really pop!
