Acoustic propagation. I design large format PA systems and as a result need to know both how to make sound and stop sound at a large scale. It is entirely possible and actually relatively easy to be super precise with where sound goes or doesn’t go. The problem is cost.
So a lot of people are aware of active noise cancellation that you find in headphones nowadays, that works in large scale as well. The first time that type of technology was used was in the greatful dead’s wall of sound. The problem is it’s expensive to do large scale.

How do I subscribe to acoustic propagation facts?
Just message me, you’ll get some!
