Given that I’ve told half a dozen people to go listen to this in the last week, it’s probably worthy of posting. Our friends at Radio Lab had a great piece a couple months back where they look at the Bible story where 7 trumpeters bring down the walls of Jericho. They ask the question, how many trumpeters would it take to bring down a wall like that? Along the way you learn quite a bit about acoustics, the science of sound.
It’s about 15 minutes and available on their website.
