Sound, Joshua and the Battle of Jericho

Joshua and the destruction of Jericho

The Bible tells the story of the fall of Jericho:

Joshua 6:1 – 27:

“Now Jericho was shut up inside and outside because of the people of Israel. None went out, and none came in. And the Lord said to Joshua, “See, I have given Jericho into your hand, with its king and mighty men of valor. You shall march around the city, all the men of war going around the city once. Thus shall you do for six days. Seven priests shall bear seven trumpets of rams’ horns before the ark. On the seventh day you shall march around the city seven times, and the priests shall blow the trumpets. And when they make a long blast with the ram’s horn, when you hear the sound of the trumpet, then all the people shall shout with a great shout, and the wall of the city will fall down flat, and the people shall go up, everyone straight before him.” …

Apparently, the attacking Jewish forces used SOUND (their marching, their horns (shofars) and their voices) to knock down the walls.  Who knows?  Given the force of sound, maybe it is a true story??

Here you can see and hear a shofar. Maybe if you had a lot of these, you could make a sound wave that could knock over a wall?

Here you can hear the song “Joshua Fit the Battle of Jericho”, sung by Paul Robeson, the famous African-American and Communist singer.

And here you can hear a podcast that looks at the sonic explanation for the collapsing walls.

Here you can read about mechanical resonance. And here you can read about how mechanical resonance (from the six days of marching around Jericho) might be the cause of the collapse of the walls. Very interesting theory!

Here you can read about acoustical resonance.  Perhaps this explains, through the blowing of the shofars, the failure of the walls.

Who knows what actually happened!  But – as we know, sound is powerful stuff – maybe Joshua had invented the first LRAD!!  Or was just really lucky with the marching and the horns resulting in mechanical and acoustical resonance!
