However nowhere does the Bible specifically say it was the sound waves themselves that caused the walls to fall just that it happened while the people shouted.
Anyway the archeological evidence seems to indicate that God sent an Earthquake at exactly the moment they shouted, and that 8m high 2m thick mud-brick wall on top of the 4m high revetment wall and embankment fell down and created ruble high enough for them to climb over the embankment and stone revetment wall.
Notice that the strength of the wind isn't relevant; ANY wind would eventually bring down the wall as long as it respected the oscillation os the wall.
Hebrews tells us "By faith the walls of Jericho fell down, after they were compassed about seven days." God certainly could have used any means he wanted, but clearly points to the faith of the Israelites as the cause of the wall falling down.
This seems to me that God chose to work supernaturally in this case.
There is even a section of the wall left standing (that was buried beneath layers of dirt of course) in the north section of the city that Rahab's house must have been built against.
The evidence corroborates Joshua's story, but the problem is Kathleen Kenyon made errors in the dating of the pottery of the period and claimed that Jericho was destroyed 150 years before Joshua got there.
"Then the lamb ram sheep horns began to blow The trumpets began to sound Joshua commanded the children to shout"Some of the comments left by believers are amusingly ridicules. which is why troops are taught to break stride when crossing bridges. I believe that God works within the laws of physics because he created physics. I liked the ol' hole in the shield bit there at the end but I think atmospheric conditions could have played a large role.
I'd love to know how they feel about Jonah & the great fish(whale)or is this too far out for some. I make no claims that my belief is anything more than my belief. Wouldn't a wind current change the way sound travles? There are many Great comments here and I think that when combined, to me, the bible story seems more than plausible.
Literal translation will always be disproved by science because they did not understand science the way we do.
The lyrics of the song say it wasn't just trumpet players but ram horns, trumpets and children shouting... For the destruction of the Boughton Suspension bridge (1826) from mechanical resonance induced by troops marching in step see:
Actually the city had two levels of walls, an inner and outer wall or upper and lower wall, and both fell (it was built on a type of hill or tell).
And they found that the city was totally burned after the walls fell and even the full pots grain was burned(which is an unique archaeological find because usually after a siege there would be no more grain left or the conquering army would plunder the grain).
In this case the strength of the wind is vital and that's the case explored in the show. ...imagine the wind is smart and instead of blowing hard and continuously, it watches the oscillations of the wall to learn where the is the furthest point of bending back of the wall.
