Acoustic Weapon Can Kill!

Regular readers will know that yours truly is obsessed by bass and boom. I find stories of underground explosions from the Mad Scientists I know utterly gripping. I have experienced a Sonic Boom from a big supersonic plane. I have been in a cave underground in the sea and felt a One Hertz pulse through a rock tunnel that got smaller…with me bobbing around in the cave beyond it! But above a certain level a sound pressure level wave front becomes an explosion and will tear you apart. I am gripped by the physics of this. Where does dB SPL go to Blast Overpressure? Anyway, one of my feeds is a thing about new acoustic products and this came up. It uses an explosion of a mess of cheap volatiles and is about crowd control. I am allowed, having asked to show you two paragraphs but I heartily recommend you follow the linkie and read the rest (as long as you promise to come back y’all!) on their own site as per clicky and read is how their site writer earns his crust!
It gripped me….

“Originally, the Thunder Generator was used by farmers in Israel to scare away birds that might eat their crops. Recently, Israel‘s Ministry of Defence has approved a license for the Israeli technology company ArmyTec to market military and paramilitary versions of the Thunder Generator. The company hopes that the cannon, which was originally developed by Israeli company PDT Agro, could have applications in crowd control and border security.”
And
To generate the shock waves, the cannon uses a mixture of liquefied petroleum, cooking gas, and air. As the fuel travels through the cannon barrel, it detonates and intensifies until it exits, producing a series of rapid-fire, high-velocity shock bursts. The shock bursts can be calibrated and programmed for different purposes. According to the company, the system can generate 60-100 bursts per minute, with each burst travelling at about 2,000 meters per second and lasting up to 300 milliseconds. The resulting extreme air pressure and sonic boom effect create a double deterrent to rioters and intruders.
