What is the loudest thing on the streets? I've always thought it was a pulse jet organ car I saw at Burning Man, but this thing here might give it a run for it's money. I'm not exactly sure what the overall purpose of this vehicle is, but it is interesting looking.
The large horn in the front is a Kahlengerg S-6. From the website:
This is the largest air horn in the world. It was built in 1984, the only one of its kind, and won the competition among ship horn manufacturers at the Philadelphia Maritime Museum in 1985. It is 7 feet long, with a 35-inch bell and a 17-inch diaphragm. Weighing in at 267 lbs., it can be heard for 12 miles on land and 25 miles on water, when operating at full pressure (250 psi)Write in with comments if you've experienced this.
