Police, jet engines and noise.

[StRaNgEdAyS]

As some of you will know, I am planning to build using a pulsejet engine.
I have touched on the subject that they are loud a couple of times, but in my research to find ways of extending the valve life and other possile improvements to the design, I came across somthing that puts it brilliantly.

Jet engines are very loud. Rocket engines are deafeningly loud. Pulsejets of the same thrust levels of similar rocket engines redefine loud. They are painfully loud. Even very small pulsejets. Certainly, if you have noisy neighbours who won't shut up, get yourself a pulsejet and fire it up. If the noise doesn't permanently shut them up, the flames from the exhaust probably will.

The first time I ever fired one of these up at home I even had the police come around to check it out! 3 cars loads! :whistle:
Of course now I live in a smaller town, with only 2 policemen..... I have yet to introduce them to the noise these things make..:gig:
