give me 5 minutes with that diesel engine powering the siren and I'll have it tuned to 150DB easy. In 10 minutes I'd have it turning so many RPMs the sound waves would cause an avalanche on that cliff face

Spin that baby like a Leslie and get some great Doppler effect!

A lot of years ago I think it was the French that experimented with a whistle powered by a jet engine as the source of the wind that produced about one or two cycles per second sound waves and it gave people 5 miles away diarrhoea and shook tall buildings

I'd like to own one either buy it or build it figure out how to make it sound like the flight of the Valkyrie then drive it through every city in the USA to wake up the woke. But knowing me as well as I do I'd probably just use it to really tick people off
