As i was listening to drone music the siren goes of. Disturbing. Nice to know it works.

If the american signal hurricane siren were boosted to 4-tones.

Partial from a test of an outdoor warning system amongst brick buildings. Civil dense siren, public address message, construction equipment and springtime songbirds.

Moderate rainfall with civil defense (air raid) sirens wailing and rotating and low rumbles of thunder. Recorded about an hour before a major tornado struck the area.

Here's a old geiger counter with the tube held by a radioactive test sample, probably / hopefully fairly well decayed. Audio is recorded by hanging the headphones on a blue bluebird condenser, as the headphone connector is an unusual 1/2 inch threaded thing. The serial number of this unit is 71605.

Inspired by a drawing posted on airradsirens. Com some time ago, a huge siren that is a hybrid of a thunderbolt and a hurricane siren, supercharged by a large industrial air compressor. You do not want to be anywhere close to this beast when it goes off!.

Disclaimer: this may be loud. Check your volume. This sound is an experiment i did for a short film my crew and i are working on. I wanted to see if i could make a warning effect like the civil defense messages that play on the radio for storms and other emergencies, so i recorded my voice, and pitched it down, equalized it, put it through a high pass filter and lo and behold, i think it sounds pretty darn close. I then coupled it with a couple alert tones from my local noaa / nssl station and this sound was born. This effect could be used for an apocalyptic scenario or civil unrest, riots, looting, or anything else you desire. Not required, but it would be cool to hear if you use it for anything. Enjoy!.
