The WindStorm whistle from the American company Storm uses the principle of the so-called Helmholtz resonator – you have definitely blown into an empty bottle and amused yourself with the sounds coming from the bottle, and that's exactly it. The bottle functions as a resonant chamber. And finally, someone thought to use this principle, specifically Dr. Howard Wright in 1988.
The whistle is indeed very compact and very lightweight. Thanks to the special construction of the resonant chamber, it provides very high performance, the second highest in the world, even when wet, damp and even underwater, where it can be heard at a distance of a little over fifteen meters.
WindStorm is used by safety agencies, such as the police departments of New York City, Chicago or Atlanta, rescue organizations like the American Red Cross, and branches of the American military, e.g., the Coast Guard. It is also perfectly applicable in the field of personal safety.
