Second Loudest Handheld Whistle in the World: The Windstorm™ Safety Whistle delivers a powerful up to 123 decibel blast, making it one of the loudest whistles available — second only to the Storm®. Compact, lightweight, and easy to blow, it’s built for serious safety situations on land or underwater.
Designed for military and marine use, Windstorm combines extreme volume with ergonomic comfort and waterproof reliability.
Why Choose the Windstorm™ Whistle?

123 dB High-Power Sound: Produces a sharp, penetrating tone that travels long distances and cuts through wind, surf, and background noise.
-
Waterproof & Functional Underwater (Up to 50 ft): Fully waterproof design works even after submersion — ideal for divers, swimmers, boaters, and rescue signalling.
-
Patented Dual-Chamber Harmonic Resonance Design: High and low frequencies combine into a focused, powerful single tone with enhanced amplitude for maximum attention.
-
Includes a pea in the upper chamber that creates a distinctive trill: unmistakable and attention-grabbing.
-

Most whistles lose power when wet. Windstorm™ performs in all weather conditions, including underwater environments.
Test Results
The Storm whistle is twice as loud as any other mouth-blown whistle in the world. Initial testing was conducted by the Hearing Conservation Programs Inc., who tested the decibel rating of various military, sports and survival whistles against the Storm whistle. These first tests were performed in a sound proof booth at a distance of 15 feet with the whistle being blown by mouth, and had a number of variables, such as the person blowing the whistle and the accuracy of the sound level devices.
The second set of tests, conducted by the Central Institute for the Deaf, were performed in open air at a distance of 15 feet, 25 feet and 50 feet. Here the whistles were attached to a constant air source which was adjusted to the normal blowing strength typically generated by the mouth. The sound the whistles made was then analyzed by computer, using a double blind technique, detailing the amplitude and signature of the sound created.
With a standard whistle, nonproductive high frequency (over 5000 hertz) and nonproductive low frequency (below 2000 hertz) sounds are created. Because of the patented harmonic chamber that is unique to the Storm whistle, these high and low frequency sounds are recycled and focused into our extremely loud single 3150 hertz frequency of double the standard amplitude.
The focused 3150 hertz frequency was generated intentionally in accordance with government recommendations that showed that the 3150 hertz tone is the most readily heard over the noise of motors, crowds, and explosions.
In all these cases, test results showed the Storm whistle as being twice as loud as the other whistles.Presently, the Storm whistle is being used by these groups as a personal alarm where an extremely loud alarm is necessary.
