Storm All-Weather Safety Whistle
The Loudest Mouth-Blown Whistle in the World

The Storm whistle is engineered for extreme conditions and maximum volume. Designed with a patented harmonic resonance chamber, it delivers a focused, powerful 3150Hz sound—twice as loud as any other whistle on the market. This makes it an essential tool for divers, lifeguards, emergency responders, and outdoor enthusiasts.

Key Features:
✅ World’s loudest whistle – Heard over half a mile away
✅ Patented harmonic chamber – Recycles nonproductive frequencies into a powerful 3150Hz blast
✅ All-weather durability – Operates in mud, snow, sand, and even underwater (up to 50 feet)
✅ Self-clearing design – Blows water out of the chamber with each use
✅ Perfect for noisy environments – Easily heard over motors, crowds, wind, or explosions
✅ Made in the USA
✅ Power rating 75% higher than standard safety and referee whistles

Tested and Proven:

Initial testing by Hearing Conservation Programs Inc. confirmed its superior loudness in controlled environments.

Independent lab tests by the Central Institute for the Deaf showed Storm produced a sound with double the amplitude of competing whistles.

Designed to government frequency guidelines for maximum audibility (3150Hz) in critical situations.

Whether you’re diving, hiking, boating, or signaling for help in an emergency, the Storm whistle is built to be heard when it matters most.
