The Windstorm Whistles
Tests show that the Windstorm™ whistle produces a sound which is more easily heard when compared to other popular whistles. Tested by an independent research team under the most demanding scientific methods, the Windstorm™ competed head-to-head for loudness against the most popular whistles in the world. Data derived by powering 4 test whistles at a constant pressure and strong effort prove its loudness.
