HOW IT WORKS
Air Flow in
The Tri-Frequency Design is the key to our Whistle's Output. We have carefully engineered a specific frequency for each chamber and in all unison they are harmonic's of the same note. HyperWhistle has patented this design. With this idea, HyperWhistle is able to reach a much higher output, up to 3x the amount of the normal Mouth-Blown Whistle.
HyperWhistle, was born from a US Navy Officials request for a louder whistle that could be used by the flight launch crews on the decks of US Aircraft carriers, where idling jets are present and the ambient noise level exceeds 125 decibels.
More than 2.5 years of engineering effort ensued to arrive to the World's most efficient and Powerful mouth blown whistle.
HyperWhistle also works in any and all Weather Conditions, including Underwater.
