Storm Whistles - The Windstorm - Yellow
Model - The Windstorm.
Colour - Yellow.
The Storm All-Weather Safety Whistle is the loudest whistle on the market - 130db.
Creates a clear, high frequency sound, with a power rating over 75% greater than other referee and safety whistles.
It's unique patented design allows it to be heard under water, up to 50 feet, because the sounding chamber forces all water to be purged when the whistle is blown.
Responsive - Emits the loudest sound with the minimum effort, even for someone who is short of breath.
Ergonomic - Fits comfortably in your hand and to your lips.
Fits easily into a pock or purse, or can be worn on a lanyard.
Adopted by Military, Police, Lifesaving & Security Forces worldwide.
With a standard whistle, non-productive high frequency (over 5000 hertz) and non-productive 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.
