Storm All Weather Whistle

The Storm All-Weather Safety Whistle is the loudest whistle on the market. Its 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. It's perfect for divers, lifeguards, and for recreation! Creates a clear, high frequency sound, with a power rating over 75% greater than other referee and safety whistles.

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. They 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. The whistles were attached to a constant air source which was adjusted to the normal blowing strength typically generated by the mouth. The sound 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 the 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.

    Sounds really loud as advertised but found it awkward to hold, so have now gone for a traditional shaped whistle

    Loudest Whistle On Earth!

    Posted by Abdullah Guri on 6th Mar 2022

    I got this whistle for camping in case of any emergency and boy is it loud. I have to say, I'm pretty sure it is one of the loudest if not the loudest whistle on earth. The shape and design fits perfectly into the hand, it is very easy, light and comfortable to handle and hold. I chose to purchase this whistle as orange because in case of an emergency, orange is very visible in things like dirt, soil and leaves. Overall, it is a great product and I am very pleased and impressed with it! P.S: Don't blow indoors, it will blow your ears off!

    Storm All Weather Whistle

    Posted by Charlie on 15th Feb 2022

    Only gave this 4 stars as I was expecting it to be louder (Might be getting deaf in my old age) still very loud and easy to see if dropped, light and a very good size if you need to use it with cold hands. As ever outstanding service from the guys at HH.

    Many options . . . One solution!!!

    Posted by Mark on 10th Jul 2016

    I did the rounds, looking at many nesting cups for my Nalgene bottle, I looked at a number of products (irrespective of cost) and settled on this one. And am very happy with this cup/lid set up. Like all outdoor equipment, it's all too easy to damage or loose, so whilst I could pay £40 quid or so for a titanium mug, but could not see the benefit for such a small gain/loss in weight for my kit.
