HyperWhistle Review: Hands-on Testing

Whistles are one of those gear items that does not get discussed much. It may not be as cool as a knife, or as fun as a tool for starting fires. But over the years I have come around to the importance of having such a simple tool in my pack. 

HyperWhistle

Whistles are lightweight, compact, and can be carried from on keychain, lanyard, or stuffed in a pocket. Their value comes from its ability to produce a very loud, distinctive sound while expending little effort. Whistles can be used to signal for help from long distances, used as a communication device between members in a group, and to scare off wildlife. 

In this article, I will be trying out the HyperWhistle. I have known about this product for some time and was reluctant in purchasing it as I figured it was just another whistle. Well, it is not just another whistle and to find out why let’s get into the review by first seeing what the whistle has to offer. 

HyperWhistle Review

Style 

The first thing to notice is that this whistle does not look like other whistles. Most whistles are flat and small in appearance, especially around the mouthpiece. The HyperWhistle’s mouthpiece is quite large and round. Its body is also quite large and features a tri-frequency design.

Material

This whistle is made from Anti-microbial composite and constructed for all weather conditions. This material also makes the whistle naturally buoyant.

Sound

Capable of 142dB, the HyperWhistle is advertised as the loudest whistle in the world. It can be heard up to 2 miles away and even works underwater.

What’s Included

When you purchase this it comes with one HyperWhistle, a lanyard with an easily detachable plastic clip, and a pair of soft ear protectors. 

Color

The HyperWhistle does come in two available color options. Black or orange. 

Testing 

The first thing that I noticed after opening the package was that the whistle came with a pair of ear protectors. The company is either covering their bases in helping to prevent hearing loss or they are trying to tell me that this whistle is very loud. Probably both and I should have taken the hint at this whistle’s capability, but I didn’t. 

After removing the contents of the package I quickly attached the black lanyard to the whistle and took it out to my garage to try it out. Mistake number one. I placed my lips on the mouthpiece, sucked in a lungful of air, and blew. 

The loud, high pitched sound that was produced actually made my face scrunch up and caused me to drop the whistle. Luckily, it was attached to the lanyard which was hung around my neck. Okay, so don’t use whistles in enclosed spaces. Duh, you knew that but moving on. 

Next, I moved out into the wide-open space of my backyard. Thinking that this was going to drastically reduce the sound I once again ignored wearing ear protection. Mistake number two. I once again placed my lips on the mouthpiece, sucked in a lungful of air, and blew. 

While the sound that was produced was not nearly as cringe-worthy as it was in the garage, it was still piercing and loud. And I mean LOUD. Several dogs throughout the surrounding area began barking. I think they heard it as well. 

Tri-frequency Design 

The way this whistle is designed looks a bit weird when compared to other whistles. From what I can tell it is three whistles in one. There is one mouthpiece but three individual side ports where the sound comes out. Interestingly, when I blocked one or even two of these ports, the whistle still worked. Just at a more diminished capacity. 

Water Test

On the back of the packaging, it notes that the whistle is naturally buoyant. I love gear that floats because accidents happen and over the years I have dropped numerous items in the drink.

To simulate dropping this whistle in a pond, river, or lake I filled up my kitchen sink. I then held it precisely two feet above the water’s surface (this measurement doesn’t really matter or have any bearing on the test) and released the whistle from my grip.

After breaking the water’s surface and sinking a little, the whistle came back up and floated. Unfortunately, it only floats for about ten seconds. I tried this with the lanyard attached and detached. I also tried dropping it from various heights. But the result was the same. Once the whistle became waterlogged, it slowly sank to the depths of my sink. Boo!

Water Test – Part 2

Sometimes there is a wealth of information on the back of products and I was surprised to find out that this whistle works underwater. I am not exactly sure how it does this but of course, I had to test this out as well. 

I used the same super sophisticated testing grounds for the underwater test as I did the float test, my kitchen sink. Now before you get your hopes up let me just say that no I did not take any pictures of this test. At least not ones I am willing to share. 

Okay, onto the testing. With the sink filled up, I placed the whistle in my mouth, took a huge breath, placed the whistle underwater, and blew. No sound. I tried this several times with the same result. I produced no sound but made a lot of bubbles. 

Hmmm. I decided to take it one step further. I thought maybe the whistle needed to be further underwater. So I took off my glasses, placed the whistle in my mouth, filled my lungs, stuck my head underwater, and blew. For the sake of bringing accurate testing results to the readers of this article, I repeated this process several times. I was only able to produce the slightest hint of a chirp. My conclusion from this highly scientific test is twofold

  1. The whistle works underwater but I am doing something wrong
  2. The whistle doesn’t work underwater and someone somewhere is having a laugh picturing people like me trying to use this underwater. 

*Edit. After a little bit of research I found a demonstration that showed this whistle does work underwater.

HyperWhistle Pros and Cons 

Pros 

  • SUPER LOUD! 
  • Incredibly affordable 
  • Feels durable
  • Comes with a nice lanyard and ear protectors (wear the ear protectors!)

Cons

  • Does not float on the top of water
  • The mouthpiece is larger than most whistles
  • Does require a little more air than other whistles to reach its potential 

Verdict

This is the loudest whistle I have ever used.

There is no doubt in my mind that when I blow into it if someone is within two miles of me, they will hear it. I am disappointed that the whistle doesn’t float and that it doesn’t work underwater.

To be fair, I do not know when I would ever use it underwater. I just thought it would be cool if it did work. When considering the low price point, the 142 dB range, and its ease of use I would recommend having a HyperWhistle for everyone in your family. In fact, I am going to be purchasing another one. But next time it will be orange. Thanks for reading and remember to wear ear protection!
