I read, for a long time, what the "world's loudest whistle" was, and, found out about the Hyperwhistle. I can say, as the headline suggests, that this fits that bill, and then some.
Pros:
- This is easily the loudest whistle you can buy, so it is suitable for all sorts of applications.
- Price is fantastic for what you get.
- I tested this, on a long, pier, which is in a very rural area, with a friend, and the claims about distance, are accurate, if not a bit undersold; this could easily be heard much further away.
- Does not require an immense amount of lung power to use, whilst still being ear-piercingly loud.
- Unbelievably durable/well crafted - I wish more plastics/polymers were made to this standard, or, all were. This whistle can take a fall onto concrete from 3 stories, and it can be left outside (neither of those are anything I'd recommend), for 4 days straight, in a predominately saline environment, which does a good job at least tarnishing almost anything in less time, and, this shows NO signs of damage or anything; it looks brand new still after all of that.
Cons:
- I have absolutely nothing negative to say about this, and I have tried to find something....
- It isn't a "con", but, it sure would be nice, if this had the "NHL referee style" two finger ring guard, somehow implemented on future designs, or perhaps a variant product. The lanyard can do that job as well though.
All said, this is a very very very, loud, whistle. I could see this being easily used for a means of self-defense, that would alert literally anyone, and buy someone time to escape whatever danger they are in. If more lifeguards had this - maybe they do use these, no idea personally - that also would be a very effective and affordable way to save lives, and, again, alert anyone on a beach. This is something that I would suggest anyone who wants to go hiking, or is into ANY form of exploration, be it nature, urban, etc. to have with them, as it really is tough enough to withstand anything, it CAN be used underwater (tested this myself, and even remembered to use earplugs), and, well, to avoid being more redundant, this could easily save your life, and it is so well made, that I've already been suggesting this to other people.
I have nothing negative to say about it at all, because it's got the perfect price point for the quality, and accurate, if not modest, claims they make in their advertising for the product.
10/10 - 5/5 Stars - Excellent product, which I HIGHLY recommend!

Mission accomplished and my beloved feels safer with it. It is a most unusual looking, sturdy whistle but as long as it scares the crap out of a coyote, it doesn’t have to look purty. It just has to keep my other half purty.
Top reviews from other countries
One of the standout features of the HyperWhistle is its incredible sound output. A sound pressure level (SPL) of up to 142dB is eight times louder than your typical whistle. This makes it perfect for various situations, whether boating, attending sporting events, ensuring life safety, camping, hiking, or even police use.
The durability of this whistle is also worth noting. It is built to withstand all weather conditions, making it a reliable companion no matter the environment. Whether it's raining, snowing, or even underwater, the HyperWhistle will continue to function flawlessly.
I also appreciate the attention to detail in the design of this whistle. Its unique radial tri-frequency design ensures that the sound is carried efficiently and effectively, allowing it to be heard from a distance. Additionally, the whistle is naturally buoyant, adding an extra layer of convenience for water-related activities.
The HyperWhistle comes with reusable hearing protectors, which is a thoughtful addition. This ensures that you can protect your ears while still enjoying the powerful sound of the whistle. The easy clip-neck lanyard is also a handy feature, allowing you to keep the whistle within reach at all times.
It's worth mentioning that the HyperWhistle is a patented design (US8925478), which speaks to its uniqueness and quality.
Impossible de sifflet pendant 5 secondes à pleine puissance, il faut souffler très fort pour avoir un son fort qui décroit en moins d'une seconde.
Je ne pense pas que ce soit le meilleur choix pour un randonneur tombé dans un ravin: Blessé, affaibli, il n'aurait jamais la force de souffler dans ce sifflet.
