Review: Well, my tinnitus is worse; that is proof enough that this thing is LOUD! - I'll start by saying, do not be like me; this is not something to foolishly test out indoors, because, you easily run the risk of making yourself deaf, or, at least having some serious hearing damage. Don't be like me, and use this inside, as excited as you, rightfully, are, to test this the second it is delivered. 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! - RevengeOfThePiff
Review: Well-built and very loud - So, this guy is VERY loud. It has three chambers, unlike the majority of whistles, which have one. I liked that it was sturdy and made of thick plastic. The three chambers and the thick plastic mean it won't fit comfortably in your pocket. It comes with a wrist lanyard, but depending on what you're using it for, you might want to purchase a neck lanyard instead. If you're going with a neck lanyard, you REALLY need a break-away lanyard. Not just for this, but for any neck lanyard. The last thing you need is for somebody to run by and get tangled up in it, or have it snag on a fence or brush. It's a good-looking whistle, but it won't look as nice on a strangled corpse - go with a break-away.

## Questions & Answers

**Q: Both the storm whistle and the hyperwhistle claim to be the world's loudest. Which one's louder?**
A: Storm WAS the world's loudest whistle for many years at a 130-132db output, however HyperWhistle moved the bar pretty significantly 142+db when it was released a year ago and Storm continues to use their claims inappropriately. 
Sound power is measured in db which is a logarithmic scale +3db is 2x soundpower +6 = 4x,  +9 = 8x etc. so in measurable and quantifiable sound power, HyperWhistle is 10db louder than Storm, generally that is greater than 8x soundpower higher than the storm! 
Virtually 100% of the population consider a +6-+8 as more than double the perceived loudness to their ears even though the sound power factor is far greater. 
If you look at the construct of the HyperWhistle is is actually three chambers specifically tuned so they reinforce each other in an acoustic Heterodyne function producing not just the primary fundamentals of each tuned cavity but also the mix or combination or sum difference of each chamber in close and intimate acoustic relationship.
HyperWhistle is very unique in this acoustic signalling field and was born from its military/defense counterpart HyperSpike products.
Hope this helps...

**Q: Will it scare aggressive dogs?**
A: Not 100% sure, but it definitely startled me the first time I tried it. 
I now wear mine while out walking my two small dogs, who have been 
attacked more than once by aggressive dogs. The price is very reasonable,
so much so I will most likely buy a second one to store in my survival pack.
second one to keep in my survival pack.

**Q: Will this deter an animal? Was recently attacked and bit multiple times by a feral dog while riding my mountain bike. Looking for a non-lethal weapon.**
A: From what I hear in the customer video it’s not remotely as loud as the air horn/dog horn. I have used the dog horn to deter dog attacks. Works perfectly.

**Q: Will this whistle survive scuba diving?**
A: Totally Yes to surviving scuba diving. There are no moving parts in the whistle and the body is made of heavy durable plastic material. There is nothing that will be damaged by water, even at extreme depths. It is also self clearing/draining of water: there is no closed chamber to fill with water like a standard police whistle with an internal ball. And YES, it is loud. You had best plug both ears with your fingers when you blow it, or you will experience a sound level overload in your ear drums that is similar to that heard near a jet engine. Way beyond hearing damage level if continuously exposed...
