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... ## Customer Reviews ### ⭐ Highly overated product *by S***R on 29 May 2024* Do not buy it at all. 100 times cheaper whistles are much better than this. ### ⭐⭐⭐⭐⭐ Review *by A***R on 28 March 2024* +++ TRES BIEN +++ ### ⭐⭐⭐⭐⭐ Review *by M***G on 22 October 2023* This whistle is not your average sports whistle; it is super loud and has a range of up to 2+ miles, an impressive eight times the range of an ordinary whistle. 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. ## Frequently Bought Together - HyperWhistle The Original Worlds Loudest Whistle up to 142db Loud, Very Long Range, for Referee, Coaches, Instructors, Sports, Teachers, Life Guard, Self Defense, Survival, Emergency uses - LuxoGear Emergency Whistles with Lanyard Safety Whistle Survival Shrill Loud Blast for Kayak Life Vest Jacket Boating Fishing Boat Camping Hiking Hunting Rescue Signaling Kids Lifeguard Plastic 2 Pack - Fox 40 Sonik Blast whistle (orange black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/253336597-hyperwhistle-the-original-worlds-loudest-whistle-up-to-142db-loud](https://www.desertcart.com.cy/products/253336597-hyperwhistle-the-original-worlds-loudest-whistle-up-to-142db-loud) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
