My neighbor at 3 am.
Thank you for being the random guy who tested something like this. You may have saved someones life. Silly sounding I know, but I'm working on an emergency kit and you never know.
Appreciate the kind words...
The WW1 trench whistle is the whistle you want. It is an airfast whistle( that is a whistle with no pea; in my view pea whistles are too unreliable because as an experiment I purchased a Storm whistle and the pea kept getting stuck). It is nickel plated brass, reliable, super loud( it was heard 1.3km away). Forget about the others, my view is that plastic is plastic and it will eventually break down over time. A brass whistle won't.
This is true, someone was randomly attacked at my work place by a stranger si now we are all searching the internet for the best safety equipment.

As I have said, the WW1 trench whistle. I have tested it out in the field, in semi hilly country with scattered trees and the other person helping me heard it from 1.3km away. And he used an app on his phone to measure the distance.

Appreciate your notes on specific whistles location within the video... Cheers
Appreciate it
this is a lot more useful then the video.. but can you tell me which one was the best
i prefer ackme tornado 635 and thats the current one im using but if you are a starter try fox 40 series or other other ackme series that looks like a whistle and not weird shape but others will surely go for the valkeen cause its been gaining popularity lately and a little more higher decibals then the ackme tornado 365
I've had my classic fox40 since I was a lifeguard about 20 years ago! It's built like a tank! The only bad thing about it, is when my 7 year old finds it! 🥳
that's adorable lol
Also, thank you! I'm gonna get the Fox40 too
Thank you. I've been looking for something like this!
Thank you. Been looking at whistles for bird training but wanted to know the tone more than the decibel rating. This was perfect
HyperWhistle is very unique , it is a three primary different but related tones device tuned to a center at 2600hz and the Acoustic Heterodyne of the three tones produces a very rich in Harmonics natural warble without any need for a ball or pea in any chamber, it is the only product of three natural tones with this feature on the market...
thank you for taking yr time and helping us by guiding us on what will be best for all of us anf our safety
NP and my pleasure, always want to help folks in saving lives and in the marketplace we have today there is generally no policing of faux claims!
Another note: in addition to the request for a public version of the Excel spreadsheet, it would also be really handy if you could post an index of sorts in the video description with a listing of all the products tested and the timestamp where they are introduced.

This is *THE* definitive whistle review/data video. *_THANK YOU!_*
I appreciate your kind words...
We put a lot of attention to detail and science into this so that it would clearly stand out as the OBJECTIVE test and review as compared to the typical SUBJECTIVE review video as is very common in this category.
Virtually all of the other reviews were simple, blow a few whistles, and state which one sounds the loudest. that fails to ascertain true performance as can be backed up with the science of sound and acoustics. Glad you enjoyed it!
@@curtgraber I watched about 7-10 other whistle videos and still didn't find the information I was looking for, once I got to this video, I got every piece of data I needed, laid out and explained perfectly, and even data I didn't know I needed until you presented it! Right after watching this video I purchased 3 whistles based on the information found on the video, I saved this to my favorites to come back to, and deleted all the other whistle videos from my history. THANK YOU!
Excellent, excellent review. I was wondering if anybody had taken the time to do things professionally in this topic and this is great work. Thank you. I have the Storm. Very happy with it.
Thanks for the nice video!
It is very useful to compare different types of whistle!
I look forward to your whistle video!

Hi Curt,
Interesting test, I appreciate the effort. It's the sort of data I'm looking for while trying to pick the best whistle for sea paddling. However it would make sense to provide a link to your spreadsheet either as a download or at least as a screenshot. It's not really readable in your footage.
www.wattre.com/supporting-document-whistle-test
Awesome and extremely helpful video! One thing I'd be interested to know is SPL when blown lightly (i.e. easy of use for small kids). Specifically I am considering the Fox40 Sharx vs the Windstorm whistle and wondering if my 3 year old would be able to get more output from one vs the other? Thanks!
Greetings
Thanks for your input.
While that was never part of this test criteria someone may do a study of the output of lightly blown whistles or the threshold of whistle operation.
This particular study was to objectively score whistles for their max range potential based upon the science of the devices output frequency spectrum and the SPL as compared to the losses of air transmissibility of sound over distance.
I frankly would not hand any of these devices to a three year old or any child for that mater, they simply are not toys!
@@curtgraber thank you for the fast response! I appreciate your input. That is a reasonable and fair thought, and I guess I'd be much more likely to have my 6 or 10 y.o. wonder off than to lose the 3 y.o. I suppose I should have whistles with the bigger 2 and the wife while the little one is maintained in eyesight. Thank you again!
I'm pleased to see the venerable Acme "Thunderer" test so well. It is a classic and, therefore, the most familiar sound for a whistle. There's little mistaking it for something else.
Joseph
Appreciate your input and I concur Acme products are world renown and a great value!
The Acme Thunder sounds the best by far
The inventor J Hudson founder of ACME whistles invented the pea whistle.
Thanks for the video. I know what the meter read but the last one didn't seem as loud as some of the other whistles. Could it be the tone that affects my perception of loudness?
Greetings Informed
Thanks for your question it is relevant.
The audio track of the video was captured by a typical digital camera that has a built in microphone and a DCC (digital compression circuit) that is designed to enhance quiet sounds and limit loud sounds to create a linear audio track for common uses applications. the problem with those systems in play is the louder the sound near the camera the harder the DCC clamps the audio compressor circuit, we noticed the same when we mastered the video but instead of modifying the tracks which would have been noticed as well we decided to let the audio track alone and just let the actual measurement gear do the story telling for us in a scientific (objective) manner.
This same digital microphone DCC challenge is why you can't expect to use a free SPL METER app on your phone and get any real measurements if the source level is greater than about 115db infact the highest we have ever seen a SPL app register on a PDA phone is 130.2db which came from a source level that was simultaneously measured with the B&K meter at 153.7db so expect that type of anomaly anytime you would use a digital camera with a embedded microphone with any very loud acoustic source.
@@curtgraber Thank you for that explanation and taking the time to respond.
Wow, you covered everything! Awesome!
We tried to comb the entire market for the best of the best to include in this test Finale... Enjoy!
So sophisticated, very cool!
This is fantastic. Can anyone explain how to interpret the frequency numbers? It seems that the lower frequencies might carry better over distances (those air horns, for example). Also, I cannot read the table at the end on my small monitor - is that anywhere else? Thanks for doing this!
Greetings Mr Canoe
So there is much to learn about the mechanics of sound transmission over long distances.
You are correct lower frequency devices completely trump higher frequency devices when dealing with distances greater than 100m
If you look at the air damping factor, that is a fractional db loss per every meter of distance. So you capture the center frequency of any device (loudest tone in the entire spectrum captured from the device) apply the formula shown and it calculates the actual air damping factor, you multiply that times the distance, and add the spherical expansion spreading loss for that distance and you are left with the actual losses for that device over a specific distance.
Quieter (lower db) devices that produce a lower frequency center will naturally lose less db per meter of distance than higher frequency devices.
Another unique function of the spreadsheet is the ability for it to predict the exact distance a device can produce 55db which is the minimum sound level to overcome (5db over ambient sound level) the sound of nature (insects and typical wind rustling) noise level nc-45 or nc-50 in an average quiet woods.
Hope this helps your understanding of the properties of acoustics.
BTW i do hold the current Guinness World reccord for the most powerful electro acoustic long range acoustic device.

@@curtisgraber9946 Thank you for the information! Great Work!
How does room configuration affect these tests? Does reflected sound have no bearing? Would it not be more accurate to test these in an outdoor setting? Or in a room with accoustic deadening on the walls to prevent reflections?
I'm genuinely curious.
Greetings Daniel
Due to the video size limitations we set on this video production, we didn't show even 15% of the total testing that was completed over the course of a weeks effort to capture all of the data from the 39 whistles, it would have been well over an hour long video that virtually nobody would have watched through to the end.
We captured the Spectrum frequency performance and the Harmonic content overblow performance in one of our anechoic chambers that was shown in the video at the very front of the video.
The SPL 1 meter tests were taken in a pretty typical post-production room with 40% sound absorption (not seen in the video) in our media room.
If there was any minimal reflections affecting the tests it ultimately affected them all identically since the exact position and room conditions were used throughout the tests.
Attempting outdoor SPL performance testing on a large variety of devices over days of testing would have introduced: ambient wind/temp/outside noise levels challenges to the test mix, so we decided the fairest test was to test all whistles by the same subject whistle blower, in controlled conditions venue and extrapolate to distances with the captured data and 20-log (spreading loss) plus air absorption (damping) applied to the results to equally score the devices.
BTW a division of the US Gov accepted this test data as a standards function of qualifying mouth blown alerting devices.
I appreciate your valid question and I hope this clears up your curiosity...
@@curtgraber I did see the sound-dampened room in the opening seconds, which is why I was wondering why it didn't appear in the on-screen tests.
I appreciate your detailed responses and clarifications throughout the comments. It seems many of the questions arise from the video not being as exhaustive as the testing you did. Nevertheless your methodology seems pretty robust and the results reliable enough, even based on the video alone.
Today I decided to needed to get everyone I loved a good emergency whistle. This video by far was the most helpful. I appreciate it. I bought (11) Fox 40 Classic CMG’s right after this. A whole array of colors by the way lol Thanks again
You're very welcome!
Great work
First of all thanks a lot for making this video, I am considering the Nitecore NWS10, I need a very slim and minimalistic whistle for my keychain setup, and that one, dimension wise is exactly what I want.
Would you mind me asking your personal opinion on that specific one?
It would be used in a city environment and I am not planning on using it for wilderness survival.
Thank you :)
Greetings and thanks for the question.
Nitecore is a unique entry in this field as many of the whistles are quite large but needed to be to generate acoustic power, their market target is certainly not longest range or loudest performance but rather super compact and nearly indestructible construction.
from an acoustics performance scenario the device is scored with moderate overblow clean output and with our SPL test it hit a 117db a bit shy of their max claim of 120db but this whistle is .... Tiny!
A construction of alloy's that makes it virtually indestructible and its size is a big proponent to those wanting a keychain whistle that lasts forever.
If your target use is not in a survivalist use mindset and ranges of less than 300-350m in the outdoors (less in urban environments) is acceptable then it may be a great choice!
@@curtgraber thank you very much for such a quick and detailed response.
I'd say this answers all I needed to know AND more.
Considering the moderate distances I need it for, which are not even close to 300/350m I think this will suit me nicely.
An added information I can provide you with is that the latest version, which I believe is the one you posess (icy conditions rated) uses an alluminum/minium 🤣 resonator press fitted inside the titanium alloy body, the first version had a plastic one which fell out constantly and stabbed the overall reliability in the back!
Given I know for a fact the reliability is no longer an issue, and I know now it performs way beyond my requirements I'll pick one up and my "one keychain to rule them all" will be complete!
7+ years in the making and this is the final puzzle piece!
Out of curiosity how would you rate "ye' ol' 2 or 4 fingers inna mouth" whistle? Considering someone who does not have Armstrong's level lungs (trumpet not bicycle nor moon😁)
@@MrSwosh89 so a person whistling with either fingers or just mouth typically varies substantially person to person, I honed my skills as a young teen and became quite proficient but generally my measured performance is in the 121-123db @1m range with a center frequency of 4khz and a bunch of non-additive tonals and noise. others may measure better or worse, but one thing is for sure, a quality manufactured whistle can allow just about anyone to perform near to or exceed that level with no training or practice... Cheers
@@curtgraber Thanks for humoring me 😁 and good to know, if in a bad situation I'll resist the urge to look cool and pull out my nerdy whistle!
Science! Btw I somehow expedted you to be quire proficient at whistling 😁
Is the SPL on the chart for spacial pulse length ? Sorry I skimmed over the vid
Ryan
I used LCPeak methodology to capture the maximum swing capability of each device. Generally the RMS spl value will be 2-4db less, but this methodology shows the specific maximum value for each device compared on a NIST traceable certified meter calibrated with a NIST acoustic calibrated source.
mpravo bravo very good test mai fred
I'm looking for a very loud whistle and knew I could find some comparative at youtube.
But I expected the best one had been a large metallic whistle.
Any new candidate?
Greetings
We have been watching the market but no real new whistles or technology have come to industry. until there is new material to test the Ultimate Survival Whistle Test 2020 stands as is.
We are planning to have an update in 2022 if new whistles are available, and to pick a few up data on a few more missed in the 2020 tests.
Cheers

very good video!!!!
Is there a way the whistles could be "blown" by an artificial mouth carrying a stream of regulated compressed air at a representative breath pressure, to make sure each whistle is blown with exactly as much force as the others?
Greetings your question is appropriate, while every whistle was blown by the same test subject over many days of testing to create this data we also captured the overblow performance of each whistle which provided the maximum amount of energy available from each device while blown by an actual person.
whistles have several conditions and they follow these basic functions:
1. minimum air pressure/flow threshold for resonant oscillation of the Helmholtz cavity (quietest a device can sound)
2. maximum air pressure/flow threshold for the overblow condition of the Helmholtz cavity (ultimately the acoustic limit of the device at the fundamental frequency of its design)
3. spectral content (frequency) produced when operated at just under the overblow condition
4. harmonic content produced both even and odd order harmonics and their contribution to the device performance.
The test subject was chosen because he had the ability to blow nearly all of the whistles into an overblown condition (some literally could not be overblown with his tested nominal lung power of 1.15 psi@ 5.2l/sec flow rate).
While we could add a metric of how much SPL for how much air with a calibrated air source the maximum range performance scoring would be exactly the same as this is a test of maximum range performance and all whistles were blown at their maximum pressure and flow rate before they went into an overblow condition by the test subject.
All whistles are different, some are quick to threshold and make sound with little pressure and flow(these always overblow and have a limited output), others require significant flow and pressure to threshold but they quickly out perform as they generically have a much higher threshold for overblow. Only 5 test whistles in this list were incapable of being blown to an overblow condition by the test subject and the top performing whistle was the HyperWhistle with the loudest and least overblown condition and had the lowest specific center frequency all which contributed to it's highest scoring in this listing.
Is there a link somewhere? I can't read it on my phone. I'm sure a computer would be no problem
www.wattre.com/supporting-document-whistle-test
Thank you.
Thanks!!!
Personally, I have found that a handgun is much louder and more effective at getting attention than any whistle when it is needed most.
More specifically, both a 10mm or .357 magnum tend to be excellent.
Well how do you read the results ? 🎧🔊🔕 What whistle would you chose ? 👂
Real data. Love it!
We took this project on to help folks make educated decisions and eliminate the subjectivity in loudness and spectral content and useful range on moth blown whistles. when all the data was compiled it was obvious and intuitive to anyone interested including Gov. level entities who are not interested in Marketing Specifications but real data to solve problems and to buy the best products for specific applications. cheers!
this is exactly what i was looking for, holiday shopping for my nieces simple because i do not have to hear it. lol
Its always best when you don't have to hear it haha
So basically, most of the whistles did well except the cheap no-brand ones. There are of course variables. There's no way to measure how hard you blew each whistle. Location also has to be taken into consideration. The whistle that's going to be very loud in the open doesn't necessarily mean it's going to cut through the trees in a forest or mountains. My personal preference is the pear whistles because they're easiest to use.
Greetings and Thanks for your comments
the purpose of the test was to "objectively" qualify the whistles for longest possible range.
The spreadsheet stacks the performance criteria and scores them based upon their individual true maximum range, in testing we used the same individual to blow all the whistles and to blow them each at the maximum output they were capable of before overblow (harmonic shift) many of the whistles are just simply poor designs that can't be blown hard as they shift into a harmonic overblow (lower output higher frequency output) very quickly.
Interesting the whistles that were easiest to start to blow were always the ones that self limit due to an overblow shift, some whistles were extremely loud but require lots of pressure/flow to meet their max output thus less suitable for someone who made bad life choices or had some type of lung or diaphragm injury.
The test proves many things that are notable:
1. whistles that are easy to blow never produce long range output performance.
2. the lower the frequency of operation the longer the whistle carried.
In a woods the lower frequency performance is especially important as it is less attenuated by trees and foliage.
Not what I was expecting but very informative.
Glad you liked it! it is unique to look at typical common things in a scientific manner.
@@curtgraber At times some of us are looking for as objective review as possible. You did take the time and effort to provide us with as objective review as possible. I did not purchase the loudest whistle due to the fact that in many cases 120db (IMO) is enough to discourage a wood be attacker or even get the attention if you are in close range (ie parking lot).
What about wet performance? In a real emergency it’s going to be awful conditions. I want a loud whistle that works in wet and thinking about it when cold too.
Kelly
Generically most whistles work when wet or moist however if they contain a pea to generate a warble or modulation then those do not perform well when in freezing temps. metal whistles are also a challenge when in freezing temps as they can literally freeze to your lips.
Now this is a man that takes his whistles seriously!

Is this a fair test with reverberation of the walls?
Greetings
I appreciate your question.
Tests were taken in both an anechoic chamber as seen in the video intro (SPL, Frequency-Spectrum and Overtones capture) as well in a real room (SPL both LCPK, LCMAX results) identically in identical conditions for all whistles tested so that repeatable test results would garner a objective not subjective test result.
Clearly I could not show every test of every whistle in every condition and scenario and keep the video under 12 hours :) so the video captured the essence of the certified results tests (which took more than a week to complete) and published the results in shorter video format capable of showing the intended effort.
Wattre Inc. is an accredited NIST Certified acoustic measurement facility that is quite capable of producing real world testing of anything acoustic related and has been doing this for the US Gov. for more than 20 years.
It is a fair test to all products tested and the results stand as the best test ever contrived for mouth blown whistles and has been used internationally by 10's of thousands of folks in qualifying mouth blown whistles to date.
the Analytics really tell the story with Hundreds of Thousands of Viewers to date :)
Take care...
Great test lineup. Came here hoping to compare the Fox 40 Sonic Blast which claims 120db! Another high pitch whistle, so I can predict the range will be limited as well.
It scored #13 in this conclusive test and lineup, a great whistle no doubt but far from the most powerful units in the test.
It would be cool if you tagged whistles on timeline.
The hyper whistle must be the ones referee's use in massive stadiums with thousands of people,but is it louder than the trench whistle?
Not sure who all uses it , however It is the Loudest and furthest range of any whistle tested to date...
Definitely getting the ACME Thunderer
Excellent review. Would like to see the same review for 2021.
Noted! planning on an update in 2022
Best showing the sound
the Spectrum capture really is telling on seeing which whistle is a good design versus which whistle is a very poor design!
Do these sound different once they have been in water?
Greetings Audrey
I will address your question from several different perspectives.
1. the sound of any device in air is different than its sound underwater, this difference is due to several key attributes of water in general the uncompressed nature of water and the hydrodynamic pressure of water depending on depth, and the speed of sound in water which is roughly 1,500m/sec versus speed of sound in air of 345m/sec
2. the sound of any whistle blown underwater would return to it's natural sound in air as long as the Helmholtz resonant chamber is clear of any water or obstructions.
A quick note: some whistles such as common police style or sports whistles or the Storm have a modulation pea contained within and they generally will take longer to get all the water out of the Helmholtz chamber so that it will produce the normal whistle sound while blowing it in air again.
Hope this answered your question
Not underwater…. But when wet. I know the hyper whistle hardly makes a sound when it’s been dipped in water or wet in heavy blowing rain--personal experience made me throw that away and get a different one. It didn’t perform in a real emergency.
So when looking for a whistle where i need to focus is on the HZ?
Greetings Ramiro thanks for your question.
For longest possible usable range there are two contributing components SPL (loudness) and the center frequency (HZ) of the whistle.
ALL WHISTLES are omnidirectional (produce sound every direction) this is due in part to the size of the acoustic aperture (fractions of an inch) as compared to it's frequency of operation or wavelength of sound (3-16 inches depending on frequency) produced. this directionality attribute is called it's K-factor. and I don't care what the shape or length or diameter or any other BS claim, they are ALL omnidirectional with a polar response curve.
Unless the whistle is massive (more than 1 foot x 1 foot in it's dimensions) the wavelengths of sound they produce are longer than the aperture producing the sound (fractions of an inch) so the sound is and will forever be omni-directional.
Now that I have exited my directional sound rant if you compare two identical whistles in spl and one is tuned to lower frequency than the other, then the lower frequency unit will be heard to a further distance since the air damping function (absorption of the sound by the air) is less for the lower frequency unit allowing it's sound to travel further before it is attenuated below the ambient noise level of the environment of the sound.
At very low frequency sound is significantly less attenuated and so it is possible a lower tuned unit of lower spl can outperform a louder but higher frequency design.
Apples to apples comparisons will always require both the SPL and the center frequency to determine which whistle can be heard the furthest distance away.
Higher (Shrill) frequencies of the common sports whistle Variety are usually in the 4-5Khz realm which is a HUGE loss at distance when compared against devices in the 2-3Khz realm for instance.
If you want the longest range device? pick the one with the loudest and lowest frequency possible. but bear in mind it takes more air volume to produce lower frequency so a high pitched whistle may be easy to blow but the cost is it's usable range of the alert tone produced.
Hope this helps....
Curt
@@curtgraber Tank you! This helps a LOT!
@@curtgraber Hearing loudness is not linear for the ear since the ear perceives particular frequencies louder than others with sound pressure being constant(correct?). I believe the best way to measure is in phons the loudness of frequencies for hearing. I suppose some whistles may sound louder to the ear with near equal sound pressure levels if central frequencies are quite different. I figure since lower frequencies travel further what the whistle is to be used for matters as well. A whistle to alert a distress(long distance) or a whistle to disturb an attacker(close range).
I wonder if the bear whistle would really work, I wouldn't want to test it though for fun
@@vanillaexplosion99 I don't totally disagree with your position, however in working in the Acoustics industry for nearly 35 years now, I just use the old standards that OSHA and the entire industry still call Law, while one could argue new methodologies are better, it would likely result in almost identical results, example as in: CIS versus STI-PA and actual measured old school STI intelligibility scores. if you do the same tests with all three methodologies you result in almost identical number results...
How about niyet whistle? Issit true what they claim it's 150 decibel?
Greetings Tom
While we have not tested that particular double barrel whistle, I can tell you no double barrel whistle or even triple barrel whistle is even close to the claims as is pretty typical of china engineered/manufactured and marketed products.
Look at the Noopel, Viriber or Binbol they are exactly the same whistle as the Niyet and they also inappropriately claimed 150db and they always test under 120db they are just generally poor whistle designs but they are very cheap to manufacture (less than $0.25 USD per whistle in volume on the wholesale market look them up on Alibaba) so the market is flush with them.
Our test results in this video are now internationally acclaimed, we may repeat the effort in 2023 to include any new offerings, but so far just a couple of newcomers to the market and we have tested them, nothing improves on the top 10 of this list!
Can somebody please list which whistle was the loudest? I didn't have enough time to watch the whole video.
Shows it at 0:35
HyperWhistle is the Loudest whistle tested in this group by quite a large margin...
I have an old Brass ACME Thunderer and I am pretty sure it's even louder than the newer model here, it's so loud that everyone around said that their vision got blurry for the duration of the whistle. 😵💫
ACME thunderer whistles literally have not changed since inception , so I would guess your older model is identical to the performance of the current ACME model product
Me at 10pm listing to se which one is best for my mom and cousin 😂😂😂.
So which one is the best?

The Acme Tornado 635, even if not louder than Fox 40 Sonik Blast and the Tornado 2000 sounds more sustained and lower pitched, I wonder if it is better for longer distances and in the ocean.
Greetings Stefano
love the Acme stuff and you are correct the lower pitch will generally trump higher output for very long range audibility of any alerting device.
Duration of the blow is less important and in fact was proven to be almost not important, the most noticed signal is not a long loud continuous blast but a short beep, beep, beep repeated loud pulsing in recent Gov testing.
Cheers
@@curtgraber thank you so much. I go spearfishing, shore dives, with a dive flag, so i want to be heard by the occasional careless boater. It seems the Fox works less well than the Storm if wet or from the water, but it is bigger. The Fox sounds like any lifeguard whistle, so i am not sure if people pay attention to it. I have teh windstorm, only con is that it is larger than Fox and Acme.
I've carried a Storm whistle for probably over 20 years, and I'm glad to see it is the second-loudest whistle in this test, and actually sounds "like a whistle" to me in comparison to many of the others. But that relative new-comer, the HyperWhistle is very impressive, and according to the dimensions given, is actually of less bulk than the quite sizeable Storm, so I think I'm going to upgrade.
@@indigocrystalknight8864 do it means that it is wrong to extrapolate 1 meter measurements to 1000 meters?
@@sdjhgfkshfswdfhskljh3360 With sound waves, there is the INVERSE SQUARE LAW, where the loudness of a WHISTLE diminishes it loudness level, the farther away its sound waves travels through the atmosphere, according to a mathematical formula. The 130 - 140 DB LOUDNDESS rating is only good at about 10 - 20 FT. At 1 METER the sound level would be extremely loud, but at 1000 METERS it would be way less loud. At 10,000 meters, you could barely hear it, or not hear it at all. The STORM and HYPER WHISTLES are for EMERGENCY SIGNALING use, usually in MARITIME uses on LAKES and in FORESTED AREAS (if you're lost). I live in MICHIGAN and we have the GREAT LAKES and 11,000 INLAND LAKES, plus a lot of HEAVILY FORESTED AREAS, so SIGNAL WHISTLES are a good thing to have in MICHIGAN.
correct all devices tested follow common 20/log or Inverse square spherical expansion losses models where every time you double the distance from the device to a target it loses 6db or more. in fact it is usually greater then 20/log as the air also has a damping function that is also added in that contributes to the loses and this is why at very long range, lower frequency devices prevail or higher frequency devices... thanks for your input!
Who tf is going to blow that huge ass whistle? Bigfoot?😂😂😂
Loved your comment, and have used it in conversation a few times already! maybe Chewbacca needs a huge yellow whistle hung on his laser blaster belt ; )
were is the pealess fox 40 whistle
Many of the Fox 40 whistles were tested and performed quite well.
Found an orange windstorm at a dock whilst preparing for an ocean kayaking expedition, presumably fell off of a mariners lanyard, as the cord is broken.
I complete your thousand like on this video love this video
I appreciate that!
Claimed 180db LMAO. A flash bang peaks at around 170-172db.
yes virtually all of the Chinese made twin tube whistles are WAY OVER RATED! claims 180db produces 110db etc. there is no teeth in the market except customers returns so send them back if they don't perform!
I'm actually looking for a whole for a skating rink. I bought an electric one and it is way too loud. Claimed 120-150. 😖
thanks for you comment, in our testing we covered several of the electronic whistles and found that none of them meet in actual testing with performance claims of the packaged manufacturer claims. And I can 100% tell you it would take a car battery to hit 150db! that level will never come from a 9v or AA batteries it is just beyond physics due to the actual power needed to generate that level of acoustic output.
I think of the boss of the "Storm whistle" who keeps repeating in several videos that his whistle is the most powerful in the world, constantly comparing it with the "HyperWhistle" which is ultimately THE most powerful whistle in the world. The numbers speak, the “Storm” is crushed, with 14dB more! Just huge !
But we don't take into account the ease of use of "WindStorm" which can whistle in water, nor the price of "HyperWhistle" which is far too expensive and bulky.
For me the best size/power/price ratio are the Fox 40s, in particular the "Micro" and the "Sonik Blast CMG" used by referees of several outdoor sports. It’s a safe bet!
When the figures announced by the brand are lower than reality, it is a very good sign. On the other hand, the opposite, distrust.
I have the "EGWT Triple Tube" indicated for 180dB XD. It's a nice whistle that makes a lot of noise although in reality, it rings in the ears, it's not so bad, bought for only €2.
Very surprised by the "BinBoll Double Tube" which looks like nothing, among the smallest whistle in this video, but which sends very loudly! A very low price in China.
The “Nitecore NWS10” is also ultra compact, but above all made of titanium. A pretty good score compared to the size. 3dB less, but durable high quality product. An affordable price, even if for a few grams of titanium, it's still too much.
Greetings
Thanks for your input!
The numbers do speak very clearly on the results, however most of the products tested seriously overclaim their Output Level/Ranges especially the cheaper products from China which in general are just garbage products sold cheap.
lots of good products on the market but you get what you pay for.
the top products in performance generally cost the most as a premium offering.
Cheers

ASTM decibels to be measured at 15 ft
Not True, Literally the entire acoustic industry test is 1m and 1m is the test distance we selected...
3:39 This type is heard in a lot of old cartoons
So who won the Top 5
1. HyperWhistle 2. Storm 3. Valkeen 4. Windstorm 5. Acme Thunderer
I didn’t see Molten Blazza whistle anywhere😢
Sorry we could not have everyone's whistles on this test, but we did our best to include all of the market leading products and a few fun additions including the Giant yellow whistle :) I will add the Molten Blazza to our list of contenders for the next video.
I love sonik blast
It was number #13 in the list
Thanks for testing these, I am looking for a rape whistle and I wanted to get a super loud one.
Plenty of Loud whistles in this test result pick your preferred whistle
Greetings All
Per many requests... Here is a quick link www.wattre.com/supporting-document-whistle-test to a copy of the spreadsheet to make it easier to see all the details.
Thank you but that's not a "copy" of the spreadsheet. That's a "screenshot" of the spreadsheet. Is there any way you can post the actual xls or csv file? Thanks again for this test though. Great data.
It's still not that great of a resolution trying to load on my phone. Thank you for taking the time to do all this. I'm looking for a survival whistle for my gear bag and am trying to compare the hyper whistle and the storm whistle.
the 780tm whistle sounds like a goat screaming
Wow great testing method
7:40 - I have the STORM. The most impressive about it is not just that it's very loud, but needs NO EFFORT to blow! The only thing I don't like is how bulky it is...
The Storm is a great whistle and has been on the market for some time but it certainly is not the world's loudest whistle on the market anymore. Hyperwhistle is clearly louder and has a longer range as was shown in the video.
So what's the best
0:50 whistles
9:15 electric whistles
9:48 air horns
10:56 worlds loudest whistles
11:17 test results
Help for anyone here a the time stamps
If you are looking for a compact whistle, check out my overview of the ACME Slimline Tornado whistle.
Faltou o hiper Whistle que parece ser o mais caro de todos
Greetings HyperWhistle is not only included in this test but it is in fact the loudest whistle tested...
My tinitis is back.

7:28 was was that? an owl?!?
Good acoustic perception, it does sound like an owl and is also very close to the same spectral content and harmonics.
It was purchased from Amazon as a novelty "GIANT party whistle"
We had never had a mouth blown whistle that had a center frequency that low in the spectrum and it actually performs well over long range due to the lower frequency content as compared to louder but higher frequency whistles.
Good Fun...
Acme Thunderer every time.
I Appreciate your input, the Acme Thunderer has been a great whistle for a very long time, it placed 5# in the test for output and useful range...
My Favourites:
Nitecore: 2:20
Hyper Whistle: 10:55
We liked many of the whistles on the test, the Nightcore was certainly one of the favorites due to it's size and titanium construction, although it didn't score very high on the long range performance tests.
HyperWhistle was scored the longest range with a usable range of more than 2x every other whistle tested, although it needs a huge lungful breath to really get it to maximum output.
It is expected that the whistle that creates the loudest possible sound will require more pressure and more flow to attain the performance.
The engine of every whistle is literally the blower, and not the whistle, the whistle simply converts the positive pressure flow of a blowers lungs into an oscillation of pressure making a sound, if the whistle is designed right it can convert and use all the potential energy of the whistle blower's capable lungs, many whistles are poorly designed and can't accept the maximum pressure and flow of a healthy adult blower so those whistles were poorer performing as compared to others that literally could not be made to overblow no matter how hard we blew.
Hope this helps...
@@curtgraber
Wow! I appreciate all the information. Your insights and dedication to your work is quite commendable. It's quite evident that you love your work.
Good for you mate and Good job! ☺️💌
2.43 you covered one of the holes… re blow that whistle…
Sorry, it was not covered...
@@curtgraber it was I know how those sound and the pitch isn’t the same and it doesn’t sound like all three…
Where is molten b and dolphine pro
Greetings
We plan to do an update with any relevant new entries in 2022, stay tuned...
Cheers
Storms is best but i hate how bulky it is
Jay I appreciate your input but it is pretty clear that Storm is not the best based upon the scientific data and performance stack up, in fact the HyperWhistle has more than twice the usable range of Storm!
Well I guess the hyperwhistle is louder than the storm whistle
And it is by quite a large margin!
Molto strano nella realtà il sonic blast e molto più forte degli altri fox 40 e anche molto più forte di come si sente in questo video. Sono un arbitro e ci sono molte prove.mah
Pretty hard to argue with the actual captured test data both in SPL and acoustic spectrum of the whistles, often times the subjectivity of each persons ears can tell them that one is louder than another due in part to a specific whistles harmonic content, some harmonics are perceived smoothing (even order Harmonics such as 2nd 4th 6th Etc.) and (Odd order harmonics 3rd 5th 7th Etc.) are sour notes or harsh sounding to our ears. BTW that is also why tube electronics (producing only Even order Harmonics) are preferred for pleasing Guitar distortion in music as compared to amplifier clipping distortion (always odd order harmonics) and hard on the ears.
We have done a ton of tone work in this area in the past 25 years figuring out what people like to hear versus explicitly what they exactly don't want to hear for example.
