World's Biggest Referee Whistle Sound Test - Molten, Fox 40, Acme, HyperWhistle… dB Comparision

How to blow into a whistle:

This is the world's biggest whistle test video. It took several months of planning to get all these whistles and special permission to be in Gamla Ullevi in Gothenburg, Sweden.

While the loudest whistle doesn't necessarily mean the best, it's an important factor depending on the intended use. Practicality and sound consistency are also important to consider. In this video, I blew the whistles with full force to ensure fairness and I created a race chart to show how they compare in sound level.

Most whistle companies do not specify the distance or measurment type when stating the decibel levels of their whistles, resulting in a lack of standardized measurement practices. Some companies use A-weighting while others use C-weighting. I chose to measure the decibel levels from a distance of 0.5 meters with C-weighting. This decision was made considering that some companies measure from closer distances, while others choose 1-2 meters. C-weighting is particularly useful for measuring short bursts of sounds, such as whistle sounds.

The gauges were created with Microsoft Powerpoint.

Awesome experiment, thanks... I own a lot of these whistles, and the Acme 558 (1:15) remains my favorite. The lower frequency travels farther while not hurting the user's ears as much. The pea adds a desirable warble. Also, the Acme 558 is less than half the size of the Storm (3:55), another great pea whistle. By the way, I am not a ref, but I use whistles for outdoor activities, like snowboarding, camping, dog training, etc.

You've created some fine reference material here, thank you.

[danishfawaz]

The slimline tornado 636 is my go to. Its my edc whistle, vehicle emergency whistle, sports refereeing whistle, because its just so light and small yet packs a punch! And easy to blow

[JCupry]

I have to say compared to the last whistle comparison, a leap from 16 to 60 whistles is astounding! With so many choices available, it's safe to say this is truly the biggest whistle comparison yet. Very interesting to see that most Molten whistles are on the higher end of the dB scale. I might have to look into a new secondary whistle option! (Main being the Valkeen of course :D)

One thing I'd like to know is if you have done whistle signals from different positions (further away, while running, etc.) this time as well, and if so, can we expect another video with them included?

Anyway, great video and thank you again! Happy new year and good luck with the upcoming season/matches!

[aatinka_]

Great video, thank you! I enjoy using Sonic Blast, it is somewhat underrated whistle imo.

[leewoosuk]

The most valuable clip for the referees! Brilliant !!

[janmarkowicz]

Can you remember original Fox 40 Sonik, produced before ca. 2007? It was advertised as '4-chamber, Multi-directional Whistle' with exactly 125 dB sound power - the loudest in Fox 40 history. Later they re-designed it into Sonik Blast, which has 'only' 120 claimed. I strongly wonder how it sounded like. It's very rare today and hard to find.

[michalsima]

Hello, fellow referees, who also has the problem of ringing in his ears after the match (my whistles are acme tornado, fox40 clasik, molten, all around 120 decibels, but it still whistles in the ear, who and if he solved it somehow by changing the whistle, for example?

[chechu]

If you had to referee a Champions League match, what would you use from these 3? HRS, Acme Tornado 2000 or FOX 40 classic? I appreciate your answer

[AlifAlkahf]

Can you rank top 3 whistle that are good to use indoor?

[dickydakarosma]

The Dholpin Pro whistle that I use is bigger than the Molten Valken😂

[DUDU-mugr]

Você gosta do Fox 40 sharx é meu preferido saudações do Brasil

[octaviolopez]

I heard for the Valkeen there’s a secret way to use it I was gonna ask if you know it and if you do can you do a video on how to do it

[CaiPotter-pf]

valkeen is still my favourite, didn't know it was that loud though!

[BizarrePower]

Curious have any of these whistle companies ever asked you to do a video for them?

[hodu]

I have a few questions about the whistles in this video.

1. I thought the Dolfin Pro was for volleyball but you claimed as outdoor sports. Is it because it is one of the loudest whistles?

2. What is HRS? Is it ripoff of Valkeen or some other brand that became same design as Valkeen?

3. Can I use Valkeen in any sports?(Outdoor, Indoor, Futsal, etc) because I'm too lazy to having a other whistles for indoors.

Lastly I am glad that you are still here to make a whistle comparison. Happy new year!

[chucky]

There is a difference between what we hear and what the dBmeter gives as numbers.
Depending on the use, the frequencies are not the same, and for a less powerful whistle on the theory of numbers, it will be heard from further away with a frequency intended to be so.
If we do the ranking by closing our eyes, it will not be at all representative of the figures, that's for sure !

[ngoquanganhmurad]

Do you know where the Pro Match Unique horn is sold?

[TheClearLight]

Isn't storm the loudest whistle? I've heard its comparable to the sonik blast if not louder
