What? I can’t hear you. My ears are still ringing.
I’ve had the original Fox 40 classic previously and loved it. I was hesitant to order the sonic blast because as a whistle purist, I love the high shreek of the original whistle. Well, some how they engineered this whistle to have dual chambers; one on top, one on the bottom that are identical to each other causing the sound to be amplified. Literally the same sound as the original fox 40 classic, just twice as loud. I know- it’s hard to imagine that any whistle can be louder than the original fox 40, but this is. I use this for traffic control on major highways and it’s legit. I have to honestly contemplate blowing it every time because there’s no way to blow it without having your ears ring kinda loud. The best solution is to cup your hands around it when you blow to offer the sound waves some guidance in order to not make my ears ring. But if you’re into that kinda thing, go for it. Seriously: I 100% recommend this for anyone who needs an immediate attention getter. Probably not good for indoor use in a gym- it’s really that loud.

Great thing is that you don't have to go full-force ...
Very loud, ear-splittingly loud if you really blast it. Great thing is that you don't have to go full-force to get a sound, it will whistle lightly if you blow lightly, and whistle big if you blow big. I'm kind of afraid to give it all I've got without ear protection. I got orange for visibility, it's going on my kayak life jacket for emergencies. Mine came with a black lanyard that's adjustable and break-away. I like the tooth guard, it's a smart touch. I compared it against the Storm, read lots of reviews and articles. This one has no bead, so the sound doesn't "wobble" as much as the Storm, but it's much more compact and approximately the same decibel level. I read that it even works submerged in water, but I don't know how well in a real world situation. I figure that with space being at a premium, this one has the advantage over the Storm (and anything else on the market) as it's just as capable and very shrill, but super portable.

VERY loud - perfect as a signal/survival tool
I purchased this whistle as a signal/survival item based on the description. It arrived quickly and I was able to test it out with the following results: Pros: - I like the high vis orange color. Makes it easy to find and helps with your own visibility. - VERY loud and piercing sound - is it as loud as advertised? I don't have a decibel checker, so I don't know. - No pea - means no freezing up. cons: - It does take a fair amount of 'wind' to get max effect. However, unlike some have reported, I don't find the effort to be extreme. Overall I find it to be perfectly suited to the task. Hope that helps.

Whistle is fantastic but I'm deducting a start because it's is un-safely loud
This whistle is actually really good and absurdly loud if you blow hard enough... So loud to the point I feel it may be unsafe for my hearing, I feel as though there should be a limit to the max db it can produce from a blow but it just gets louder ... So if you want ear drum blasting loud look no further but be cautious it's truly loud even for me using it out in the open

best whistle ever
this is the best whistle ever. i am a lifeguard and the whistle i had was not cutting it for me, my boss recommended the sonic blast so i decided i'd get it and try it out. buying this whistle was one of my best decisions ever. it is very loud, you will be heard over large cowards with ease. it doesn't take much effort to get a really loud sound. it looks very good and it makes an incredibly loud sound. this whistle is amazing. sadly though i had to retire my sonic blast because i was starting to get hearing damage in my left ear. there is not a whistle i would recommend more than the sonic blast, it is an amazing whistle from an amazing company.

If you get lost, you'll be found if you stay put and blow this thing
Loud to the point of pain, and beyond. I stupidly tried out inside, and think I blew out my ear drums. Holy heck! These are perfect additions to a prep kit to carry when leaving the beaten path. If you get lost, you'll be found if you stay put and blow this thing if anyone is within a mile or three (distances for illustrative purpose only; not a real measurement of how far the sound will carry)

Best choice of officiating whistles!
Fox40 Sonik Blast has been my go to whistle for almost my entire officiating (soccer) career. It’s incredibly loud and piercing, but super easy to control both your volume and inflections. It also doesn’t take as much air to get a lot of volume compared to other whistles also. I’ve tried various other whistles, but always find myself coming back to the this whistle. In fact, over time because of their affordability I’ve collected many of the colors to match whichever color uniform I’m wearing for a match or in the case of the pink whistles, support breast cancer research.

Works great!
Very loud! It gets my dog’s attention from very far off. I’ve seen reviews that say it does work - it does, but you can’t just blow weakly into the end of the mouthpiece. You need to get a grip with your teeth or lips and apply a bit of pressure when you blow. It leaves my ears ringing!

Great product
I purchased two of these and we both are quite happy with them. They are loud and easy to put on as the two sides of string snap together! I hope this works for our coyote problem and at the very least it will also scare an attacker.
