Here is a combination whistle/buckle - If you are concerned about weight,the unit weighs all of 0.35 oz. i purchased one and put it on my day pack - why not? http://www.rei.com/product/848923/gear-aid-whistle-sternum-strap-buckle-kit-34

Not actually all that loud, but it certainly is handy

I'm not a fan of lightweight at any cost. I like the Ti whistle because even though I "know" I'll never need it, it carries easy so I carry it regardless. That said, the Ti whistle is a back-up. The whistles I keep in my backpacks are Fox 40 Sharx. I like the form and they are plenty loud. At least for me, the Sharx blows much easier than the Fox 40 Micro. I'd like to try a Fox 40 Sonik Blast, but for now, the Sharx is what I have in my kits.

I chuckle when reading some of the postings in lightweight forums with their religious furor in "breaking the SUL barrier" and all that. I have never thought of myself as a "heavyweight" type, but utility and safety have always been concerns, along with weight.

I'm off topic again, but I don't want to start another whistle thread just yet...

I was curious about the deeper tone whistles because they consistently do better on carry distance. I just got an Acme 559. It's noticeably bigger and deeper toned than the Acme 560. However, the tone on the 559 is too deep for my taste. I'm satisfied that the Acme 560 is the sweet spot for pitch for me.

I also ordered the Acme 649 Survival Whistle. It fascinated me that the this whistle was the only whistle heard at 3/4 mile by a guy wearing a hearing aid. It even beat out the Storm for that guy.

I just got the ACR WW3 Whistle. I like the sound better than the Acme 636. It's also easier to blow as my 40-pound daughter verified.

The plastic is not quite as good as the Acme 636. I guess that's the reason for its low price.

The low pitched whistles do better for two reasons. First is age induced hearing loss starts with the higher frequencies, so older people will have a lower threshold for detecting low pitched whistles then high pitched whistles.

The second is acoustical absorption is an exponential function. Roughly put, every time the frequency doubles, the absorption into the air increases by a factor of 2.7. So, a 2 KHz marine whistle will have 2.7 times the sound pressure as a 4 KHz referee's whistle at a given distance with all else being equal. Wikipedia has an adequate explanation if you want the math.

Thanks for posting this. I thought it was just me.

I find that the lower pitch whistles cut through a lot more clutter and carry further. And it's not just my middle-aged ears: my hounds will hear a lower pitched whistle (like a Storm or even a flat 3-tone PFD whistle) in wind conditions or when bounding after a snowshoe hare. The higher pitched whistles like the classic Fox 40, loud though they are, don't carry.

Have you tried the Acme 559 or 558? They have a noticeably deeper tone than the Storm and don't hurt the ears up close at all. I have read they carry far, but I haven't tested them yet.
