Whistlemania IV – Sound Off…

Image

Whistlemania is back!! This week we broke out the sound meter to see how loud our whistlers could get.

Let me first say that measuring decibels is just one more variable to consider and a loud rating on the sound meter may, or may not, correlate with the distance heard on the ground. Nevertheless, decibel ratings are often used as a marketing tactic by whistle manufacturers.

For the testing I used an Extech SL10 Personal Sound Meter, my lungs, and the lungs of Jake, a 9 year old, athletic boy weighing 67 pounds.

Forty five years ago, on this very weekend, a six year old boy went missing in the Smokies and was never seen again. This tragic story and lessons from the huge search effort helped to shape the search and rescue techniques and protocols of today. A whistle is one of the best items to equip your kids with in the woods, so it makes sense to see which whistles work well for them.

The Dennis Martin story: http://www.knoxnews.com/news/2009/jun/28/missing-dennis-martin/

Thanks to my pint size partner, we can also extrapolate the effectiveness of each whistle for an adult with a chest injury or condition preventing the full use of the lungs. Last year, I was routed to respond to a hiker that had been pinned under a tree for a day, after a tornado rolled through the park. http://www.local8now.com/news/headlines/Rescuers-work-to-save-53-year-old-hiker-trapped-by-tree-211582431.html. I never made it there, getting redirected to another emergency, but that scenario could easily crush ribs or restrict your lung capacity. Furthermore, COPD, asthma, and a host of other lung ailments restrict the breathing ability of millions each day, so value may be found for them as well.

I asked Dr. “Hunk” Miller the ins and outs of lung volumes and this is my lay person understanding. If one were to blow on a whistle, you would use both your Tidal Volume (TV) and your Expiratory Reserve Volume (ERV), which equals out to be 22 ml/kg.

Image

Jake, weighing in at 30.5 kg, has around 670 ml of potential air to blow his whistle. That would be the equivalent of a 135 pound person with only one lung or with a chest compressed so it cannot fully expand. If you weigh 135 pounds or more, one could assume that a good performing whistle for Jake would function equally as well if you had an injury that restricted your lung volume or a chronic breathing problem.

This is all important if you consider that if you are using your whistle, there is a high chance that your are injured and/or under the effects of adrenaline, potentially affecting your breathing rate and capacity.

Here were the testing parameters:

1. Decibel level measured at the meter. I assumed, and testing supports, that manufacturer’s claims are done at this distance

2. Decibel level at a distance of 4 feet by a 200 pound adult. Notes on how hard or easy to blow each whistle are in parentheses. Resistance seemed to be the determining factor and can been seen in the duration of the whistle blast in seconds. “Hard”, in this context, means that the whistle provides an amount of resistance greater than the other two categories and does not connote difficultly in use.

3. Decibel level at distance of 4 feet by 67 pound boy. Notes on how hard or easy to blow each whistle are in parentheses based upon Jake’s opinion.

I chose 4 feet for tests 2 & 3 because two other field whistle tests were done at this distance and following that standard will allow comparison.

BigPig Outdoors Ear Ringing, Spit Flying Observations:

1. Most of Jake’s scores were very close to mine, a few higher, and some a bit lower. This suggests that lung volume to achieve a loud whistle blast is not much of a factor. Jake outperformed me on several whistles and in one of the linked studies, the child routinely got higher scores.

2. I am not a fan of the “Too easy” to blow whistles. The largest difference between Jake and my scores were seen with these and a few of the windier “easy” whistles. A little resistance by design or by a pea, allowed a more efficient use of the expelled breath in my opinion.

3. Some whistles require perfect alignment or placement of lips that could prove challenging under stress or while injured. These whistles were also tough for Jake to manipulate, and would therefore be poor choices for little ones.

4. The decibel scale is logarithmic, so my lay person understanding is that a 10 dB gain doubles the loudness. In perceived loudness, the 5 – 10 decibels can make a big difference. Source: http://www.sengpielaudio.com/calculator-levelchange.htm

5. Like I stated earlier, I think decibel ratings are not as important as the distance that a whistle can be heard, which is a factor of loudness, terrain, and frequency.

Stayed tuned as Whistlemania hits the woods and lakes to see how the whistlers perform at distance…

Whistlemania I – Weigh Ins…

Image

What in the hell is Whistlemania? Well, it is the Battle Royal of 30 of the world’s toughest whistles. Back in 1986 at Wrestlemania II, twenty of the world’s strongest, fake wrestlers and NFL players fought it out in a ring to a scripted battle leaving Andre the Giant as winner.

Unlike professional wrestling, Whistlemania pulls no punches, has no script, and no Pay Per View fee!!

Before you sound off the nerd alert, let me give you the two-fold back story. First I was looking for a good whistle for my future online store and kids classes, and only the best will do.

Second, my good friend was looking for an emergency whistle for his kids, so he said..

“What be-eth the best whistle good sir?”

I replied.. “I do not knoweth Sir Coop, but I will find out in short order”

Spurred by noble goals and “Over-The-Top” syndrome, I tapped into my twelve year old, Wrestlemania-watching forebrain to create a 7 part whistle torture test. That’s right, tune into to future posts to watch the drama, and truth, unfold.

Yeah, maybe whistles aren’t as cool as AR’s, flashlights, and knives, but one of the most rewarding moments in my career was watching a family be reunited after Rambo Ricky and I found the lost grandparents using whistle blasts in dense vegetation. Whistles work when your voice gives out. They are lightweight, inexpensive, and essential. Whistles save lives.

Want to spend a lifetime wallowing in anguish and regret? Don’t spend $5 on a whistle for your kids and you may get to if they wander off in the woods.

Whistles aren’t just for kids though. Try yelling for help repeatedly and you will soon find out that your voice will give out and you will wish you had a whistle. I carry one every time I hit the woods and usually have a backup version on my sternum strap or neck lanyard.

So what is the best whistle? If you said the one you have on you, you are right. Carrying any whistle is better than not, but hopefully this series will sort through the myriad of choices if you are hunting for a new one.

“Whistlemania 1″ will focus on the size, weight, cost, ruggedness, and my general impressions. I only measure length and width on whistles that were slimmer than 1/4” and did not test the expensive titanium whistles because they cost too much for your average woods trekker. There are some other good whistle reviews, and I will link them at the end of the series for inquiring minds.

I figured the worst thing that could happen to a whistle in the woods is get stepped on, so the “ruggedness” test consisted of my boot crushing the whistle with all 200 pounds of pressure on a hard surface. 28 out of 30 survived this test and I will showcase those failures at end of this post.

Image

Enough talk, time for the show. The contestants are ready for weigh ins, so let’s see the divisions and meet the gladiators..

Image

When I think of “Lightweights”, I think of whistles that I wouldn’t mind having hang around my neck. These would also be the class for smaller PSK’s, Personal Survival Kits., that you carry in a cargo pocket. Weight wise, they all weighed in under .30 ounces.

Jetscream Micro – Ultimate Survival Technologies. Around $3. Really small. Pealess.

Image

ACME Thunderer 660 – About $6. Has a pea. Has been on my SAR chest pouch for years.

Image

Fox 40 Classic –  $6. Pealess. Keels on bottom can be shaved off to give a flatter profile.

Image

ACME Tornado 635 – $7. Pealess. Non-traditional design.

Image

Hammerhead – $4. Has a pea. Unique design projects sound forward. Specialized pea claims to prevent freezing.

Image

Tin Whistle – Free. I was first shown how to make these by Mors Kochanski using aluminum flashing. This one was from a can of Rotel and you can also make it from a coke can. I will blog how to do it at the end of this series. I included this one because I have seen people use it for their primary whistle.

Image

Fox 40 Mini – $6. Pealess. Smaller than the Classic. I shaved the keels off years ago and I don’t know what the melted goo on it is, maybe pine pitch. At least I hope so.

Image

AMK or SOL or Fox 40 Micro – Several names and costing about $8 for a 2-pack. Nice slim whistle.

Image

ACME Tornado 636 – $5. Pealess. Nice size and well built. S.O.L.A.S. approved

Image

SOL Slim Rescue Howler – $6 for 2. SOL rebrand of the ACR whistle, but tone is a little different. Flat and pealess. No tooth ridge.

Image

ACR – $5. Pealess. Dual tone. No tooth ridge. Flat. USCG/SOLAS approved

Image

 

Next up is the “Multi-purpose” division that boasts whistles as a side benefit or in conjunction with other tools.

Image

Coghlan’s 5 in 1 Survival Aid – $5. Has a pea. Whistle, compass, mirror, match case, and a ferro rod. I wouldn’t want to count on the ferro rod for a fire, but I did light a cotton ball with it.

Image

Zipper Pull Whistle – $5. Pealess. Replaces the zipper pull on your jacket.

Image

Coghlan’s 4 in 1 Whistle – $5. Pealess. Whistle, compass, magnifying glass, and thermometer. The magnifying glass is convex on one side and flat on the other. I am no physics geek, but I think that reduces performance. I did manage to light a fire with a piece of punk wood transferred to a tinder bundle.

Image

Sternum Strap Whistle – $5. Pealess. Replaces sternum strap buckle on your backpack. May require sewing to switch out.

Image

LMF Swedish Firesteel Army 2.0 – $19. Pealess. Scraper has a built in whistle. I carry this rod on my knife and the scraper on the neck lanyard. The whistle works, but has a sweet spot.

Image

 

The big boys are ready to rumble…

Image

Windstorm – $5. Smaller version of the famous Storm whistle. Has a pea.

Image

Hammerhead Mighty – $5. Larger version of Hammerhead. Has a “non-freezing” pea and unique design to project sound forward.

Image

 Lifejacket Whistle – $3. Belt clip on back. Pealess

Image

 FOX 40 Eclipse – $9. Updated version of the classic.

Image

 

 Storm – $6. Has a pea. Claimed to be the world’s loudest and to work underwater. Largest of the heavyweights. USCG/SOLAS approved

Image

Scotty Lifesaver – $8. Two peas and an anti-choking collar.

Image

ACME Tornado 2000 – $6. Pealess. Another claimed to be the world’s most powerful whistle.

Image

 FOX 40 Sonic Blast – $9. Pealess

Image

 UST Jetscream – $6. Pealess.

Image

 Whistles for Life – $5. Has a pea. Official whistle of NASAR. Very wide mouth piece. USCG/SOLAS approved

Image

Promo whistle –  $5. Get your logo printed on this one. Bass Pro, TOPS Knives, etc. Pealess

Image

 FOX 40 Sharx – $6. Pealess

Image

 ACME Cyclone 888 – $7. Pealess

Image

ACME 649 – $8. Pealess. SOLAS & NATO approved.

Image

 

The 2 whistles that failed the crush test were the ACME Tornado 635 and the Tin Whistle, no surprises there. The Tornado still worked after bending it back, but the plastic is obviously stressed and the tone may have changed. The Tin whistle worked after bending it back into shape as well.

Image

 

Place your bets ladies and gentlemen and tune in next week for Whistlemania II.
