Whistles:
A Quick Tutorial
A whistle is a small, light, inexpensive, tool that could save your life. Many survival experts consider Signaling a primary function in all survival kits, and the whistle is a key component. If you were lost in the woods, or God forbid, trapped in a collapsed building or overturned car, a whistle could definitely save your life.
Most of us cannot yell and produce a sound as loud as a whistle, at least not for very long. The average shouting sound by humans is around 90 decibels. You can get a whistle that easily produces over 120 decibels with very little effort exerted. By comparison a gunshot generates a sound in the 140 decibel range.
Construction
Most of the whistles on the market are made of metal or plastic. Some have a pea or similar round object to help generate the sound. Some are called "pealess". They generate sound without a pea. While most people would consider the metal whistle more durable, it is also harder to blow, and if you lose the pea it is useless. Metal can also be prone to rust or corrosion. If you have a metal whistle I would highly recommend getting a mouthguard to put over it. This is a rubberized shell that will encase the whistle, and save your teeth. More on that later. The plastic models are just as durable and offer far more variations of the pealess variety.
Most models will have a ring or some aperture made to attach a lanyard. I would highly recommend getting lanyard, and when you are using the whistle, keep the lanyard around your neck.
There are electronic whistles avaailable that came into vogue during the pandemic. They are not nearly as loud; they require batteries; and are considerably more expensive. I would not recommend them.
Use
Do you know how to blow a whistle? Seems like a silly question, right? You put it in your mouth and blow. Next time you see someone blowing a whistle on televison pay attention. Almost certainly, they will be holding the whistle in their lips, and their cheeks will be puffed up like a balloon. Go ahead and try that, and see how long you last. Your lips and cheeks will be worn out after five minutes.
To blow a whistle properly, you hold it in your teeth. This also gives the plastic models a huge advantage. Holding a metal whistle in your teeth is very uncomfortable. The metal has no give. The plastic will give and over time and continued use will mold to your teeth. Put your tongue over the opening, and blow with short bursts by removing and replacing your tongue. I believe if you are studying music they call this tongue blowing. You insert your tongue to regulate airflow. On a much more base level it is also the technique you use when you spit. I recommended earlier that you get a lanyard for the whistle, and when you use it, keep the lanyard around your neck. If you drop the whistle while you are using it you may never find it again. The use of a lanyard is self explanatory.
There is a universal code that three blasts from a whistle is a distress signal. Ideally, if someone hears your distress calls then they would respond with two whistle blasts. You would repeat each other’s calls until you are found.
Recommendations
We are not talking about a high tech piece of equipment here, so nithing is going to break the bank. Virtually everything is going to be in the $5.00 - $10.00 range unless you get something electronic. The electronic models will be in the $15.00 - $30.00 range.
My personal recommendation would be the Fox 40 Classic. This is a plastic, pealess whistle that comes in a variety of colors. It is available at a myriad of retail outlests including Wal Mart and Amazon
