The whistle as a warning or deterrent has a long history. The ancient Chinese blew into the tops of acorns whenever the Mongol hordes were threatening to invade.
Much later, Joseph Hudson developed the pea-whistle that could be heard a mile away and he was soon awarded a contract with Scotland Yard to replace the rattles that the bobbies were using to call for backup.
Since then, the shrill sound of the whistle has been used worldwide both as an alert and as an attention garnering deterrent to those who would rather not be seen or heard.
The whistle immediately signals that something is amiss and those within range are likely to investigate or at least call authorities.
In his article, “Don’t Shout…Screech!” at USConcealedCarry.com, author Rick Sapp describes the effectiveness of owning a whistle as part of your home defense system:
“Screech on the whistle a few times and your neighbors will call the police even before they hear a gunshot. You won’t have to put the gun down to punch in 911. You blow and stay focused on remaining calm and observant.” (Read more at USConcealedCarry.com)
Carrying a whistle on your person should also be part of your personal defense plan. Of course it’s not a substitute for a handgun or knife, but it may be enough of a deterrent to keep you from having to use those weapons.
There are many testimonials from would-be victims who claim the loud noise from the whistle startled their attacker enough to force him to flee. A whistle is a weapon that can be used from a safe distance. This isn’t the case with a knife or pepper spray where the threat is immediate and potentially life-threatening.
A whistle also cannot be turned against its owner as other weapons can be. Although a gun can be used from a distance, opening fire on a perceived threat is never a good idea and will probably land you in court, or worse unless your target is actually shooting at you.
Do not be like the subject in Edvard Munch’s painting, depending on your voice to save you. No matter how haunting and shrill you may think it is, a high quality, high decibel whistle is always a better option.
