Being in self-defense industry, I am always in what works and what does not work when it comes to you and I am interested to protect ourselves from crime. Today we will talk about personal memories of what they are, what they are doing and are they really an effective form of defense against crime.
First, what they are. Your memories are typically make small, battery-powered devices that much noise. Their small size they can easily carry on your person to ensure that thename “Personal Alarm”. I know, I know, that sounds pretty obvious to most of us, but I had to start with a basic description just in case anyone out there is brand new to this sort of thing.
Next, what they do. Well, like I said, personal alarms make a lot of noise. That’s exactly what they’re supposed to do and as long as they’re working properly, that’s exactly what they do. The average personal alarm has a noise rating of anywhere between 100 decibels and 130 decibels. To share, consider this perspective,
· A home vacuum cleaner is about 65 decibels, according to 70
· An average alarm clock is about 80 decibels, according to
· A chainsaw is about 100 decibels loud
· A jackhammer is about 130 decibels loud
· And a pistol or an air raid sirens are somewhere around 140 decibels
Sounds louder than 90 decibels are considered potentially dangerous to a person belongs. Both the level of noise and theDuration of exposure determines the amount of damages.
Most personal alarms are caused either by a push button, a capitalized on / off switch or a pull-out pin that the alarm off when the pin removed from the device activated.
I personally prefer the ones with the pull-out pin, because if the alarm was killed in a fight, will not accidentally turn it on. In fact, the only way they shut down () to break into short pieces is the activation of the PIN or remove to replace theBatteries.
Finally, they are effective? Yes, they are effective, but it depends on what you expect them to do for you. Your memories work because they loud, high frequency, which emit far more irritating to the ears as a low frequency pitch of the same volume.
The screaming siren sounds or sometimes that these memories can be made quickly, an attacker for a few seconds to confuse, and they can also cause pain to the eardrum, even if the persongenerally not sensitive to loud noises.
But the meaningful use of these personal recollections, as I see it, their ability to draw attention to your situation. Most criminals do not want an audience when they attack someone, and a 130-decibel alarm can be heard as far away as two or three blocks, even with the sound of flowing traffic on the road. So they can easily have the attention of every nearby while you are walking across a parking lot or on the street,or even jogging through the park. This alone can often send your attacker is running in the opposite direction in search of quieter prey.
Your memories only cost a few dollars, which makes them very easy to own. Also, they are not weapons, so they are legal to carry everywhere. But please remember that like any self-defense tool, a personal alarm is not magic. No matter how loud your alarm, it will not protect you put up some kind of magical force field that youof all the bad people in the world. However, you will catch most people by surprise and confuse them long enough to escape you the opportunity. And they are also attention to your situation, even if you are not able to scream for help.
