***Updated with decibel test***: Personal audio distress alarm

[pRICE cUBE]

6 pack for $21.99. https://www.amazon.com/KOSIN-Personal-Se...onal+alarm&qid=1582817488&sr=8-5

There are other similar deals and quantities on Amazon so take a look. I am not promoting any particular brand or seller. I listed the brand a colleague uses. Here are the others https://www.amazon.com/s?k=Personal+alarm&ref=nb_sb_noss_2




I was speaking to a colleague about news events, particularly stories about attacks from individuals, attempted abductions, etc. She pointed out to me that she keeps a keen awareness of her surrounding and people around her. She avoids being distracted by her phone when in public and transitional spaces. She also has this alarm, pictured above, that puts out a 140 decibel alarm when the pin is pulled. I asked to see how loud it was so she activated the alarm. It gave an ear splitting shrill noise. A person in the building 2 floors up told us later he heard the alarm.

I imagine this could be good for people looking to repel individuals with ill intent by attracting unwanted noise. It may not stop all people but is definitely louder and more prolonged than screaming for help. It is small enough to be on a backpack or bag. Could be a tad large for a keychain depending on your personal preference and how many other items are on there.


***Test Update***

I was able to test the device briefly.

Test conditions:
8x8 foot room room with 9 foot ceiling
Hardwood floor
Standard looking drywall
Various wooden furniture
Door closed
iPhone 6S Plus with app DB Meter (free version)
65F (storage room so it doesn't get heated well)
Device was shipped this week and flashlight mode not used.
Item placed in center of the room.

6-12 inches and edges of the room (4 feet) all recorded 120 decibels. It is not the 140 as advertised so below the 150db where hearing damage begins.

Other people in the building reported hearing it through the drywall and wooden door from 2 floors away.

How easy is it to do temporary or permanent hearing damage with such a device? I'm not speaking for or against this as a safety device, but it's not the sort of thing you'd want to leave where your toddler could reach it. Or your cranky tween. Or your angry spouse who gets tired of listening to you sometimes.

My understanding is the threshold of hearing damage begins around 150db. This device claims 140db. I did not use the decibel measuring device on my phone. It was on for about 5 seconds and I was standing at conversational distance. After it was deactivated, I did not having ringing or pain in my ear. I know that isn’t exactly scientific. I might see this person later today so I will try to ,ensure with the decibel meter if I get the chance.

I also pulled the pin and it takes a bit of little effort, it doesn’t just slip right out. To a toddler, the cord holding the pin would likely just look like wrist band.

great for teens to randomly toss into crowds!

fyi, each uses relatively cheap 3x AG13/LR44 button cell batteries.

Based on the reviewers' videos, it is loud!
Apparently the folks buying these devices also purchase Pepper Spray...

Pepper spray gel is good for a situation where the audible alarm doesn’t scare off an attacker and a self defender does not have the foot speed or ability (physically impaired) to run.

The Gel is a stream similar to a jet of slime that won’t blow back on you unless you are in super high winds. The older style sprays are much easier to affect the sprayer/self defender. Sabre Red Gel is the brand I use when I go on jogs. It is supposed to be effective on dogs as well. https://www.amazon.com/s?k=Pepper+spray+gel+Sabre+red&ref=nb_sb_noss_2


I personally use this one that come with a holster https://www.amazon.com/SABRE-Red-Pepper-...+Sabre+red&qid=1582824545&sr=8-7

That's good to know.

Manufacturers routinely play with dB ratings and there's basically no standard for measuring, nor are most manufacturers likely to explain how they made the measurements.

I think OC in liquid or gel (gel is a great idea) is superior in general, to a noise maker.

Predators are generally of two types – easily scared off and not.

Someone chosen as a victim won't have much time to chose the most appropriate deterrent at the time of an attack. And escape is the most important consideration for most people in most circumstances.

If the attacker is not scared off, elevating DefCon becomes problematic. I think OC should be the first line of defense.

A shriek alarm could be used to call for help if debilitated, if a phone is not present or for a more immediate response.

But the main problem with just about any alarm short of a fire alarm is that people tend to ignore them.

I would opt for OC spray gel as first line option as well. Attackers could have criminal bodily harm intent, mental derangement, or be under the influence of illegal drugs.

I would suggest using OC first to defend and then run if possible or fight and using the audio alarm to attract attention.
