Something amusing - Sonic Teenager Repellent

[N. A. Corbier]

This seems to be a high frequency sonic device, tested in England, that annoys teenagers so much that they will leave areas they usually "take over" and loiter around.

Anyone know about this, have experience with it, etc? A friend sent it to me as a comment on my personal livejournal.

Speaking of teenagers, anyone have a device that jams the signal from a car stereo to the speakers? (besides wire cutters )

You wanna repel teenaged loiterers? teenagers intent on doing ill deeds? Blast some loud country music, or classical music, or church music, over PA speakers. That'll get them running like cockroaches when the lights go on! LOL

Maybe once it is perfected they can come up with some adult sonic repellant.
I have seen some that make you want to stick an airhorn in their ear and not let up untill they leave.

teenage repellant

i have found the best way to repell teens is to get grandma and grandpa to start making out in front of them.This not only repells teens but makes them very ill also.

In a recent survey, I recommended the installation of low pressure sodium lights to discourage the gathering of teens. The human face and hands under LPS are grotesque in the extreme. They were installed, no more gathering of teens. Interesting point, the teens never complained, they got their burgers and fries and left.
Enjoy the day,

You know, people do look creepy under that unnatural pale... what is that? Pink? lighting.

We use the icky bluish-green sodiums here... And it works quite well... People tend to slink away from those areas... Somethin about those unnatural colors, I guess... lol

I like this idea. Opera would be another fine choice.

N.A., LPS characteristics in which virtually all the visible energy is emitted from the "D" lines double at 589 and 589.6 nanometers (yellow) near the peak of the visibility curve of the eye, monochromatic.
Safety markings, black and yellow jumb out at you when illuminated by LPS.
Enjoy the snowfall and the day,

Gentlemen: These is a security lighting term. A nanometer is a unit of measure equal to one billionth of a meter. So are lux, lumen, luminous intensity or candlepower and luminous flux. When we discuss visible light, which is very small part of the electromagnetic spectrum, wavelength is measured in nanometers.
These are the kinds of things we in this business need to know to insure we go home at night in the same physical condition as when we reported to our post or job.
When you are on post and you know in your heart of hearts the lighting stinks where you patrol either not enough or you instead of the perimeter is lighted, your very life may depend on adequate lighting of the proper kind and intensity. Lighting is just a tool like your radio, flashlight, baton, sidearm and chemical spray.
Your company may request the client conduct a lighting survey. If your company is worth its salt, a knowledgeable person will visit the site to observe what you observed and hopefully push the client into hiring a lighting consultant.
Various manufacturers publish lighting handbooks. ST&D from time to time publish articles written by lighting consultants.
I would encourage all of us to obtain a handbook from the company's library and read. Suggest you further purchase such a handbook to add to your personal security library.
Please remember, if we screw up, we may not go home at the end of the shift!
Enjoy the day,
Bill

Is there a formula for converting candlepower into lumens?
