Thank you for your support in trying to get legislation put in place to govern the use of my device The Mosquito.

Calling it a weapon is more than a little strong. Measuring sound levels is a lot more tricky than it would appear but here is a ruff guide.

Sound is generally measured in Decibels and a 6dB (decibel) increase equates to a doubling of the sound pressure level.

Usually a dB measurement is taken at a distance of 1 meter from the source of the sound. If you double the distance you half the volume.

As an example a petrol mower typically produces 105dB when measured at 1 meter. An alarm clock 80dB and traffic noise 80 to 90dB.

The Human ear is more or less sensitive to sound depending on the frequency of the sound with frequency in the range of 1000Hz (Hertz) to 8000Hz being the frequency range the ear is most sensitive to.

To take this into account, volume levels with regard human hearing are plotted on a graph that takes frequency into account, this frequency adjusted volume level is referred to as dBA.

Now onto The Mosquito, there are minimum of 4 volume levels that can be set by the user, these range from 105dB to 84dB measured at 1 meter.

The frequency that the Mosquito uses on it’s Teen setting is 16800-Hz and higher. When measured on a the dBA scale these frequencies are heard at a volume of 10dB lower than for example a vacuum cleaner.

So as to the maximum volume of the Mosquito compared to traffic noise on a busy road it is very similar when measured at 1 meter.

Question? How close is a child to a installed Mosquito. Answer. It is unlikely that any one would be within 2 meters of the device and a young child 3 meters. Remember when you double the distance you halve the volume.

Conclusion your child is more likely to damage their hearing using there MP3 player than being chained to a fence directly in front of a Mosquito!!!!

Putting all of the above aside The Mosquito was designed to combat anti social behaviour not to drive children away when used in a Public area.

Where there is no right of access for example a School after hours then a Mosquito I believe can be legitimately used. At one School Mosquitos reduced the cost of reparation of site vandalism by more £50,000 in the first year.

I have been informed that a single visit by the Police to a site costs between £200 to £300 a visit with many sites visited on a daily basis. This is our money that is being wasted on ASB.

Where my device is properly installed and used it has the potential of saving millions of pounds a year and can and has transformed the lives of people for the good.

But just like a badly driven car if used incorrectly The Mosquito can become a nuisance. This is why I have campaigned for legislation to cover the fair and correct use of my device, but to date to no avail.

I wish my invention was not needed but with sales of over 5000 units it obviously is!!!!!!!

If you can help me in my quest for regulation please do.

The noise is one I hear in a lot of places (if I remember rightly they have it installed in the London Underground and several subways in other places), not a nice one! It is very high pitch, and hurts! I am 16 so I presume I shall just have to cope with it for another 9 years!

The police have pepper spray and truncheons to help break up problems but they are used sparingly and not on everyone. It is the indiscriminate nature of this device that most bothers me. And I’m told by Howard Stapleton (the inventor) that he has designed an alternative that could be deployed only if needed. It would be done so by a legislated body (such as the police) rather than any shop person who wasn’t happy with a group of people standing outside his shop.

I agree with your rant (have you met my uncle, Roy The Artist? He wrote a whole ranting blog post on here ) and like Ben said in his post here, a lot of the problem is boredom. When we were children it was safe to play outside all day. My husband remembers going off for the day without is his mum knowing where he was going. It was just the done thing.

I’m not sure what the solution is to that but it certainly isn’t installing a device that effects the masses.

So I’m outraged at that side of the story. But I am totally amazed and in awe of a device that can emit a sound audible only to young people. Wow! That’s impressive, and I mean REALLY impressive… to the point of being unbelievable.

What can we do? Like you said, they’ve been around for four years now. Every year the debate starts again but to no avail.

I had an email back from Howard Stapleton this afternoon. He’s written to Alan Johnson and seems keen to see his devise used properly and fairly. He’s also keen to dialogue with Give A Brick. Not sure what else to do but feel that something should be done.

As for The Mosquito, that isn’t a photo of it. It’s just a funny looking snow sculpture I found. The real thing is a lot more boring looking. Will dig out a photo shortly.
