Maybe I'm the last person to hear about this, but I still thought that it was worth blogging about. This product is called The Mosquito. It's been reportedly deployed effectively in the UK to disperse unruly, loitering teenagers so now it's going to be making its debut here in the U.S. How does it work? I'm glad that you asked. Straight from the vendor's website; "The system generates a pulsed, near ultra sonic tone at around 16KHz, close to the limit of the hearing range of people under 25 years of age. The sound, though not painful in any way, becomes highly annoying after 5 or so minutes exposure. The result is that most under 20s leave the immediate area, whilst the majority of those over the age of 30, because of natural age related hearing loss, either just hear, or, as in most cases, are totally unaware of any noise.
The system is designed to be used for up to 20 minutes at a time. The unit incorporates a 20 minute cut-off time to avoid unnecessary annoyance."
Wow. I have a ton of concerns about this product, but I am actually very interested to see it working in action. Not on me of course, but on some other annoying person. That brings me to another question. What product exists to annoy people over 25?
