Am I missing something?
If recent press reports are to be believed the GSM Mosquito ultrasonic deterrent emits a noise that has been variously described as “shrill”, high-pitched” and “piercing”. How, exactly, is such a noise meant to DETER teenagers? Have the manufacturers of this device ever spent any time with teenagers? Because I would suggest that “shrill”, high-pitched” and “piercing” just about covers it, as far as noise goes. Surely a more effective deterrent would take the form of a recording of a middle-aged parent repeating something along the lines of:
“Look at the state of your room! You’re not going out dressed like that? You’ll eat it and be grateful, if you know what’s good for you. Are you on drugs? Can I smell cigarette smoke? Of course there was no internet nonsense in my young day. We had to make do with a frisbee and we were none the worse for it, I can tell you. Oh yes, amused ourselves we did …only three TV channels…half-day closing…power cuts…Bri-Nylon…Instant Whip… bring back National Service……Are you LISTENING to me?!
