How many of your are aware of what the sound is like? As the majority of the thread cant hear the sound I'm just wondering how they can judge on whether it should go or not? As far as I can see you have only been told its an 'irritant'.
As I have said already, I doubt there will be much use for them in Ossywood because our teens are too far evolved from Darwener's to stand around outside shops, they've got sense and hang around places they can sit.
I don't think its harmful to babies any more, I heard the sound this morning. I also don't think it will work as a deterrent to teenagers, I think it would be quite easy to get used to.
