The lost week or two there was a forum about what ultrasonic waves are can are audible to different people. Generally the younger you are the higher range of hearing you can hear. I down loaded some soundfiles as wringtones for my phone and tried them, it really annoyed some people, while older people could not hear them

Then I thought wouldn’t this be a wicked weapon, if I put this on my getto blaster, teens and dogs would fall off their mini motocycles :twisted: :jester:

But someone always gets there first so I typed Teens and Ultrasonic waves into google and found this. http://www.compoundsecurity.co.uk/deter ... ws_83.html

Maybe that ultrasonic noise can be used as a bully repellant.
