Hypersonic Sound

From our talk with Prof Jer-Ming, he mentioned a cool technology that he couldn’t seem to name, but with the help of google, here it is, Hypersonic Sound!

This is basically the epitome of invisible sound, but since he introduced this in 2004, there has been companies that have picked up this ultrasound technology but have not been able to commercialise it. Makes you wonder how safe it really is!
