I was reading an article on Acoustic Levitation http://science.howstuffworks.com/aco...evitation2.htm
and near the end it said
This got me thinking about the character Banshee from X-Men
Who's power, as described by the X-Men wikia is
Now I understand that this is not the same thing as levitation but I was wondering if it was still possible. Assuming that a man does have the physical ability to produce such powerful sounds without injury and with the assistance of a glider suit, could flight be sustained? He is 5'9" (175.26cm) and 170lbs (77.1107kg). Which aspect would be more important to his flight: decibel level or frequency? Would frequency be higher or lower for faster flight at high altitudes? Also if a person was falling from directly above him would his sound be able to slow them down or even stop them without causing them physical harm? What if it was an inanimate object and its well-being did not need to be protected? What level sound would need to be produced in this situation?
I know I'm asking a lot of questions so I don't expect all of them to be answered but it's just something I've been wondering for a while now. Also if you could tell me how you got to your answers that would be great. Thanks!
