Sound Wave Movers
Can you provide me with information on an individual, company or
organization that has researched, tested and proven the following can work?
Sound waves, (preferable a sign wave) produce motion in the air as they
move. I would like to know if any of the afore mentioned have proven
these waves can be a force to move an object. I'm not referring to the
movements of an object sitting atop a speaker. I want proof sound can
move something like a car or train.
There are many examples of sound moving other objects. An explosion is a
sound wave of sorts that can move large objects. A string which is the
appropriate length, diameter, material etc. can move in "resonance" with
another string being plucked.
Most musical instruments sound like they do because sound waves produced in
one part the instrument cause the motion of other parts of the instrument.
I do not know if anyone has been able to push a car with sound waves, but a
simple experiment is possible, light a match and hold it a couple of feet
from a sub-woofer and you would be able to see the fire move, thats proof
that sound can produce motion. The amount of energy you would need to push
a car with sound would probably be very great also you would also need an
extremely low wave, if anyone has done it it would be the military, I'm not
sure if they can push things with sound waves but they can destroy things
