Traditional experiments on sound waves in a vacuum have suggested that sound waves do not travel. Howvever, since pressure waves cannot propagate from a low pressure area to a higher pressure area, would it not be possible that we are just unable to register anything, being on the outside the vacuum? I would also like to know if any experiments have studied the ultrasonic waves in vacuum. Etienne Szekely
