The "inventors" of the Fox-40 certainly got a lot of press when they convinced the local media that it was a new thing. However, the principle, several sound generators of slightly different pitch interacting and creating beat frequencies, is old and well known. There's a new version of the Storm whistle that's quite loud and may or may not have a pea in it - I'm trying to find out for sure. The packaged versions rattle, but it isn't clear that a pea is responsible.
