Fear of noises... Shelving filters are named to remind audio technologists that most people fear the ocean, i.e., the following picture.
The little it is worth; but note that a summer day spent on the continental shelf is scarier than just about every sound producible by humans. I myself would not have guessed this to be the reason - fear and prayers against devils and demons make up a great deal of the superfluity that is coined into terminology.
