Gianni,

There is concern that infrasound from ships may be disturbing the long
distance communications of whales across hundreds of miles of ocean. These=

low frequency sounds cannot be heard by the human ear, but are they not
still anthropophony?

BTW, I can hear down to around 5Hz. Does that make me a whale? :-)
