Mysterious New Humpback Whale "Song" Detected?
Whale song recordings off Hawaii have revealed a strange series of deep beats almost inaudible to humans.
The latest release in the humpback whale’s haunting sound collection is a track so unusual that scientists hardly know what to make of it.
Unlike anything on the hit album Songs of the Humpback Whale (released in 1970, the wildlife recording went multi-platinum), the mysterious new noise has such a low beat it’s scarcely audible.
Near the lower limit of human hearing, the so-called “pulse trains" are deeper than any confirmed humpback vocalization, according to Jim Darling, a research biologist with the Whale Trust Maui in Hawaii.
It's “as if listening to a heartbeat with a stethoscope,” says Darling, whose study on the phenomenon was published November 5 in the Journal of the Acoustical Society of America.
