Some have natural explanations, others may be hoaxes. But they’ve driven a compelling story over the past year or so. Perhaps it’s just one of those 2012 doomsday things.
At any rate, another strange noise has popped up in West Seattle. Some residents believe it’s always been there — a low-grade hum that seems to rise and fall and sometimes vanish altogether. Others are fairly sure it’s a new phenomenon, describing it as “unworldly” or “creepy.”
One possible explanation given by scientists at the University of Washington is that the bizarre noise may be caused by male midshipman fish, which use a very “distinct mating call” that may become amplified by ship hulls. Recordings of the fish compared to video evidence of the strange noise apparently share a similarity.
Case closed, then?
