Sky noises reported in Seattle (Updated: Maybe not from the sky?)

The mysterious sky noises continue…

Strange hum keeping West Seattle awake | KING5.com Seattle.

Julie Schickling stood out on her porch in West Seattle just after midnight because she couldn’t explain what she was hearing. So she recorded the sound (listen here on West Seattle Blog).

“It gets high and lower, and goes away, then comes back,” said Schickling.

Some of her neighbors report being shaken out of bed by the low rumble, also described as a  growl. In fact, as many people you talk with is about how many different words you heard to describe it.

Tip: Fortean Times

Typically, these events are a result of local industrial noises but that has been denied in this case (it usually IS denied). The city is looking into pinpointing the noise.

The sound can be heard here. It is curious and not completely unlike those sky noises heard earlier this year all over the world. Some of them were hoaxed. There is not enough information here to say this is a hoax (it really appears to be genuine) or what the source might be but we are surrounded by industrial and natural noises and situations that can generate odd sounds. This article did not suggest it was apocalyptic as many reports hyped early on, but I can understand that this form of pollution can be disconcerting.

UPDATE: (7-Sept-2012) Here is an interesting idea… is it fish?

A number of tips led us to the University of Washington’s Marine Biology program. Yes, the Midshipman fish, an ugly creature with an odd mating call, could indeed be the sound.

Nearby buildings or the hulls of ships could be acting as giant sub-woofers carrying the low frequency sound for miles.

    From the King 5 story: “The neighboring large industries say they aren’t to blame.”

    One of those industries is Nucor steel which does run at night. It’s great free fun to watch red hot glowing steel being extruded. Not surprisingly the plant makes a lot of noise. How well has this been investigated? I believe there are other marine industries at the mouth of the Duwamish River that operate at night. I would still suspect those operations as the prosaic cause.

    A frequency spectrum analysis yields that there are several resonance frequencies. Eg. there are peaks at 68Hz, 198Hz, 264Hz, as well as multiples thereof. The corresponding wavelengths are 4.86m, 1.67m, and 1.25m. The lengths of resonance bodies causing those wavelengths would be half of that, that is, 2.43m, 0.84m, 0.62m, respectively.
    Actually, the spectrum fits the resonance of a box with the side lengths 2.43m, 0.84m, 0.62m.

      The spectrum of the “fish” signal, by the way, has peaks at 88Hz and multiples thereof. That wouldn’t exactly match the lowest box resonance frequency of 68Hz, but if the signal is strong, it could make the box swing nonetheless. Anyway, I wouldn’t be looking for buildings and ships but for a box of the size 2.43m x 0.84m x 0.62m which is partially in the water.

        Forget the fish. The size of the box would fit those GSM antennas on top of buildings, perhaps they’re excited by wind?
