Make a little noise

Sometimes, you can mislead people not only by what you say, but by what you leave out.

Take, for example, the "Moodus noises," that have been reported for centuries near the village of Moodus, Connecticut, in the town of East Haddam.  The sounds themselves are real enough; in fact, the village's name comes from the Algonquian matchitmoodus, which translates to "place of noises."  Rumblings and deep booms are frequent, especially in the vicinity of nearby Mount Tom, and were apparently part of the inspiration for H. P. Lovecraft's terrifying short story "The Dunwich Horror":

No one, even those who have the facts concerning the recent horror, can say just what is the matter with Dunwich; though old legends speak of unhallowed rites and conclaves of the Indians, amidst which they called forbidden shapes of shadow out of the great rounded hills and made wild orgiastic prayers that were answered by loud crackings and rumblings from the ground below...  Noises in the hills continue to be reported from year to year, and still form a puzzle to geologists and other physiographers.  Other traditions tell of foul odors near the hill-crowning circles of stone pillars, and of rushing airy presences to be heard faintly at certain hours from stated points at the bottom of the great ravines; while still others try to explain the Devil's Hop Yard -- a bleak, blasted hillside where no tree, shrub, or grass-blade will grow.

Which is pretty damn atmospheric, you have to admit.

Interestingly, not only was Lovecraft springboarding off a real phenomenon of subterranean noises; the Devil's Hop Yard is also a real place, but it's not as eerie as Lovecraft would have you believe.  In fact, it's pretty enough that it was set aside as a state park, and as far as its diabolical name, no one's quite sure where it came from.  One theory is that a brewer who lived there was named Dibble, and the locals thought using the name for his hop fields was an amusing pun.

Of course, Lovecraft was writing fiction, and actually, he himself was not at all superstitious.  When fans wrote him letters asking for the directions to Dunwich or Arkham or Innsmouth -- or, worse, said they'd been there and wanted to tell him all about it -- he'd respond with admirable patience, "None of those are real places.  I know that for certain, you see, because I made them up."  But the fact remains that the Moodus noises are quite real, even if he and others spun fictional tales around them.  So what are they?

There are dozens of websites and books and YouTube videos claiming that they're supernatural in origin -- citing Native or early colonial legends but not going any further.  They often quote the passage from Charles Skinner's Myths and Legends of Our Own Land:

It was finally understood that Haddam witches, who practiced black magic, met the Moodus witches, who used white magic, in a cave beneath Mount Tom, and fought them in the light of a giant carbuncle [ruby] that was fastened to the roof...

If the witch-fights were continued too long the king of Machimoddi, who sat on a throne of solid sapphire in the cave whence the noises came, raised his wand: then the light of the carbuncle went out, peals of thunder rolled through the rocky chambers, and the witches rushed into the sky.

Most of the paranormal-leaning sources claim the area is haunted -- either by demons, or nature-spirits, or the ghosts of dead humans (or some combination).  They claim that there's a grand mystery still surrounding the place; you'll frequently see phrases like "no good explanation" and "unexplained phenomenon" and "scientists are baffled" (given the frequency of this one, you'd think scientists do little more than shrug their shoulders in helpless puzzlement all day long).  What these books, articles, and websites conveniently leave out is that in fact, a cogent scientific explanation for the Moodus noises was published by a geologist named Elwyn Perry...

... all the way back in 1941.

Perry proposed -- and the explanation has borne up under scrutiny -- that the Moodus noises are caused by minor seismic activity.  The area around Moodus is prone to earthquake swarms, despite its being far from obvious active fault lines.  In the 1980s there were four separate clusters of small quakes, numbering more than one hundred temblors in all, accompanied by a corresponding upswing of reports of booming and rumbling noises, and another swarm occurred in 2011.  Later studies found that the culprit is the Lake Char Fault, the subterranean suture line of a terrane (a microcontinent that ends up welded to a larger land mass) that stuck to North America during the lockup of Pangaea 250 million years ago.  The boundary was a weak spot when the Atlantic Ocean opened, and the tensional stress of rifting is still being released as the land settles.

So there's a completely natural explanation for the Moodus noises, however reluctant some people are to say so.  In a way, I get it; there's a certain frisson you get from accounts of orgiastic rites and conjuring evil spirits from underground caverns, that "it's a geologic fault zone and what you're hearing are small, shallow earthquakes" simply doesn't provide.

But predictably, I'd much rather know the real answer, and if I want to scare myself, I'll just read "The Dunwich Horror."  As far as the supernatural explanations, I tend to agree with journalist/skeptic Carrie Poppy: "We use these as stopgaps for things we can't explain.  We don't believe them because of evidence, we believe them because of a lack of evidence."

Sounding off

Noodling around on Wikipedia, sometimes you run into the oddest stuff.

I was looking something up yesterday and saw an associated link to a page called "List of Unexplained Sounds."  Well, I couldn't pass by something like that, so off I went down that rabbit hole.  As advertised, the page is a compendium of odd noises that have been heard (many have been recorded, so we know that those at least aren't someone's overactive imagination).  There are sound clips for a few of them, so I highly recommend going to the page and checking them out.

Here are a few of the ones listed -- with some possible explanations.

Upsweep is the name given to a sound consisting of a repeated series of rising tones that sound to my ears a little like a siren.  The source of the sound has been identified as being somewhere near 54° S latitude, 140° W longitude, placing it a little less than halfway from New Zealand and Cape Horn.  This, to put it mildly, is the middle of abso-fucking-lutely nowhere; in fact, it's not far from Point Nemo, also known as the "oceanic pole of maximum inaccessibility," which at 48°52.6′S 123°23.6′W is the point on Earth that is maximally distant from land.  There's a conjecture that Upsweep might be some kind of sound generated by underwater volcanic activity, but it's not exactly convenient to go out there and check, so that hypothesis is unproven.

The Bloop is a famous noise, once again heard in the Pacific Ocean, that is ultra-low frequency and extremely high amplitude -- meaning it can travel thousands of miles from its source.  The guess here is that the Bloop is a sound made by large icebergs breaking up (or scraping the seafloor), but I've heard an alternate hypothesis that I like better, which is that it's Cthulhu snoring.  Cthulhu, as you probably know, is the octopoid Elder God who was put into a charmèd sleep in his underwater city of Rl'yeh, where he's waiting for his followers to summon him back.  Why anyone would want to do so remains to be seen, because if you've read any H. P. Lovecraft, you know that the ones who try to reawaken him always end up dying in nasty ways, so it seems to me it might be better to leave him blooping peacefully in Rl'yeh.

Some sounds have only been heard once, but are weird enough to bear mention.  These include Julia, which was given its name because it sounds like someone saying the name in a weird, hooting voice.  This is another one that is probably due to icebergs; its origin was pinpointed to somewhere near Cape Adare, Antarctica, but it was loud enough to be recorded by the entire Equatorial Pacific Autonomous Hydrophone Array.

The Ping is much more local; it's only been reported from the Fury and Hecla Strait between Baffin Island and the Melville Peninsula, Nunavut, Canada.  Although it's likely to be from some kind of marine animal, it's strange enough (and has been reported enough times) that "the Canadian military is investigating."

Not all of them are oceanic sounds.  One of the weirdest is the Forest Grove Sound, heard multiple times near Forest Grove, Oregon in February of 2016.  It was variously described as "a mechanical scream," "a giant flute played off pitch," and "akin to a bad one-note violin solo broadcast over a microphone with nonstop feedback."  There was an investigation, and it was never satisfactorily resolved -- and has not been heard since.

Last, there are the Moodus Noises, heard near Moodus, Connecticut, which unlike the Forest Grove Sound, have been heard for centuries (the indigenous people of the area, mostly from the Narragansett Tribe, supposedly have a long tradition of weird noises coming from nearby Cave Hill and Mt. Tom).  The Moodus Noises have a different Lovecraftian connection -- apparently they were the inspiration for the strange noises that came from Sentinel Hill in the spine-chilling story "The Dunwich Horror."  The more prosaic explanation for the Moodus Noises is that they come from microquakes, but -- needless to say -- there are a lot of people who don't buy that, and think the region is haunted.

So there you have it; a sampler of weird and unexplained sounds.  You should definitely check out the page and listen to some of the clips, which are goosebump-inducing.  While I do think they all have perfectly ordinary natural explanations, being a diehard skeptic doesn't mean I'm immune from getting the creeps now and again.
