It creeps in slowly in the dark of night, and once inside, it almost never goes away.

It’s known as the Hum, a steady, droning sound that’s heard in places as disparate as Taos, N.M.; Bristol, England; and Largs, Scotland.

But what causes the Hum, and why it only affects a small percentage of the population in certain areas, remain a mystery, despite a number of scientific investigations.

Reports started trickling in during the 1950s from people who had never heard anything unusual before; suddenly, they were bedeviled by an annoying, low-frequency humming, throbbing or rumbling sound.

The cases seem to have several factors in common: Generally, the Hum is only heard indoors, and it’s louder at night than during the day. It’s also more common in rural or suburban environments; reports of a hum are rare in urban areas, probably because of the steady background noise in crowded cities.

Who hears the Hum?

Only about 2 percent of the people living in any given Hum-prone area can hear the sound, and most of them are ages 55 to 70, according to a 2003 study by acoustical consultant Geoff Leventhall of Surrey, England.

Most of the people who hear the Hum (sometimes referred to as “hearers” or “hummers”) describe the sound as similar to a diesel engine idling nearby. And the Hum has driven virtually every one of them to the point of despair. [Video: Listen to 6 Spooky Sounds]

“It’s a kind of torture; sometimes, you just want to scream,” retiree Katie Jacques of Leeds, England, told the BBC. Leeds is one of several places in Great Britain where the Hum has recently appeared.

“It’s worst at night,” Jacques said. “It’s hard to get off to sleep because I hear this throbbing sound in the background. … You’re tossing and turning, and you get more and more agitated about it.”

Being dismissed as crackpots or whiners only exacerbates the distress for these complainants, most of whom have perfectly normal hearing. Sufferers complain of headaches, nausea, dizziness, nosebleeds and sleep disturbances. At least one suicide in the United Kingdom has been blamed on the Hum, the BBC reports.

The Hum zones

Bristol, England, was one of the first places on Earth where the Hum was reported. In the 1970s, about 800 people in the coastal city reported hearing a steady thrumming sound, which was eventually blamed on vehicular traffic and local factories working 24-hour shifts.

Another famous hum occurs near Taos, N.M. Starting in spring 1991, residents of the area complained of a low-level rumbling noise. A team of researchers from Los Alamos National Laboratory, the University of New Mexico, Sandia National Laboratories and other regional experts were unable to identify the source of the sound.

Windsor, Ontario, is another Hum hotspot. Researchers from the University of Windsor and Western University in London, Ontario, were recently given a grant to analyze the Windsor Hum and determine its cause.

Researchers also have been investigating the Hum in Bondi, a seaside area of Sydney, Australia, for several years, to no avail. “It sends people around here crazy — all you can do is put music on to block it out. Some people leave fans on,” one resident told the Daily Telegraph.

Back in the United States, the Kokomo Hum was isolated in a 2003 study financed by the Indiana city’s municipal government. The investigation revealed that two industrial sites — one a Daimler Chrysler plant — were producing noise at specific frequencies. Despite noise-abatement measures, some residents continue to complain of the Hum.

What causes the Hum?

Most researchers investigating the Hum express some confidence that the phenomenon is real, and not the result of mass hysteria or hearers’ hypochondria (or extraterrestrials beaming signals to Earth from their spaceships).

As in the case of the Kokomo Hum, industrial equipment is usually the first suspected source of the Hum. In one instance, Leventhall was able to trace the noise to a neighboring building’s central heating unit.

Other suspected sources include high-pressure gas lines, electrical power lines and wireless communication devices. But only in a few cases has a Hum been linked to a mechanical or electrical source.

There’s some speculation that the Hum could be the result of low-frequency electromagnetic radiation, audible only to some people. And there are verified cases in which individuals have particular sensitivities to signals outside the normal range of human hearing.

Medical experts are quick to point out that tinnitus (the perception of sound when no external noise is present) is a likely cause, but repeated testing has found that many hearers have normal hearing and no occurrences of tinnitus.

Environmental factors have also been blamed, including seismic activity such as microseisms — very faint, low-frequency earth tremors that can be generated by the action of ocean waves.

Other hypotheses, including military experiments and submarine communications, have yet to bear any fruit. For now, hearers of the Hum have to resort to white-noise machines and other devices to reduce or eliminate the annoying noise.

Leventhall, who recommends that some hearers turn to cognitive-behavioral therapy to relieve the symptoms caused by the Hum, isn’t confident that the puzzle will be solved anytime soon.

“It’s been a mystery for 40 years, so it may well remain one for a lot longer,” Leventhall told the BBC.

Louisville residents searching for the source of an unexplained ground-shaking boom can scratch another theory off the list.

A Loudon County resident speculated on Thursday that the noise could have come from maintenance on an underground pipeline. The Plantation Pipe Line Company operates a large liquid refined petroleum pipeline that runs from Knoxville to Macon, Georgia. The pipeline is co-owned and operated by Kinder Morgan.

Emily Mir with Kinder Morgan’s media relations department contacted 10News on Friday morning and indicated there were no recent operations that would have created the noise. Furthermore, the pipeline in question is located around 10 miles from the Lashbrooke subdivision.

The Lashbrooke subdivision in Louisville enjoyed a quiet and sun-bathed afternoon on Thursday. The peaceful surroundings of the affluent neighborhood along the Tennessee River lend no hint that its residents suffer from shell-shock.

“It’s scary-loud. It’s loud enough that it makes your heart stop for a second,” said Andy Wombold. “It sounds like a shotgun or an explosion of some kind.”

Wombold and dozens of other residents in the neighborhood are unable to say exactly what “it” is. All they know is the mysterious booms have provided several rude awakenings that sent residents scrambling in fear.

“Last Monday, about a week and a half ago, it was around 3 a.m. and it was, ‘Pow!’ All the sudden we heard a loud explosion. It sounded like it came from inside our house. It shook the walls. It shook the floor. It shook the ceiling,” said Wombold.

Wombold said he ran upstairs to check on his parents and ran into his father who was already headed downstairs.

“We thought maybe a gas line had exploded and maybe our house was going to blow up. We thought it was really serious,” said Wombold.

“It was like lightning struck directly beside the house,” said neighbor Dwayne Jones. “I jumped out of bed and ran outside. Then I saw a clear sky full of stars and knew it wasn’t lightning. The ground was still shaking for a little bit. It was like a big sonic boom. Just the whole house shakes. I never heard anything like it.”

Several residents called emergency dispatchers and Blount County deputies responded to the scene. However, they were unable to find any problems in the neighborhood. Marian O’Briant with the Blount County Sheriff’s Office said deputies also checked with local rock quarries and confirmed there were no blasting operations.

Residents said the booms continued for several days.

“It would happen in the middle of the night, in the morning, at all different times,” said Jones. “It was like they would get a little weaker as the days went by, but it was still really jarring.”

“You generally heard one big boom and then a bunch of aftershocks in quick succession. I don’t know if it was an echo off the river or what,” said Wombold.

A Tennessee National Guard spokesman confirmed there were no military operations in the area that would create the ground-shaking experience.

T-DOT told 10News there are no construction projects in the area that could explain the noise.

The USGS said there has only been one earthquake in Tennessee in the last couple of weeks. That tremor only registered 1.4 on the Richter magnitude scale and was in Tiptonville along the Mississippi River.

“The other thing we figured is it might have been something with the power lines,” said Jones. “We have these very large lines that go directly through the neighborhood and across the river, but we never had any power outages.”

TVA confirmed there have been no problems with the lines near the Lashbrooke subdivision.

The mystery may be more difficult to solve as the frequency of the booms decreases. Wombold said it has been a couple of days since he last heard a boom while Jones indicated he has not noticed the noise since late last week. Blount County dispatchers said the last call they received about the booms was last week.

Whatever the cause, residents said the booms repeatedly sent an unforgettable and shocking experience through the neighborhood for most of the week.

“Be sure to lock your doors because who knows where that noise is coming from,” joked Wombold. “I just really want to know what caused it.”

Pipeline “Pigging” Possibility?

A Loudon County resident provided another theory about the source of the explosive sounds. Greg Potter from Lenoir City said he had a similar experience a few years ago.

“One night we heard all kinds of booms. It shook the house and the ground,” said Potter. “We called the police. We eventually found out there was a pipeline that runs deep underground in our yard. The pipeline company was doing what they called ‘pigging’ where they shoot something like nitrogen slugs between the product to clear the pipeline.”

The Plantation Pipeline Company (PPC) operates a large pipeline that runs from Knoxville to Loudon and continues to Chattanooga before ending in Macon, Georgia. PPC is co-owned and operated by Kinder Morgan. 10News contacted the company and is awaiting a response to see if any recent operations could have created the noise in Louisville.

Some incidents may be related to meteors but I think the majority of these incidents are a surface phenomena. Meaning faults can be agitated or jarred in a snap-pull or grinding fashion without disturbing the ground but creating an electromagnetic aura of lights or a rumbling sonic boom that propagates through the air in its wake. These incidents are becoming more numerous and are now popping up basically across the globe — an indication that whatever forces are creating these events — could be intensifying. Some mention underground construction, bunkers and tunnels or stealth mystery aircraft as likely culprits but there are documented reports of these incidents in the U.S. that go back as far as the 1850′s. NASA has even heard these noises from across the cosmos and can’t explain them. A spokesman for NASA Goddard Space F. Center said: “There is something new and interesting going on in the universe,” said Alan Kogut of NASA’s Goddard Space Flight Center in Greenbelt, Md. See report: NASA Noise

You can even find reports of these incidents going back to 1958, where on June 28th, the University of Florida in Gainesville was shaken by a series of unexplained mysterious booms. More than 84 reports of broken windows were reported to police from the incident. Though the incident was investigated by the U.S. military; and presumably blamed on an aircraft- to this day, it remains unsolved. See: 1958 News Archive

In 2009, a quiet neighborhood in Minnesota was similarly terrorized by unexplained noises and shaking- Minnesota story. The state of Georgia also reports an incident. See Georgia. It’s happening in Canada. See Windsor. It’s happening in the UK also. See Saffron Waldon. Is this a seismic phenomena as some geologists are now claiming? Some of the reports go back to India to the 19th century as the booms were then called barisal guns. Some experts believe the mystery booms could be related to an explosive release of methane gas from a cavity in the Earth as a result of cosmic rays, a fault slip or movement. They call them mistpouffers. Most scientists are perplexed about what’s actually causing the mystery booms. In light of all the increased number of reports now pouring in from all across the globe, one gets the feeling that some major geological event may be building under the ground.

      Last night we had several loud BOOMS house did not shake. At first we thought a tree fell on the roof..Nope..checked out the inside and outside of the house.nothing. We had several booms. Anyone know why?

  2. Interesting. C – thanks for letting us know…

    The booming has been happening here in West Tennessee close to the river for over 15 years. Nothing as bad as some of the other reports of beds moving or windows breaking, but the house does shake sometimes. Sounds like thunder, but no clouds or storms in the area. All times of day and night. Doing it right now. I thought for awhile it maybe ground penetrating radar, someone looking for oil? Just hills rumbling? Why?
