10 Most Annoying Noises

10. Persistent music late at night

Persistent music late at night

One of the most widespread complaints received by the Noise Abatement Society concerns loud music being played by neighbours at night. For the partygoers the music is pleasurable, while for the complainants it is unbearable. Context and control determine how people emotionally interpret the soundscape; a ‘noise’ can be thought of as a sound that is out of place. People can be sensitised to a persistent sound that is out of their control, even if the sound is quiet — this is why some people find a dripping tap so grating.

9. Vicious dog barking

Vicious dog barking

A dog’s bark has almost everything: it can be loud and surprising, it has associations with danger and threat. People’s mental connections to the sound of a dog barking make them feel bad, because vicious dogs conjure up unpleasant memories. The actual sound itself is also irritating because of its rough quality; for most sounds, roughness makes the sound more grating. Acousticians define roughness as rapid fluctuations in how powerful a sound is (20-200 cycles per second). The fluctuations have to be fast enough that they are heard as part of the sound’s texture, rather than as individual changes in the sound’s loudness.

8. Thunder

Thunder

The main reason thunder is so frightening to small children is because it suddenly becomes so loud. Similarly frightened responses can arise from fireworks or loud gun shots. Any sound can be aversive if it is loud enough. The cochlea, the sensory organ for sound in the inner ear, can be damaged by loud sounds. As the amplitude of sound waves in the cochlea approaches the threshold for this damage, the sounds cause pain.

7. Flatulence

Flatulence

Volunteers in an experiment by Trevor Cox at the Acoustics Research Centre at the University of Salford ranked the noise made by a whoopee cushion as one of the most irritating. It’s not loud but its association with embarrassment is likely to be the root of its annoyance. Some sensitive souls find the sound of flatulence unpleasant to hear – although for many flatulence is a staple of comedy, from Dekh Bhai Dekh and Sarabhai Vs Sarabhai. In Japan, women in public toilets found the sound of urination so embarrassing that they would run the electric hand driers to mask the tinkling. The Japanese solution has been to pipe singer Barry Manilow’s records into public loos.

6. Baby crying

Baby crying

Evolution has made us particularly sensitive to the sound of a baby crying. The sound spectrum of crying is composed mostly of frequencies from 2000 to 4000 cycles per second. These frequencies are perceived as ‘sharp’, an unpleasant acoustic property. The evolutionary reason for being more sensitive to sharp and rough sounds is probably so that we are roused to action by human shrieks and babies crying.

5. Woman  screaming

Woman screaming

The sound of a woman screaming is even more upsetting than a baby crying. Evolutionarily, this alarm call would highlight danger to the tribe, in order to attract aid or instigate retreat. In one of my own experiments, participants occasionally smiled at a female scream because it reminded them of horror movies. This probably happens because cultural associations can reverse the alarming effects of a piercing scream.

4. Knife on a bottle

Knife on a bottle

In a study of piercing sounds by Dr Sukhbinder Kumar and his colleagues at Newcastle University’s Medical School, the noise of a knife scraping a bottle was rated as even more annoying than fingernails on a blackboard. Other sharp and rough sounds that have been rated as highly irritating include railroad brakes, grinding machinery and a metal rake against a slate stone.

3. Fingernails on a blackboard

Fingernails on a blackboard

This is a grinding sound in the frequency range associated with sharp noises. However, sharpness alone is not what makes this sound excruciating. It’s also very rough. The effect of nails on a blackboard is very difficult to reproduce with a recording, so although many lab studies using recorded sounds find this sound to be less annoying than others, it’s often reported to be individuals’ number one hated noise.

2. Microphone feedback

 Microphone feedback

When you hear the high-pitched sounds of microphone feedback, does it make the hair on the back of your neck stand up, or do you just want to stick your fingers in your ears? Of all the sharp noises reproduced in the lab this is loudest and sharpest and, when tested, a University of Salford experiment rated it number two for horribleness.

1. Vomiting

Vomiting

Does the sound of vomiting make you feel queasy? In a study of 385,000 internet responses to 34 unpleasant sounds, vomiting was rated as the worst. The sound of vomiting is so nauseating because of your mental associations to it. It brings up people’s most repulsive feelings of bodily discharge — in all its unhygienic glory. Interestingly, the acoustic properties of vomiting are not particularly noxious: it is neither rough nor sharp. Sensations associated with disgust are especially well learned by mammals because this skill is necessary to avoid poisonous foods.

Top 10 Space Stories of the Decade

10. Saturn Moon Titan Explored

Saturn Moon Titan Explored

On Jan. 14, 2005, the European Space Agency’s Huygens probe dropped through Titan’s atmosphere after a seven-year trek attached to NASA’s Cassini spacecraft. Huygens wasn’t designed to live for very long after atmospheric reentry, but it unveiled a mysterious outer solar system world to us for the first time.

Before this mission, very little was known about Saturn’s largest moon, and scientists were unsure whether Huygens would land on a rocky surface or in an ocean. Titan’s thick atmosphere  composed of primarily nitrogen and clouds of methane and ethane, about 50 percent thicker than our atmosphere signaled to scientists that Titan was similar to a young Earth.

Observations from the Huygens probe and Cassini spacecraft tell us that Titan and Earth share many features, such as sand dunes and lakes. But these features are heavily laced with organic molcules that could support life, leading researchers to speculate about Titan’s potential to nurture microbes.

9. Moon Water Confirmed

Moon Water Confirmed

India’s Chandrayaan-1 satellite confirmed the presence of water on the moon in September 2009, building on flyby observations by other probes on their way elsewhere. Although the lunar surface is still drier than Earth’s driest desert, evidence of water is there, hinting at a solar wind interaction with the moon’s surface that produces water and hydroxyl molecules.

It may not be an oasis up there, but future moon colonists could extract and purify the traces of water from the surface to use for drinking, food cultivation, oxygen and fuel. Or, our colonists could take a trek to the moon’s poles to mine water from the deepest craters

On Oct. 9, 2009, NASA dropped a spent rocket into a crater to produce a 100-foot-wide hole. They found water there too. That rocket produced a massive plume of dust that was analyzed by the Lunar Reconnaissance Orbiter (LRO) and ground-based observatories. At least 25 gallons of water ice was detected in the plume.

8. Organic Chemistry Collected from Comet’s Tail

 Organic Chemistry Collected from Comet's Tail

In 2004, the NASA Stardust mission chased after Comet Wild 2 to find out if the icy mass contained the building blocks for life, since meteorites found on Earth contained organic chemistry that originated from space. Sure enough, in August 2009, NASA announced that they had found samples of glycine  an amino acid  in Stardust’s collection plates. It didn’t stop there, there’s increasing evidence that exoplanets orbiting distant stars contain organic chemistry in their atmospheres.

In 2008, organic chemicals were detected in the disk surrounding a star called HR 4796A, 220 light-years from Earth. And most recently, NASA’s Hubble and Spitzer space telescopes detected carbon dioxide, methane and water vapor in the atmosphere of an exoplanet called HD 209458b.

These discoveries, sparked by Stardust, have transformed our understanding about how life may have formed on Earth. They also give us a strong hint that life may not be unique to Earth; the universe appears to be manufacturing organic chemistry everywhere.

7. A Supermassive Black Hole on Our Doorstep

A Supermassive Black Hole on Our Doorstep

There’s a monster living in the center of our galaxy, 26,000 light-years from Earth. By 2008, astronomers tracking the behavior of stars orbiting an invisible point confirmed that the monster is a supermassive black hole called Sagittarius A.

A lone star called “S2,” with a very fast orbit, has been tracked since 1995 around this invisible point. In 2002, Rainer Schödel and his team at the Max Planck Institute for Extraterrestrial Physics announced that the only explanation for S2’s fast orbit was that it was circling a very compact, massive object  a supermassive black hole  that was stopping the star from flinging out of its orbit into space.

In 2008, after S2 completed one 16-year orbit, it was confirmed that the star was orbiting a black hole with a gargantuan mass of approximately 4.3 million suns. The confirmation of a supermassive black hole in the center of the Milky Way boosted the theory that most galaxies contain a supermassive black hole at their cores.

6. Big Bang “Echo” Mapped for the First Time

Big Bang "Echo" Mapped for the First Time

In June 2001, NASA set out to find the ancient “echo” of the Big Bang by mapping the cosmic microwave background (CMB) radiation that buzzes like static throughout the cosmos, using the Wilkinson Microwave Anisotropy Probe (WMAP) .

When the universe was born, vast amounts of energy were unleashed, which eventually condensed into the stuff that makes up the mass of what we see today. The radiation that was created by the Big Bang still exists, but as faint microwaves.

By mapping slight variations in the CMB radiation, the probe has been able to precisely measure the age of the universe (13.73 billion years old) and work out that a huge 96 percent of the mass of the universe is made up of stuff we cannot see. Only 4 percent of the cosmic mass is held in the stars and galaxies we observe; the rest is held in “dark energy” and “dark matter.”

5. Hubble Gets to Grips with Dark Energy

Hubble Gets to Grips with Dark Energy

In 2002, the Hubble Space Telescope was upgraded with a new instrument, the Advanced Camera for Surveys, that revealed the presence of a mysterious force called “dark energy.”

The camera was set up to help researchers understand why Type Ia supernovae were dimmer than expected. Hubble’s observations of these supernovae discovered that they weren’t dimmer because the stars were different (they should all explode with the same brightness). The only explanation was that the universe’s expansion was unexpectedly and inexplicably speeding up. This accelerated expansion was making the light dim over vast cosmic distances. Hubble’s discovery led to a better understanding of what dark energy is — an invisible force that opposes gravity, causing the universe’s expansion to speed up.

4. Eris Discovered; Pluto Demoted

Eris Discovered; Pluto Demoted

In January 2005, Mike Brown and his team at Palomar Observatory, Calif. discovered 136199 Eris, a minor body that is 27 percent bigger than Pluto. Eris had trumped Pluto and become the 9th largest body known to orbit the sun.

In 2006, the International Astronomical Union (IAU) decided that the likelihood of finding more small rocky bodies in the outer solar system was so high that the definition “a planet” needed to be reconsidered. The end result: Pluto was reclassified as a dwarf planet and it acquired a “minor planet designator” in front of its name: “134340 Pluto.”

Mike Brown’s 2005 discovery of Eris was the trigger that changed the face of our solar system, defining the planets and adding Pluto to a growing family of dwarf planets.

3. Dark Matter Detected

Dark Matter Detected

In the summer of 2006, astronomers made an announcement that helped humans understand the cosmos a little better: They had direct evidence confirming the existence of dark matter — even though they still can’t say what exactly the stuff is. The unprecedented evidence came from the careful weighing of gas and stars flung about in the head-on smash-up between two great clusters of galaxies in the Bullet Cluster.

Until then, the existence of dark matter was inferred by the fact that galaxies have only one-fifth of the visible matter needed to create the gravity that keeps them intact. So the rest must be invisible to telescopes: That unseen matter is “dark.”

The observations of the Bullet Cluster, officially known as galaxy cluster 1E0657-56, did not explain what dark matter is. They did, however, give researchers hints that dark matter particles act a certain way, which they can build on.

2. Mars Surface Gives up Signs of Water

Mars Surface Gives up Signs of Water

In 2008, NASA’s Mars Phoenix lander touched down on the Red Planet to confirm the presence of water and seek out signs of organic compounds. Eight years before, the Mars Global Surveyor spotted what appeared to be gullies carved into the landscape by flowing water. More recently, the Mars Expedition Rovers have uncovered minerals that also indicated the presence of ancient water. But proof of modern-day water was illusive.

Then Phoenix, planted on the ground near the North Pole, did some digging for samples to analyze. During one dig, the onboard cameras spotted a white powder in the freshly dug soil. In comparison images taken over the coming days, the powder slowly vanished. After intense analysis, the white powder was confirmed as water ice.

This discovery not only confirmed the presence of water on the Red Planet, it reenergized the hope that some kind of microbial life might be using this water supply to survive.

1. Alien Planets Spotted Directly

Alien Planets Spotted Directly

The first alien planets — called exoplanets — were being detected in the early 1990s, but not directly. In 2000, astronomers detected a handful by looking for a star’s “wobble,” or a star’s slight dimming as the exoplanet passed in front of it. Today we know of 400 exoplanets. In 2008, astronomers using the Hubble Space Telescope and the infrared Keck and Gemini observatories in Hawaii announced that they had “seen” exoplanets orbiting distant stars. The two observatories had taken images of these alien worlds.

The Keck observation was the infrared detection of three exoplanets orbiting a star called HR8799, 150 light-years from Earth. Hubble spotted one massive exoplanet orbiting the star Fomalhaut, 25 light-years from Earth. These finds pose a profound question: How long will it be until we spot an Earth-like world with an extraterrestrial civilization looking back at us?

10 Superhuman Real Life Superpowers

10.Human Magnets

human-magnet

You will find many individuals on the planet that claim to get the amazing property to develop a magnetic field that causes metal to stick for their skin, which will be remarkable if this were truly true. Obviously, their forces aren’t limited to steel, in addition they get plastic to stick too and they don’t trigger any sort of troubles with electronic device.

Turns away they’re maybe not truly magnetic, but rather have amazingly tacky epidermis, which can be just total, however, it will be nice to help you instead of placing it in your pocket to stick your telephone to your own torso, I guess.

9.Super Memory

daniel tammet

Daniel Tammet recalls pi to over twenty  two thousand digits, can talk five languages and continues to be studied extensively by neurobiologists because he is able to clarify precisely how he does it. Do n’t get your hopes up though, he can do all this because he has synaesthesia, where he experiences shapes, textures and colors when he thinks of numbers and phrases.

In a single case he then appeared in a interview talking the terminology and was able to understand audio Icelandic in a week.

8.Mr Eat-all

Michel Lotito

Have you ever ever not been so full that you just wanted to consume a Cessna plane that was whole? How about a coffin? Possibly a computer? You’re a regular person if you answered no to most of these questions, but you’re also not a person using an real super strength. Michel Lotito, also known as Mr Eat-all, had the power to consume and, moreover, shit out anything you can think of without the damage, including poisonous substances.

If the typical person consumed any of those items subsequently they’d be left with serious problems, but maybe not Mr Eat-all, although with that mentioned so his strength wasn’t just best he did also perish at the age of 57.

7.Tame Wild Animals

Kevin Richardson

Richardson gets the ability to tame just about any animal, it seems, as long as they are reared by him from infancy, that might not seem spectacular initially, but a pride of lions tries and join without any taming approaches that are conventional and see how well that goes for you.

Taming big cats isn’t sunshine and all puppy dogs, there’s quite a serious problem with having a pride of lions treat you as one of their very own, for instance they’ll also perform with battle with you, which, as you are able to imagine, is quite painful.

6.Strongest Man in History

Louis Cyr

Louis Cyr proved to be a strong man that is classical, except with one important variation, he was much better than everybody else by a long shot. Doing a back lift he managed to raise just under two tonnes, he also wrestled a guy around 2 feet taller than him and won.

His record breaking efforts have not yet been overtaken by anybody including these who’ve obtained steroids, even today.

5.The Human Computer

Shakuntala Devi

Shakuntala Devi was an Indian social worker with some psychological abilities that are quite amazing, Some may call her a genius in mental calculating; I, however, might call her a machine from the future that was destroyed in the search for Sarah Connor.

Shakuntala had the ability in blistering speed to perform mental calculations, for instance she was able to compute the cube root of sixty one million, six-hundred and twenty-nine-thousand, eight hundred and seventy five before the person checking her answers could write her answer down.

He showed his strength and endurance by killing fully grown bulls with one blow and participating in three different hundred-man fighting competitions in a row, He showed endurance and his strength by killing fully bulls that were grown with one blow and participating in three distinct hundred-man fighting competitions in a row, In which he fought 100 trained karate experts a day off for three days.

3.Iceman

Ice man WimHof

WimHof does possess a whimsical name, he also has got the ability to withstand insanely low temps that would kill many people were they exposed for how long to them that he sets through himself.

Ice man ran a marathon in –20 °C (-4 °F) weather in only a pair of short pants, he also tried to scale Mount Everest in precisely the same attire, but couldn’t ensure it is all the way up because of a foot injury. He also holds the world record for the greatest quantity of time spent submerged in ice.

2. Ultra Endurance

Dean Karnazes

Humans have the capacity to be the very best marathon runners in nature, however, Dean Karnazes is not worse than the normal person can ever expect to be.
Karnazes has run a 350 mile (or 560 kilometer) marathon in 80 hrs without any sleep, he also ran a marathon a day for 50 consecutive days.
 His ability to to perform arrives to having outstanding muscles that simply don’t exhaust the same manner many people’s muscles do, therefore it’s not merely a matter of easy training.

10 Islands that may disappear

The rise of the ocean level could function as the biggest menace to the entire world in the days in the future. If global temperatures continue to go unabated sea  levels all over the world could increase by as much as five yards incoming generations, that may seriously impact low lying islands and states. Sea levels have increased 6 to 8 ins in the previous 100 years. Also, it’s been discovered that Antarctic is now shedding around 159 billion tonnes of ice every year for the island countries currently living at sea level, which presents a problem that is new.

Let’s check out 10 such islands which is impacted by climate change crisis.

Solomon Islands

Solomon Islands

Solomon Islands is a sovereign nation composed of a substantial number of islands in Oceania lying to the east of Northwest and Papua New Guinea of Vanuatu.

As a result of debilitating aftereffects of climate change the Low Lying lands of the Solomon Islands are severely affected with decreased property area and crops failing.

Maldives

Maldives

Maldives is just another island that might be shortly lost to rising ocean levels. With the average floor level altitude of 1.5 metres above sea level, Maldives is our planet’s cheapest state.  And because of the geographic location it’s due to inundation from climate change, the most state.

President of the Maldives Mohamed Nasheed stated that “If carbon emissions continue at the speed they’re rising nowadays, my state will likely be submerged in seven years.”

Republic of Cape Verde

Republic of Cabo Verde

Republic of Cabo Verde is an island nation spanning an archipelago of 10 islands in the Atlantic Ocean that is central. Cape Verde is exceptionally exposed to climate change and sea level increase as it detrimentally affects the environment, market and society.

Palau

Palau

Palau, formally the Republic of Palau, is an island region situated in the western  Pacific Sea. The citizenry of around 21,000 is spread across 250 islands developing the developed chain of the Caroline Islands. As global warming causes sea levels to inch up, Palau is facing severe floods which makes inhabitants live under constant fear of their homes being washed away.

Fiji

Fiji

Fiji covers a complete part of some 194,000 square kilometres (75,000 sq mi) that around 10% island. The nation includes much more than 500 islets, amounting to some total property area of circa 18, 300 square kilometers, and an archipelago of more than 332 countries, that 110 are forever inhabited.

Based on 4th examination report of IPCC, Fiji is currently experiencing coastal erosion because of which human arrangement and water resources have reached an increased threat because of sea level rise.

Torres Strait Islands

Torres Strait Islands

Torres Strait Islands are a small grouping of at the least 274 tiny islands which lie in Torres Strait. Climate change triggers some serious issues within this island, like floods damage erosion, coral bleaching etc.

Seychelles

Seychelles

Seychelles includes 115 granite and coral islands in the western Indian Ocean, having a population of 87,122. A rise of just three feet would submerge the Maldives and make them uninhabitable. Also it has witnessed the world`s worst coral die-off.

Tegua

Tegua

The United Nations reported the approximately 100 residents of Tegua, part of the Torres Strait Islands positioned in the Pacific, the primary climate change refugees in 2005.

The sea-level also increased, triggering in regards to a quarter of the flooding, although a lot of the flooding was because the island sunk almost five inches between 1997 and 2009.

Micronesia

MICRONESIA

Micronesia is just a subregion of Oceania and contains thousands of tiny countries while in the western Pacific Ocean. There are four primarily archipelagos along with a number of other outlying destinations.

The sea water is regularly killing off food plants. Scientists warn that a one meter rise that is tiny would produce the area uninhabitable.

Kiribati islands

Kiribati

Kiribati is definitely an island country within the tropical Pacific Sea that is main. The country consists of 32 atolls and one raised coral island, Banaba. It’s a populace 697, of 102.

Due to the increasing sea level, nearly all of it territory disappeared under the ocean which caused most of its population to move to another island, Tarawam.
