[QUOTE]The most annoying sound in the world is the scrape of a knife down the side of a glass bottle - with the horrible screech of nails on a blackboard placing in fifth. The chart is based on magnetic brain images of how sounds provoke a response within the amygdala, the brain's 'emotion centre'. People also find nails on a blackboard, bicycle brakes, and electric drills highly unpleasant. The research hints that we evolved this response long before blackboards, bottles and even knives existed. All the sounds in the top ten are similar in frequency range to human distress signals such as female screams or babies cvrying. "It appears there is something very primitive kicking in," says Dr Sukhbinder Kumar, the paper's author from Newcastle University. "It's a possible distress signal from the amygdala to the auditory cortex." All the sounds come from roughly the same range of high-pitched frequencies, say the Newcastle scientists that made the discovery. Anything in frequency range of around 2,000 to 5,000 Hz was found to be unpleasant. Dr Kumar explains: "This is the frequency range where our ears are most sensitive. Although there's still much debate as to why our ears are most sensitive in this range, it does include sounds of screams which we find intrinsically unpleasant." Researchers at the Wellcome Trust Centre for Neuroimaging at UCL and Newcastle University used functional magnetic resonance imaging (fMRI) to examine how the brains of 13 volunteers responded to a range of sounds. Listening to the noises inside the scanner they rated them from the most unpleasant - the sound of knife on a bottle – to pleasing - bubbling water. Researchers were then able to study the brain response to each type of sound. Researchers found that the activity of the amygdala and the auditory cortex varied in direct relation to the ratings of perceived unpleasantness given by the subjects. The emotional part of the brain, the amygdala, in effect takes charge and modulates the activity of the auditory part of the brain so that our perception of a highly unpleasant sound, such as a knife on a bottle, is heightened as compared to a soothing sound, such as bubbling water. Scientifically, a better understanding of the brain's reaction to noise could help our understanding of medical conditions where people have a decreased sound tolerance such as hyperacusis, misophonia (literally a "hatred of sound") and autism when there is sensitivity to noise. Professor Tim Griffiths from Newcastle University, who led the study, says: "This might be a new inroad into emotional disorders and disorders like tinnitus and migraine in which there seems to be heightened perception of the unpleasant aspects of sounds." The worst sounds in the world 1. Knife on a bottle 2. Fork on a glass 3. Chalk on a blackboard 4. Ruler on a bottle 5. Nails on a blackboard 6. Female scream 7. Anglegrinder 8. Brakes on a cycle squealing 9. Baby crying 10. Electric drill[/QUOTE] [url]http://uk.news.yahoo.com/brain-research-reveals-what-is-the-most-annoying-noise-in-the-world.html[/url]
I thought this was :v: [media]http://www.youtube.com/watch?v=0cVlTeIATBs[/media]
I personally enjoy the sound of a female scream
how 'road-works at 7 am' didnt make it on there i'm amazed what i'd give for a knife on a bottle round here
I've never heard a knife on a bottle, or fork on a glass, but chalk on a blackboard? The only cringing that happens is if my fingernail scrapes board, augughgahhh
I'm disappointed. I was expecting there to be a clip or something of the sounds for us to hear.

What about motherfucking polystyrene.
I have this special can opener that separates the metal instead of puncturing it. If I work it too fast the most cringing sound + vibration ever goes up my arm. Thing is it's hardly audible, but sounds like a mix of 3 and 1 together. some sounds from the list found here.

Why is there no mosquito buzzing sound on that list?
Glass & bottles: your ear's worst enemies.
I really hate the creaky sound polystyrene packing stuff makes. Really bugs me for some resason.
No no guys [video=youtube;TgF9ZlI_R-8]http://www.youtube.com/watch?v=TgF9ZlI_R-8[/video]
Broken vacuum cleaner Old blender
How is Japanese autotune not on that list. Specifically that one blue woman that screams bloody murder that's named kawaii-Miku or some shit.
Also shrinkwrap.
skrillex should use those sounds in his next song unless he already does
I though it was this [video=youtube;D5eFk5x0o44]http://www.youtube.com/watch?v=D5eFk5x0o44[/video] and this [video=youtube;R4em3LKQCAQ]http://www.youtube.com/watch?v=R4em3LKQCAQ[/video] [editline]15th October 2012[/editline] actually AC is less annoying than JB
UVB-76
The most cringe-worthy sound for me is that little "f-nap" noise that laminated paper makes when you flick it against your skin. Until I was ten, I literally felt like throwing up every time I heard it.

[QUOTE]Baby crying[/QUOTE] ^By FAR the most annoying sound in the world
I hate the sound of metal eating utensils rubbing against each other. I don't even know why, it's just so unbearable to me. Also biting on metal eating utensils and sliding it out of your clenched teeth. Cringes me up.

That high frequency tone that only young people can hear.
A local radio station did a piece on this, and played each sound. Bastards.
I actually never found nails on a chalkboard irritating,or annoying. Others have,but not me.
[QUOTE=Lufttygger306;38047814][quote]Baby crying[/quote] ^By FAR the most annoying sound in the world[/QUOTE] Can't agree enough should have been #1
Chalk actually isn't that bad usually is just a little grainy sound. Tablesaws, good gravy..
