This is an article about how sounds you cannot hear affecting your emotions. Like why you may feel scary in "spooky" places, or how when certain sounds that are inaudible may make you feel happy or mad.

Saying MP3, AAC, Ogg Vorbis, and MPC, take the "heart and emotion" out of the music, would be scientifically correct now,

It states:

"A BIZARRE experiment in soundless music has revealed how people's emotions are affected by noises they cannot hear.
Scientists have begun analysing the responses of 250 people who took part in the study into the effects of infrasound, carried out at Liverpool's Metropolitan Cathedral last September.
They showed the audience's emotions intensified as the inaudible sound vibrations, too low for the human ear to perceive, were blasted out during a 50-minute piano recital.




Those feeling uncomfortable when the concert began, found their mood turning to anger.
Others, who had felt happy, started to notice sensations of joy.
Some physical affects were also experienced, including tingling in the back of the neck and a strange feeling in the stomach.
Ciarán O'Keeffe, a researcher on the project who has since taken up a lecturing post at Liverpool Hope University's Psychology department, said: "When the infrasound was switched on, people experienced different emotional responses to it.
"The feelings that the listeners recorded at the time are in line with anecdotal evidence of experiences in places that have infrasound. "Generally people found that they experienced more in depth versions of the emotions they were feeling before the infrasound began."

The infrasound vibrations were created by an ultra-low loudspeaker inside a 12m-long, 30cmwide drainpipe cannon.
The contraption sent out subtle pulses at certain moments during two of the four pieces of music played by Russian pianist Evgenia Chudinovich.
During the concert, guests were asked to fill in questionnaires composed by psychologists about how they feel at different moments.
Infrasound has been used by organists in churches and cathedrals for at least 250 years to create grand, high-octane music.

Some scientists also claim it is the cause of the uneasy feelings and changes of emotion experienced in places believed to be haunted.

Mr O'Keefe added: "When places affect people physically and they aren't able to explain it, they often attribute their feelings to being near a ghost."
As the concert at the Metropolitan Cathedral was the first of its kind, the experiment must be repeated to ensure that the affects are caused by infrasound and not by another stimulus.

Two more recitals will be held on the same day in the Royal Festival Hall, London, with the vibra-tions created at varying points during the recital.

If successful, this will also prove the emotions were not caused by the atmosphere of the Cathedral.

The Soundless Music research is being under-taken by a team musicians, scientists and psychologists with the original concert held as part of the Symposium art and science conference run by John Moores University, The Wellcome Trust and Sciart Consortium."

That was a very interesting read Thasp! Bravo.

That's crazy!!!

But what creates inaudible sounds when you think your not alone...

Worrying stuff

I used to have a set of Radio Shack Super tweeters that start out at 20,000 hz and go to 45,000 you couldn't hear themif you diconnected the main speakers, but if you disconnected them you could tell a difference in the music, it seemd to lose it "brillance" and sounded flat even though the main speakers were top rate speakers with a 20-20000hz freq response. I for one beleive it's possible.

Phsyco acoustics, My friend Dr. Gaston worked in this field for many years. Staggering military applications actually.

This could control peoples minds

A 5 Hz signal, extremely loud, causes you to shit/puke uncontrollably.

Hmmm.... Experiment IV.

That's what you lose in lossy formats. You only "HEAR" the sound - u no longer "FEEL" it..... which is okay for some applications. Sound by nature creates a change in the air space around us. Our ears are finally tuned to pic up enough of these changes for our brains to recognize it as music, speech etc. But we need to remember, that our other senses may also pick up on these changes in the airspace, i fact, it would be naive NOT to believe that. We are affected by the physical world around us. Changes in this physical properties affect ALL our senses to some degree. In terms of sound, our hearing is the main sense affected, and thus lossy compression formats focus on maintain this. Yes, in gaining space on our hard drives, we sacrifice the way our other senses react to music, but this is fine for the portable music and cheap PC sound system world many people live in. But that's also why uncompressed (or less compressed) mediums such as CD's will always have a market (IF the companies behind them realise WHERE their market lies!!!)

Actually, you can use lossless, and still have a file half the size. Like FLAC for example.

Weird stuff, but interesting

If a tree falls in the forest and noone is there to hear, it does it make a sound?

very fucking gay, go to our site , UGB BITCH
