MagLev Trains Annoyingly Loud
crem_d_genes writes "You might hear that whistle blowing from that train coming 'round the bend, but tapes of the sounds produced by magnetically levitated and normal trains produced a result that was something of a surprise: Most people rated maglev trains as more disturbing than standard intercity trains. It had been previously known that the two types were about equally loud, but this study analyzed people's reactions to them. Since the effects on the environment will be part of the feasibilty studies for future development, acoustical engineers will have some new challenges. Some participants in the study said the sound made them 'feel insecure, some found it startling, and disliked the occasional shrill sound the maglevs produced.' The researcher postulated that unfamiliarity with the noise might be part of the problem."
The regular trains actually stop at night, you're just hearing the ghost trains, which are noticeably louder than their corporeal counterparts.
If by "obvious" you mean "stated at the end of the freaking Slashdot summary" -- yes, it's obvious.
Some participants in the study said the sound made them 'feel insecure...
No wonder my self-esteem is so low!
Under capitalism man exploits man. Under communism it's the other way around.
btw, i just love the way tou compare people to cattle. Very funny and so true nowadays.
Kinda looks like you're saying that cows are better than people, you woulnd't be from India huh?
Der Tod ist der einzige Weg hier raus!
That is something you'll always have with new technology.
At first the 'look and feel' of windows scared the hell out of me. While now it still does. Oh, wrong example.
Other ecample. At first ringtones used to annoy but now it just irritates me. Oh, wrong example again.
Privacy is terrorism.
I vote that they attach large speakers all over the maglev trains, and play the tie fighter sound while they are going really fast. That'll teach 'em to complain about the noise!!
The annoying sound is the one those people with pacemakers make as the train gets going.
the major advances in civilization are processes which all but wreck the societies in which they occur - A.N. White
Speaking of unfamiliar and disturbing phenomena, go back and read some of the reports on the first helicopters. Some of them are quite humorous. "Somebody's WINDMILL just flew by!"
Always going forward, 'cause we can't find reverse.
this test was actually done the old fashioned, wild-west style.
Test subject puts ear on rail road track, hears train, moves of track.
Test subject puts ear on maglev track, no vibration, doesn't move off track in time - no wonder they freak out!
Guy That Sits One Cube Over ... Annoyingly Loud
... but subscribers can read it now by stopping by my office.
My Slashdot submission about this will be enroute to the Slashdot rejected bin in a few minutes
Also, I'm guessing the maglev goes *much* faster than the wheeled train to make the same overall dbs of sound.

It's actually quite an educative site. It teaches people why it is such an incredibly bad idea to leave javascript enabled when visiting unknown web sites...
.. but tapes of the sounds produced by magnetically levitated and normal trains
Maybe they shouldn't have used magnetic tape around gigantic magnets.
Yeah, those tie fighters are so loud, they are even loud in the vacuum of space !!!
Im not here now... Im out KILLING pepperoni
Nowadays, trains zip by cattle many times a day, and they don't even bother to look up anymore..
That's because when no one's looking they're standing up and drinking coffee. Cows. Is there anything they *can't* do?
Everyone has all of these theories on white noise and ambient noise and crap during the day. WRONG. I'll tell you the real reason. Train engineers are assholes. I lived next to train tracks for a few years and during the day trains NEVER wailed on their horns. But come night time those f'ers would just sit on the horn for miles. Maybe it's a safety thing, that at night drivers may be sleepy and need advanced warning for a train, but I dunno.
So keep all of your white noise theories and I'll keep my "train engineers are assholes that just want to wake up all of the sleeping people at 3 a.m." theory.
The Japanese don't really have battle robots and stuff like that.
But Americans sure do!

is a maglev train?
Going from South Dakota, to Indiana, to Arkansas
eeeeeeeeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaaahhhh hhhhhhhhhhhhhhheeeeeeeeeeeeeeeeeeaaaaaaaaaa
They have these white noise generators that help filter out noises in a cubicle farm, they work by disrupting all sound waves and getting them to cancel out.
No, that's just the air conditioner.
Disconnect your television. Do your own research. Draw your own conclusions. They're probably lying. Don't be a sheep.
Google is censoring this as it is deemed offensive by the maglev train manufacturers.
The one I liked is this story about one of the early prototype helicopters from Sikorsky landing in a farmer's field; it was just an engine, rotors, and skeletal frame without a proper cockpit or outer skin. This farmer walks up to the test pilot, and asks, "Did'ya build it yourself, son?"
I can't wait 'til one of the X-Prize guys lands in a farmer's field... "Do'ya come in peace?"
It's the noise of all my pots and pans flying across the room into the wall nearest the train when it goes by!
funny thing, Night Train always puts me to sleep. Or was that MadDog 20/20? Either way, I wake up in the morning with a splitting headache and I can never figure out why. Maybe it's that damn air-horn after all.
