The Quietest Place On Earth Will Cause You To Hallucinate In 45 Minutes
Hugh Pickens DOT Com writes "Industry Tap reports that there is a place so quiet you can hear your heart beat, your lungs breathe and your stomach digest. It's the anechoic chamber at Orfield Labs in Minnesota where 3ft of sound-proofing fiberglass wedges and insulated steel and concrete absorbs 99.99% of sound, making it the quietest place in the world. 'When it's quiet, ears will adapt,' says the company's founder and president, Steven Orfield. 'The quieter the room, the more things you hear. You'll hear your heart beating, sometimes you can hear your lungs, hear your stomach gurgling loudly. In the anechoic chamber, you become the sound.' The chamber is used by a multitude of manufacturers, to test how loud their products are and the space normally rents for $300 to $400 an hour. 'It's used for formal product testing, for research into the sound of different things — heart valves, the sound of the display of a cellphone, the sound of a switch on a car dashboard.' But the strangest thing about the chamber is that sensory deprivation makes the room extremely disorienting, and people can rarely stay in the dark space for long. As the minutes tick by in absolute quiet, the human mind begins to lose its grip, causing test subjects to experience visual and aural hallucinations. 'We challenge people to sit in the chamber in the dark — one reporter stayed in there for 45 minutes,' says Orfield who says even he can't stand the quiet for more than about 30 minutes. Nasa uses a similar chamber to test its astronauts putting them in a water-filled tank inside the room to see 'how long it takes before hallucinations take place and whether they could work through it.'"
Cool, a real geodesic psychoisolation chamber
Some people [pointedly looking at neighbors] need external sounds to mask the quiet in their heads. The quieter the head, the louder the noi^Wmusic.
Free, as in your money being freed from the confines of your account.
Hmmm give me some booze and a bucket. I bet I can beat that
I've spent over an hour in a sensory deprivation tank and it wasn't nearly as trippy as this makes is sound.... Maybe longer would do it.
I've been in an anechoic chamber - it is quite strange, when you talk it feels like your voice is being sucked out of you.

And people who are deaf are all out of their minds?
No wonder deaf people are always flailing their arms at each other. It all makes perfect sense now!
Not having reached the point that I can ignore all external stimuli, that sounds like a place I could work on inner stillness, at least. Too bad it's so far from where I live; I'd like to try a few individual hours.
it's looking into the future
With this condition you will always be exposed to some other forms of sound - would this prevent the hallucinations?
After all, your senses are not fully deprived of input.
The saddest poem
You can still hear, though. Sound waves can travel through your nose and mouth, and through your bones. In that room there's no sound, at all. Anything you hear will come from inside your own body.
I wouldn't last more than a minute there, though. I become anxious within a few minutes of wearing earplugs, and I need them to swim underwater.
I think they just found a new enhanced interrogation technique.
A new one, hardly. They've been using it for 50 years. http://www.salon.com/2007/06/07/sensory_deprivation/
Given all the vacuum chambers on earth I also doubt it is the quietest place on earth. The quietest with air perhaps but not necessarily quietest overall.
It's $300-$400 per hour—the real reason nobody can stand to be in for so long. You have to get out early before they charge you for the next hour.
Sadly not surprising. Hell, I believe even solitary confinement should be tossed out as a form of psychological torture.
I stole this Sig
Are you sure that deaf people don't hear ANYTHING? Or, maybe they simply can't hear the same way you or I do?
I know for a fact that deaf people can sense vibrations, and sound is nothing more than vibration. Your ear is specially designed to make sense of a particular type of vibrations.
What about bone induction?
I googled "hearing without ears" and got a boatload of hits. Some look pretty interesting, some look less interesting. Try it yourself.

Dig a hole about forty or fifty feet deep. Make a monolithic pour of waterproofed concrete. Install the insulation and the anechoic surfaces. You'll want at least a couple soundproof hatches in the access tunnel, maybe three or four, to eliminate noise from the wind or whatever.
With your own chamber in your back yard, you can deprive yourself anytime. When you tire of that, you can use it to hide your armory, or your gold, or dead bodies. Whatever needs to be hidden, you've got the place to hide it. Plan for the future though - a guy never knows just how many people he might meet who desperately need to be bludgeoned to death!

It isn't being advertised as a "sensory deprivation chamber". It's being advertised as a sound testing chamber. You are deprived of one sense, and one sense alone, in this chamber.
Phhttt.....

Not what it says. It says when it gets THAT quiet, and you start hearing your own bodily functions, like (i.e., heart beating, lungs processing air, blood rushing through veins) that it tends to mess with your head. Deaf people, by virtue of being deaf, hear none of those things.

It would be interesting to see the reaction of a competent yogi in there. They study exactly that: excluding sensory input and generating alternate mind states.
It's not exact, but I did run across an unusual and unlikely method of simulating the sensation. In high school I was helping make props for a play. We were coating party balloons in paper mache. After it had dried a bit, we popped the balloon and removed it. As a joke, one of us held the hole up to our ear, half expecting to "hear the ocean" like you do from a seashell. The result instead was silence and a feeling of low pressure, as if your eardrum were being sucked out. It wasn't just me either - everyone who tried it reported the same sensation.
Years later when I went into an anechoic chamber for a hearing test, I recognized the same feeling. It isn't "silence" like when you're in a quiet room. The minute echos tell you you're still in a room. It's more like an open emptiness, with a similar feeling of low pressure against my ears. Close your eyes and you can't tell you're in a room.
I think the low pressure sensation is psychosomatic. When you ride a plane, the pressure change mutes the sounds you can hear as well as puts pressure on your eardrum. The quiet of the anechoic chamber or the paper mache balloon is very much like the muting of sound you get from a pressure change. And I think the brain automatically concludes you must be experiencing a pressure change, and makes up the sensation of low pressure.
I had a go in the UK Plantronics anechoic chamber last year on a factory visit. They have a webcam, and an egg timer on the wall. It's not odd for people to weird out if they spend any time in the chamber. The (digital) egg timer was there so you could set it for 30 minutes and it would hopefully snap you out of any spin you got yourself into.
I was in there for no more than five minutes, and it was extremely disorientating. You really can hear the blood in your ears. It's very much like the sound you get from sea shells. I can easily imagine losing my shit in short order in there.
yes, www.dotcomforwardslash.com is my real URL.
Tinnitus is no fun in low noise environments as your ears seem to be awash in it. It seems really loud and overbearing, since it is all you hear. That kind of thing happens when you get your hearing tested and you have it (as I do). When they start doing threshold of hearing tests and the sounds they make are really quiet, the tinnitus seems massive and overpowering. Then you take off the headphones and leave the booth and it vanishes.
That's what she said...
...ever gone into the anechoic chamber, on weeeed?

What you're failing to see is that if you spend decades adapting to a world of sounds, having that yanked away will fuck you up. Most deafness is either congenital or progressive, so it's either all you know or something you adapted to. If you look at cases of people who are suddenly deaf, you'll find similar problems adapting.
By the same token, people who were deaf who through new surgical methods are made to be able to hear, actually have a very hard time adapting to it. We who can hear take for granted the period in infancy when we develop the mental capacity to reflexively filter out background noises and such. People who were deaf lack the automatic mental controls, and in a sense, can't stop hearing, which makes it hard for them to focus on specific sounds (and hard to sleep). It's so bad that some even have the surgery reversed and voluntarily go back to being deaf because to them it's better than a sense of hearing that they can't control.

Back in the 90's I spent some extended time in a sensor deprivation chamber.
Nothing as fancy as this place. Not even remotely close. Just a salt water tank and a really really dark and quite environment.
I can tell you I was Hallucinating in far less than 45 minutes when I was in a sensory deprivation tank. Auditory hallucination was the first. Then physical sensory. Then finally visual. I can't comment on temperature. I had no memory of anything to do with temperature. Pain was there, but I am a bit confused if it was a memory of a memory or if I actually felt in while in the tank.
I was in their for about a week. It was suppose to be longer. But I got pulled out when people got worried. Apparently I was not exhibiting an EEG with in expected norms. What ever that means. I used to know more about the results. But that was 20 years ago.
The hallucinations got so intense that I believed them. This only took a relatively short time. No way of telling how short really. Nothing really weird, or dangerous. I substituted what I believed to be a real world environment. Yes responses from others were to easy and terse. Which was odd. The most unusual thing was travel. Traveling distances took little time at all. Rather I don't remember details of travel. Things that you would normally remember. There is always something about a journey you remember. In the tank I didn't have those memories. I always felt rather dis-connected after travel in my hallucinations.
I was completely freaked out when they started to revive me. They started with light and then some sound in the tank. Apparently I resisted it. I forced my eyes shut and made funny faces when the light and sound started. It really was hard to accept my environment. It felt like it all went down in a few minutes. But apparently the process was over an hour.
What you do for a little Uni cash.
PS. Yes they hooked up tubes to my bits. That was more disturbing coming out than in. I'll never forget that.
A while ago 5 years now.. (how time flies) I ended up travelling across Eurasia on a motorbike. Passing through desolate areas like Kazakhstan and Siberia away from the railways would be a spooky experience. You'd put your tent up and it was so quiet you could hear your heart beat and your tinnitus. You would always think though that somebody was sneaking up on you and would stab you to death and rob you.
I don't have to go to a special chamber to hear MY bodily functions.

I thought this would be discussing my bedroom. Not much happens when there's a baby sleeping in the room across the hall.
"Action without philosophy is a lethal weapon; philosophy without action is worthless."
Having worked in a decent recording studio, absolutely not.
A good studio has little echo, but still some. A missing echo makes instruments sound like they're synthesized; especially percussion and hammered strings. When people hear a drum beat, the first thing they get is the loud thump as expected, but that's mixed with an echo a few milliseconds later as that thump bounces off the walls and ceiling of the studio. While humans can't really perceive the echo as a second drumbeat (because they'll also be hearing the drum head still vibrating from the initial hit), the extra echoes add complexity to the wave, making the drum sound more vibrant.
Without echoes, everything sounds dead, much like a digital sample that's been compressed too heavily at too low a bitrate. Sure, there's a drum, but it's not quite as good as a real drum. There's a singer, but they sound like they're talking more than singing. About the only instrument that sounds right is the electric keyboard, but that's not much of a song. This is actually one of the reasons that recordings made outside sound different. There are no nice walls to brighten up the mix. A good recording engineer can then add echo while preserving the wind and ambiance, so the final copy still sounds like an outdoor recording, but the band sounds natural.
You do not have a moral or legal right to do absolutely anything you want.
It is really interesting that in absence of auditory and visual sensory input, the brain quickly fills the void with false experiences. It could just go into quiet mode instead. I like the idea that all of what our brain does is building a representation of our environment and trying to anticipate inputs based on this "simulation".
The solitary confinement scene in the movie "The Hurricane" gives a pretty good rendition of what it is like to go "stir crazy". If you want to try it out yourself just stay awake for 2-3 days. Weird sensation, you know the sound or vision is not real but it just won't go away, the visual ones are usually a real object that looks and "acts" like something else, usually something bizarre or impossible. Most of mine have been more comical than horrific, some can be downright helpful such as the "angels" who flew along either side of the wife's car, tapped on the window, and gently reminded her to open her eyes when she was nodding off at the wheel.
Hallucinations are normal, some have more than others. Probably the worst thing you can do is treat them as an illness (or demon).

Now now, relax, being curious about something is not the same as how you interpreted it.
I think he meant that he would love experience the room, not being deaf.
If he did mean being deaf "Do not attribute to malice, that which can be adequately explained by stupidity".
This is the sig that says NI (again)
Love to experience it? Just no. Imagine going to an interview for a job you really, really need - young family depends on you for food and shelter - and you can't even understand the small chat from the interviewer - "How was the trip here?" "Um, I... I... didn't understand the question, sir." "Oh, uh, never mind. Wasn't important." - let alone the substantive parts. People constantly think you're "stupid" because you're missing a source of input. You're never a part of a conversation; if you're lucky, someone will give you bits and pieces afterwards. You see everyone laughing, and maybe the joke wasn't that funny, but you never get to be a part of it, and if someone does bother to sign it to you, after the fact, it loses a lot in the retelling. Holiday get-togethers become the most dreaded occasions of the year: the isolation effect is amplified, and you end up playing with the dog, instead. You put your child down for a nap, and he ends up crying for 45 minutes, right in the next room, because you're busy working on something, and don't hear him. And on and on. Again, just no.
When I lost my hearing at 17 from spinal meningitis, I was out for a week - lost consciousness from the pain and nearly died - and when I woke up, it was just tinnitus. I saw people moving their lips, so I knew they were talking, but no sound. It was weird, but I got used to it quickly enough. What took longer to get used to was the social isolation. Though not intentional, I basically lost my friends. Only one person in my group of school friends bothered to learn sign language to communicate with me. Only one family member out of seven bothered to learn sign language. Two others tried, but butchered any attempt at it. Really, it's not that hard to learn or use. Lack of sound - not a big deal. Lack of communication? Much bigger deal.
When I got my cochlear implant, we worked on improving the sound quality for a period of about six weeks, and at the end of the sessions, my hearing was about as good as I remembered, except in noisy situations, where comprehension drops greatly because I don't have the filtering ability anymore: it all comes as one block of sound and the CI can't adapt like our brain does, automatically. Other than that, I had no problem adjusting to hearing again. In fact, it was like a new lease on life. But, I know of congenitally deaf people, as you describe, that reject CIs because they don't know what to do with the new sensory input. That, plus growing up deaf, learning things through sign language instead of speech, it makes it a bizzaro world transition: they don't know how to handle our "normal." I feel bad for those folks.
I had a small computer room lined with Armstrong's 'Soundsoak' panels and before the equipment was installed, the effect was stunning. I found the silence to be literally painful to my ears.
There is actually no temperature in a vacuum. That is assuming that one is speaking scientifically in that a vacuum is an absolute lack of matter in a certain volume of space. It would not even be described as absolute zero, because without any matter what temperature could you measure? On the other hand, if you're talking about a vacuum as in the thing that sucks crap out of your carpet, then yes it has matter and therefore would have a measurable temperature.
But the rest of your office mates desperately wish that you would.

No, that doesn't work. Too much information is lost. Unless you have a very narrow range of guesses of what they might be saying, you have no chance of understanding.
