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.'"

      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.

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.

      Drug-related hallucinations are caused by overmatching - your brain matches every single interpretation that could possibly fit to the stimuli, rather than just the most likely as is usually the case. And sensory deprivation hallucinations are also caused by overmatching: lack of stimuli makes the treshold of matching be adapted lower and lower until it starts matching random noise in your neural circuits. In either case, your own thoughts - which normally help get more accurate matching by "priming" likely interpretations based on what you expect to see - are the only thing that actually has a pattern, thus you get a "trip": a procedurally generated stream of perceptions based on your stream of consciousness and a random number generator.

      The difference between a sensory deprivation trip and a drug-induced trip is that drugs typically also affect your higher cognitive functions, which can also be considered a perceptual system of sorts, one responsible for parsing more abstract aspects of reality (such as physics, economics, philosophy and so on). The combination of these high-level perceptual shifts - "cognitive hallucinations" - and a running illustration can lead to a very powerful psychological effect, which is why taking psychedelics in particular can be a life-altering event. And usually for the better, since your sober mind can analyze the experience and keep the grain and discard the chaff afterwards.

      Maybe longer would do it.

      Yep, longer will do it, I'd find it very difficult to believe someone can go without sleep for five days without hallucinating. I worked on a fishing trawler in the southern ocean. Every voyage lasted about 3 days. That's no sleep for 70+ hours, 30-35 of them working straight through to fill the hold, only stopping for 30 min every 5hrs to get something to eat, the other half of the time was normally spent holding on for dear life in the "roaring forties" between the Islands and the mainland

      Driving home in twilight on a country road after my first voyage, a row of white goblins suddenly ran single file across the highway, they were about 3 foot tall with one big red "Cyclops" eye that took up their entire face . They kept coming out of the thick scrub all in neat single file, every one of them looking straight at me, running for their lives and showing no signs of breaking formation even though I'm driving straight at them at 100km/h.

      I hit the brakes even though I kept telling myself in my head that it wasn't real, I hadn't yet realised I was hallucinating and could not work out what the fuck was going on, and whatever they were I certainly didn't want to hit them. I noticed that as I slowed down so did the "goblins", when I was nearly stopped I just as "suddenly" realised it was the row of white guide posts with the red reflectors that you get on hazardous stretches of highway. They appeared to be running across the road because I was approaching a long right hand bend. I hadn't been looking at where the goblins were going until I was almost stopped. What was left of my attention was focused on where the goblins were coming from. As soon as I looked to the left to see where they were going, it broke the illusion.

      It was only then I realised I had been hallucinating. Further down the road on that 30 minute trip I saw a large "beast" on a semi trailer. it looked a bit like an elephant or a hippo lying on it's back with it's legs straight up and in chains, before I could put a finger on what type of animal it was it morphed into a log truck carrying two stacks of short logs. A bit further down the road there was a (very fat) aborigine sitting under a tree at the side of the road sporting a loin cloth and yellow corroboree spots on his body, that turned out to be a large lichen covered rock. As I was showering and crawling into bed someone kept speaking my name every few minutes.

      I worked the boats for about 6 months (circa 1980), the goblins were the best but also the most disorientating. Once you realise what's going on and start expecting it to happen they don't seem to last as long or appear as frequently. Some people can sleep on a 60' fishing trawler in high seas, most can't, some of those (ordinary) people see really fucked up shit that stops them going out to sea again. Personally I quite enjoyed the audio and visual effects my brain throws back at me when it's protesting a lack of sleep. I can see why Alice was so curious about the rabbit hole, needless to say I got the wife to pick me up from the docks after that first voyage. I slept a solid 24hrs after every "trip", curiously about the same amount of sleep I had missed over the previous 3 days.

      The way I understand tinnitus, I don't think it would make a difference.

With tinnitus, however, some of these hair cells are damaged and can no longer detect vibrations. As a result, the accompanying neurons associated with those damaged cells become "hungry" for stimulation because the brain sends an increasing level of "outbound" signal since it never receives any "inbound" signal, thereby causing the ringing sound we hear...a "loop" of information, if you will. This is very similar to the phantom-limb pain we can feel after having lost an arm or leg; this situation also causes the associated part of the brain to stop receiving signals from the amputated or damaged limb and the increased level of outbound signal causes (severe, in many cases) pain. Tinnitus works the same way, but on a much smaller scale because fewer neurons are left wanting, plus we still have many hair cells remaining which function normally and help "drown out" the ringing.

      So, by that rationale I imagine that the ringing would be much more apparent initially but would eventually be drowned out by the sounds perceived by the working cells, like heart beat, breathing and digestion. Then when those sounds are not enough, our brain starts creating "phantom" stimulus which causes the hallucinations.

      In short, I would think the answer is no.

And can you talk? I would actually find it really fascinating, and not scary at all to hear my heartbeat and the blood rushing through my ears...

    I think I'd have fun in there.

  50. Rock can be a pretty good sound absorber, too... by Anonymous Coward · · Score: 0

    I've been in some old mines in the Mojave Desert that are every bit as quiet as one of those chambers. When you're with a group of fellow explorers the footsteps, chatter, everything is normal and familiar, but just stray away from the group a hundred feet or so and... total silence. It is very creepy and one of the main reasons (other than the obvious, such as if you got hurt you'd have no way of summoning help) that I'd never do such exploring alone.

    "Dig a hole about forty or fifty feet deep. Make a monolithic pour of waterproofed concrete."

    You're nuts. Do you realize how much it costs to dig a hole 40 or 50 feet deep? Big enough for a person?

    And there is no such thing as "waterproof concrete", especially at a depth of "forty or fifty feet deep".

    1. Re:Dig a Hole 50 Feet Deep? by Runaway1956 · · Score: 1

      No, there is no true "waterproof" concrete. But, you CAN choose mixes that are less porous than others. The average driveway is poured with 3000 lb concrete, which may or may not actually be 3000 pound if you have a cheat supplying the concrete. When the concrete arrives on site, it's usually watered down, making your questionable mix even sorrier.

      Specifying your mix to a high grade, then adding some good stuff tends to make the concrete stronger, more resistant to cracking and spalling, AND less porous. Less porous concrete will pass a lot less water, or none at all, depending on location, water table, and other minor details.

      Oh - digging a hole 50 feet deep can get expensive. It depends on whether you are following OSHA guidelines or not. There are a LOT of deep holes in this world that were dug before OSHA ever existed. My father in law dug a number of them. Ever heard the term, "Colder than a well digger's ass"? Admittedly, FIL never dug a well that was dug out at the bottom to create a larger room, or chamber, but he certainly dug some wide enough to provide room for a man to sit on the bottom in a nice cushioned chair. Maybe enough room for a very small end table to hold your beer, too.

  55. John Cage and an anechoic chamber by bfootdav · · Score: 1

    John Cage's experience in an anechoic chamber was instrumental to much of his thinking about music and silence. Or at least it made for a good anecdote that he used quite often:

    "There is always something to see, something to hear. In fact, try as we may to make a silence, we cannot. For certain engineering purposes, it is desirable to have as silent a situation as possible. Such a room is called an anechoic chamber, its six walls made of special material, a room without echoes. I entered one at Harvard University several years ago and heard two sounds, one high and one low. When I described them to the engineer in charge, he informed me that the high one was my nervous system in operation, the low one my blood in circulation. Until I die there will be sounds. And they will continue following my death. One need not fear about the future of music."

  57. noiseless vs. noise cancellation? by kencurry · · Score: 1

    My wife bought me noise canceling in-ear headphones; they work surprisingly well. I have found this to be a little disorienting when you do something like open a bag of chips and there is no external noise, but it seems like the bag-crinkle noise is conducted through your body and you sort of hear it inside your head - strange. Crunching is too weird, I have to turn them off. Great on airplanes and trains though!

    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.

    1. Re:Indeed by Anonymous Coward · · Score: 0

      First off, for all practical purposes, no vacuum chamber on Earth is fully devoid of matter, not even the vacuum in space which has orders of magnitude less stuff. Second, you can have temperature without matter, as a photon gas will also have temperature, and the only way to avoid that is to either have the vacuum chamber be at absolute zero or having a non-thermal equilibrium (but there will still be populations you can talk about the temperature of). Lastly, the only way you can have a vacuum chamber be essentially sound free, is for all of the particles to have a mean free path much larger than the chamber size, so that they are non-collisional and cannot effectively transmit any sound with a wavelength that could fit inside the vacuum vessel. Although keyword is effectively, as there is still some tiny, non-zero coupling.
