Without visual stimulation, you also hallucinate. If you stare at yourself in the mirror in a dimly lit room, you will hallucinate and see terrible things within 10 minutes. All the participants who did this in a psychological study experienced these hallucinations.

I'm going to do this, what do you recommend for the "dim" lighting. I was thinking like 1 christmas light hanging from the ceiling?

Wow, I got it pretty fast. I'm at a university, and I can access papers free. Try the original publication here: You need to login to view this link but if that doesn't work, go here: mindhacks.com/2010/09/18/the-strange-face-in-the-mirror-illusion/

Good idea. Keep me updated! I hallucinate all the time at night, and don't want to do it in the daytime as well. I suffer from hypnagogic hallucinations.

Let me try to find the original research paper, or at least a description of the research. I found it a year ago, and don't have it bookmarked.

Alright, let me know if you do. I was just thinking maybe I'd use a strobelight instead, maybe that would make it worse/better.

So apparently you'd need a 25 watt bulb (incandescent), and be about 40 cm (16 inches) from the mirror.

You're the only one still here, so here goes. I stood there, dead still, for about 15 minutes (I set a timer) And I really started seeing some ****** up ****. First of all, after a while it looked like there was no light at all even with the dim light behind me. Second, I genuinely couldn't see myself in there. I became a sort of black silhouette with weird grey eyes, and some kind of elderly face. I really wouldn't recommend trying this.

tl;dr I saw an old person with grey eyes staring at me

I'm pretty sure decibels work on a logarithmic scale. Meaning that the greater the magnitude of the negative number, the closer to 0 on an absolute scale.

IE: -20 db = 0.01

how is something minus decibels

can you hear better or worse?
does it suck sound out the room?
and what would happen if you put a deaf person in there?
#159 to #145 - bluelips
Reply +3
(05/19/2013) [-]
it's not about hearing better or worse, you have the sensation every single sound (like your own clothes) is really really loud because your eardrums aren't experiencing everyday noise (there's reeverb everywhere) so they become really sensitive towards even the lightest sound. There are some people who experienced a rain like sound, it is supposed it was the air molecules hitting the eardrum. Pretty amazing stuff can happen in the anecoic chamber.

The walls are made of materials that entrap the sound within them, so they don't have any reeverb at all.

Also you can't just exit the anecoic chamber and simply enter a normal chamber because of the difference of sound between of them. This could lead to the rupture of the eardrum or even death, so there is at least another chamber in the middle, a sort of decompressing chamber.

This type of chamber is mostly used to test accurate loudness of things (for example vacuums before they put them on sale).

Hope I was helpful =)

not really    
   
i didnt know some words: reeverb and anecoic for example    
   
also does that mean negative decibels are louder than positive since you hear everything louder    
   
i never heard my clothes make any for om noise. and how does air bounce of your ears? i can understand the blood flow.    
   
if you fart can you hear the vibrations or the *plop*?

You don't have a face in negative sound?

Anyway, every ten decibels is percieved twice as loud as ten before it. Really -9 is about half as loud as 0, or a quarter as loud as 10.

it's actually ten times, not two. so, it's about 10 times quieter than 0 db, and 100 times quieter than 10 db

no, it's twice.
Every increase of 10 dB is perceived as the sound being twice as loud.

If a sound is 10db, you won't be able to hear anything below that.

So, if the room is recorded at -9db, you can hear everything.







(...Except for sounds lower than -9db)

Since the sound power level is:
P=10*log(multiplier) ---> multiplier=10^(P/10), where P is the decibels and log is decimal logarithm. In this case:
multiplier=10^(-9/10)=0.126.
That means that in that room, the sound power level decreases to 12.6% of the original value.
