Title: Hearing voices in white noise
Post by: m00k0w on 25 October, 2012, 04:21:05 AM
Every time I play noise, usually pink noise, I will hear what sounds like faint vocals behind the ripping fuzz of noise. Typically I am generating the file for system tuning, and the voices catch me off guard every time. I cannot make out any content, but there is a clear (usually) male voice, at times screams, laughs, etc. However, the vocalizations are not randomly hallucinated simply because there is noise present in the room. That is, I'm not crazy, I promise  If I seek to the same spot within the file over and over, the same vocalizations (tone, pitch) repeat, especially after some sort of notable colorful deviation from a comparatively monotonous mumble. I can seek to, and repeat this especially loud vocal over and over.

Is this the brain picking what it can out of a ton of data, because some parts or patterns at certain frequencies of the sound somewhat resemble voice? I'd like to learn a bit more on this, and know if anyone else readily experiences this. If you've never noticed this, I can generate pink noise and listen myself until there are some notably loud sounds resembling a vocal, and save these parts with a description of what it sounds like is being said or hummed. As I said usually I can't pick even a single word out, although it sounds like the vocal flows and modulates like a real person speaking would. Good to try to emulate to add vocals or interesting melodies to your own sound.

reminds me of when i was a kid watching the static of an untuned television, i could see whatever i imagined in there. kept m,e entertained when the television channels switched off every evening.

Would you mind uploading a short example of such vocal noise to the Uploads (http://www.hydrogenaudio.org/forums/index.php?showforum=35) forum? That description made me curious.

Please, do that - generate pink noise ang give us excerpts where you think you hear voices.
I wonder - what kind of pink noise generator do you have if it inserts voices and screams inside?

Either you system catches AM Radio (google for Logitech speakers and AM radio receiving), but you couldn't rewind it if that is the case, or you need some heavy medications, mate.
But if you have analogue pink noise generator and recording it onto DAT or whatever, you could be picking up radio somehow and recording pink noise with the radio signal.

http://en.wikipedia.org/wiki/Electronic_voice_phenomenon (http://en.wikipedia.org/wiki/Electronic_voice_phenomenon)

"Auditory pareidolia is a situation created when the brain incorrectly interprets random patterns as being familiar patterns."

This makes sense, it would have been an evolutionary advantage to find false positives (instead of false negatives) when looking for patterns.

"For example, believing that the rustle in the grass is a dangerous predator when it is only the wind does not cost much, but believing that a dangerous predator is the wind may cost an animal its life."

This can happen in eyesight too, where the brain is always seeking patterns and often finds one where there is none really.

I'm definitely curious for a few samples of this noise, and more importantly, the method by which this noise was obtained. Clouds are random, but we still see familiar shapes in them.

"Auditory pareidolia is a situation created when the brain incorrectly interprets random patterns as being familiar patterns."

This is also what I figured.

It would be like the auditory-sense of a similar phenomenon of endless accounts I have heard where people see "faces" in certain things they view. As a social human, I can accept that my visual senses are accustomed to seeing symmetrical eyes-nose-mouth, as well as being attuned to hearing sounds resembling oral language. It's "natural."

FWIW my wife and I just completed 9 days of hiking along Lake Superior. We encountered just two people on the trail during that time, going up to 5 days at a time without seeing another human there. My wife reported hearing undecipherable human voices on the trail. Obviously, there was no one there.  The background noise was pretty much wind and waves - more like pink noise, but you get the idea.

 Or EVP (http://www.spiritsociety.org/ghost.php?page=articles&article=evp1.html) (messages from the "spirit world").  ...I think maybe the ghosts should to get together with Dolby to see if they can reduce some of that noise!

Here's a fun example of audio pareidolia:

No, there's no voices in the pink noise.  At least, THEY don't want you to think so.

"You're just jealous because the little voices only talk to me"

I don't hear such voices, but i do remember that rumble of heavy machinery did produce a music for me (after some time) and it was hard to reboot that (unless leaving the place).

Easy to make fun of if you never experienced something similar  .
Apparently lots of people (think they) hear vague music- or voice-like sounds when in a noisy environment. For example in an airplane or a factory. When I use the vacuum cleaner I sometimes think I left the radio on, but when I switch it off this is not the case.
In this article (http://www.hearinglosshelp.com/articles/hallucinations.htm) it is called "Pseudo-auditory Hallucinations".

In 2005 (a guy named) Peter van Cooten made 3 (ambient drone) mixes that were played on Dutch radio (obviously in a program for experimental music), the middle section is exactly inspired by this subject (and where I found the above link in the first place).

Some years later he put them on his website, for reference I added the links (if you're not into ambient, don't bother listening, however the notes on part 2 are related to the phenomenon discussed here)

Happens to me, too. Sounds like someone has a TV talk show on somewhere in the house, but there was never any break. I used to have a noisy PC, and was hearing those voices in the fan noise. Turning off the computer stopped the voices. My new PC is very quiet, so no more voices.

Most of my experiences with hearing mysterious voices in random noise take place in the back woods or on wilderness beaches. Wind in trees and waves on a big beach from a slight distance are like spectrally shaped white noise.  Sometimes my wife and/or I hear faint unintelligible voice-like sounds out there and occasionally people show up but usually they never do.

I confirm the existence of such a phenomenon.
From my scientific research it appears that it is caused by the observer effect known from quantum mechanics.
Noise or other random sounds are to some extent reduced in the observer's mind to specific values of amplitude, frequency, waveform and duration.
As a result of the progressive reduction of sound superposition - it is possible to arrange a modulation resembling a human voice or other sounds.
Who is responsible for this process - I do not know (ghosts, aliens, multidimensional beings, UFOs etc ..)
The phenomenon itself is real, although most often it is a weak enough effect, that without careful listening - most people will hear nothing but noise.
I understand electronic voice phenomena in the same way.

I think the vast majority of time is that you're looking for recognizable patterns in white noise subconsciously and there's a small percentage of the time where you might actually be hearing something as well.  If you can, feel free to investigate the cause of what it might be.

People are very good at recognizing patterns, be it auditory or visual.

Often people seem to kinda recognize patterns in random data. Sometimes they that present as evidence, even.

Matt Parker - the Stand Up Maths guy - did a pretty interesting talk on that with the London Mathematical Society:
