Silent Sound. New technology brings new dangers. You need to see what these new technologies can do. The police around the world tend to ignore complains about these new technologies as they are difficult to capture and proof, unless you are persistent and have the right tools. This is a serious matter because it involves tampering with your thinking. If your thinking can be tampered with then what else is there for your supposedly independent mind. I am fascinated with this phenomenon as it highlights the process of ownership of thought and the ideas you create. As an artist is my work my own. I am talking about this gadget and what it can do to alter your thinking without you knowing about it. It is a flat ultrasound speaker. What’s fascinating about this speaker is that the hardware (speaker) only hold the electronics for this design. The sound source and the speaker itself is created outside the speaker. The speaker projects modulated ultrasound into the air. The source of the sound is just in front of the speaker but the sound sound itself opens up in mid air. So your speaker is really located in space and in only one particular area depending on the direction the flat panel is pointing. How this happens is when the ultrasound (normally cannot he heard by the ear because the frequency is too high. The ear can only hear from 20 hz to 20,000 hz) interacts with the air as it is projected into space, it opens up and the frequency drops to the hearing range and it opens up to a lower frequency you get to hear it but when it opens up IT IS IN MID AIR and the sound feels like it is coming from precisely there – suspended in air.

Also the sound is not all around you but rather in only one place in the air – it behaves like a torch light, the sound is spotted but it can bounce off walls and gets reflected around a room. So it either creates repeated phrases in the space around you as it reflects off the walls creating a canopy of music or words in air which you might occupy. The volume of the sound can be adjusted from audible to hardly audible. Both these forms can have a sinister side to it if you don’t know what is happening when you hear these sounds in mid air. Here you can see the source of the sound is in front of the panel and the sound projects out like a bullet.  They come if different configurations and intensities.

It is when the level of sound is just at the edge of the threshold of hearing is when it is most dangerous.  It can then become a tool for conditioning of the mind and all unknown to the person.  The tools to fight this is lots of observation and the right tools to capture the ambient sound.  You will know how to do this when you know how it is designed and why and how it works.

       

Not many on the net who will speak of the down side of this phenomena. Below is one of them. ” As with almost any technology, in the wrong hands HSS and focused audio could be dangerous.  ….there are potential problems for everyday life”  Please also look at the link for this extract below for a good explanation on directional sound using ultrasound.

“It is not your imagination”

So if it is ultrasound that is involved in this gadget, then it is ultrasound microphones that you should use to capture these sounds.  I had a bat detector with me and some software.  People use it for capturing the sounds of bats which emit ultrasound.

Here is one of them but you can look at others here: http://www.durhambats.org.uk/reviews.htm

 

I used a relatively cheap ultrasound microphone called the  Batbox Baton. It comes with software and you can use your computer to record.

This is what I got:

I had edited this for line noise.

Here are different extracts I found on the net that could add to this article.  Here it is, “human ear is sensitive enough to hear 0.0001% of the energy”.  When a pressure wave falls within the hearing band, 20 Hz to 20 Khz, you will hear sound, (trigger)words, music etc, and this will create an emotion and it will start the thinking process.  If the pressure wave comes in under the 20 Hz or over the 20 Khz, you might not hear a sound, but the pressure waves will still get processed by the ear and when it gets to the brain it will trigger the thinking process.  There is bleeding of sound with with ultrasound outside the main beam: “In the absence of all ambient noise, complete silence outside the beam is impossible, as the human ear is sensitive enough to hear 0.0001% of the energy; but just as this is a non-issue with light beams, it is usually is not an issue with beams of sound.”  I think low level sound are not a no issue. They do get processed and unknowing to you triggers thinking.

“While not precisely zero outside the beam, bleed is extremely quiet, with sound levels dropping over 90% one step outside the beam. It’s best to use a lighting analogy: Our systems “shine” beams of sound onto a very specific area. Just like it is easy to see the light from the beam of a flashlight in a very dark room, it is sometimes easy to hear very quiet sounds in a silent room. Typical background noise helps to mask the bleed, just like ambient lighting makes a flashlight beam invisible unless it is aimed right at you. The dramatic drop in level should be plenty to maintain the quiet outside of the focused area. In the absence of all ambient noise, complete silence outside the beam is impossible, as the human ear is sensitive enough to hear 0.0001% of the energy; but just as this is a non-issue with light beams, it is usually is not an issue with beams of sound.”

But in most of these cases of  shenanigans using ultrasound speakers you will hear a low muffled sound that emanates from space as explained above and also is so in reality.

here is another extract;

“The Holosonic® technique for sound generation in the Audio Spotlight is a fundamentally different way of creating sound, and is not limited by the barriers facing traditional acoustics illustrated above. This is because the source of sound from an Audio Spotlight is not the physical loudspeaker panel – it is the volume of air in front of it. This makes the actual sound source far larger than the physical loudspeaker seen – it just happens to be invisible, and made from ultrasound. This enables the Audio Spotlight to fundamentally provide far more directivity and isolation than any loudspeaker can ever provide.”

Ultrasound is only one of the tools to create low level muffled sounds in the air to manipulate thinking and perception.  Sounds directed down drain pipes in tower blocks or shared premises will almost create the same effect. Vibrating speakers behind walls could also do the same.  Hidden speakers behind partitions, but here you know that traditional sound has not got the same characteristics or feel of ultrasound speakers.  Traditional speakers are more physical in nature.  Ultrasound speakers are design to make the air around you to act as speakers and they have a sense of invisibility about them. They appear and vanish in mid air and is difficult to locate but not impossible. Better you know than not because it is here now to haunt you if you do not know as technology has done it again and given us a new problem.

With these 2 examples below under normal circumstances  I could not hear any of the recordings below.  Only with the microphones below will I be able to locate the music in the air.

I used a ultrasound speaker that projects sound into the air as I had explained above.

In the first example I recorded the ambient air using a parabolic microphone: you can click on the image to see detail.

You have to use in-ear headphones for best results because remember that here i am trying to capture sound that your ear cannot hear but is present in the air and you can hear it when it is amplified.

So you can see with this ultrasound speaker that there are certain areas in the air that are amplified and others are lower in volume.  I think this is because as the sound bounces off the walls they create standing waves and where they meet they cancel each other out.  The speaker itself would create a location in front of it in ambient air that has the loudest volume because that is how it is designed.  This is about ultrasound and ultrasound speakers creating sound in mid air.

This 2nd recording is interesting as it shows up some other aspects of this speaker.

It was recorded using an ultrasound microphone:

You can see with the recording above that the music is accompanied with a tone. As I have noted above this is why with these type of shenanigance you get a high level of tinnitus in your ears but there is one important aspect to this tone.  It will show you clearly how the canopy of ultrasound emitted by the speaker is created in a room. This recording below was made using the parabolic microphone.

The importance of the above is that you might not hear it because the frequency of the pressure waves created is too low and hence there is no sound created in your ear/head but when amplified you hear it.  Also this means that if you don’t hear sound that does not mean there are no pressure waves in the air and these low level waves will still get picked up by your ears and will alter your thinking if it is a trigger word, alter your perception and your emotions as a result – and you won’t know why.  Ultrasound with its property of creating a  pressure wave canopy in mid air from the ultrasound speakers has a hackers delight in getting into your mind.  If you follow the line of the tone in this ultrasound canopy of modulated pressure wave/sound with your parabolic microphone you never know where it will take you.

The MIND today is hackable.  Thinking is no longer off limits. Ideas and perception might not be your own anymore.  The mind that created the troll is now being attacked by its own creations.

Sub vocal speech is that where you silently speak when you think.  You are wired that way. Now if you can monitor this sub vocal speech then one can know what you are thinking.  The design of the parabolic microphone is such that it keeps the noise level of the recording to a very low level.  So to demonstrate that sub vocal speech can be captured this would be a good microphone to use.  I have used a relatively cheap parabolic microphone and recorded my inner sounds to demonstrate this phenomena.  If you were looking at me you would not have thought that I was saying anything. You will notice how easily it is to hear your breathing and i was “thinking” “jack and jill……….” silently.  “Speak Thinking” has been a favourite interest of mine. If another can know what I am thinking then what else is there?

Click on image to see detail. also use in-ear headphones if possible to hear recording.

Just making sure that my work is my own.
