Acoustic Localization through wall/ceiling/floor

eavesdropping contact microphone oldie
eavesdropping contact microphone

These acoustic localization tools could be effective for locating people unobtrusively without breaching walls or ceilings. The only problem is that making noise would be hurting the listener, so the technology has to have some sort of limits on intensity/loudness/ etc. Another problem is that the listener would be listening to his own generated noise as well. Projecting noise onto the victim is complicated part too where everything has to work seamlessly.

What is the purpose of listing all of this? I guess one point I’m trying to make is that even if someone gave average person unlimited funds to organize such harassment it wouldn’t be feasible. It’s not so much about technology it’s about science of hurting people.

At the same time you never see any rescue teams using such equipment – they usually have them photographed climbing over huge piles of rubble and considering that there are lots of  equipment and people frantically moving around these acoustic tools don’t really make much sense.

At the same some slab leak detection specialists or as they call themselves plumbers appears to have tools that could also be used for eavesdropping and covert surveillance as demonstrated in this video: https://www.youtube.com/watch?v=iJO7K4kvPls

They also had neuroscience section full of devices to practice various psychiatric behavioral methods on rats.

nowadays they have section called “sensation and perception”, which makes me wonder if its achilles heel or something even worse than one could imagine.

I guess there could be possibility that they developing something along the lines of weaponized rabies that is achieved not through biological virus, but through neuro-psychiatric means. Who knows maybe they were successful driving mad animals and trying to replicate and fine tune the method in humans. Maybe biological warfare these days is something about switching 0 to 1?

These high-tech microphones operate by converting the imperceptible strains in a building partition created by nearby sounds directly into electrical signals. The tiny signals are amplified to a high level suitable for input to recording equipment, radios, or real time monitoring with headphones. Unlike conventional or under-door microphones, WASP2 mics do not require an opening or air-path to carry sound from the incident scene to the operator. Therefore, alerting the suspect by drilling a tell-tale hole, or otherwise exposing the operator to the incident scene is not required.

Each microphone is fitted with a 3.5mm mini-phone plug ready to work with most “mic-input” audio devices (audio recorders, radio, etc). Adapters are available for use with most Android or Apple smartphones and complete tactical audio kits, containing one or more WASP2 mics, a digital audio recorder, noise-isolation headphones and all mounts and accessories are available.

Covert through wall/ceiling video surveillance

I don’t think it would be wise to drill holes through ceiling or walls for the sake of visual observation as it leaves undeniable evidence behind. But for the sake of completeness I add these tools as well.

Near-Silent Drill (archive) Screenshot from 2015-05-05 17:57:14 1

*NATO STOCK NUMBER: 5130-99-235-4923* The operationally proven Near-Silent Drill has been refined and developed over many years of professional operational experience to produce an immensely powerful and near silent low noise drill. In a hostage or surveillance situation the Near Silent Drilling System allows audio and visual intelligence to be gathered without alerting the targets.The Near Silent Drill will successfully drill through a wide range of construction materials using the specially developed main drills for long access holes and pinhole drills for the final breakthrough. The main drill bits are diamond coated meaning that even the toughest of construction materials can be drilled successfully and when combined with the two 100mm extension tubes all but the thickest of walls can be drilled.The drill has a highly-geared near silent gearbox which allows one to drill at very low speeds. It is the speed at which one drills rather than the material being drilled which really dictates the noise of the operation.The Near-Silent Drill is mounted to the target wall using a base plate and adhesive or by securing it with a pin. Once in position the angle of drilling and the speed of the operation can be closely controlled. Unlike other drilling systems the unit does not have to be held in place by the operator.

  1. You have alot of pitures, but of the stuff they do not use.
    The good news is, that after 3 1/2 years of heavy torture, I have designed a shield that stops their infer red 3d imager, this can see thru every thing expect lead and all acoustical devices which can shoot thru anything unless placed in the correct order, that was the hard part. They are having a fit, they do not know what to do. Police harass me now daily too. It is a combination of aluminum, lead sheeting, acoustic absorbing material. Yes it is expensive to make, or ship to people. I am in the New Orleans La. Area. I have been sleeping 6, 7, 8, 9 hour nights for about 90 days, the first time in 14 years of police harassment 24/7, they can not use loud cars any more as the shielding absorbs all the noise. All of there tricks work, any longer, also stops them from making suggestions to you during rim sleep. HA !!HA!! No more. they follow me around like fools, I now laught at them, over a million man hours of harassment, shoot 300,000 times or more, a $1000,000 dollars spent. I won in the in.

    • How do you know what stuff they use? I listed stuff I speculate that could be used to accomplish effect of through wall localization as if person being followed inside of his apartment. What exactly is being used is subject of speculation. It’s not so much device itself that is interesting, but idea and it’s implementation. You can teach even a monkey to ride a skateboard, but to come up with idea of skateboard and to create it is totally different story. If you take millions of skateboarders that use it around the world i doubt many of them could recreate skateboard from scratch if given even unlimited funds.
      You make a mistake if you think it’s about winning. It’s a process of collaboration on one end based on some sort of idea used to rally support, while on another end it’s very ambiguous what a hell is going on.
