Infrasound harassment.

Using High-Intensity Ultrasound For Electronic Harassment & Targeted Individuals Since the early 1960s, researchers have been experimenting with creating directive low-frequency sound from...Acoustic devices have been used for military purposes including to stress enemies, as an aid in interrogation, and to create "an infrasonic sound barrier". [8] The British Army used "Squawk Boxes" to emit ultrasonic frequencies causing various discomforts. [8]But back to infrasound. The “acoustic harassment,” the “surface harassment”, the harassment by bone conduction—call it what you will. I haven’t been calling it infrasound because I’m not sure. If I can, I’ll try to finish off a post that talks more about infrasound in the next week or two. And, whatever kind of sound it is, I’ll have a …A soft, low-frequency hum can be felt, not unlike the hum that comes from a refrigerator, only stronger and lower. You don’t hear it with your ears, you feel it with your whole body. Subtle, gentle, but certainly there. Now imagine the occupant of that garbage truck ever-so gently pushing the gas pedal down, so that the sound gets ever-so ...

The CEA dynamic infrasound pressure generator is based on a pistonphone concept [12] in which the volume variation of a sealed cylinder induces a pressure variation inside it. The front sealed metallic cavity is in a vertical orientation (374-mm diameter and 270-mm high). A device under test (DUT) and a reference microphone (Mic) are coupled …

Infrasound constantly surrounds us, generated naturally; wind, waves, earthquakes and by man; building activity, traffic, air conditioners and so-on. Low frequency sound is used by marine mammals to …Sound from ultrasound. Sound from ultrasound is the name given here to the generation of audible sound from modulated ultrasound without using an active receiver. This happens when the modulated ultrasound passes through a nonlinear medium which acts, intentionally or unintentionally, as a demodulator .

Infrasound is a low-frequency audible sound that is oftentimes below 20 Hz. Infrasounds can be caused by various sources, such as winds, storms, earthquakes, volcanoes, and even wind turbines. Moreover, some animals, like elephants, even communicate with one another through infrasound since low-frequency sounds travel …

Sound of sufficiently high amplitude can injure and even kill. Discomfort begins at 120dB, hearing loss at 130dB, physical pain and immediate hearing loss at 140dB, and difficulty breathing at 160-170dB. The lethal threshold is estimated at around 185-200dB. The ‘sound cannon’ was first trialled in 2009 at G20 protests and has since been ...

Sounds between 20 Hz and 20,000 Hz are considered within our normal threshold of hearing. Sounds below 20 Hz are called infrasonic sound or infrasound. Low-frequency infrasound at high dB can cause tremors inside our organs and it hurts! Sounds above 20 KHz—our upper range of hearing—are called ultrasonic.Electronic surveillance is a broad term used to describe when someone watches another person’s actions or monitors a person’s conversations without his/her knowledge or consent by using one or more electronic devices or platforms.

We propose three non-exclusive scenarios for the use of infrasound for navigation by birds as (A) beacons, (B) landmarks, and (C) gradients. We consider a hypothetical bird trajectory (in black) sampled at locations x1, x2 and the target at times 1, 2, and 3.Infrasound waves having high decibel levels may have several unique effects on the human body, as seen from the table (1) below. Its effects can be seen even from the reaction of the body to naturally generated infrasound like the kind observed in a tiger‟s chuffle and growl and also in the sounds made by lions, crocodiles and whales.-INFRASOUND HARASSMENT- I am a top floor apartment tenant currently going through hell.
