long range acoustic device effects

Spot on with this write-up, I really think this amazing site needs a lot more attention. All Rights Reserved. Sonic weapon system. Are beta brainwaves the cause of schizophrenia? You see, the Vietnamese people worship their ancestors and they take a lot of notice of the spirits and stuff like that. Digital Justice visits LRAD (Long Range Acoustic Device) headquarters to test out its product. It has been hypothesized that body resonances, such as the abdomen at 10 Hz and the chest wall at 60 Hz, could be stimulated by high-intensity infrasound.72 Unlike other investigators who suggested detrimental effects of infrasound, Arabadzhi73 hypothesized that infrasound of moderate intensity at frequencies of 8 to 13 Hz could promote maintenance of a human's state of alertness. In addition to journal articles, books, and book chapters (i.e., “publications” as strictly defined by Easterbrook et al.3), items from the so-called “gray literature”4 (such as abstracts, proceedings of meeting presentations, conference reports, technical reports, patents, and official government documents) were used for this review. Experiments were performed at the Air Force Research Laboratory to determine whether narrow-band, high-intensity, acoustic energy in the audible frequency range could be used as a nonlethal weapon.79 Four acoustic devices were tested, (1) a compressed air-driven siren (Scientific Applications & Research Associates, Inc., Cypress, California), (2) a combustion-driven siren (the dismounted battle space battlefield laboratory) (Scientific Applications & Research Associates, Inc.), (3) an impulsive acoustic device (the sequential arc discharge acoustic generator) (U.S. Army Research Laboratory, Adelphi, Maryland), and (4) a complex waveform generator (the Gayl Blaster, U.S. Army Armament Research, Development & Engineering Center, Picatinny, New Jersey). 79) have shown that the weapon capabilities of audible sound generators have been grossly overstated. Found inside – Page 13... of the newness of new media taking its novel effects. for Michael Godard, ... such as the “Long-Range Acoustic device” (LRAd), or “sound cannon,” an ... Visual imagery relates to the brains association between a certain sound and a visual image or sensation. The Applicability of Acoustic Energy as a Battlefield Weapon. From the curators: Acoustic Hailing Devices (AHDs) are specialized loudspeakers that emit high-power sound waves enabling clear communication at long distances. However, it is in fact discussed by (L. Fannin, Ph.D, no date) that the effect of BWE on frequency ranges that are already heightened within our brain is what causes a negative effect. The mechanism of these effects could be a change in the activity of the labyrinth and/or otolith organs. On the Compound Security System’s website, who are the company behind the M.A.D, they specify that the sine wave frequency played by the device, at 20kHz, can only be heard by those under 25 years of age (Compound Security, 2015). As early as World War 2, we see strong evidence for the the deployment of sound, used in order to effect the psychology of enemies. But unlike mass-produced loudspeakers or other mobile media, this “sound cannon” is a niche device specifically developed for the U.S. military and law enforcement agencies. But it's not limited to producing painful noise for use as a weapon. The Long Range Acoustic Device ( LRAD) is an acoustic hailing device and sonic weapon developed by LRAD Corporation to send messages, warnings, and harmful, pain inducing tones over longer distances than normal loudspeakers. LRAD systems have been used to counter piracy, as non-lethal crowd control weapons, and as communication devices. Found inside – Page 166The effect can be generated by the extreme low frequencies in church pipe organ ... The LRAD - RX uses directivity and focused acoustic output to clearly ... Next, the Long Range Acoustic Device (LRAD) is capable of transmitting an intensely focused beam of noise directly into their ear. The effect of sound on our brain often leads back to a common theme of resonance. p> What is that thing this NYPD officer is carrying today? Subliminal Messaging. Presented at the National Defense Industrial Association's 5th Annual Security Technology Symposium and Exhibition, Group II: Security–Related Research and Methodology, Music: a new cause of primary spontaneous pneumothorax, NIJ's less-than-lethal flash-bang round project, Three dimensional sound and vibration frequency responses of the sheep uterus, Handbook of Sensory Physiology, Vol. (Walonick, 1990) reports in a experiment that below 8Hz had caused agitation and uneasiness for participants. In a gesture toward transparency, the company website lists its customer sales to 70 of the 190-odd countries in the world, while its media section now includes both positive and negative coverage of the LRAD. However, the LRAD—like other controversial military devices such as sound bombs and drones—remains a disputed technology. We sell those to the military presently for about 70,000 dollars, and they’re buying them as fast as we can make them.” (Norris, 2004). In the case of urban centers, the perceived disruption of social protest to the public order—and, by extension, commercial activity—is supported by the reported deployment of LRADs as a means of crowd dispersal. Our internal organs (heart, liver, stomach, kidneys) are attached to the bones by elastic connective tissue, and at low frequencies may be considered simple oscillators. We do know, however, that high- intensity infrasound causes headache, fatigue, and anxiety . The Long Range Acoustic Device is a creation of the American technology Corporation that was originally designed to defend safe zones around boats. However, though it is well documented that music and sound has been used within interrogation scenarios, this perhaps does not allow us to have an understanding of how sound effects our brain, as one can associate it’s effect as more physiological, due to sensory depravation caused, as a pose to psychological change. Report DRA/SS(PS)/CR96039/1.0. It has often been suggested that infrasound generators could be powerful enough to trigger nausea or diarrhea.42 Acoustic systems using infrasound could, in theory, cause a loss of muscle control or unconsciousness.43 Exposure to 16 Hz has been presumed to “make people feel nauseated and disoriented.”44 Remarkable properties have been attributed to infrasound, including the capacity to “debilitate people for hours and even days,” with “pulsing in their internal organs and blurred vision, both of which can lead to …, in rare cases, death.”45 Thomas46 reported a claim in a Chinese military medical journal47 that an infrasound weapon had already been developed and tested and that the device was adjustable, to cause controllable amounts of disorientation, nausea, vomiting, and incontinence. A review by Pawlaczyk-Luszczyńska87 reflects the lack of studies of infrasound at high intensities in more-recent years. Referring back to the use of 7Hz frequency, additional support is gathered with many texts referring to resonant frequencies within the body, with the likes of (Broner, 2003) stating “…it has also been alleged that this is the resonant frequency of the body’s organs…”. It was later admitted that this “weapon” was a hoax36 and was simply “disco gear” mounted on two armored personnel carriers.37 In addition, Rehn and Riggs,38 after performing a literature search, could find no data to support the earlier claims of effects. In this case, however, a lack of understanding of the physical principles could lead to the premature development of “prototype weapons” before testing or even reasonable consideration of such principles has occurred. Now you’ve got to understand the Vietnamese way of life to realise the power behind Wandering Soul. Found insideThat's why millions of dollars have been spent to analyze the effects of ... —also called a long-range acoustic device (LRAD)—that could incapacitate or ... The LRAD plays into such developments—even the briefest online research references the impact of the device on insurgents (often implicitly referring to the Middle East conflict), who put their fingers in their ears rather their using their weapons. “Non-lethal” weapons: precipitating a new arms race [editorial]. (Vinokur, 1993), “. Johnson123 stated, “… infrasound is an overrated phenomenon as far as some authors would have you believe. This device, known as the ‘Wirbelwind Kanonew’ , is perhaps the only known fully developed infrasonic weapon created in order to physically effect it’s target, with the intention of countering enemy aircraft and infantry by creating a vortex of sound (Crab, 2008). That’s when we come in and talk to them.” (BBC, 2003). They are linked to increased stress, which is why it is important to learn how to shift your brainwaves when needed. Kjellberg and Wikström71 reported that stomach motility in humans is affected by whole-body vibration (at 3 Hz and 6 Hz), as measured by electrogastrography. ‘Hypersonic sound’ can be referred to simply as the focusing of ultrasound. Voice to Skull directed acoustic devices are neuro-electromagnetic non … Foreign and Commonwealth Office, Department of Trade and Industry. Modeling Sound as a Non-Lethal Weapon in the COMBATXXI Simulation Model. “Body resonance” could be important in correlating the mechanical amplification of vibration in various parts of the body with physiological responses; that is, different parts of the body are in resonance at varying frequencies.69 For example, Von Gierke and Parker70 reported that human thoracoabdominal viscera exhibit resonance at 4 to 6 Hz. We can also note examples, during World War II and the Cold War, of experiments with ultrasonic and infrasonic weaponry in the context of military research and development. “It felt like my head was going to pop,” Neef recalled. Despite this, with adequate funding and electrical-engineering knowledge, it is possible to supply enough power to a compact device like LRAD that utilizes infrasonic frequencies to impair the enemy. We listen. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. The LRAD focuses a directional 15° to 30° beam of sound between 1kHz and 5kHz reaching a distance of around 5,500 meters (LRAD , 2015). In general, levels of >90 dB may be aversive to mammals and cause startle responses.82, It is important to note that the effects of audible sound cannot always be differentiated from those of infrasound.83 Infrasound may be audible to humans at sufficient intensity, but it is also easily masked by sound at higher frequencies.84. LRAD systems produce much higher sound levels (volume) than normal loudspeakers or megaphones. Infrasound is generally defined as sound below 20 Hz. This page describes some very unique items generally categorized as "ultrasound" The ultrasonic receiver is a device that can detect sound waves that are normally beyond the range of human hearing, and then translate this signal to audible frequencies. Such an event, however, was not reported in the article. Items were identified from the following electronic databases: National Library of Medicine PubMed (including Medline), Biosis, Embase, Toxicology Literature Online (Toxline Special), Developmental and Reproductive Toxicology/Environmental Teratology Information Center database, Agricola, Inspec, JICST-EPlus (Japanese Information Center for Science and Technology), Pascal (Institut de l'Information Scientifique et Technique, Centre National de la Recherche Scientifique), CAB Abstracts, Chemical Engineering and Biotech Abstracts, Life Sciences Collection, SciSearch, National Technical Information Service, Applied Science and Technology Abstracts, Academic Search Premier, Master File Premier, PsychInfo/Psychological Abstracts, Aerospace Database, and Online Computer Library Center FirstSearch (including General Science Index, Applied Science and Technology Index, Electronic Collections Online, and ArticleFirst). Moller101 also suggested that extra-auditory effects of infrasound “seem to have been exaggerated.” Bunker126 noted that the alleged effects of infrasound for use as a nonlethal weapon have been questioned because of contradictory evidence presented in previous reports. We use only the highest quality boxes and seal all corners and seams to reduce risk of water/liquid damage during transit. 22 long-range acoustic devices by a defendant upon another person is justifiable 23 only when: 24 (a) The defendant is authorized to act as a peace officer; and 25 (b) The defendant reasonably believes that such force is necessary to protect 26 another person from … The Long Range Acoustic Device (LRAD) was developed by American Technology Corporation (Now Genasys) and is a popular crowd control tool used by government agencies, law enforcement, and marine companies worldwide. There was no evidence of incapacitation induced by the acoustic energy per se. Whether exposure to such infrasound can trigger epileptic seizures, as some fear, remains unclear; experimental data on exposure to such frequencies gives a variety of results. Some investigators have suggested that infrasound can directly affect the vestibular system, thereby inducing vertigo and, potentially, motion sickness (see articles by Harris et al.62 and Von Gierke and Parker63 for reviews). NASA Langley Working Paper 412. Found insideAs of March 2006, 350 LRAD systems had been sold—to the US Navy, ...

The Long Range Acoustic Device [LRAD] (LRAD 2015), for instance, can be used to transmit ... 19 The device was intended for use as a communication device, however. Frequencies below 50Hz commonly lose their coherence and are perceived to pulse or fluctuate, which is analogous to the strobing beat of a modulated light.”. The PsyOps captain threw a switch and a voice reverberated from two loudspeakers attached to the machine- gun mounting. [31] As a result, this could lead to a plausible suggestion that military application of non-lethal audio weapons have not been made publicly available. Among the physical effects, we have a feeling of nausea, immobilization, inability to move, or to operate correctly, a general sense of sickness. In severe cases, these weapons can even cause serious damage like internal organ damage, and even death if someone is under its effect for longer. The LRAD, or Long Range Acoustic Device (pictured here on the right) can emit a blast of amplified sound capable of inducing headaches, panic, and potential hearing loss.

Found inside – Page 239... as they stepped off the private elevator, as if Leora's guests had been marshaled to replicate the debilitating effects of a long-range acoustic device. The pain causes people to flee an area, and can have lingering physical effects, including migraines and ringing in the ears, for up to a week. Infrasound: A Summary of Interesting Articles. It can also amplify voices or recordings to a level that is loud and clear but not painful or debilitating. Nonspecific responses of humans to infrasound (e.g., a temporary increase in heart rate) have been reported.108 In a study by Okamoto et al.,109 body sway was observed to be more prominent in humans exposed to infrasound of 15 Hz, compared with 10 Hz, but no changes in respiration, blood pressure, pulse rate, and several other measures were found. Report FMV:ELEKTRO-A12:142/83. It is the LRAD’s highly directional and high decibel sound that perhaps allows us to see the effect of the Brain Stem Reflex discussed in section 3.1. I’ll probably be returning to see more, thanks for the info! 9. Acoustics research has shown that the nonlethal weapon capabilities of audible sound generators have been grossly overstated. Known as a Long Range Acoustic Device, it’s the latest in a series of military grade “sonic weapons,” capable of emitting 150 dBs — enough to burst your ear drums — at a range of 984 feet. Much similar to that of the American ‘Long Range Acoustic Device’ discussed later within this section. Found inside – Page 332This new technology uses radiated energy to achieve the same effect as blunt ... Another directed energy device includes the Long Range Acoustic Device. From Long Range Acoustic Devices used to disperse protesters to ear-splitting military drones to songs blasted on rotation to prisoners, ours is an … . Some potential nonlethal weapons proposed for law enforcement agencies may be adapted from military technology. At sound pressure levels as low as 120 dB, resonances in the nasal cavities or sinuses appear to be related to a heightened sense of touch in that area of the body.76 Allen et al.77 reported a tickling sensation in persons in the vicinity of a 165-dB sound source. No physiological experiments were conducted, but it was estimated that at such a pressure it would take from 30 to 40 seconds to kill a man. The frequency was from 800 to 1500 impulses per second.

So, when the NYPD fired a Long Range Acoustic Device, or a LRAD, at the demonstration in 2014 in Manhattan, that's exactly what Edrei, 24, did. The use of infrasound in such small volumes would not appear to be relevant to hostage rescue scenarios. The LRAD, too, fulfills a similar function of allowing the free movement of certain goods and people, as evidenced by the large number of commercial tankers, luxury cruisers, and yachts that are now equipped with “pirate proof” LRADs in order to flow more easily through the Saudi Gulf. (Davies & Honours, no date) cites that “Many of the most profound effects of sound are attributed to infrasound in the region of 7Hz. A Long Range Acoustic Device system aboard the command ship USS Blue Ridge, 2013. Infrasonic weapons like the long range acoustic device rely on loud, low frequency sounds (infrasound). Ultrasound maintains very directional wave forms, due to their smaller wavelength and is very easily absorbed by materials, which allows for a greater application of use than other frequency bandwidths (Carovac, Smajlovic, & Junuzovic, 2011). |, https://www.youtube.com/watch?v=4d9H_1ygEv8, Anti-Pirate Water Cannon (Unifire) - Design and Violence, Design and Violence as Open Curatorial Experiment at the Science Gallery Dublin, Ireland, Design and Violence Debate IV: The Internet, Open Wide, Lethal Injection (Chapman, Wiseman, Dawson, Deutsch). As preciously mentioned, the central mechanism of the ear is the cochlear; within the cochlear there are two sensory cells, the inner hair cells (IHC) and the outer hair cells (OHC) (Cook, 1999). Moore et al.57 suggested that effects of exposure to acoustic energy could be expected to range from “disorientation to even lethality.” Noppen et al.58 speculated that exposure to music from commercial loud speakers (ranging down to 30 Hz) could have caused four cases of spontaneous pneumothorax. As described in, Secret Weapons of the Third Reich (E. Simon, 1971), one such device is discussed: “…design consisted of a parabolic reflector, 3.2 meters in diameter, having a short tube which was the combustion chamber or sound generator, extending to the rear from the vertex of the parabola. Long range acoustic device or LRAD is a term coined by the LRAD Corporation, which developed the technology after the attack on the USS Cole in 2000. The Long Range Acoustic Device (LRAD) is an acoustic hailing device developed by LRAD Corporation to send messages and warning tones over longer distances or at higher volume than normal loudspeakers.
