Infrasound weapons can only kill living things, but they can't destroy objects without hearing, such as buildings and artifacts. Their power can kill people several kilometers away. First, infrasound waves in nature

Infrasound waves (the frequency is less than 2 Hz) are lower than the hearing limit of human beings. Biologists have observed animals using infrasound waves for communication for centuries. When peacocks show their feathers, male peacocks will emit infrasound waves that people can't hear, and other male peacocks can also hear such sounds. When the female peacock hears the sound, she becomes alert, and the male peacock is likely to give a harsh warning.

Infrasound waves have a long wavelength, so they can be diffracted around some large obstacles. Because the vibration frequency of some frequencies is similar to or even the same as that of human organs, infrasound waves are easy to generate * * * vibration with human organs, which is very harmful to human body and can cause death when it is dangerous. ? Second, infrasound weapons

infrasound will affect the normal function of the nervous system and cause harm to human health. A certain amount of infrasound can make people dizzy, nausea, vomiting, loss of balance and even depression.

Some people think that carsickness and seasickness are caused by infrasound waves when cars and ships are driving. Residents who live more than ten stories high often feel dizzy and nauseous when encountering strong wind, which may also be due to the infrasound generated by the swaying of high-rise buildings. Strong infrasound waves can also lead to deafness, coma, mental disorder and even death. ? Third, infrasound weapon experiment

In p>194, the Germans threw phonograph records signed by famous musicians at the British. These records were specially recorded, and infrasound was added. This kind of records could cause the audience to feel flustered, fearful and other mental disorders, thus causing riots. In addition, according to foreign media reports, in 1986, when the infrasound experiment was conducted by the French Ministry of Defence, infrasound suddenly rushed out of the laboratory, causing a family of 1 people who were eating 16 kilometers away to lose their lives.
