Description

TECHNICAL FIELD

[0002] Infrasound wave refers to the sound wave with a frequency less than 20 Hz (Hertz). Infrasound wave is not easy to attenuate and is not easy to be absorbed by water and air. The wavelength of infrasound wave is often very long, so it can diffract around certain large obstacles. In nature, sea storm, volcanic eruption, large meteorite landing, tsunami, thunder and lightning, wave hitting shore, water vortex, air turbulence, tornado, magnetic storm, aurora, earthquake and the like can be accompanied by the occurrence of infrasound wave. In human activities, such as nuclear explosion, missile flight, artillery firing, ship sailing, car racing, high-rise building and bridge shaking, even like air blower, mixer, loudspeaker and the like can also produce infrasound wave while making sound.

[0003] The inherent vibration frequency of human internal organs is very similar to the frequency of infrasound wave (0.01 Hz-20 Hz). When the frequency of external infrasound wave is the same as or close to the frequency of internal organs, the resonance state of human internal organs is formed, various adverse reactions are caused, symptoms such as blurred vision, difficulty in swallowing, liver function disorder, severe limb numbness, chest compression and the like are caused, and the internal organ system of human body is vibrated and damaged to death when the inherent vibration frequency of the abdominal cavity, thoracic cavity and cranial cavity of human body is consistent with the frequency of external infrasound wave.
