What kind of infrasound is harmful? What are the dangers of infrasound?

Infrasound waves are both very energetic and may resonate at the same frequency as some organs of the human body.

As long as infrasound waves are harmful, they may cause resonance in the body's organs.

Infrasound waves should all be harmful, 4 Hz 8 Hz infrasound waves are harmful to the human body.

Did you know that the human body also has vibrational frequencies?

The natural frequency of the organs of the human body is 3 17 Hz, the natural frequency of the head is 8 12 Hz, and the natural frequency of the abdominal organs is 4 6 Hz.

Infrasound is a kind of sound wave that vibrates very little per second and cannot be heard by the human ear The frequency of infrasound is very low, generally below 20 megahertz, but the wavelength is very long, and the propagation distance is also very far It is farther than ordinary sound waves, light waves and radio waves For example, infrasound waves with a frequency of less than 1 herd can be transmitted to places thousands to tens of thousands of kilometers away In 1960, Chile, South America, had a large **, ** infrasound waves generated when it spread to every corner of the world! In 1961, the Soviet Union carried out a nuclear explosion in the Arctic Circle, and the infrasound waves produced actually circled the earth five times before disappearing!

Infrasound waves have extremely penetrating power, not only penetrating the atmosphere, sea water, soil, but also through solid reinforced concrete buildings, even tanks, submarines and airplanes When infrasound penetrates the human body, it can not only cause dizziness, irritability, tinnitus, nausea, palpitations, blurred vision, difficulty swallowing, stomach pain, liver dysfunction, numbness of limbs, but also may damage the cerebral nervous system, causing major damage to brain tissue Infrasound waves have the most serious impact on the heart, Eventually, it can lead to death

For the application of ultrasound, we are more familiar with the commonly used B ultrasound in hospitals, which is to inject ultrasound into the human body, according to the changes in the conduction and reflection ability of human tissues to ultrasound to judge whether there is abnormality, such as lesion examination of human organs, stone examination, etc., it has the advantages of no damage to the human body, simple and fast

Sound waves with a frequency of less than 20 Hz (Hertz) are called infrasound. Infrasound waves are not easily attenuated and are not easily absorbed by water and air. Infrasound waves, on the other hand, tend to have a very long wavelength, so they can diffract around some large obstacles.

Some infrasound waves can circle the Earth for 2 to 3 cycles. Due to the similarity of the vibration frequency of certain frequencies with human organs, infrasound waves are easy to resonate with human organs, which is very harmful to the human body and can cause death when dangerous.

People have a certain frequency range for the perception of sound, about 20 times per second to 20,000 times of vibration, that is, the frequency range is 20Hz-20000Hz, if the object vibration frequency is lower than 20Hz or higher than 20000Hz, the human ear can not hear, the frequency higher than 20000Hz is called ultrasound, and the frequency below 20Hz is called infrasound. Therefore, not all the vibrations of objects make sounds that we can hear. In addition, in order to be able to hear the sound, there must also be a medium through which the sound is transmitted.

The frequency of the sound wave less than 20 hertz is called infrasound, the wavelength of the infrasonic wave is very long, and it is not easy to attenuate, not easy to be absorbed by water and air, can make people dizzy, nausea, vomiting, loss of balance and even mental depression, therefore, infrasound waves are very harmful to the human body.

Infrasound waves are characterized by wide reach, long propagation, and the ability to travel far around obstacles. Infrasound has a very low frequency of sound waves, below 20 Hz, but the wavelength is very long and travels a long distance. It travels farther than normal sound, light, and radio waves.

For example, infrasound waves with frequencies below 1 Hz can travel thousands to tens of thousands of kilometers away. Infrasound waves are extremely penetrating, not only through the atmosphere, seawater, and soil, but also through buildings made of solid reinforced concrete.

Infrasound waves travel at the same speed as audible sound waves due to the low frequency of infrasound waves. The atmosphere absorbs very little of it, and when the infrasound wave travels thousands of kilometers, its absorption is less than a few ten-thousandths, so it travels far away, and can travel thousands of meters to hundreds of thousands of kilometers away.

Infrasound waves can harm human health and interfere with the normal function of the human nervous system. Infrasound waves of a certain intensity can cause dizziness, nausea, vomiting, and loss of balance. Stronger infrasound waves can also cause deafness, coma, insanity, and even death.

Analysis: Infrasound, also known as subsound, is a sound wave with a frequency lower than the frequency range of audible sound waves of a person. The frequency range of infrasound waves is roughly 10-4 20 Hz.

Infrasound waves have very low frequencies but long wavelengths and can travel great distances through the air. .Not only wind, thunder and ** in nature can emit infrasound waves, but infrasound waves may also be artificially created.

Because the frequency of infrasound is very low, the absorption coefficient of the atmosphere to infrasound waves is very small, so its penetrating power is extremely strong, and it can propagate to extremely far away and the energy attenuation is very small, and the 7Hz infrasound wave can not be blocked by a thick wall, and the infrasound wave can penetrate more than ten meters thick steel plate and concrete. .The action of turbulence causes attenuation of infrasound waves, but their effects are so small that they are usually omitted.

Infrasound has been shown to cause people to become anxious, extremely sad and cold, a study that validates the long-held belief that there is a link between infrasound and strange sensations. The tiger's roar before predation can produce an infrasound wave of 18 hertz, which can cause the prey to panic or even coma. .

The mystery of the Bermuda Triangle accident may be that the infrasound waves generated by the wave oscillations act on the crew, causing them to become insane or even die, and thus lose their ability to aircraft or ships...Ocean infrasound waves generally occur under storms and strong winds, and their frequencies are below 2o hertz. Take the crest part of the wave surface ...

When a sea vessel encounters this kind of infrasound waves of strong energy, infrasound waves can cause radiation to living organisms, which can cause fatigue, pain, and even blindness.

Infrasound is a high-power device that can emit low-frequency sound waves below 20 Hz, that is, infrasound. .At present, the infrasound wave ** is divided into two types: neurological type and internal organ type, the former can make people nervous disorder and madness; The latter can cause severe discomfort around the person, and then lose...

The advantage of infrasound** is that it is raidable. Infrasound waves travel at a speed of more than three hundred meters per second in the air and even faster in the water...It can reach about 1500m.
