I believe that everyone or friends around you have experienced motion sickness, seasickness or airsickness, and authoritative experts in the medical field have done a lot of research on this, but there has been no obvious progress. Academician Ma of Institute of Acoustics, Chinese Academy of Sciences, while studying the influence of infrasound on people, accidentally discovered the real cause of carsickness-infrasound. This discovery took more than 90 years to be scientifically confirmed, but why hasn't it been made public? Maybe someone will suspect that what I said is pseudoscience, and the truth can't be concealed! Academicians, experts and professors of the Academy of Sciences are not stupid. Isn't this simple truth understandable by ordinary people? Nothing can be seen from the surface value, please remember! Taxpayers all over the world spend a lot of money to hope that medical experts can find the real cause of motion sickness and seasickness, but on the one hand, the research progress is slow, on the other hand, medical experts have made new "scientific research achievements" in response to the great spirit of innovation, and collectively call motion sickness, seasickness and airsickness motion sickness (you can learn more about it). A complete industrial chain has been formed in this medical field, from raw material suppliers, drug manufacturers and drug sellers to go-vern ment, a large number of medical experts and professors have formed a huge interest group. Therefore, various businesses have developed a huge market and earned huge profits. Go-vern ment has collected a lot of taxes, and related pharmaceutical products have also provided many jobs for the whole society, which has promoted economic development and social stability. Medical experts and professors also get a lot of R&D funds from it, and constantly make new "scientific research achievements". So this scam has not been exposed so far, and insiders don't say that laymen don't understand it. In this materialistic society, who will smash their jobs? Infrasound has been put forward for a long time, but the medical profession has been fooling the public and refusing to make it public! Infrasound refers to sound with a frequency lower than 20Hz. The full range of sound that the human ear can hear is 20 Hz ~ 20Hz~20000Hz, and different human domains have different values. The frequency range of infrasound is roughly110000 Hz ~ 20 Hz, so people's ears can't hear infrasound, but animals are not necessarily. Although infrasound can't be heard by human ears, its destructive power is amazing. Infrasound waves generated by high-altitude atmospheric turbulence can break the mast of a 10,000-ton ship and tear the plane into pieces; Infrasound waves excited by earthquakes or nuclear explosions can destroy tall buildings; The infrasound waves brought by the tsunami can destroy the houses on the shore. The natural frequencies of human organs and parts are between 0.0 1 ~ 20 Hz, which is similar to infrasound frequency. When infrasound waves act on human body, human organs are prone to vibration, causing dysfunction or injury, high blood pressure and general discomfort; The balance function of the brain will also be destroyed, so people will have a sense of rotation and nausea (many people living in high-rise buildings will feel dizzy and sick when there is a storm, which is why infrasound waves are at work). If the vibration frequency of infrasound is lower than 10 Hz, it can cause human tissues to vibrate. Mild people, dizziness, vomiting, difficulty breathing, even coma, paralysis, and even visceral rupture and death. Therefore, motion sickness, seasickness and airsickness are all caused by infrasound noise generated by the engine of the vehicle and boat. We can control the noise to a certain extent, so as to reduce the bad situation caused by infrasound. 1, reducing infrasound noise. Generally speaking, the infrasound noise of aircraft is the biggest, followed by high-speed subway, followed by ships and ordinary buses. Motorcycles, tractors and trains are very quiet, so no matter how they move or bump, few people get carsick. We can't change the infrasound of the vehicle, but we can choose the vehicle. 2. Reduce infrasound noise in the transmission path. The more closed the place, the louder the noise will become, which is a common sense problem of acoustic experts. Therefore, air-conditioned cars are more prone to carsickness than ordinary cars, and the infrasound noise of motorcycles and tractors is much less. Everyone knows that sitting by an open window is much more comfortable, and some infrasound waves will spread through the air. At the same time, some sound absorption, sound insulation and vibration isolation equipment can be used to reduce infrasound noise, but this condition is generally not available. 3. Protect recipients and organs. Ordinary people can reduce the impact of infrasound noise on themselves through headphones and earmuffs, but this can not completely eliminate the impact of infrasound noise on the body. The wavelength of infrasound noise is more than ten meters. If an object wants to stop infrasound from propagating forward, its diameter must be 10 meters or more. However, if the ear is completely blocked with objects or fingers, the sound pressure introduced into the inner ear can be greatly reduced.

If there is any deviation, please don't chew the text. There are no two identical leaves in the world. For more complex human beings, even the same person can't be in the same state twice. Different people have different body structures. Some people get carsick, and some people don't, even if they don't have exactly the same symptoms. To give a few examples, deaf people don't get carsick and seasick; Women's hearing is better than men's, and they are more prone to motion sickness and seasickness; After the age of 50, people's hearing will drop significantly, and the incidence of motion sickness will also drop significantly. So these methods may have a weak or insignificant effect on some people, but I still hope to provide some inspiration and help to everyone. Infrasound noise is the main cause of motion sickness and seasickness. Taking medicine for carsickness and seasickness can improve the symptoms of nausea and vomiting to some extent, but it can't really solve the problem of carsickness and seasickness, and there is no medicine in the world that can really make people not get carsick and seasick. For example, someone keeps hitting a certain part of your body, which is very sensitive. Do you believe that taking some medicine will not hurt? If you say you can inject anesthetic, forget it. Next time you can knock yourself out with a car, you won't have to spend money on carsickness. Therefore, many ordinary people find ways to block their ears with headphones or earplugs to prevent motion sickness and seasickness, which is a really effective way to solve motion sickness and seasickness. Secondly, psychological effects also have some influence. Different moods, different physical conditions, but if we use the method of diverting attention to solve the problem of motion sickness and seasickness, it is also a temporary solution.
