  • RE: What causes motion sickness?

    Roaring low-frequency noise instead of infrasound causes carsickness. Symptoms of carsickness get stronger when vehicles bump or shake more frequently, which is just a coincidence. It is just because low-frequency noise gets louder when bumping and shaking gets more serious. Without such low-frequency noise, people will not feel carsick no matter how hard the car bumps or shakes. For example, people get carsick on trains or subways running at the same speed when hearing low-frequency noise. Without such noise on trains or subways, carsickness can be avoided. It fully proves that low-frequency noise is the only reason that causes carsickness.
    By far, there has been no effective methods or progress to solve carsickness, as a result of false and deceptive carsickness theories brought up by authorities and experts. If people can acknowledge the view that low-frequency noise leads to carsickness, then they can immediately and completely get rid of carsickness, plane-sickness, or seasickness (part of seasickness is caused by low-frequency noise from storm at sea, which is unavoidable natural disaster) caused by low-frequency noise from the engine as long as all transportation tools stop generating such noises. It is readily feasible in terms of technology. Thus, if consumers purchase cars with loud noise, which is severe quality issue, they should immediately claim compensation from car manufacturers and require them to recall for remodeling until it stops making such nois...
