Women only seem to be more susceptible to motion sickness than men because they have better hearing.Dog more prone to motion sickness than people because dog have better hearing than people.

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.

I can tell how I think it it works in my case. I have sea sickness that occurs after about half an hour, and also if i am onboard  a  helicopter for more than 3-4 hours.
In the past I have experienced a period of chronic fatigue that made me even more sensitive to motion. I have onserve that if I played on a computer a game that I wasn't used to the motiom mechanics, I would get that sickness quite quickly. A 3d video for example can make almost anyone feel sick. Therefore, the sickness must be related to the brain. If the motion you experience doesn't match what the brains expect to happen the brain needs to learn the new mechanics. If the flow information that comes is high, I suppose that some hormones are activated that enables the brain to cope with the high demand. However, if the hormone production cannot keep upwith  the requirements the hormones levels go down and the brain cannot handle the situation well and you get sick. Now that I have passed the chronical fatigue phase, I can cope much better with things like that. The chronical fatigue was confirmed by symptoms like poor sleep during night and sleepiness during the day, slow recovery after exercise, poor digestion, joint pain, poor immunity (frequent colds),etc.
As a conclusion, it should be related to the hormone production capacity and overal endocrine strengthness.
Also if you have a problem with the inner ear for example it can cause random inputs that confuse the brain.

Your  question  has  already  been  thought  about  a  lot,  if  seasickness  is  caused  by  shaking,  then  why  until  now  there  is  no  exercise  specialist  says  that  the  cause  of  motion  sickness  have  been  found  in  the  world  is  shaking?  But  why  do  the  real  recognized  reasons  of  motion  sickness  not  be  found?  I  always  take  the  boat  with  a  big  quake,  but  I  never  have  the  feeling  of  seasickness  and  never  see  the  people  around  me  have  the  slightest  seasick  symptom.The  old  crew  on  the  sea  almost  all  the  year  round  has  said  that  the  more  shaking  the  boat  is,  the  less  possibility  to  get  seasick.  Thus  it  can  be  seen  that  seasickness  has  nothing  to  do  with  shaking  and  sports.  Ancient  Chinese  and  ancient  Greece  had  a  view  that  the  boat  sailing  on  the  sea  would  cause  nausea  when  it  met  sandstorms(Because  carsickness  and  seasickness  only  have  the  signs  of  nausea  and  vomiting  with  no  vertigo  syndromes.  Only  rotation  will  have  symptoms  of  dizziness  and  seasickness.  Carsickness  and  seasickness  with  the  symptom  of  dizziness  are  fabricated  by  experts  to  confuse  the  symptom  of  carsickness  and  seasickness  with  that  of  dizzy.)  There  is  no  saying  that  ancient  people  would  feel  nausea  when  they  took  the  shaking  carriages  with  large  turbulence,  this  is  because  the  shaking  of  ancient  carriage  is  very  violent,  but  there  is  no  engine  producing  low-frequency  noise,  that  won't  cause  carsickness.  Different  reasons  will  inevitably  lead  to  different  results.  If  the  shaking  of  boat  can  really  cause  seasickness,  so  this  kind  of  seasick  symptom  caused  by  shaking  and  seasickness  caused  by  low-frequency  noise  will  certainly  be  different,  which  can  just  prove  seasickness  has  two  reasons,  low-frequency  noise  and  shaking  that  will  cause  relevant  two  different  seasickness.  As  I  discovered  in  1992,  the  nightmare  was  caused  by  two  palpitations,  racing  heart  and  slow  beating,  which  would  correspondingly  cause  being  pursued,  attacked  and  people  flying  up  and  down.  So  seasickness  has  the  same  story  with  these  two  common  nightmares.

Different causes will generate different results. Motion sickness is caused by in-situ rotating motion, 3D visual movement, and low-frequency noise three main causes, with completely different symptoms. The corresponding in-situ rotating motions may cause symptoms of dizziness, 3D visual movement may cause mild dizziness, and low-frequency noise may cause nausea, vomiting, and drowsiness. That is to say rumbling low frequency noise may cause carsickness, seasickness, and airsickness.

when my younger brother started growing some angry-looking pits and zits on his face, I understood that I should help. I found a blog where tells about basic skincare and acne treatment.  Suffice to say, he was able to clear the blemishes and acne within weeks of using it.

Scientific theories can also be testable and make falsifiable predictions.For instance, a view holds, Carsickness is caused by special low-frequency rumbling noises. Hence people with acute hearing become sick easily, while deaf people who can’t hear any noise do not get carsickness. Also, even when people are standing near an airplane rather than riding on the car, the stimuli from the low-frequency rumbling of the airplane’s motor still triggers intense airsickness.We not get carsickness can't hear the low dull rumbling sounds from the aircraft, trains, subways, trucks, motorcycles, tractors.People get carsickness on trains or subways running at the same speed when hearing low-frequency noise. If any evidence can be cited to prove that deaf people also get carsickness yet can avoid it by not riding any vehicles, this opinion can be invalidated. In reality, however, pseudoscience cannot be falsifiable predictions. For instance, a pseudoscience opinion that carsickness is caused by 3D optokinetic stimulation cannot be overturned by the fact that the blind still gets carsicknes

It has been proved that deaf people don’t get motion sickness.for example

John Zakutney, one of 11 deaf NASA volunteers whose deafness made them immune to motion sickness, being lowered into a centrifuge tank to study the effects of space flight, ca. 1964

No, it has not.
https://www.britishsignlanguage.com/bsl-dictionary/sea-sick/

Some deaf people get seasick; others don't.

But your idea is stupider than that.
Do you think the people go deaf when they stop reading and look out of the window?
Because, for many people, that's enough to stop motion sickness.

Scientific theories can be confirmed. introducing several causes of a disease, a scientific researcher will further explain different consequences resulting from each cause to prove his opinion.For example, nightmares are caused by the symptoms of tachycardia. bradycardia or premature beat.and the most awful temporal brain ischemia cardiovascular diseases, which are also common in healthy people during the day. Correspondingly, dream of being chased or dream of attacked;dream of flying in the air or dream of falling down and the most awful sleep paralysis these three kinds of nightmares with different clinical manifestations will be caused.Motion sickness is caused by axis rotation,3D visually induced and low-frequency noise three main causes, with completely different symptoms. The corresponding axis rotation may cause symptoms of the most awful dizziness, 3D visually induced may cause mild dizziness, and low-frequency noise may cause nausea, vomiting, and drowsiness. That is to say rumbling low frequency noise may cause carsickness, seasickness, and airsickness.
On the contrary, pseudoscience is confined to introducing the causes of nightmares and motion sickness, without further explaining each causes different clinical manifestations. Otherwise, the lie will be self-defeating.

Not really; you can't prove that a scientific theory is true; but you can sometimes show when one is false.
That's what happened with your idea.
It's wrong.
Get used to it.

It's true thatgyrating movements、 a 3d video can make almost anyone feel sicka, but the symptoms caused respectively by gyrating 、a 3d video and carsickness are quite different. Gyrating movements 、a 3d video will cause dizziness, while carsickness usually causes nausea or sleepiness. This is why authors of many scholar articles only state that gyrating 、a 3d video symptoms are associated to carsickness, but the reasons behind carsickness are still unknown. Only unreliable knowledge popularizing articles say that the reason of carsickness is gyrating movements、a 3d video. This is not true. Actually, gyrating movements a 3d video are not related to carsickness, which is actually caused by a special low-frequency noise. Only this kind of noise can cause exactly the same symptoms of carsickness. For example, even without staying on the airplane, the noise of airplane engine can also cause symptoms of carsickness. Experts of carsickness around the world all know that only noise can cause exactly the same symptoms of carsickness, but they fraud people by saying that this phenomenon is only a psychological reaction!

Here is a similar story: Harvard and the Brigham call for more than 30 retractions of cardiac stem cell research

Anversa Opened a Wong Door, Thomas Closed a Right Door

When I read The Emperor’s New Clothes as a kid, I did not take it seriously. Funny though, I did not think it would ever happen for that was just the adults’ wild imagination to fool the kids around. After growing up, I realized this can truly happen in the adults’ world. Jaw droppingly, smart and decent people are usually involved

The symptoms caused respectively by gyrating and carsickness are quite different. Gyrating movements will cause dizziness, while carsickness usually causes nausea or sleepiness.

For example, even without staying on the airplane, the noise of airplane engine can also cause symptoms of carsickness. Fifty years ago, more or less, Republic Aviation built a turboprop jet fighter based on the F84. It was designed to be transonic and the design propellor tip speed was supersonic. During ground tests of full power and prop RPM it was discovered that every member of the ground crew was rendered violently nauseous by the resulting high frequency ( beyond normal hearing range ) noise.Experts of carsickness around the world all know that only noise can cause exactly the same symptoms of carsickness, but they fraud people by saying that this phenomenon is only a psychological reaction!

There are over 3 different types of motion sickness , each with their own causes, symptoms, and treatments.For example:
This type of terrestrial motion sickness is particularly prevalent when susceptible people are watching films presented on very large screens such as IMAX, but may also occur in regular format theaters or even when watching TV or playing games. For the sake of novelty, IMAX and other panoramic type theaters often show dramatic motions such as flying over a landscape or riding a roller coaster. This type of motion sickness can be prevented by closing one's eyes during such scenes.However, this method is not effective for motion sickness caused by spinning motion and low frequency noise.
