I'm just curious about what papers he has misunderstood/ misrepresented/ whatever.

The opinions of experts and textbooks are not credible. Only the conclusions of scientific papers are credible.
Who do you think the experts are?
Who do you think writes the scientific papiers?

Did you not realise they are the same people?

But, just for a laugh... show us the scientific papers that support your view.
This article introduces that many scientific papers have proved that carsickness is caused by low-frequency noise. https://stopthesethings.com/2013/09/28/sick-again-motion-sickness-sufferers-cop-it-worst-from-giant-fans/      On the contrary, you can't find a scientific paper that carsickness is caused by motion.

In short, we should believe the conclusions of scientific papers and not easily believe the opinions of some experts in textbooks and encyclopedias. No scientist dares to lie publicly in a scientific paper, because if other scientists cannot replicate the same results in the experiment, the scientist will be immediately disgraced. However, many experts dare to lie openly in textbooks and encyclopedias. Because the readers of these books are ordinary people, who are unable to test these opinions by experiments. The most typical is the lie of motion sickness experts about motion sickness in the British encyclopedia.

OK, here's a quote from that paper.
"  A relationship between frequency, G force and vomiting was established in this study"

In addition to the low-frequency noise experiment, which can replicate the symptoms of carsickness, the experiments of other factors can only simulate motion sickness, which cannot replicate the symptoms of carsickness. Therefore, it is not the cause of carsickness.https://en.m.wikipedia.org/wiki/Simulator_sickness

This problem is not important. What is important is that the opinions of experts on motion sickness in textbooks or encyclopedias violate the conclusions of all scientific papers.

Make up your mind.
Either it's important, or it isn't.

That makes no logical sense.  The experts on motion sickness write the scientific papers!?!  So you are saying the experts disagree with themselves. :o

Here is some anecdotal data.  I was on submarines in the Navy and when we were submerged deep enough there was no detectable movement of the sub and no one got sea sick.  When we would go to periscope depth in rough seas many people would get sea sick from the motion of the sub.

Because the methods of avoiding carsickness introduced by experts are all deceptive and completely ineffective. As a result, many people (mainly women) with good low-frequency hearing all over the world dare not travel or go to work by car all their lives. If everyone knows the method of active noise reduction headphones to avoid carsickness, then these people can immediately travel or go to work by car like ordinary people.

The article you quoted explains where noise cancelling headphones make people feel sick, not counteract carsickness. You are talking utter nonsense as ever. The only thing you appear to have proved is that you are a complete fool.

This is another of these threads without hope of any degree of progress. Simply repeating the same nonsense again and again does not validate it. The op is beyond the reaches of logical argument, possibly deliberately so.

For example, even without staying on the airplane, the noise of airplane engine can also cause symptoms of carsickness.

See my earlier comment about people throwing up in a glider. No engine noise, no vibration, much unexpected and disorientating motion, upchuck every time.

Sailing boat likewise: lunch overboard mostly when running downwind in relative silence, never a problem tacking or on a solid beam reach with a roaring gale: the difference is "sloppy" motion when running, especially goosewinged.

I've never had anyone throw up in a hot air balloon - massive rumbling noise, no disorientating motion.

Overwing seat of an A 320 - not much to see, but very little movement, no vomit. Rear seat - this aircraft fishtails on autopilot, same noise, lots of unpredictable movement, good chance to review your breakfast.

But why let umpteen years of slightly mad experience interfere with an unproven hypothesis?

PS every time I try to pronounce the OP's nom de plume, it sounds exactly like a victim of mal d'air in a scrappy thermal. Fortunately the microphones on our noise-cancelling heasets have replaceable covers.

I explained before that there are two reasons why this will never work.
Even if you refuse to recognise that low frequency sound isn't the cause of carsickness, you still need to explain how the 'phones could work given that they don't cancel low frequency sound.

Indeed. I'm running out of metaphors and synonyms for vomiting. Once one of our chums from downunder contributes "chunder" or any other selection from the rich Antipodean vocabulary of reverse alimentary evacuation, I think we can consider the matter exhausted.

Parting comment on airsickness, however. Cabin crews report previously happy customers vomiting when the engines stop and the aircraft plunges silently earthward. QED, I think.

We welcome new theories and ideas, especially those backed by well conducted research. However, the deliberate misquotation of articles and scientific papers is not acceptable.
For this reason, this thread has been locked. Any attempt to reopen a similar topic will result in a ban.
