Neither the microphones, nor the speakers in NC headphones will work a those frequencies.
So the claim is essentially impossible.

Your link address cannot be opened due to the blocking of China's network firewall. According to the Chinese website, this kind of Active Noise Cancellation can offset low-frequency noise, but not high-frequency noise. Carsickness is caused by low-frequency noise, so this kind of Active Noise Cancellation can avoid carsickness.

It is wrong.
How could the noise cancelling work at low frequencies where the microphone and speaker do not work?

You need to stop believing everything you read, and think a bit.

Carsickness is caused by low-frequency noise

No.
Because some deaf people get carsick.

The link you provided also proves that this Active Noise Cancellatio nearphone can counteract low-frequency noise, so wearing this Active Noise Cancellation earphone can avoid carsick: Generally speaking, this type of active noise cancellation is most effective on lower frequencies of sound, between 50 Hz and 1 kHz. (If you’re curious about what 1 kHz sounds like, watch this video.) This is partly because lower frequencies produce longer waveforms that are easier to line up properly. Also, at higher frequencies, if the waveforms don’t line up just right, you’re more likely to encounter feedback. So most active noise-cancelling headphones have a noticeable dip in usefulness right at the 1 kHz point. This is why ANC is better suited for reducing low, sustained sounds like those of motors and airplane engines, and it’s why such headphones can’t filter out screaming kids.

Some ANC headphones will produce low-frequency noise and cause motion sickness. For example, ANC headphones create a noticeable hum below 20 Hz that makes you feel uncomfortable or sick (constant low-frequency sound waves are known to cause nausea, stress, and extreme discomfort). Nevertheless, the three ANC headsets I’ve mentioned perform fantastically, with zero or imperceptible noise, delivering the best user experience possible and keep you safe from motion sickness.

And here's what the article says
"Naturally, since the brain is not used to the absence of ambient noise, it reacts in such a way that you feel sick, dizzy, claustrophobic, nauseous, have motion sickness, or the impression that the air pressure is abnormally high. In short, you feel different from your natural environment, which is understandable."
Apparently it's understandable- but not to you.
There's no mention of infrasound- because it's irrelevant.

Have you ever been in an anechoic chamber? You get the same sensation.

I am beginning to think this could be a disguised spam attempt-to promote a particular "cure for motion sickness". What other explanation could there be for such dogged unwillingness to accept sound scientific argument together with error repetition ad infinitum?

Now, all scientific papers believe that carsickness is caused by low-frequency noise, not by motion. We should believe the opinions of scientific papers, not those published in textbooks and encyclopedias that violate scientific papers. In addition, after I pointed out the error of motion sickness entry to the editorial department of Encyclopedia Britannica, the editorial department of Encyclopedia Britannica has replied me to correct the error in the next publication.

No, they do not.
It still can't be caused by sound (of any frequency) because some deaf people get it.
Also, the driver and passengers are exposed to practically identical infrasound (They are well within 1 wavelength of each other) but have very different incidences of motion sickness.

Your idea makes no sense.

Only experiments with low-frequency noise can replicate the symptoms of carsickness. All other experiments with motion sickness can only simulate the symptoms of carsickness, and cannot replicate the symptoms of carsickness. All scientific experiments have fully proved that low-frequency noise is the only cause of carsickness.Human beings should reflect on why a pseudoscientific theory that violates the conclusions of scientific papers can be accepted by all people.

Did you know that nausea actually gets its name from sea sickness?

So, even the ancient Romans knew you are wrong.

No, because deaf people get carsick.
And the driver , exposed to the same infrasound, is much less susceptible than the passengers.

People get motion sickness on merry-go-rounds where there's very little infrasound.

All the day-to-day evidence still shows that you are wrong.
So does the science.

Many people in this article also believe that carsickness is caused by low-frequency noise

The best you can do is a page that says

"Some researchers suggest that low frequency sounds may also play a part in causing motion sickness. They argue that the sound, as well as the vibrations, of vehicle engines and the swell of the sea may disorientate our bodies and trigger nausea. It seems to be a controversial theory, however, as other experts discount it completely."

The page also points out what is probably the best example of proof that you are wrong.
"Conversely, motion sickness can also be triggered by the eyes seeing movements, but the body feeling nothing (for example with simulators, 3D movies and IMAX shows)."

None of those would produce infrasound.

You really are very clearly wrong.

Just a word of advice, saying something that is clearly not true tends to destroy your credibility, not that you currently have any in this thread.

There are over 3 different types of motion sickness.Therefore, the cause of motion sickness does not mean that it is the cause of carsickness or seasickness, just as the cause of hepatitis does not mean that it is the cause of hepatitis A or hepatitis B.

The opinions of experts and textbooks are not credible. Only the conclusions of scientific papers are credible. You can't find a scientific paper that carsickness is caused by motion.

Who do you think the experts are?

Did you not realise they are the same people?

But, just for a laugh... show us the scientific papers that support your view.
