It sounds like a pitch that you might hear from an airplane propeller, which leads to the question why airsickness exists if the antidote is ambiently present?
It would be completely bonkers for an antiemetic to commonly induce an emetic urge in any but rare exceptional cases.
Most seasickness drugs are just first-generation antihistamines sometimes combined with a caffeine analogue to counteract the sleepiness.
Dramamine/Gravol (dimenhydrinate) is just benadryl (diphenhydramine) plus the caffeine analogue theophylline.
Bonine/DramamineII (meclizine) is also a first-generation antihistamine.
Promethazine is also a first-generation antihistamine.
Non-antihistamine antiemetics like ondansetron or scopolamine transdermal patches require a prescription from a doctor and therefore aren't commonly used for motion sickness except for occupational seafarers. And it would still be absolutely stupid if the drugs given to prevent nausea commonly caused nausea.
I think it’s not uncommon for a drug treating some condition with some symptom to have a potential side effect that worsens that symptom. When you start playing with some set of receptors, it’s possible something goes too far or, for whatever reason, not far enough and now we’re worse off
See: antidepressants can increase suicidal ideation, cannabis (used for nausea) can cause nausea at higher doses, etc.
> I think it’s not uncommon for a drug treating some condition with some symptom to have a potential side effect that worsens that symptom.
I think you're making the error of conflating probabilities here. It's not uncommon for drugs to have uncommon side effects, but those side effects are still uncommon. Every once in a while benadryl makes a person paradoxically excited, but most people who take benadryl get sleepy.
As an occasional user, can confirm that motion sickness pills (e.g. Cinnarizine, one of the most used in the British Navy) make dizzy, some more than other, and that it’s still much better overall than not taking them.
Why would it be stupid? You are concentrating on the vomiting part but aren't other sensations related to motion sickness like shaky balance that drugs could help out with?
Not to mention the possibility of triggering a response that the trigger would help combat if you already exhibited the response. Or it simply being an uncommon side effect that it's made worse. Headaches and nausea are listed in possible side effects for just about everything, because if anyone reports it they have to list it since the possibility of causality hasn't been ruled out.
It's a sine (or sine-like) sound at a low pitch (around G2). Our ears aren't great at those frequencies, and the speaker you use might be bad at that range too. It's a bass frequency, but most bass sounds have a lot of overtones, which makes them sound clearer than the fundamental.
Double blind randomized controlled trial or it didn't happen. The subjects have to fill a form. It's common that people want to be nice and lie a little. Also, the exitement of the experiment may make them less focused in the problem, or there may be many other additional effects that are dificult to control. A DBRCT minimize them.
Anyway, if the researchers are not blinded there are many possible sources of errors.
Perhaps they do the first test in the morning, the sound just before lunch and the second test in the afternoon is made by another person that is more/less friendly to the rats, or the rats has the stomach more full/empty.
After changing a program and running benchmark, I sometimes run it again if the new program is not faster as I expected. I even gave a second chance to deterministic test, that is as useful as it sounds. It's possible that if the rat does not collaborate the researchers hit's the equivalent of Ctr-F5 just to be sure.
It's hard to be 100% neutral, so a method is to not know to ensure all rats have exactly the same test conditions.
Under capitalism, what do you want? If you went and put in a bunch of your own time, money, and effort into something, is asking for something back so you can put food on the table so reprehensible? I mean, I'd love it if I were independently wealthy and could go off and do a mission like that and just give it away for free, but some of us didn't get a trust fund and have bills to pay and so, is that really so ridiculous?
Using the heavy hand of the state to threaten violence against people who make a particular tone... yes that is really so ridiculous.
The tone is question is quite close to G2. So, if your guitar is slightly sharp, you'll be making this tone when playing one of the most common chords.
Nobody is threatening violence against you for playing your guitar sharp. I have no idea where violence even came into play here.
It’s a registered trademark. A registered trademark is a legal designation that provides exclusive rights to a brand name, logo, or other distinctive symbol used to identify a specific product or service; they registered Spice Sound or whatever as a trademark.
They did not patent 100Hz.
You would only be liable if you walked around playing your sharp guitar with a sign that said “Get your Spice Sound here” heh
I’m not defending it, and it reminds me of that woman in Baltimore who pissed everyone off by trademarking “Hon”, causing the whole city to
revolt against her.
But it’s far from “threatening violence,” and they’re not patenting the sound.

And what happens to you if you don’t abide by the legal protections of the trademark? The government must ultimately use violence or the threat of violence to enforce its rules.
That’s not how audio trademarks work. A sound trademark can represent a product (think Intel jiggle, MGM lion roar) but it can’t be the product.
So in this case I suppose they might be able to Trademark ’Antivomotone’ as a word mark to describe the tone, but no-one is going to be able to trademark the tone itself.
If I discovered that oxygen cured diabetes I couldn't just patent oxygen. This is a discovery (if it ever holds up) that a sound makes you feel a certain way, the authors didn't invent anything

Story time: My parents bought an anti motion sickness thing. It was a rubber band with metal core hanging from the car’s chassis to the ground.
It worked for my brother! But at some point I asked my parents: but how can this work then!? What does it do with “motion “?
My parents told me to be silent and later, when my brother couldn’t hear, told me it was just to release static electricity but they told my brother it was against motion sickness and him believing that made it work for him.
It's the same when it comes to medication: if you believe it will help you, there is a big chance you will heal even quicker. Trusting the doctor who prescribed the medication also plays a role in healing.
This is a university press release, so they first refer to a registered trademark, which I assume means they're trying to make money off it through licensing agreements:
> a unique sound called 'sound spice®'
Only at the very bottom of the release do they actually give any technical details:
> a pure tone at 100 Hz
The linked study gives more details:
> 1-min exposure to a pure tone of 80–85 dBZ (= 60.9–65.9 dBA) at 100 Hz
Probably because dB SPL doesn't match A-weighted human perceptual audiogram, so they're being specific? (I get that you could just translate it to dB SPL but still.)
Kind of feel like it'll be hard to replicate the volume accurately, even when assuming headphones. The maximum output would depend both on the phone itself and the headphones. Wonder how specific it would have to be, if you'll get the same results with different volumes.
Well, I was thinking more it's really hard for any layperson so reach a specific level of dBA, especially for single-frequency tones where the perceived loudness is usually different from the actual loudness.
So even if you say "This 100 Hz tone should be played for 2 minutes at 61 dBA, which is regular human speech levels", being able to actually get close to 61 dBA for a 100 Hz tone in real life, for an untrained ear, sounds pretty difficult.
Unless you live in the USA, in which case that sound meter now costs X+$100 if it gets here before June, x+$200 if it gets here in june or later lol.
But that’s fine, you can get an American made one for about ….hmm. Can’t seem to find one actually made in the USA that doesn’t say “contact us for a quote” or something like that.
I’m all for repatriating manufacturing, and a good plan might very well involve tariffs rolled in progressively over several years, giving businesses a predictable time table to shift supply chains and invest in manufacturing capacity to fill those gaps.
But all that has happened is the price of American innovation just went through the roof for small companies and startups, while big businesses will barely be affected because the cost of gadgets and parts is negligible as a fraction of their R&D budget. For many startups it’s nearly 100 percent.
Chaos is not good for business and multiplies risks at their root, which gets magnified by orders of magnitude in financial terms when looking at investment and finance.
100:1 bets with 1000:1 odds just becomes 100:1 bets with 100:1 odds, a bet no longer worth taking.
This seems quite promising: an effective treatment for a problem that frequently assails many people, and a treatment which is so simple and easy to apply.
In fact, it seems so promising, that it raises my hackles of suspicion. I would very much like to see other researchers replicate this. I am automatically more skeptical than I would be of most research because if humming a certain note were an effective treatment for motion sickness, then it would be rather surprising that people had not already discovered this property -- possibly just by listening to various pieces of music.
Just as research which suggests a surprising outcome or one inconsistent with existing theories must meet a higher bar, so too does research which suggests a simple cure that it was already possible for people to stumble across.
I was on a ROUGH ferry ride between some islands in Southeast Asia once. It was packed and nearly everyone succumbed to puking. Even if it's minimally effective, I feel like playing this over the speakers in the common areas would have been welcomed.
If a specific tone can decrease the incidence of nausea and vomiting I wouldn't be surprised if rough seas combined with typical diesel engine sounds (frequency / harmonics - whatever the correct terminology is) increases the incidence of nausea and vomiting.
When I've felt nauseous on boats it has _felt_ like the thrum (ie deep pitched vibration with sound) of the engines has contributed to that. Also, when you can smell the engines it doesn't seem to help.
Afaik this isn't a new idea. This has been studied previously in the context of VR motion sickness.[0] There is a company called Otolith Labs making these kind of devices.[1] They seem to have pivoted from VR to curing chronic vertigo.
And they really are nauseating. I put aftermarket springs on my car that were only supposed to lower it an inch, and instead got 2.5" of nauseating, pavement-slamming sag. Removed those with a quickness.
For those not wanting to click through a bunch of links, here is a quote of the results of the study. TL;DR a sine wave of 100Hz at conversation level.
> Results: The effect of short-term (≤5 min) exposure to a pure tone of 80–85 dBZ (= 60.9–65.9 dBA) at 100 Hz on motion sickness was investigated in mice and humans. A mouse study showed a long-lasting (≥120 min) alleviative effect on shaking-mediated exacerbated beam test scores by 5-min exposure to a pure tone of 85 dBZ at 100 Hz, which was ex vivo determined as a sound activating vestibular function, before shaking. Human studies further showed that 1-min exposure to a pure tone of 80–85 dBZ (= 60.9–65.9 dBA) at 100 Hz before shaking improved the increased envelope areas in posturography caused by the shakings of a swing, a driving simulator and a vehicle. Driving simulator-mediated activation of sympathetic nerves assessed by the heart rate variable (HRV) and vehicle-mediated increased scores of the MSAQ were improved by pure tone exposure before the shaking.
I'm curious about how to explain 100 Hz working for both mice and humans. I would not have expected the same frequency for animals of such different sizes (and different vocal frequency ranges).
My friend has pretty extreme motion sickness that prevents us from taking boats or buses or even sometimes taxis when traveling together. It's kind of debilitating and not that uncommon I think. More effort ought to be put into finding a cure. (I'm skeptical of this one, but worth a shot I guess.) Would be nice for VR as well.
Hope this works and VR games start playing it before motion intense parts of the games. I have built up a tolerance for the most part but some games just leave me motion sick if I am not careful.
How its exactly 100hz?
Nature doesn't follow arbitrary measures, its likely the approximations of some nearby frequency in range that has maximal effect(likely something resonating in inner ear mechanisms)
Probably entirely placebo, but I just spun in my office chair until dizzy then pulled up a 100Hz tone, and as soon as it started playing the dizziness dropped noticeably. Again, I would guess placebo, but hey, if it works. Gotta try it on reading in the car...
"The brown note (sometimes brown tone or frequency) is a hypothetical infrasonic frequency capable of causing fecal incontinence by creating acoustic resonance in the human bowel. Considered an urban myth, the name is a metonym for the common color of human faeces. Attempts to demonstrate the existence of a "brown note" using sound waves transmitted through the air have failed.
Frequencies supposedly involved are between 5 and 9 Hz, which are below the lower frequency limit of human hearing. High-power sound waves below 20 Hz are felt in the body."
During the production of the first Hellraiser film, [the band Coil] were asked by director Clive Barker to compose the film's score. Their music was described by Barker as "bowel churning." The group completed nine tracks for the score, however the music was rejected by the producers, who wanted a more traditional, classical-based movie score.
Coil is the only group I’ve heard on disc whose records I’ve taken off because they made my bowels churn. -- Clive Barker
[Note: AStonesThrow met Clive Barker at San Diego Comic Con in the mid-1990s, and presented this very disc for his autograph, and he obligingly signed it with the Sharpie provided. Very nice guy in person. Yes: Coil's music is disgusting, reprehensible, vile, and usually unlistenable. Stay well away.]
A couple of years ago I discovered being able to make a headache go away by humming low notes, at frequencies that make my head resonate and teeth chatter.
Unblinded, tiny sample size (n=10), and a ridiculous attempt to trademark a pure 100Hz tone.
I'm gonna wait for a much better study reproducing this before I put any stock in it, personally.
I first found it hilarious that there are 9 authors for a 10 person experiment, but I double checked.
There are multiple experiments with 82 total participants. One of those experiments does indeed have a sample size of 10.
Yup, this is still “wait and see”. For these kinds of papers my stance is: “cool read, I won’t click the share button”.
We don’t need a peer reviewed study to test it out.

CTRL+SHIFT+I and in the console
If you click anywhere it will start/stop.It sounds like a pitch that you might hear from an airplane propeller, which leads to the question why airsickness exists if the antidote is ambiently present?
Am I the only one who started to feel a bit nauseous listening to this? I'm serious.
it made me feel slightly uneasy. Brains are weird
That may be a good thing. Most of the seasickness drugs make you queasy, if you don't go out on a rolling sea after taking them.
Uh...no...
It would be completely bonkers for an antiemetic to commonly induce an emetic urge in any but rare exceptional cases.

Does that mean when death is listed that somebody died during the trial?
> You are concentrating on the vomiting part
The nausea part. The person I'm replying to specifically said "queasy".
Should I have been able to hear something? I feel like my ears need popped now
It's a sine (or sine-like) sound at a low pitch (around G2). Our ears aren't great at those frequencies, and the speaker you use might be bad at that range too. It's a bass frequency, but most bass sounds have a lot of overtones, which makes them sound clearer than the fundamental.

Is using a 100Hz tone to alleviate motion sickness not patent worthy? Does not seem obvious.

> 1-min exposure to a pure tone of 80–85 dBZ (= 60.9–65.9 dBA) at 100 Hz
Why bother with a psychoacoustic measure like dBA or dBZ for a pure sine wave?
Probably because dB SPL doesn't match A-weighted human perceptual audiogram, so they're being specific? (I get that you could just translate it to dB SPL but still.)
Where does it say it's a sine wave, though? I was looking for a description of the waveform, and found none.
The article refers to a pure tone at 100 Hz.
I took that to mean a simple sine wave. If it wasn't a sine wave, it would have additional, non-100 Hz components.
Thanks. I pretty much assumed sine wave too, but it's never stated.
The idea that that's "unique" is laughable.
Yeah, nice. Easy enough to self-test, Android signal generator apps are readily available. I wonder if the optimal tone varies with body shape/size?
Kind of feel like it'll be hard to replicate the volume accurately, even when assuming headphones. The maximum output would depend both on the phone itself and the headphones. Wonder how specific it would have to be, if you'll get the same results with different volumes.
If this works at all I seriously doubt it only works within a .2 dB range or something.
Just because a study tested only one particular point in a space does not mean only that point has whatever properties they found in the study.
Well, I was thinking more it's really hard for any layperson so reach a specific level of dBA, especially for single-frequency tones where the perceived loudness is usually different from the actual loudness.
So even if you say "This 100 Hz tone should be played for 2 minutes at 61 dBA, which is regular human speech levels", being able to actually get close to 61 dBA for a 100 Hz tone in real life, for an untrained ear, sounds pretty difficult.
> 60.9–65.9 dBA
That's about the level of normal human speech.
Should be real easy with a cheap sound meter off of Ali express.
Unless you live in the USA, in which case that sound meter now costs X+$100 if it gets here before June, x+$200 if it gets here in june or later lol.

There are free phone apps for that
Yes, wildly inaccurate ones in most cases. The Apple Watch has a comparatively well calibrated sound pressure meter though. (Made in China, obviously)
You can get a fine spl meter on Amazon or get my favorite which is the old Radio Shack one with a needle meter on eBay. Probably about $20-25.
Many people could probably hum a 100hz tone.
How would I know if I did it right ?
Your motion sickness would feel better
Just have perfect pitch! That should be no problem, right? .....right??
This seems quite promising: an effective treatment for a problem that frequently assails many people, and a treatment which is so simple and easy to apply.

So quite literally mains hum, at least in countries with 50 Hz systems, since the magnetostriction effect makes the second harmonic dominant.

Ah, the calming sound of a power supply humming in the background.
Who would have thought that a power supply hum could be so annoying as to make people forget to be carsick.
So that's the reason for all those old honda civics cars full of speakers with windows shaking bass!
They are just trying to alleviate motion sickness from those old suspensions.
LOWERED suspensions.
And they really are nauseating. I put aftermarket springs on my car that were only supposed to lower it an inch, and instead got 2.5" of nauseating, pavement-slamming sag. Removed those with a quickness.
I have made a website that play the 100hz sine tone, also have a timer, so that you can give a try.
A few users has already reported to me that it works~

For those not wanting to click through a bunch of links, here is a quote of the results of the study. TL;DR a sine wave of 100Hz at conversation level.
> Results: The effect of short-term (≤5 min) exposure to a pure tone of 80–85 dBZ (= 60.9–65.9 dBA) at 100 Hz on motion sickness was investigated in mice and humans. A mouse study showed a long-lasting (≥120 min) alleviative effect on shaking-mediated exacerbated beam test scores by 5-min exposure to a pure tone of 85 dBZ at 100 Hz, which was ex vivo determined as a sound activating vestibular function, before shaking. Human studies further showed that 1-min exposure to a pure tone of 80–85 dBZ (= 60.9–65.9 dBA) at 100 Hz before shaking improved the increased envelope areas in posturography caused by the shakings of a swing, a driving simulator and a vehicle. Driving simulator-mediated activation of sympathetic nerves assessed by the heart rate variable (HRV) and vehicle-mediated increased scores of the MSAQ were improved by pure tone exposure before the shaking.
I'm curious about how to explain 100 Hz working for both mice and humans. I would not have expected the same frequency for animals of such different sizes (and different vocal frequency ranges).
What other frequencies did they try? Maybe there are better frequencies (or combinations) but they haven't tested for that yet??
My friend has pretty extreme motion sickness that prevents us from taking boats or buses or even sometimes taxis when traveling together. It's kind of debilitating and not that uncommon I think. More effort ought to be put into finding a cure. (I'm skeptical of this one, but worth a shot I guess.) Would be nice for VR as well.
Low dose THC edible might help your friend.
For mild motion sickness from VR, I like to chew ginger root. Ginger candies are good too, especially if you don't like straight ginger root.
Hope this works and VR games start playing it before motion intense parts of the games. I have built up a tolerance for the most part but some games just leave me motion sick if I am not careful.
Any discussion of aural experimentation would be incomplete without KaTe Bush [and a cast to rival Harry Potter films] performing "Experiment IV"

"They told us all they wanted was a sound that could kill someone from a distance..."
How its exactly 100hz? Nature doesn't follow arbitrary measures, its likely the approximations of some nearby frequency in range that has maximal effect(likely something resonating in inner ear mechanisms)
Design motor yacht engines to produce 100hz sound for an extra selling point.
Who has the mp3 medicine?
Probably entirely placebo, but I just spun in my office chair until dizzy then pulled up a 100Hz tone, and as soon as it started playing the dizziness dropped noticeably. Again, I would guess placebo, but hey, if it works. Gotta try it on reading in the car...
Self-experimentation! Excellent.
So I'm not alone falling sick trying to read in a moving car after all?
So common it was even in the article:
“Even a single minute of stimulation reduced the staggering and discomfort felt by people that read in a moving vehicle”
"Am I the only one that <extremely common thing>?"
https://en.wikipedia.org/wiki/Brown_note
To save a click:
"The brown note (sometimes brown tone or frequency) is a hypothetical infrasonic frequency capable of causing fecal incontinence by creating acoustic resonance in the human bowel. Considered an urban myth, the name is a metonym for the common color of human faeces. Attempts to demonstrate the existence of a "brown note" using sound waves transmitted through the air have failed. Frequencies supposedly involved are between 5 and 9 Hz, which are below the lower frequency limit of human hearing. High-power sound waves below 20 Hz are felt in the body."
That's disgusting
https://hellraiser.fandom.com/wiki/Coil
During the production of the first Hellraiser film, [the band Coil] were asked by director Clive Barker to compose the film's score. Their music was described by Barker as "bowel churning." The group completed nine tracks for the score, however the music was rejected by the producers, who wanted a more traditional, classical-based movie score.

Coil is the only group I’ve heard on disc whose records I’ve taken off because they made my bowels churn. -- Clive Barker
[Note: AStonesThrow met Clive Barker at San Diego Comic Con in the mid-1990s, and presented this very disc for his autograph, and he obligingly signed it with the Sharpie provided. Very nice guy in person. Yes: Coil's music is disgusting, reprehensible, vile, and usually unlistenable. Stay well away.]
So piano music with a droning G chord for a minute.
That has a lot of overtones. If this is truly based on some weird psycho-acoustic effect, a piano tone might not work.
Wow this is an amazing discovery that could help so many people. AirPod app?
A couple of years ago I discovered being able to make a headache go away by humming low notes, at frequencies that make my head resonate and teeth chatter.
If it’s a sound, it should come with a play button
here you go, the simple online tone play website I made: https://100hzsinetoneonline.1link.fun
100 Hertz might work fine in Japan and Europe, but I bet 120 Hertz is the magic note here in the US. 8)
Doing this airborne would of course require an 800, 1200 or even 2400 Hhz tone depending on if the power supply was 2, 3 or 6 phase.
/S - yes, it's a joke about DC power supply ripple
