A unique sound alleviates motion sickness
- 14 1y agoHope 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.
- hengheng 1y agoAh, the calming sound of a power supply humming in the background.
- jpmattia 1y agoWho would have thought that a power supply hum could be so annoying as to make people forget to be carsick.

- jawns 1y agoThis 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
- akdor1154 1y agoYeah, nice. Easy enough to self-test, Android signal generator apps are readily available. I wonder if the optimal tone varies with body shape/size?
- diggan 1y agoKind 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.
- behringer 1y agoShould be real easy with a cheap sound meter off of Ali express.
- K0balt 1y agoUnless 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. Sad.
- zoklet-enjoyer 1y agoThere are free phone apps for that
- K0balt 1y agoYes, wildly inaccurate ones in most cases. The Apple Watch has a comparatively well calibrated sound pressure meter though. (Made in China, obviously)
- CoastalCoder 1y agoWhy bother with a psychoacoustic measure like dBA or dBZ for a pure sine wave?
- lamename 1y agoProbably 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.)
- DidYaWipe 1y agoWhere does it say it's a sine wave, though? I was looking for a description of the waveform, and found none.
- CoastalCoder 1y agoThe 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.
- DidYaWipe 1y agoThanks. I pretty much assumed sine wave too, but it's never stated. The idea that that's "unique" is laughable.
- AStonesThrow 1y agohttps://en.wikipedia.org/wiki/Brown_note https://en.wikipedia.org/wiki/Brown_note
- jraby3 1y agoTo 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."
- NetOpWibby 1y agoThat's disgusting
- AStonesThrow 1y agohttps://hellraiser.fandom.com/wiki/Coil 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. https://www.discogs.com/release/197912-Coil-The-Unreleased-Themes-For-Hellraiser https://www.discogs.com/release/197912-Coil-The-Unreleased-T... 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.]
- lambdaone 1y agoSo quite literally mains hum, at least in countries with 50 Hz systems, since the magnetostriction effect makes the second harmonic dominant.
- phkahler 1y agoSo piano music with a droning G chord for a minute.
- tgv 1y agoThat has a lot of overtones. If this is truly based on some weird psycho-acoustic effect, a piano tone might not work.
- bhaney 1y agoUnblinded, 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.
- janalsncm 1y agoWe don’t need a peer reviewed study to test it out. https://m.youtube.com/watch?v=Cdi0jQtMqV8&pp https://m.youtube.com/watch?v=Cdi0jQtMqV8&pp
- thesparks 1y agoAm I the only one who started to feel a bit nauseous listening to this? I'm serious.
- pomian 1y agoThat 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.
- BugsJustFindMe 1y agoUh...no... 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.

- mcherm 1y agoThis 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.
- temp0826 1y agoI 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.
- nandomrumber 1y agoIf 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.
- pbhjpbhj 1y agoWhen 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.
- jedimastert 1y agoFor 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.
- RossBencina 1y agoI'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).
- pbhjpbhj 1y agoWhat other frequencies did they try? Maybe there are better frequencies (or combinations) but they haven't tested for that yet??
- dataviz1000 1y agoDesign motor yacht engines to produce 100hz sound for an extra selling point.
- modeless 1y agoMy 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.
- zoklet-enjoyer 1y agoLow 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.
- bombela 1y agoSo 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.
- DidYaWipe 1y agoLOWERED 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.
- m3kw9 1y agoWho has the mp3 medicine?
- Geee 1y agoAfaik 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.

- tempestn 1y agoProbably 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...
- kazinator 1y agoA 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.
- hrtk 1y agoIf it’s a sound, it should come with a play button
- wenjian 1y agohere you go, the simple online tone play website I made: https://100hzsinetoneonline.1link.fun https://100hzsinetoneonline.1link.fun
- 8474_s 1y agoHow 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)
- teekert 1y agoStory 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. At the time this was pretty shocking to me.
- begueradj 1y agoIt'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.

- snailmailman 1y agoThe ability of pure placebo to actually work quite often is crazy to me.
- 486sx33 1y agoWow this is an amazing discovery that could help so many people. AirPod app?
- mikewarot 1y ago100 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

- wenjian 1y agoI 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~ Hope it helps you: https://100hzsinetoneonline.1link.fun https://100hzsinetoneonline.1link.fun
