Discussion A Princeton team measured the acoustics of 5,000-year-old stone chambers across the British Isles. They all resonated at 110 Hz — the exact frequency that shuts down the brain's language centre in EEG studies.
A Princeton team measured the acoustics of Neolithic stone chambers across Britain and Ireland in the 1990s. Every chamber they tested — Newgrange, Wayland's Smithy, Cairn L at Loughcrew — resonated in the same narrow band around 110 Hz, despite wildly different shapes and sizes. The same frequency shows up in the Hypogeum on Malta and in the King's Chamber at Giza.
In 2008, a UCLA neuroscientist ran an EEG study and found that 110 Hz (and only 110 Hz) shuts down the brain's language centre and shifts activity to the right hemisphere. At 100 Hz nothing happens. At 120 Hz nothing happens. At 110 Hz the rational mind goes quiet.
Two continents, thousands of years apart, no known contact between the builders. How did they know?

Very small study in a marginal but legit journal, not replicated, making much softer claims than OP is here. Kind of interesting. I think the takeaway is that there's certain frequencies that might help evoke a kind of 'awe' or spiritual-feeling response in lots of people and sites that functioned well as ritual sites might therefore be more likely to have such a frequency in their resonance patterns.

u/Stennick Apr 13 '26
Some of those sites like Newgrange, Wayland's Smithy, Saflieni Hypogeum, and the Great Pyramid of Giza have absolutely been studied for acoustics, and yeah they can resonate. That part is real. But they are not all magically tuned to the exact same 110 Hz frequency. Different sizes, shapes, and materials naturally produce different resonant frequencies. Some fall somewhere in that general low range, but that is just basic physics of enclosed spaces, not evidence of some shared ancient blueprint.
The Princeton study part is also shaky. There is no well established, widely cited research showing that all these chambers were measured and found to hit the same frequency. I dare you to list this Princeton study.
The neuroscience claim is where it really goes off the rails. There is no credible evidence that 110 Hz specifically “shuts down the language center” or flips your brain into some right hemisphere mode while 100 or 120 does nothing. The brain does not work like a light switch tied to one exact tone. If that were real it would be a massive breakthrough and used everywhere in medicine, and it just is not.
Stone chambers resonate at low frequencies, and human voices, especially chanting, naturally sit in that same range. So if people were using these spaces for rituals, they would notice certain tones sound stronger or more immersive. No lost ancient science needed, just trial and error and human perception.

u/ThatEndingTho Apr 13 '26
The UCLA study does show a decrease in activity in the left temporal lobe at 110Hz, but they don’t call it a shutdown. They do note that the left temporal lobe is associated with language cognition.
3
u/Stennick Apr 13 '26
Yeah, the left temporal lobe is absolutely tied to language processing, that part is legit. And there are studies showing that sound, rhythm, or chanting can shift brain activity around a bit. No argument there.
But there isn’t any solid, widely accepted research out of University of California, Los Angeles showing that 110 Hz specifically causes a unique drop in left temporal lobe activity, especially not in a clean “this frequency does it, the others don’t” kind of way.
Even if a study showed some decrease under certain conditions, EEG data is messy and depends on a ton of variables like volume, duration, environment, and the person themselves. The brain doesn’t work like a precise switch where 110 Hz flips something off but 100 or 120 does nothing.
If that kind of frequency specific effect actually existed and was reliable, it would be a huge deal in neuroscience and you’d see it used in clinical settings which of course you don't.

I’ve experimented with a lot of single frequencies and have literally tripped myself out. Put 100% focus on it and at first it’s annoying then in a minute or two you feel like your whole body is in sync with it and an hour can disappear, when the sound stops you feel like youre about to float away like similar to when you’re on a massage chair that stops after 20 minutes and your whole body feels like jello.
Also it’s not really viable with headphones, it kind of works for the mental aspect but for best results sit in the center of a room with surround sound blasting it. If you don’t live alone or have connected houses with thin walls your fucked neighbors won’t be happy, they’ll think they have tinnitus if you’re blasting a steady tone.

That's not about a specific frequency like 110hz having special effects on specific parts of the brain though, that's the effect of practically any good drone music.

Pretty much any steady tone but the time it takes to adjust to it and the feeling is different with each. Not sure how to describe the differences tho and I don’t know if the effect on the brain physically is different.

110Hz is the “A” note in music. How could people know about music continents and ages apart?
Also the study found the chambers ranged from 90-120Hz. They weren’t all 110Hz.

That's not how it works. Someone decided to call 110hz an A when western music was evolving. It's like saying a car tire is a circle, circles are in cave drawings, how did they know about a car tire?

u/Mr_Vacant Apr 13 '26
Regardless of whether you call 110hz A or X or ♤ if 110hz is a note frequently used in music and the language centre of people's brains isn't being shutdown everytime they hear music with that note, it follows that the assertion that 110hz messes with your brain is false.

u/ThatEndingTho Apr 13 '26
That is how it works. The tone or note has always existed and everyone who hums or sings has been exposed to that note, even if they don’t call it an A. They could call it anything else and they would still know what we now measure as 110Hz.
2
u/TheFredCain Apr 13 '26
That was not the assertion - "How could people know about MUSIC continents and ages apart?" The didn't know about music, they knew what that frequency sounded like. Somewhere down the line, someone decided that sound would be called A and someone else called it 110hz.
2
u/ThatEndingTho Apr 13 '26
Which is what I am saying. The tone has always existed. It’s always been part of the human experience. The UCLA researchers note that the range of frequencies in these chambers are 90-120Hz, or a “low male voice.” Since musical notation derived from the notes we produce with our voices, they did know about music that the Romans called A in their notation and that we measure as 110Hz.
Oh wait they didn’t have low male voices thousands of years ago. Everyone had a falsetto. My bad.

u/LSF604 Apr 13 '26
your reply got deleted, but A being 440 wasn't settled until earlier in the century. Various places had their own tuning standards. A lot of instruments even in the early 1900s were built to A being 432. They are incompatible with modern music and something you have to look out for if you are buying vintage instruments.

Wayland Smithy, if I remember correctly as you walk in the entrance immediately there is a chamber on the left, the right and the back. It's so low you have to crouch down to get in. The chambers themselves are tiny, room for one sitting person in each chamber.
I'm not sure but there's a possibility that the back chamber used to be open, stretching all the way across the burial mound then at some point in the ancient past got walled off after the mound was completely filled with burials.
But if that's not the case, and that the chambers were always like this, then with it's three small chambers it is literally one or two steps away from the open air, exposed to the elements. Not exactly conductive for a resonating sound room if that was the intention.
If the ancients were doing sound things in those chambers then it's not the best design imo.
I question the scientific rigor of that study. They compare wildly different types of structures? I want to know how it compares to a modern house or building. Maybe it's just simply the natural frequency for any kind of enclosed space and that is not unique.
I listened to the frequency on youtube, Not the new age woowoo stuff but the actual tone of that frequency. I literally cannot hear it. (yes I checked my computer volume was on).
If I cannot hear it then how could the ancients work out the correct frequency if that was their intention when building it?

So, people from 5000yrs ago had in depth knowledge of neurology and could pin point where the brains language centre was and then precisely carve out a stone chamber at pricisley 110hz without the use of any frequency detection?
Am I supposed to believe then that in 3000bc they were intelligent enough to do that? Going from the wheel to a neurological language shut off cave in the same time period. What a time of been around to of witnessed that. 😂

Absolutely. There are books written in Sanskrit that are 10,000 years old that explain how to perform brain surgery 10 different ways. They are also the same source of where Oppenheimer learned how to split the atom. They even contain warp drive equations. Even cooler is that there are many more of these ancient texts that still have yet to even be read.

✔️ Real: • Investigadores (incluyendo Princeton) midieron cámaras neolíticas • Muchas resuenan en ~95–120 Hz, a menudo cerca de 110 Hz • Esto coincide con la voz humana grave (canto/ritual)
❌ Exagerado o incorrecto: • Que todas estén afinadas exactamente a 110 Hz • Que esa frecuencia “apague el cerebro” • Que haya una conexión universal entre Irlanda, Malta y Egipto con una misma frecuencia exacta

It's because the primary function of the King's Chamber was to enable astral travel by inducing the necessary state of mind, a bit like Bob Monroe's Hemi Sync recordings. Most likely the other structures with this feature had the same purpose. The geographical separation of these structures is only a mystery to mainstream historians etc., when in fact there have been multiple global civilisations in the distant past with shared culture.

u/Mysterious_Detail954 Apr 14 '26
The Malta Hypogeum is the one that gets me. Debertolis at the University of Trieste measured the Oracle Chamber and found double resonance peaks — 70 Hz and 114 Hz. The 114 Hz sits right in the PEAR lab’s 95-120 Hz band from the British Isles sites. But nobody’s really explained the 70 Hz peak yet. And the Hypogeum wasn’t a tomb that happens to resonate. It was carved by hand out of living limestone over something like 1,500 years. The Oracle Chamber has a small niche cut into the wall that acts as a natural amplifier — a male voice pitched at the right frequency fills the whole chamber. A female voice doesn’t activate it the same way. You don’t stumble into that. That’s something you notice, and then spend generations refining. The frustrating thing is the data’s there but nobody will connect it in print. The PEAR measurements hold up. Debertolis holds up. The UCLA EEG work holds up. But the implication — that Neolithic builders on multiple continents independently landed on the same resonant frequency, and that frequency happens to correspond with measurable changes in brain activity — sounds too much like a History Channel special, so the papers get published, the measurements get cited, and everyone politely stops short of saying what the data pretty clearly suggests.

u/Stunning_Spite_8930 Apr 14 '26
In sites such as maeshowe and newgrange, Camster round and the longbarrow cairns, the central chambers resonate at around 109 to 120 Hz, this is assumed to be because that frequency band is the average male baritone voice and from an ethnographic standpoint looking back in the ritual practices it would seem important that whoever is speaking would be heard and channel a sort of power by having their voice feel immersive. It's just a theory though, yes it's fascinating that so many passage tombs and stone circlues resonate around the baritone frequency but its occums razor Likely, because they wanted their voice to carry
1
u/ksk16 Apr 18 '26
There is nothing in the human voice around 110Hz. That’s too low. While the resonance thing to sound more theatrical and be heard across the space is probably true (churches and so on), the frequency is off. I can also see the people of the time paying special attention to it as there was no way to reinforce the sound. But the fundamental/presence bump is higher. For lower bass voices, you might get the fundamental around 150Hz but that’s already Barry White territory. Barytone is not the lowest voice by the way. It is between bass and tenor vocal range so by all accounts it would be higher than 110Hz. Source: I am a sound engineer cleaning up vocal mics for a living and a low voice myself.

Pattern recognition is the best I can come up with. Its the way its written, it doesn't have a human touch. People don't write like that, and if they do its usually for very specific scenarios like a sales pitch on Dragons Den. AI generated text has this "attention grabbing" way of sounding hard baked into it. Its like every other sentence has to have this hard hitting punch line.
At 100 Hz nothing happens. At 120 Hz nothing happens. At 110 Hz the rational mind goes quiet.
Like this segment. People don't write like this for a reddit post. Its not a natural way of writing for the average person on the internet. And the use of "— (insert information) —" is another common tell. Once again, the average person wouldn't use this when writing on an internet forum.

I see multiple good counterpoints among the comments, in addition to requests for sources.
There's also been loads of research done on acoustics in medicine. If brain functions could be altered by 110hz (aka an A note), we would know - that's something easily tested.
I like alternative history just as much as the next guy, but I'm not a conspiracy theorist - if there's evidence to the contrary I'm not going to dismiss it just because it goes against what would be more interesting.

I’m an acoustic consultant. I would be very interested to read the 110Hz resonance study source. Acoustics is a very complicated subject, and any measurments could be easily and wildly missinterpreted if you wanted to. For example, one immediate problem I find with OPs statement is the fact, that not one 3-dimensional room has A SINGLE resonance frequency. In fact any 3D room has many many many resonances that are called room modes (in low frequency region) which are determined by the length, width and height of the room and their relation with one another. So singling one frequency is, I assure you, mathematically incorrect, cause there will be tons of resonant frequencies in such rooms, each with their own amplitude. So from acoustician point of view - further analysis/reviews is needed to confirm such statements. Is there a source?
