Stonehenge 3D Model Proves Incredible Acoustics | Ancient Architects

A team from the University of Salford have collaborated with experts from English Heritage to create a scale model of Stonehenge in order to fully understand the acoustic properties of the ancient monument.
To construct the model at 1/12th scale, the stones were made using 3D printer technology to ensure accuracy as well as specialised moulding techniques. Silicon moulds were then made and these moulds were used to cast the stones, which were made out of plaster that was mixed with a polymer. They were then spray painted grey to match the colour of the real stones.
The model stone circle is 7.5 feet or 2.3 metres wide and is the best, most accurate reconstruction of Stonehenge ever made, thanks to the use of laser scan data, but it was the acoustic properties of a completed Stonehenge that the experts were most interested to explore.
The experiment was a success and the team now believe they have a greater understanding of the acoustic environment of Stonehenge when it was apparently completed around 2,200 BC. It acted like an enclosed room, as opposed to an outside space, reinforcing, speech, singing and chanting. Watch the video now to learn more.

[@chuffpup]

I would hope the results have been, or will be, made available. I suppose a bit of Googling might locate something. But, yes I agree. I guess it's a bit like those plate echo chambers, or natural reverberation. I can see the musicians are going to be interested in trying the Stonehenge effect. 😎

It said in the video that the frequency had to be increased by a factor of twelve, making it impossible for us to hear, and I'm sure decompressing it would distort the results.

It's my understanding that the stones themselves have acoustic and electro-magnetic properties. Recreating them from concrete and polymer will only give a partial picture

Electromagnetic indeed. Why would they pull the stones all the way from South Wales? The gneiss infused rock interacts with the human electro magnetic field. Just like wifi does...

or at least recreate using the same stone in miniature and on an energy line convergence like the real one...

[@chalichaligha3234]

@@ThrottleAddiction , It is always good to consider potential experimental errors, however I can safely say that this is not one of them. That is because the fraction of sound that reflects from a material's surface instead of passing through it is equal to the ratio of the densities between the substance the wave is in before it reaches the material, and the material itself. In other words, both rock and plaster are near ideal mirrors for sound, because they are orders of magnitude denser than air. There is only a point considering harmonics is the sound actually enters the material itself, thus it doesn't matter for the experiment which you use.

[@chalichaligha3234]

@@ThrottleAddiction ,That's fair enough. Stonehenge doesn't seem to be terribly sophisticated from an acoustic viewpoint anyway. They said "amazing properties" but that seems to just be sensationalist as they don't quantify what that means beyond the existence of reverberation. It is obvious that if you arrange a lot of tall mirrors in a circle you are going to get a lot of reflections.

[@surfk9836]

Stones have very little electro magnetic properties. That's why grounding is used as an insolator. Acoustic properties arise from the source, the stones would reflect the properties. That said, it is interesting and not at all illogical to consider that acoustics played a roll in the design.

[@mons.romerodurante8086]

The work of David Cowan shows the acoustic properties of megalithic installations in regards to their alignment with leylines. The mainstream narrative asserts that stone age cultures built these circles as an expression of _art_ as they now had huge amounts of free time since giving up the hunter gatherer lifestyle. The soil in the areas with megalithic circles is naturally of a poor quality, invariably dense with stony layers. So it seems that instead of 'having something to do with the transition' these megalithic circles _are_ the transition. I suspect there are many groups which have retained the knowledge as to leveraging teluric energy for soil fertilisation purposes. However, it's not really in the interests of Monsanto Bayer for this knowledge to be in the popular consciousness.

[@harri7416]

Thanks. Great insight. Personally for me there is an interaction between the gneiss infused stone, teluric currents and the human electro magnetic field too. Maybe a place to heal?

[@mons.romerodurante8086]

@@harri7416 I would go further and say that the introduction of the henges and barrows facilitated a more finely tuned symbiotic relationship between the people and the land. In a comparable way, the wind blowing against a chime activates the sound which makes a zen garden grow in a balanced and healthy way. The oxygen and carbon dioxide created by the healthy plants then contributes to the local weather system and the cycle continues. I say 'people' , but I don't think they were the same as contemporary humans. I suspect they were more akin to the homo paracas touted by Brien Foerester. If so, they had quite a different cranial architecture with fewer sutures and greater capacity. Thereby allowing them to naturally perceive and harness subtle energies in ways that still elude our fossil fuel paradigm.

[@chalichaligha3234]

@@mons.romerodurante8086 , It's good not to take everything they tell us at face value, however it is also true that whatever extra sensory ability these humans may have had, our modern scientific instruments are far more sensitive. Our tools can detect things that no animal can. And thus far we have no evidence that animals can sense things that we can't with our instruments. An example is birds navigating around the world, we wondered how they could do that, there was evidence that they could sense something we can't because crucially they could do something we can't. But now we now the sense the Earth's magnetic field, but we can do it far better now. Don't get me wrong, I think it's great to think outside the box and imagine the possibilities, but you need to provide evidence every step of the way, like the scientific community has. What evidence is there for subtle energy? if there is any, I'd genuinely be interested as I'm an engineer, so I want to guide and channel all the forces of nature for the betterment of the human condition in harmony with the environment, which is unfortunately not what we have seen under fossil fuelled capitalism

[@mons.romerodurante8086]

@@chalichaligha3234 You have missed the critical point, we require these super advanced tools to perceive teluric energy - the architects of henges did not.

If you don't believe in dowsing, you should probably discount wells, mineral seams and aquifers as also being fiction.

From what I have seen, control trials show no improvement by using dowsing over random chance. I may be wrong, but please find me a strong lead, evidence, anything. I want to know about telluric energy, like I know about electromagnetism, or at least have some unsolved leads that point to it's existence. Can you convince me?

With all the new information/understand coming out - slowly - about, the acoustic values of various stones/monutments; all around the the world, it makes complete sense that this would have inevitably been incorporated into the design and function of the monument. The "singing rocks, spread around the the world from Europe, Indian,African & other disperate places,seem to indicate that this property was once very well understood. Stones with different "notes" being transported sometimes thousands of miles to then fulfil a purpose - the function ,was part of a grater,understanding of which, the truth ,is now effectively lost?! It doesn't make it any less fascinating. Thanks as always for a great video. Wishing you & yours and awesome week👋🌟✌

I think ancient people fully understood acoustics and the effects, just look at some of the places round the world, just look at the Moray Ruins in The Sacred Valley Peru. I think it's the reason for the giant rooms of Petra. They are all over the world. I think they used sound vibration, for healing maybe but I'm sure they understood something we have forgotten.

Sam Hill commissioned the Henge in 1918 in Honor of the Veterans of WW1. Now it is a Memorial for all Veterans of Foreign Wars. If you also like wine it is a good place to visit. Sam Hill created a place for a agriculture based community. It has Orchards and Vineyards between the Museum and Stonehenge Memorial with a tasting room and shops. All in a 5300 acre parcel he originally purchased in 1914.
