I have played my violin in several Greek amphitheatres and modern performance venues really can't compare. I enjoyed Epidarus, but my absolute favourite amphitheatre is at Ephesus. I don't really have words for the experience of playing there. What I can say is that I spent over 5 hours playing. Someday I hope to do a live recording there. It's such a remarkable space.

@Mary Ann the Nytowl I trained classically, but these days I am predominantly a fiddler. I play most Canadian styles, though I tend to favour Cape Breton fiddling.

When I went to Ephesus, I didn't play anything in particular, I just improvised. It was remarkable. If you want to listen to an amazing album, check out Oliver Schroer's Camino. It's a collection of improvised music he recorded in various small chapels and churches along the Camino de Santiago. You can hear the shape of the space he's playing in. Absolutely incredible.

There is something about those kinds of spaces that pick up the music and lift it into something truly special.

We tend to forget that just because ancient peoples were not as technologically advanced as we are now, they were still just as smart. Trial and error are powerful tools.

I think we underestimate our ancestors. When you look at the engineering that went into Newgrange for example - they built that 5000 years ago and it still works like "clockwork".

AKumar528

Not necessarily trial and error. They had very advanced knowledge but it was in books. Imagine some Alexander or Mao or Genghis or bakhtiyar khilji destroyed data centers today

AJ

Werner Herzog made an amazing documentary called Cave of Dreams. It's about a cave that had recently been found in France. With artwork that is apparently the oldest ever found, even still, I think, and it was about 35,000 years old. We gave early ancestors such little credit, but there very clearly was a lot going on upstairs. They even found a hollowed-out animal bone carved into a pentatonic scale. Mind blowing.

Several years ago I took a summer course on ancient Greek theatre that involved traveling around Greece and visiting various theatres and archeological sites, and I will never forget what it was like being in the theatron at Epidaurus while my professor stood in the orchestra and performed a section of the Iliad in ancient Greek. It was utterly eerie and the closest thing I've ever experienced to time travel (and also the site is chock full of very friendly cats, 10/10). Thanks for the fascinating video!

I sang at Epidaurus, very cool! A visiting professor clapped around the stage while we sat far up the stands, the closer his hands got to the centre of the stage, the louder it seemed. When his hands were just over the centre of the stage, it was like someone clapping in your ear!

I also sang inside the beehive tombs of Mycenae, where the sound was amplified incredibly! A funeral held inside one must have been an experience!

That's one of mankind's biggest strengths: As long as we had enough experience with it, we don't need to understand HOW something works to harness and use it. how acoustics or farming worked on a scientific level was not neccessary to know, we had MILLENNIA to find out how to build and farm and THEN we had centuries to find out WHY we did it that way

There’s plenty of reason to doubt that the greeks knew about the physics and science involved with the theatre on a technical level, but I would say that the observation of two similar sounds cancelling each other out or amplifying one another based on their distance from one another is something anyone with the need to look into that, such as an acoustics architect, could reasonably find with some simple experiments.

If this is the case, then said archetect would have lined the steps at the distance he found best for reducing background noise. This would be my hypothesis, which obviously needs evidence to support it (which is probably non-existent).

C. Romperer

4y↑2

I was thinking either that, or more often, ancient architects would mimic eachothers work, so if one just happened to build a theater that amplified the right sounds, others would be more likely to copy it, and over time they'd improve.

Physical physical Acoustics are absolutely fascinating! I was in a conference that was cohabiting with a physical Acoustics conference and they described to me the way you could set up a sparsely-populated gallery where you had a hyper Sonic emitters (above human hearing) along 2 walls and the interference patterns would be encoded with a descriptive signal (voice/music)for the exhibit you were in front of at the time!

I had the pleasure of clapping at Chichen Itza in 2012. Also, next to the temple is a Pok-Ta-Pok court, where they played a Mayan sport that requires bouncing a ball off of the player's hip through a hoop; apparently, the ball bounce echoes on the temple and sounds even more like a bird than a clap does.

So these ancient structures created by ancient peoples with astounding precision in their stonework produce unusual acoustics, in one case producing a sound very similar to the call of a bird sacred to the builders and we wanna say we can't be sure if the acoustics were intentional or a happy accident?
I know the scientific process is about having an idea about a thing and then doing every test imaginable to prove the idea wrong or right, with many scientists being more excited about being proven wrong over being proven right, but it seems a little silly to me to think that these builders built these amazing structures and just accidentally produced these unique acoustical phenomena.
Especially when some of these sites are conducted in the name of religious worship. Nothing motivates a people like faith and the ancient people were a lot more sophisticated than modern times want to give them credit for.

In the end it's still speculation. You can't say it was on accident or on purpose for sure without some proof.

Patrik

You can not prove an idea (read: theory) right.

But I am with you on this. These ancient people had the same physical and mental capacity as us. They didn't have electricity, no internet, no cranes, but they sure had a lot of knowledge and this was their entertainment. These theaters and places of worship were their youtube/TVs/cinemas.

Of course they put all their brain power into building them to get the best experience. Just like we put all our brain power into getting the best sound quality from tiny headphones and the most fluid animations on the most brilliant, colorful displays in the palm of our hands and what not.

Joe Scott recently made a video where he analyzed how long our human traces would last. Guess what: After just about 10k years, you'd barely recognize that we even existed. So I think it's plausible a LOT of the lifestyle and knowledge and even artifacts from ancient times are completely missing, so we assume all they had were those stone structures that we can see today. There was way more. Here's the video: https://www.youtube.com/watch?v=xtJ49gXWwA0

While it’s unlikely the ancient folks who designed and built these sites knew the underlying physics at play to the same level we do, there’s little doubt in my mind that the acoustics were intentional. I would posit that many of the phenomena were accidentally discovered at first, and then once the geometries involved in creating them were understood, the civilizations that made them reproduced them at a larger scale. Bear in mind that most ancient ruins that have survived the eons were important, culturally significant structures and were built to higher standards, with more detail, better materials, and superior craftsmen than typical structures. The stone monuments survive, but the average family’s wooden house does not. It’s logical for these central structures to have intentional, special acoustical properties just as we do with important cultural venues today.

Tl;dr: It’s difficult to right off special acoustical phenomena popping up at important ancient cultural sites and monuments across civilizations and time repeatedly as being accidental.

Sonja Johnson

4y↑6

I agree. They may have simply experienced the effects in natural caves and so on, and they might never have had quite the kind of technical terms we have now. But they would have known the basic "this shape of a wall makes the voice echo" quite well. And, because these were all "public spaces" in a sense - spaces intended for important social/emotional/religious happenings - they would indeed have had the best minds, the best hands, the best materials available.
I would add to this - every one of these examples were designed to mystify, to enhance emotional responses AND to inspire a deep sense of awe and wonder.
We already know that stone monuments of all sorts were basically always intended to inspire the viewers. Whether that was inspiring awe and respect for a king, or awe and fear of a deity, I think it's plain that a theater, a temple, a henge ALL share in common the wish to evoke strong feelings in their audiences. And so some portion of these designs is literally (sorry for the word play) for effect: precisely designed to get precise effects on the sounds made. Think about it: the builders and the priests were almost certainly better educated than the average layman in attendance at a temple. The layman would have had NO idea about the secret air ducts or special geometries or anything else. How much more powerful would a given event be if you experience sounds like no others you hear in your everyday life? Sounds you CAN'T explain for yourself? If the whole temple plaza is "singing" - could you not believe that the gods themselves are communicating with you? If you knew none of our modern day physics and science, and you heard that, would YOU believe it was just a dude with a conch shell in the basement? Of course not! (To be honest I probably wouldn't believe it even knowing some basic science!)
But these are REALLY great examples of some of the best minds of their respective times. Us humans are pretty nifty from time to time. And we sound good too!

[03:42] Converting a sharp pulse into a long drawn chirp is a process that has applications in things like radar signal processing. Interestingly, electrical signals are often converted into acoustic ones and processed using these same principles in what are called Surface Acoustic Wave (SAW) devices.

You left out that amazing curved bridge that projects whispers while at the same time canceling screams. It's fascinating. Also there are some caves in Turkey I think that are acoustically exceptional as well. My parents are musicians and Bach is someone I'm fairly familiar with. He wrote a piece called The Well-Tempered Clavalier in A440. My dad tells me there's something perfect about this exact frequency and key. He's a talented musician, but unfortunately a crappy teacher so his explanation of it made no sense to me. But I'd love to know who discovered that!

We should make a temple with modern technology for the express purpose of having the raddest acoustics in the universe.

Considering that Pythagoras (c. 570 - c. 495 BC) lived prior to the building of Epidaurus I would suspect that the Ancient Greeks had a handle on theatre acoustics like this. He was pretty instrumental to discoveries in music theory, the math of frequencies and noise cancellation.

Mind Palace TruePartyKing

It seems like the more we analyze the people of the ancient past, the more we realize how brilliant they actually were

Sound engineers often create claps and sharp transients by quickly dropping pitch using an envelop to control amplitude. The chirp of the clap is opposite to that technique.

bimt

cool information as always. Besides the quetzal sound, on the same there is a massive sports field ( the one they use their hips to hit a ball). They have accoustics similar to the greek theatre shown. Basically you can stand in front and very away from the lets calls the referee chair and you can hear loud and clear . yep from very far away you can hear now tourist chatting if they are located on that spot... if they moved, then you cannot hear hear them now. pretty cool a visit to chichen is very well recomended.
Also I remember watching an old probably early 2000 discovery channel doc on regards to the quetzal sound, they matched both soundwaves almost perfectly. pretty cool

Now I wish we could have a stonehenge replica to visit and experience this for ourselves. Don't touch the original, just build another one, preferably several ones so people wouldn't have to travel long-distance but can experience it in a less polluting way than having to board aircraft.

This reminds me of growing up in PaloDuro Canyon.
There is a beautiful outdoor stage there.

These places must have been truly amazing to ancient peoples.

Looking into the wild stuff the Inca pulled off, I think it's safe to say it was on purpose.

Aren't there some funky structures in Egypt that also do weird sound stuff?

menkiboj

i experienced the chichen itza effect many times when walking by a long wall made out of trapeziodal sheet metal, every step or clap sounds like that
i used to walk by a company that was built with it

Been to the Stonehenge replica, can confirm, so cool.

theres an expirement ive always wanted to do with these ancient acoustic sctructres. gather 30 or so professional singers, and have them all harmonize in various ways and see how they interact with the structures. they were clearly designed with something involving sound being used, and how else can you find out besides trying it literally?

I think this is one of the coolest scishow episodes ever

Icestorm_rb

Imagine going to these places and making Impulse responses from them. It would be an interesting experience and would make some interesting reverbs and sound effects! How useful would they be? No one really knows! It might actually be really cool!

I was hoping you'd do #2, the Chichen Itza one!

Sam bo

the throne hall at Persepolis apparently also had unique acoustic and light amplifying design considerations. Highly polished and densely packed colonnade and a very high ceiling allowed for the king to speak to a large audience without having to raise his voice.

Abhay Gupta

many temples in India have very unique acoustic properties to their architecture, like temple with musical pillars or the hall where one can hear slightest whispers of people on the ground floor while standing on top floor. it can have a video of it's own

Been on Epidaurus and on other ancient greek theaters and as a greek I have to say that I am very proud of these structures and how they have been so well preserved during the centuries! Plus the acoustic is amazing!

The range of human hearing ranges from 20hz to 20,000hz. It is most sensitive in the range of 2000-5000hz of which 500hz is a common multiple.

As you say in the video, most noise is below 500hz which would make it an ideal roll off point for unwanted frequencies. As the 3 octaves above that cutoff contain the frequencies we are most sensitive to.

I remember taking the tour at Hoover Dam and freaking out the tour when I would hum and set up a standing wave in the tunnel. I small hum at the right frequency made a very loud noise. The Hoover gods were very kind that day... :-)

I remember going to chitchen izta (Ik I just butchered that spelling), hearing that noise again just sent shivers down my spine. So cool but so strange. It’s unreal.

I wanna know when they started to realize they could accomplish these acoustics with structures

Actors in the ancient Hellenic world also wore masks with built in megaphones. It probably helped to increase the frequency.

I've been to Epidaurus, my Latin teacher dropped a small stone on the stage area while we all sat at the top and we could still hear it.

4:18 I wonder if the veneration of the Quetzal bird was inspired by the echo of the pyramid instead of the other way around.

I went to a coffee shop with large glass walls and it was like a nightmare soundwise.
A thousand times noisier than it would have otherwise been.

PyroGiz

There's a beautiful amphitheatre in Cyprus called Kourion which is built on top of a cliff, if you're ever in Cyprus you should definitely go and take a look - they still host concerts and plays there afaik.

Edit:presumably with more to come)
With the pyramid at Chichen Itza - did anyone check to see how sounds are when they're coming down from the top? Would it have distorted the voice of whomever would stand up top?

durwin pocha

The voices come from everywhere at once, in Stonehenge. That is interesting.

Forrest Judd

It is beyond comprehension to undermine these ancient civilizations intelligence and awe-inspiring structures just because we no longer possess the same knowledge they once had. Instead of trying to deny their intelligence, we need to aspire in achieving our own intelligence to the same level.

Im still under the belief (and have been for about a decade) that atleast the cultures with pyramids, had technology based on using sound... Such as lifting things to move them easier... And this video has made me think its even more possible. I won't go into conspiracy or anything but... Sound doesn't travel through empty space, but light does, and there are many religious references that make it seem like someone realised that.

JeffOf813

And it seems to be a big disconnect for the old and new testaments... Sound is used as a signifier of power or god a few times in the old, but then light is used as purity and power of god in the new quite a few times, which just so happens to be the part of the bible that also has a lot to do with the son of god... The sun of god? And lucifer is the morning star? That gets over taken by the light? Idk maybe im crazy.

Based off the comments in this video so far I’d say my hypothesis was correct. Most people who watch this channel are either actual students/scientists/engineers etc or stoners trying to get their mind blown 🤯

CoyoteCries

We have a similar thing to Chichen Itza in the town I live in. We call it the clap and squeak. Stand in the middle on this circle, clap, and it comes back as a squeak sound. You can only hear it if you stand directly in the middle, otherwise it just sounds like a clap.

jonnda

Was the theater of epidaurus tested full, or empty? Because there is a huge difference in how sound is reflected and/or absorbed, between stone surfaces and thousands of people.

Caphits

Ok, wow that temple sound thing sounds way way way too perfect to just be a coincidence. If those people were as clever as we are today (I'd argue they were likely more clever in many ways due to their upbringing), than I would not put it past them at all. You can even imagine a specific clap making device or ritual or something, calling in the sacred bird. I'm sure they had plenty of time to figure out this stuff, even just by stumbling on it without knowing the math or science behind it.
