Did you know that ancient acoustics can give us a peek into the past? Many ancient buildings & structures have incredible effects on sound waves, suggesting that early cultures built these spaces that way for a reason. By studying these ancient sites we can learn new things about the past and the people that lived there, thousands of years ago! Join Hank Green for an amazing acoustic adventure back in time.

This phenomenon has been used by organ builders since the late 18th or early 19th centuries. If you don't have room (or funding) to build a 32' or 64' stop, you use shorter pipes that sound the harmonics that would be produced by longer pipes. Your brain just fills in the missing fundamental. They're called "resultant stops." Psychoacoustics is a fascinating field.

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.

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!

How could they not understand the physics. Sorry but you don’t start carving and laying stone unless you have a design and a plan.

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.

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: kzfaq.info/get/bejne/rtp6Z5yYvb3bcWQ.html

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).

A few years back, I was privileged to watch a performance of Carmen in the large Roman Amphitheatre, in Verona. The whole event was delivered acoustically, without the use of electronic amplification. The sound quality was excellent.

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

The ball court at Chichen Itza has a really cool acoustic element. There are throne seats on either end of the court. If you talk to the back wall of these areas, your voice will heard clearly on the other end. I have experienced this myself when I visited.

as an audio engineer, sound designer, singer and voice over artist, a few things: 1) resonance is everything. a couple mentions isnt enough. 2) talking about specific individual frequencies without also referring to the harmonic series is quite sophomoric. Frequencies that invoke brain activity in language vs emotion is ... just not a thing. Language is all the frequencies, emotion is all the frequencies. Sine waves (waves of singular frequencies and no harmonics) don't occur in nature, so our brains didn't evolve to respond to them specifically. 3) wind produces ALL frequencies, just at different amplitudes (see pink noise vs white noise). whispering is almost exclusively 1.5 kHz and higher. 4) All human voices, male and female, of all voice types produce fundamental frequencies below 500 Hz. The harmonic series accounts for vowel intelligibility. consonants are almost exclusively 4kHz and higher.

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.

Regarding Epidaurus: Wouldn't the sound waves mainly be bouncing off people in a packed theatre? The way Hank talks about how sound is reflected by the steps makes it sound like the theatre was constructed to be used without an audience.

The original chamber for the US House of Representatives was like the stone hinge example-is, it still exists and you can take a tour to see it. It’s shaped to amplify the voices at regular speaking volume so that you can hear someone in the opposite corner as crystal clearly as if they were right up in your face. It’s eerie and effective.

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.

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

It really seems like the ancients from the deep past are trying to communicate with the future simply via the mathematical patterns expressed via their architecture; astronomical alignments that model (among other things) procession and size of the earth, acoustics, golden ratios, cryptic messages or "we exist," fibbanacci sequences and more all stretching back as far as ten thousand years ago or more. It's really fascinating and continuously throwing a wrench in our understanding of the human story. To me it's most exciting frontier of discovery on our planet.

Another example of a waveguide is a section at Grand Central where you can stand in the corner and speak and a person at the opposite corner will be able to hear you quite clearly. I remember trying this out as a kid and being amazed. Not an ancient structure but still pretty cool.
