so I have two seemingly unrelated passions first one is architecture the second one is the power of sound the first one is my medium of expression the second one stems from a deeply held belief I have that the world as we know it is simply manifestations of vibrational frequency and I mean that on every scale this is one of the earliest images we have of the early Universe NASA researchers found that out of this chaos came an organizing pattern one of the first organizing patterns to the plasma Cloud it was a low frequency tone that
rippled through the plasma cloud and set into motion the creation of the galaxies and the universe as we know it today before matter existed the universe was already singing on the opposite end of the scaler Spectrum String Theory posits that at our most basic subatomic level we're all composed of one-dimensional strings whose vibrational frequencies define the laws of physics as humans we're not outside of this system we're interactive players in this process and we're very well tuned to do it the human ear enjoys three times more neural connections to the brain than does the eye
we can detect a vibrating molecule as low as 20 beats per second or 20 Hertz all the way up to 20,000 Hertz that's an order of magnitude of a thousand times roughly 10 octaves of sound that you can detect compare that against the order of magnitude of visual site which is only two or roughly a single octave which we know as Roy G Biv says as a designer we create architectural spaces which are de facto instruments they contain sound they manipulate it they can even create sound so we're tasked with a very powerful tool for
affecting human cognition and it was this passion that drove me in 2012 to embark on an international research Fellowship seeking out buildings that manifested specific Sonic phenomenon for the stated purpose of spiritual or transcend experiences I started with resonance and that's sympathetic vibrations which create amplitude and I don't know of a better pair of words than sympathetic vibrations our world could use more of it for this I traveled to the island of Malta in the Mediterranean and specifically to a 5,000 yearold underground Temple that was discovered under these houses in 1902 it's a three-story Temple
carved out of solid limestone in the Bronze Age and a particular interest to me was a space called The Oracle room archaeologists belied that this was reserved for the shaman of this religion the roof is painted in spiraling red paint which they suspect might be musical notation that we can't decipher the reason the Oracle room we're having battery issues there we go the reason the orac room is so special is because it's a perfect resonating chamber for a specific frequency 110 Hertz what makes it a resonating chamber the dimensions of the space are an exact
multiple of the wavelength of that frequency so as I stood in the space and I apologize for the lack of video the sensitivity of the sound site meant that they pattered me down down and I could enter with nothing so as I stood in the space and began to sing searching for that tone as soon as I hit 110 Hertz I knew it because the space came alive sounds suddenly surrounded you from every direction it sounded like there were people singing with you the intensity got so strong you could feel the vibration through your body
this is the tone of the hypium [Music] so what's happening why does it do this like I said when I start to sing my voice travels hits the wall and bounces back in sync with my remaining Voice Now constantly sound waves are interfering with each other and they usually muddy each other up when two waves are in perfect sync like this creates natural form of amplification called constructive interference or a standing wave that's what created the effect that I experienced so what that's the Sonic equivalent of an optical illusion basically right and that's the exact
question that a team of neuroscientists from UCLA asked in 2008 when they traveled to the hypogeum to study it what they found was the brain when exposed in the way the hypium does to that tone experiences shifts in the prefrontal cortex and creates a functioning asymmetry within the brain that's not dissimilar from the brain states of monks in meditation or Transcendent experiences and so archaeologists believe that there's a possibility the shaman of this religion were using this chamber as a literal gateway to the doors of perception if there's one critique of the hypogeum it's that
as soon as you stop the sound it dissipates for this we introduce reverberation reverberation can be considered the the amount of time sound lingers in a space after the source sound is gone and for this I travel to the baptistry of St John and pis two doors down from the Leaning Tower millions of people walk by it every day and very few know what it does a typical space such as this might have a reverberation time of one to two seconds but because of the architecture of the baptistry it enjoys A R A reverberation time
between 10 and 12 seconds about to play a video a single vocalist standing in the center of the space harmonizing a three-tone chord try and decipher what sound is coming out of her mouth and what sound is coming from the architecture around her [Music] w [Music] [Music] [Music] [Music] [Music] so if we can couple that sort of a immersive reverberation with the tones of the hypog we could create something powerful but what's happening there why is that happening if we take a look at the baptistry in both plan in section the first thing you should
notice is that in plan it's a pair of concentric circles and so as she starts to sing her vocal energy first interacts with the inner colonade and bounces straight back to her if we lay this out on a timeline we can start to map out the reflections of Acoustics within the space some of her voice travels to the exterior wall before returning back to her slightly longer travel time slightly longer reflection some of her voice gets trapped on the return trip between the outer wall and the colonade further extending that reverberation time and this happens
throughout the space in all the nooks and crannies the farthest traveling occurring heading straight up to the peak of the ceiling before returning back now keep in mind between reflection 3 and four Reflections 1 2 and three are repeating the process over and over again and it's this layering of sound that creates that extended reverberation time is if that wasn't enough a remodel to the building few hundred years ago added a dome which encapsulated airspace which acts as a resonating chamber holding those sympathetic vibrations and then returning them to the space even further extending that
reverberation time so now we've built a language of understanding on how to use architecture to make such a powerful Sonic space but how does one even begin to design that right you just start drawing circles or something and so for me I return to science and to sound this is a physics experiment in simatics which is the study of sound traveling through a medium this is hundreds of years old the the knowledge of this process it's simply a steel plate mounted onto a frequency generator with salt or sand sitting a top it as the experimenters
cycle through higher and higher frequencies you'll see that the sound reveals itself in formal Arrangements we were able to do this dozens if not hundreds of times and get out individual fingerprints each unique like a snowflake for various tones keep in mind these are two-dimensional representations of a three-dimensional process and as we started to study them I could decipher general rules to their organization as frequency increases so does the complexity of the pattern you can see that the lowest frequency at the top left is much more basic than the highest frequency at the bottom right
additionally every simatic pattern is symmetrical about an axis and this shouldn't be surprising because if you think about sound it's traveling in all directions at the same speed and so being a branch of physics it can be defined by math and if it can be defined by math it can can be put into the computer and so that's exactly what I did designed an algorithm in my 3D modeling software that allows me to recreate the simatic process in real time based on frequency wavelength amplitude and then I can tell the computer identify the symmetrical axes
and instead of mirroring as in 2D we start to think of orbiting for symmetry in three dimensions this allows me to now visualize the space spatial configurations of each of these unique tones and manipulate them in real time I apologize for the lagging computer it's pretty complex math but it's a fascinating process I can't get enough of it actually so this being said instead of dozens or hundreds of 2D prints I now had a process for iter iteratively creating dozens or hundreds of three-dimensional spatial configurations so I began to organize them based on frequency seeking
frequency based organizational patterns and thinking back to Pisa I thought why don't I start to group these things by harmonic frequencies so these are 3D prints of a harmonic Triad a B flat major to be specific what I was surprised by was that the tones that have a harmonic audible relationship also have similar formal Arrangements you can also you can almost imagine form a evolving into Form B evolving into form C and here's the tones that created these here's a name minor and it's created tones and my wife's favorite the c [Music] major so as
we start to Envision these as inhabitable space We Know by finally tuning the dimensional quality of this we can achieve the frequencies that we wish and by organized layered spatial complexity just like the P baptistry we can create hyperresonant and Hyper reverberant spaces these ideal sound baths if you will so I'm now working with the team who's envisioning these on a variety of scales from something small enough for one or people to share some time in to Sonic Exploratorium large enough for three or 400 people I'm also modeling more advanced mathematical processes through it and
it's opening new worlds that I had not even imagined with powerful spatial and formal opportunities and how can we use these spaces well like I said there's an entertainment aspect to this in a Sonic exploratory these could also serve as immersive Sonic therapy rooms for Sonic Immersion therapies that already exist for PTSD depression anxiety Parkinson's Alzheimer's these would also be powerful neurosci neuroscientific Laboratories into cognitive and sensory Neuroscience to further Advance our understanding of the power of sound on the brain and body but above all things this started and will always be for me a
chamber for Sonic meditation and a pure Temple of sound thank you
