Pyro Board and Resonance Mapping


The ability for sound to be represented in a physical form is pretty common. Our computers turn sounds from a mic into an mp3 made up of 010101010 and a similar process goes into etching onto a record or laser burning a cd. Sheet music enables a musician to recreate sounds. Those are a type of translation. Another type is something a little more literal and is more of a "transfiguration" or a literal manifestation of sounds into a physical form. 


If you put salt or sand under a speaker and then change the frequency it will arrange into different shapes - depending on the tone. One of the more interesting aspects is that it is possible through these shapes to encode sounds into a visual image. It also has implications into synthestasia and that if sounds have a direct corresponding shape(s) then it could be possible that when we see them it activates some type of subconscious understanding of them. Meaning that if you presented the various shapes in a specific order you could potentially - by looking at them in that order - mentally hear what they represent. Since these shapes are not just "Symbolic" but are created directly - they have a type of universality. So unlike, say, different languages, they are rooted in the physical laws of the universe and not subjective interpretations or depictions. It's the difference between using a word to demonstrate something or a photograph. One is an actual depiction of light and the other is more of a abstract concept. Or as Leonardo says about writing and painting: 


 "Now consider which is a closer examination of man, his name or his similitude? The name for man varies in different lands, and the form is mutated only by death. And if the poet acts through the senses by way of the ear, the painter [does so] by way of the more worthy sense of the eye. By these [comparisons] I only wish for a good painter to figure the fury of a battle, and for the poet to write something about it, and for both [of these battles] to be put before the public. You will see which will stop more viewers, which they will consider longer, which will be give more praise, and will satisfy more. Certainly the painting, a great deal more useful and beautiful, will please more." - Leonardo da Vinci

It's really interesting in itself but now it's been taken a few steps further!

These guys made a device that shows how sound waves form using fire!







Cymatics
"Cymatics (from Greek: κῦμα "wave") is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid.[1] Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency.
The apparatus employed can be simple, such as the old Chinese spouting bowl, or Chinese singing fountain, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Other examples include the Chladni Plate[2] and the CymaScope." - Link

It's thought that the carvings at Rosslyn Chapel demonstrate Cymantics

Archaeoacoustics

This is really interesting - it's the study of how ancient ruins could have acoustic properties. Similar to how old amphitheaters were set up so that the audience could easily hear the people on stage. Or how ruins were aligned with the sun and moon on certain days - which acted like a calendar. This studies how the structures are arranged to work with sounds.

Archaeoacoustics – The Sounds of Ancient Places - Link
"Many of us like to visit the ruins of ancient monuments and temples, trying to picture what went on at these places. But it tends to be a silent movie running in our minds. Fortunately, archaeologists are at last beginning to realise that ancient people had ears, and the various soundtracks of antiquity are beginning to be investigated.




The term “archaeoacoustics” simply means the study of sound in archaeological contexts. There are two basic ways this can be done, by exploring natural sounds and acoustics at monuments and other sites, or by investigating and measuring the acoustic parameters of a place by use of electronic instrumentation."
