Structure-borne sound

On the "healing sound rooms" tip - Have you done any experiments with Colundi and structure-borne sound - where you turn the loudspeakers so they push sound into the walls, making the physical structure of your room / house vibrate, making sounds refract and emerge in different places?

You can use the physical structure of your room as a prism for frequencies - sound travels faster through a solid than through air, and sound waves do the same thing as light where different frequencies move at different speeds. You can use these techniques to create a multi-dimensional sound sculpture where different frequencies hit you depending on the exact position of your head.

Here is an interesting bit from a eulogy for Maryanne Amacher a couple years ago -

"For someone so dependent on technology, specifically high-end loudspeakers, she was entirely uninterested in the sound the speakers make when hearing them directly. She made great effort, and had success with developing an approach to "structure borne sound", hiding speakers in acoustically coupled locations beyond the presentation space (or inside an enormous plastic lion, as was the case in Berlin recently), and by firing speakers into walls and floors rather than straight into the air. She talked about what she was doing as experimental acoustics and justifiably critiqued the "official" field as being in its infancy, relying on faulty tools of measurement rather than extensive first-person phenomenological research. At EMPAC she was using about 40 channels of audio, only about 4 were actually inside the theater! The rest were as far as three levels beneath, with carefully measured apertures created by doors, air vents, and so forth. She spent a full month at one point, moving one speaker at a time, slowly creating constellations of sound sources that could create sound masses, shapes, gestures, that were "her work" much more so than the sound material itself."

Amacher wrote about building "sound characters" in this way - creating sonic identities which would come out of the space in different ways, like spirits. Do Colundi frequencies ever come together to create multiple identities?

To put it another way - often the only way to hear you perform is when DJing "stereo" two channel works in club or festival environments, which might not necessarily be the perfect environment for appreciating Colundi. Have you ever built a sound installation in a different space?

Yes, and more are on the way.

Sound can levitate things. Sound can boil water. Sound can cut things like a laser. Sound can travel faster than the speed of light.

>Do Colundi frequencies ever come together to create multiple identities?

Yes, all the time.

>Have you ever built a sound installation in a different space?

Yes, many times; so far only tests and simulations. We have plans to build permanent intercontinental sound chambers. Different physical rooms with specific dimensions for colundi standing waves.

It feels really great to be inside a standing wave, it's like a new listening experience, a bit like hearing sounds under water, your whole body feels it and when you sing to the frequency it feels wonderful.

Colundi level 9 was released as a piece of land. We now have several different colundi nodes across the planet.

Did you ever try to type in colundi node to google maps?
