Polyphonic Overtone Singing Demonstrated by Anna-Maria Hefele

This is a great video of polyphonic overtone singing by Anna-Maria Hefele, where she precisely demonstrates the almost inhuman ability to create a harmony of two notes at a time using a single breath. Overtone singing is the same technique used by Tuvan (or Mongolian) throat singers of which there are several other great videos to watch on YouTube. Also check out this demo by Alex Glenfield, or this clip lifted from I’m not sure where. (via Stellar)

The Sounds of Aerobatic Paragliding

The Sounds of Aerobatic Paragliding stunts sound paragliding

First: put on your headphones or turn up the volume, otherwise the beauty of this clip might be lost. Sounds of Paragliding is a new video from director Shams (previously), and sound engineer Thibaut Darscotte who took special equipment into the skies above France to record the sounds of Théo de Blic’s aerobatic paragliding. Instead of amping up the music and intensity like so many high-speed stunt/wingsuit/skydiving videos these days, Shams instead slows everything down to focus on only the sounds created by Blic’s parasail whipping through the air at incredible speed. It doesn’t really get going until after 2:00, but is completely worth it.

Artist Creates Digital Life-Forms that Respond to Archival Birdsongs

Artist Creates Digital Life Forms that Respond to Archival Birdsongs sound birds 3d animation

Australian artist Andy Thomas creates what he describes as “audio life forms,” specifically 3D animations that respond to audio input. For these latest pieces he used archival bird recordings from the Netherlands Institute for Sound and Vision (in addition to one of his own recordings) to create these new digital sound sculptures that animate in different ways in reaction to the songs of each bird. Thomas uses more software tools than we could reasonably share here, but you can learn a bit more over on his website.

Artist Zimoun Creates a Roiling Ocean of Packaging Peanuts inside the Windows of an Art Museum

Artist Zimoun Creates a Roiling Ocean of Packaging Peanuts inside the Windows of an Art Museum sound kinetic installation

Swiss artist Zimoun (previously) just unveiled a large installation inside the windows of the Museo d’Arte di Lugano in Switzerland. Titled 36 Ventilators, 4.7m3 Packing Chips, the kinetic artwork relies on large fans that perpetually blow clouds of packaging peanuts against the museum’s broad windowframes. At night the effect is especially eye-popping as it appears the entire space is filled with a turbulent white sea. Via bitforms gallery:

Using simple and functional components, Zimoun builds architecturally-minded platforms of sound. Exploring mechanical rhythm and flow in prepared systems, his installations incorporate commonplace industrial objects. In an obsessive display of curiously collected material, these works articulate a tension between the orderly patterns of Modernism and the chaotic forces of life. Carrying an emotional depth, the acoustic hum of natural phenomena blends effortlessly with electric reverberation in Zimoun’s minimalist constructions.

Another recent Zimoun piece is an installation at Orbital Garden in Bern using packaging paper and motors that similarly creates a water-like effect. (via Creative Applications which just launched a new print magazine, HOLO)

Pyro Board: An Audio Visualizer Created from an Array of 2,500 Flames

Pyro Board: An Audio Visualizer Created from an Array of 2,500 Flames sound science fire

So here’s a thing to never try at home. Derek Muller from the very fine science video blog Veritasium visits with a team of “phsyics and chemistry demonstrators” who built this ridiculous sound board that demonstrates the effect of sound waves traveling through flammable gas. The first half deals mostly with how it works, around 3:38 it turns into pure music and fire.

Noise: A Visualization of Sound through Stop Motion

Noise: A Visualization of Sound through Stop Motion stop motion sound animation

Nearly three years after sharing the trailer for their short film Noise, polish animators Katarzyna Kijek and Przemysław Adamski (previously here and here) have just released the full version online for the first time. The short was screened at more than 60 film festivals globally over the last few years, receiving numerous awards and accolades along the way. I won’t spoil it for you, but the innovative short explores the visualization of sound through stop motion animation. Via their website:

[Noise is] inspired by the theoretic work of George Berkeley and basics of synesthetic perception. It’s a game of imagination provoked by sound. Individual sounds penetrating into the apartment of the main character relieved of their visual designates evoke images distant from its origins.

You can see a few making of photos over on their blog. FYI: it gets a little dark.

One Step Closer to Hover Boards: Three-Dimensional Mid-Air Acoustic Manipulation

One Step Closer to Hover Boards: Three Dimensional Mid Air Acoustic Manipulation sound science device acoustics

While we’ve seen examples of objects suspended mid-air using quantum levitation and acoustic levitation, a team of three Japanese engineers from The University of Tokyo and the Nagoya Institute of Technology recently unveiled an ambitious device that uses sound waves to move objects through three dimensional space. The machine uses four arrays of speakers to make soundwaves that intersect at a focal point that can be moved up, down, left, and right using external controls. You would think such machine would be extremely loud, but according to one of the engineers the device uses ultrasonic speakers and is almost completely silent. You can read more about it right here.
