Flattr this!

this edition of framework:afield, the 4th in a series produced by members of the world listening project, has been produced in the u.s. by greg o’drobinak, and is entitled worlds unheard. for more information, see http://www.worldlisteningproject.org. the producer’s comments:

Worlds Unheard is a program that brings to the listener a variety of sound experiences that are far beyond our capacity to hear them in everyday life. Some sounds require translation, like the extremely high frequency utterances of bats or the extremely low frequency vibrations of the earth, in order for us to hear them. Others simply need to be picked up with the appropriate transducers and then amplified directly for us to hear. This is only a small sampling of an immense world of sound that is available for us to discover and enjoy.

Ultrasound / Raimund Specht / bats: Noctule and Pipistrelle

A recording of ultrasonic utterances from two different bats brought into our range of hearing via the Avisoft software package.

Living Cells / Anne Niemetz / sonocytology (sound from cells)

The sounds made by the microscopic movement of cells rendered audible via the atomic force microscope. A tiny cantilever rests on the cell and picks up its vibration much like a phonograph needle.

Living Cells / Joe Davis / sounds of cell movement

Groups of one-celled organisms whose movement is rendered audible by Joe’s Audio Microscope. It uses a dark-field illumination technique with a coherent light source. This light is modulated by the movement of the cells and converted to audio by an amplified photo-detector.

Structure Transduction / Greg O’Drobinak / pneumatic HVAC steam valve

The sound of air and steam picked up with a geophone placed on the pneumatic control pipe in a machine room. The geophone is a sensitive electro-magnetic transducer normally used for recording seismic events, but it is also useful for recording other small vibrations.

Structure Transduction / Jodi Rose / mix of bridge sounds: “Norse Bridge Apocalypse”

Sounds from the cables and superstructure of bridges picked up by various piezo-electric transducers, amplified and woven into a composition.

Structure Transduction / Mark Bain / geosensor renderings of structural sounds

The physical vibrations within the architecture and furnishings of a large testing laboratory picked up by an array of geophones and amplified directly.

Seismic Waves / John Bullitt / seismic waves passing through the earth

A rendering of seismic vibration data of several areas of the earth greatly accelerated in time and amplified.

Electromagnetic Waves / Christina Kubisch / sounds of electromagnetic induction

The electro-magnetic fields of our urban environment are picked up via stereo induction coils built into a custom headset and amplified without modification.

VLF Sferics / Greg O’Drobinak / atmospheric whistlers

Whistlers are electromagnetic waves in the audio frequency range produced when the energy from lightning storms is dispersed and diffracted in the upper atmosphere by the earth’s magnetic field. These waves (sferics), literally “nature’s radio”, are picked up via one magnetic (H-field) loop antenna [left channel] and one electric (E-field) whip [right channel] antenna and amplified for us to hear. VLF is a term used to classify radio waves: Very Low Frequency

VLF Sferics / Stephen McGreevy / whistlers and dawn chorus

Stephen uses a combination of H-field and E-field antennas to pick up a great variety of sferics. These natural radio waves are amplified directly for us to hear.

EVP [electronic voice phenomena] / Ray Cass / paranormal voice recordings

EVP uses radios and tape recorders to capture the disembodied voices of humans past. Ray is generally regarded as a notable master of the technique. There is no translation or modification of the audio signals that are picked up; they are simply recorded without modification when they occur.

EVP [electronic voice phenomena] / Michael Esposito / paranormal voice recordings

Michael is a contemporary EVP and paranormal investigator. We hear some of his private EVP recordings, untouched from their initial capture.
