listening closely

Mhz: A unit of frequency equal to one million cycles per second.

"...allows the audience to handle and scan the objects to activate audio triggers."

This is just a wireless triggering scheme... not really what I'm thinking about at all...

TAGGED
//Five new works by artists working with RFID technology as part an
ongoing project produced by [ space.media.arts ]// 

In this exhibition, the artist collaborative **Louis-Philippe Demers and
Philippe Jean** are working with local shop Hollywood Convenience
electronically tagging their grocery items to produce the artwork iTag.
Using a portable music device, available to pick up from the exhibition,
shoppers can listen to music generated from the grocery aisles.

“Natural Radio”, a term coined in the late 1980’s by California amateur listener and
researcher Michael Mideke, describes naturally occurring electromagnetic (radio) signals emanating from lightning storms, aurora (The Northern and Southern Lights), and Earth’s magnetic-field (the magnetosphere). The majority of Earth’s natural radio emissions occur in the extremely-low-frequency and very-low-frequency (ELF/VLF) radio spectrum specifically, at AUDIO frequencies between approximately 100 to 10,000 cycles-per second (0.110 kHz). Unlike sound waves which are vibrations of air molecules that our ears are sensitive to, natural radio waves are vibrations of electric and magnetic energy (radio waves) which though occurring at the same frequencies as sound cannot be listened to without a fairly simple radio receiver to convert the natural radio signals directly into sound.

Examples of projects which make audible the usually unheard transmissions, provided by Andrew Austin...

David Rosenboom ("Brainwave Music") and Alvin Lucier ("Music For Solo
Performer") both did projects in the late 60's and early 70's using
Alpha-brainwaves to control sounds, or systems to create music.

Electronic Voice Phenomena.....in other words, voices (sometimes thought to
be of the dead) appearing in electronic emptiness, such as on blank
cassettes, or TV/radio static - see the following for more information:

The Conet Project - an audio project focusing on shortwave radio "spy"
stations - covert transmissions intended for agents in the field. Very
popular during the Cold War, and now apparently re-appearing in Arabic
variants.....

You can download (legally, and for free) the content of the 4-CD set, and
it's accompanying booklet, here:

VLF (Very Low Frequency) and ELF (Extremely Low Frequency) radio signals
(also known as "Natural Radio") - from natural and/or man-made phenomena
(both the U.S. and Russia experimented with ELF transmissions from
submarines during the Cold War).....Stephen P. McGreevey is one of the
authorities on this subject, he has his own site, and also has a 2-CD set,
and booklet, that can be downloaded freely....:

Alan Lamb - Australian composer noted for his works where he contact-mic'ed
telegraph wires in the remote Australian outback, to produce music.....:

There's also things like the (mostly) Japanese "Onkyo" movement - where
sounds are produced using equipment like mixing boards with no other devices
input into them (Nobekazu Takemura and Sachiko M are 2 names to seek out in
this area), and composers such as Rafael Toral, who have made works using
feedback loops from linking together effects pedals without any exterior
sounds (which, incidentally, harks back to David Tudor, and pieces like
"Rainforest" and "Microphone" which used similar tactics in the
1960's.....).
