TTBOOK: The Art of Noise Noah Vawter demonstrates a portable listening device that converts the sounds around you into a form of music. Bart Kosko explains the science of noise. Paul Hegarty is really into Noise/Music. Caryl Owen fears the noises in her head. Anne D. LeClaire spends two days a month in complete silence. Noah Vawter is a Research Assistant and PhD candidate at the MIT Media Lab. He talks with Jim Fleming about and demonstrates his "Ambient Addition." It's a portable listening device you wear like a walkman that converts the sounds around you into a form of music.

Bart Kosko is a professor of electrical engineering at USC and the author of "Noise." He explains the science of noise. And we hear lots of examples.

Paul Hegarty is a lecturer in Philosophy and Visual Culture at University College Cork in Ireland. He's also really into Noise/Music and is the author of "Noise/Music: A History." He talks with Steve Paulson about the Japanese contributions to the genre. And we hear some.

TTBOOK's Technical Director, Caryl Owen, provides an essay on her lifelong fascination with sound and technology, and her fear of losing her hearing to the condition known as tinnitus.

Anne D. LeClaire is the author of eight novels and "Listening Below the Noise: A Meditation on the Practice of Silence." The book describes her efforts to spend two days a month in complete silence. She talks with Anne Strainchamps about the book, her practice and its inspiration. And we honor her with a second or two of silence before the close music starts.
