Micro Listening Workshop
DAVID DUNN, composer
The Micro Listening Project is an interdisciplinary art and science strategy for increasing the monitoring of our environment through sound. It hopes to provide new inexpensive technologies that can facilitate an increase in our collective environmental sensitivity and discovery of unknown natural and human made phenomena, providing novel tools for sound artist, and contributing towards practical environmental problem solving
The project focuses upon the design of inexpensive but highly effective audio transducer systems for bioacoustic and sound art monitoring of otherwise hidden aspects of our auditory environment that are not audible through the use of conventional microphones. In addition to these technological advancements for listening, the project seeks to document a wide diversity of sound worlds for both demonstration of the transducers and general aesthetic revelation of our environment. Precise instructions on how to use and construct these devices will be part of this workshop. The devices are designed to allow as wide a distribution of their use as possible by both amateurs and professionals
Ideally, the workshop lasts 8 hours over two days which allows for an in-depth exploration of the potential uses of each transducer as well as discussion about alternative variations on each design. The presentation is filled with a great variety of recorded examples that demonstrate the qualities and capabilities of the micro-listening tools.
