Sonic Structure I is an installation composed of hand-Jacquard woven cotton and copper, and an electronic circuit that measures changes in electro-magnetic frequencies as a viewer touches the cloth. As the changing frequencies enter an audible range they are heard through the speakers mounted on the wall near the weavings. The patterning on the cloth is created from measuring frequencies of a pre-recorded sound and building a matrix from the derived values that correspond to the number of warp threads on the Jacquard loom used.
