Each segment of the Spectral Mosaic indicates a sound within the layers of high tide. Ordinary sound waves measure volume but spectral frequency also measures the different pitches & frequencies within the layers of sound. Therefore it is possible for us to see the sounds we can not hear - even those masked by the louder sea sounds.
In short, sound is textured and 3 dimensional. The slides show the sounds from the spectral frequency that Cheryl can not clearly hear due to her hearing impairment. It is these that inspired her research & informed the notion of a Spectral Mosaic as Contemporary Art in the Public Realm, extending access to the natural world.
Based on this research, Cheryl is currently in design consultation with a glass artist, mosaic artist & digital print artist, exploring ways of creating an environmental visual braille.
