Sensory Dissonance and Sonic Sculpture





This research demonstrates how sensory dissonance can be used to visualize the sonic occupation of a given space. Sound sources can be arranged in three-dimensional space to produce an aggregate of atmospheric vibrations that are ultimately revealed as sonic sculpture.

Tools used to create, measure, and visualize sensory dissonance can be downloaded below. Each tool requires the software Max/MSP. To obtain the source code, please contact SonimmersionSupport.



Sensations of Tone: Sonic Immersion and Spatialization in the Allosphere




Sensations of Tone is an interactive audio-visual installation presented in the Allosphere at the California NanoSystems Institute (CNSI) building at the University of California Santa Barbara.

The Allosphere is a 30 foot diameter spherical enclosure built inside of a three story near-anechoic chamber. The spherical enclosure is completely illuminated by 26 projectors and enveloped by 140 speaker elements, generating audio and visual immersion into virtual environments.

The piece, Sensations of Tone, is an interactive installation that allows users to create sonic environments via exploring various levels of sonic roughness. The piece has its core lying in theories associated with sensory dissonance. In particular, algorithms are employed that allow the user to control the amount of roughness present in a given sonic spectra and that allow the user to select optimum combinations of the spectra. Visuals projected onto the spherical screen communicate to the user the source location of each sound along with the sensory contribution to the environment.

Using the control interface of an iPad, sonic spectra can be precisely focused or randomly dispersed among the Allosphere’s spherical array of 140 speaker elements.  The user sculpts the sonic atmosphere by adjusting volume, roughness level, pitch ratio, and panning for each of three voices present.
