The effect of Air turbulence on sound and its Application to Musical signal Processing

The effect of atmospheric air turbulence on acoustic signals is modeled with the goal of producing a novel DSP technique for music and sound production. The building block of the turbulence model is called a ‘turbule’, a localized eddy with spherical symmetry. At the current stage of development, an operational model of a turbule is implemented in Matlab, and the effect of the turbule has been evaluated for a variety of atmospheric conditions. Analysis of the results from this model will pave the way for the creation of a digital effects module built on a network of turbules, one that can exaggerate the effect of air turbulence when needed for expressive purposes.
