The patterned data produced by reaction-diffusion systems is used to create a naturalistic soundscape in the piece cicada.
Each cicada either sings, chirps, clicks, or is silent depending on its environment and the weather conditions which are modelled by reaction-diffusion patterns.
The third level of the time tree structure is used to determine note and rhythmic durations of individual cicadas when they are active.
Loud though the cicadas may be, their occupancy of spectral space does not mask any of the other sounds.
Creating sustained tones with the cicada's rapid sequential buckling mechanism.
Values from each of the three levels are consulted to determine whether each cicada sings, chirps, or clicks, or whether it is inactive.
The next level of branches provides durational values for the series of episodes in which the aural behaviour of the cicadas is portrayed.
In some areas soil disturbance by emerging cicada larvae caused some seedling death.
