Summary:
Synchronization phenomenon of uncoupled chaotic oscillators with additive common noise input have been investigated in previous studies. In our research, we introduce natural environmental noise as the additive input noise to the chaotic oscillators. The natural environmental noises are correlated in neighboring area, and we have already shown that the limit-cycle oscillators can be synchronized by such correlated noise. Our proposed scheme enables to synchronize unconnected real devices without any interactions between them. In this paper, we investigate feasibility of the proposed natural synchronization scheme on the Rossler system as a chaotic oscillator. First, we evaluate synchronization performance by adding the correlated Gaussian noise, and we show the possibility of synchronization of the chaotic oscillators by the correlated noise. We also introduce a real environmental noise, the environmental sound data obtained at the neighboring microphone devices, and we show that the Rossler oscillators can be synchronized by such correlated environmental noise.
