Para a realização de uma sincronização induzida por ruído em ambiente natural, é realizado um estudo experimental utilizando o circuito oscilador Van der Pol. Nós nos concentramos nos sons acústicos como uma fonte potencial de ruído que pode existir na natureza. Para imitar um ambiente tão natural, sons de ruído branco foram gerados a partir de um alto-falante e gravados em sinais de microfone. Esses sinais foram então injetados nos circuitos osciladores. Mostramos que os circuitos osciladores dão origem espontaneamente a dinâmicas sincronizadas quando os sinais do microfone estão altamente correlacionados entre si. À medida que a correlação entre os sinais do microfone de entrada diminui, o nível de sincronia diminui monotonamente, implicando que a correlação de entrada é o principal determinante para a sincronização induzida por ruído. Nosso estudo fornece uma base experimental para sincronizar relógios em redes de sensores distribuídas, bem como em outros dispositivos de engenharia em ambiente natural.

Abstract: Towards realization of a noise-induced synchronization in a natural environment, an experimental study is carried out using the Van der Pol oscillator circuit. We focus on acoustic sounds as a potential source of noise that may exist in nature. To mimic such a natural environment, white noise sounds were generated from a loud speaker and recorded into microphone signals. These signals were then injected into the oscillator circuits. We show that the oscillator circuits spontaneously give rise to synchronized dynamics when the microphone signals are highly correlated with each other. As the correlation among the input microphone signals is decreased, the level of synchrony is lowered monotonously, implying that the input correlation is the key determinant for the noise-induced synchronization. Our study provides an experimental basis for synchronizing clocks in distributed sensor networks as well as other engineering devices in natural environment.
