자연 환경에서 잡음으로 인한 동기화를 실현하기 위해 Van der Pol 발진기 회로를 사용하여 실험적 연구가 수행되었습니다. 우리는 자연에 존재할 수 있는 소음의 잠재적인 원인인 음향 소리에 중점을 둡니다. 이러한 자연 환경을 모방하기 위해 시끄러운 스피커에서 백색 소음 소리가 생성되어 마이크 신호에 녹음되었습니다. 그런 다음 이 신호는 발진기 회로에 주입되었습니다. 우리는 마이크 신호가 서로 높은 상관관계를 가질 때 발진기 회로가 자발적으로 동기화된 역학을 발생시킨다는 것을 보여줍니다. 입력 마이크 신호 간의 상관 관계가 감소함에 따라 동기 수준이 단조롭게 낮아지는데, 이는 입력 상관 관계가 잡음 유발 동기화의 주요 결정 요인임을 의미합니다. 우리의 연구는 분산 센서 네트워크와 자연 환경의 기타 엔지니어링 장치에서 시계를 동기화하기 위한 실험적 기반을 제공합니다.

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.
