声源的同步
Synchronization of Sound Sources
摘要：
声音的产生和相互作用是高度复杂的、非线性的和自组织的。早在150年前，瑞利勋爵就提出了以下问题：两个相邻的基频不同的管风琴管以几乎听不见的相同音高在一起发声。现代同步理论（M. Abel等人，J. Acoust. Soc. Am.，119（4），2006）。为了进行详细的定量研究，我们用一个电子扬声器代替了一个管道。我们观察到，即使是微小的驱动信号也会迫使管道同步，从而产生三十年的同步-这是我们所知的最大范围。此外，发现了管道的相互消音，这可以通过自组织振荡来解释，用于降噪的新方法。最后，我们开发了一个具体的非线性重建方法，产生一个完美的定量匹配的实验和理论。
英文摘要：
Sound generation and -interaction is highly complex, nonlinear and self-organized. Already 150 years ago Lord Rayleigh raised the following problem: Two nearby organ pipes of different fundamental frequencies sound together almost inaudibly with identical pitch. This effect is now understood qualitatively by modern synchronization theory (M. Abel et al., J. Acoust. Soc. Am., 119(4), 2006). For a detailed, quantitative investigation, we substituted one pipe by an electric speaker. We observe that even minute driving signals force the pipe to synchronization, thus yielding three decades of synchronization -- the largest range ever measured to our knowledge. Furthermore, a mutual silencing of the pipe is found, which can be explained by self-organized oscillations, of use for novel methods of noise abatement. Finally, we develop a specific nonlinear reconstruction method which yields a perfect quantitative match of experiment and theory.
