Beside other transport properties of liquid foams, like the optical or electrical ones, the acoustics of liquid foams reveals a great complexity and non-trivial features. Here we present a review of recent experimental and theoretical results on how a sound wave interacts with either a macroscopic foam sample or with its isolated building blocks (films and Plateau borders). The analysis of the literature allows us to determine what is now well understood, what could be measured in foams by acoustics, and what are the remaining issues and perspectives in this research field.

液体泡沫的声学

除了液体泡沫的其他传输特性（例如光学或电气特性）外，液体泡沫的声学特性还显示出极大的复杂性和非平凡的特征。在这里，我们对声波如何与宏观泡沫样本或其隔离的构造块（膜和高原边界）相互作用的最新实验和理论结果进行综述。对文献的分析使我们能够确定现在已经很了解的东西，可以通过声学测量泡沫中的东西以及该研究领域中剩下的问题和观点。
