论文摘要
UDU是一种传统的尼日利亚打击乐器，可以将其视为带有两个光圈的Helmholtz谐振器。我们使用简单的两粒子机械类似物来研究这种谐振器的行为，并发现该模型很好地描述了UDU声学的主要特征。
The udu is a traditional Nigerian percussion instrument that can be thought of as a Helmholtz resonator with two apertures. We use a simple two-particle mechanical analogue to study the behaviour of such a resonator and find that the model describes quite well the main features of udu acoustics.
