我们回顾了目前鸟类声音产生的生物力学定量模型。Fletcher（1988）提出了发声器官的定量模型。他将气管（即气管和支气管的一部分，有阴唇和膜）表示为一个单一的膜。这个膜就像一个阀门，在发声过程中迅速关闭和打开。这个模型可以作为解决比较形态学和生理学问题的基础。最近，syrinx被建模为一个简单的改进振荡器。声音的许多特征被捕捉得非常好。然而，参数值并不能代表syrinx实际材料特性的分布。这些模型展示了描述声音信号基本动态所需的最小参数数量。此外，我们还讨论了建模未来可能有趣的方向。
We review current quantitative models of the biomechanics of bird sound production. A quantitative model of the vocal apparatus was proposed by Fletcher (1988). He represented the syrinx (i.e. the portions of the trachea and bronchi with labia and membranes) as a single membrane. This membrane acts as a valve that rapidly closes and opens during phonation. This model can be used as a basis to address comparative morphological and physiological questions. More recently, the syrinx was modelled as a simple modified oscillator. Many features of the sound were captured remarkably well. The parameter values, however, did not represent the distribution of the actual material properties of the syrinx. These models demonstrated the minimum number of parameters required to describe the essential dynamics of the sound signal. Furthermore, we address possible interesting future directions for modelling.
