本文所描述的工作是有关改善摩擦模型，调查其生产中涉及的声学机制更密切。以往的研究综述分为四类：一般的航空声学，语音的机械模型，语音分析，理论模型，包括合成。这里报告的工作结合了这些不同的方法。三个层次的实验与机械模型越来越现实。结果，识别出两个源机制：障碍物源，其中声音在气流的突然障碍物处产生，例如在收缩部下游的齿状物处产生，对应于/s，x/;以及壁源，其中声音通过以与流成斜角的方式撞击壁而产生，对应于/c，x/。源光谱不同，并在每种情况下给出。比较语音数据模型的推导支持和扩展的结论。
The work described in this paper is concerned with improving fricative models by investigating the acoustic mechanisms involved in their production more closely. Previous studies reviewed fall into four categories: general aeroacoustics, mechanical models of speech, analysis of speech, and theoretical models, including synthesis. The work reported here combines these various approaches. Three levels of experiments with mechanical models of increasing realism are described. As a result, two source mechanisms are identified: the obstacle source, in which sound is generated at an abrupt obstacle to the airflow, such as the teeth, downstream of the constriction, corresponding to /s, ∫/; and the wall source, in which sound is generated by striking a wall at an oblique angle to the flow, corresponding to /c, x/. Source spectra differ, and are given in each case. Comparison to speech data from which the models were derived supports and extends the conclusions.
