中文摘要：

针对声带振动产生的声场的空间分布问题,该文根据声带的生理结构及振动特性,提出声带的振动模型,运用有限元法对声带振动产生的远声场的方向性进行理论研究,得到声场的方向性图,并得出一定的规律。其结果表明,无论是正常声带的振动还是病理性声带的振动,在声带振动模型中可实现声带的远场分析;从而为进一步研究声带振动及其产生的声场的分析做了基础。

英文摘要：

Aiming to the problem of sound field distribution of vocal cord vibration,this paper put forward the vibration model of vocal cords according to the vocal cords of physiological structure and vibration characteristics.Finite element method was used theoretically study the sound field orientation graph;and certain laws were obtained.The results showed that both normal and pathological vocal cord vibration,the the far-field analysis could be achieved in vocal cord vibration model.The study could provide a foundation for the further study
