| 摘 要： | 针对声带振动在喉内所产生的声场难以分析的问题,该文根据声带的发声机制,提出了模拟声带振动的一种新模型,并对模型中对角线上的声压变化规律及微小振元的数目对声带振动所产生的近声场的影响进行了研究.运用Matlab对取得的变化规律进行仿真,结果表明,在新模型中,微元法可实现对近声场的理论研究；从而为进一步研究声带振动及其产生...

| Abstract: | For the sound field generated by the vocal fold vibration in the laryngeal is difficult to analyze.This article presents a new model of simulating voice vibration,based on the mechanism of vocal cord voice.The sound pressure change in the the diagonal line of the model and the impact of the change of the number of vocal cord vibration element on the sound field have been investigated.A simulation of sound pressure changes has been carried out by using Matlab.The results shows that,in the new model,the use o... |
