| 摘 要： | 人体内包含有许多大小形态各异的软管系统,这些软管系统在大气流作用下,会产生各种各样的声信号。Fant,F1angann等人研究了语音信号产生的声学模型,阐明了来自于肺内的气流作用于声门、声道,产生语音信号的过程。Grotberg等人研究了肺中气道在气流作用下,哮喘音(wheezes)产生的声学模型,描述了哮喘音产生与气流流率之间的关系。这两类声信号主要源于管道与管内气流的相互作用。中国导引吐纳功在呼

| Abstract: | The mechanism for the nasal vibration to produce sound under the action of air current is reported; the critical condition for the production and the characteristic spectrum of such sound ard studied; and the characteristics of both the nasal vibration and air curreht are indicated. The investigation for the singularity of vibration sound of the living body has been made, and it has been found that the partial deformation of the living body due to the farce acting on it changes its characteristic vibration frequencies. |
