声音可以通过声带的振动产生，声带的振动共同形成了一个高效的振荡器。持续的发声和对振动应力的自我保护取决于褶皱的组织结构和分子组成。它们的结缔组织，固有层，在人类和其他哺乳动物物种中具有多层结构。组织的层次性决定了其生物力学特征。喉肌可以改变声带的生物力学特性，从而允许发出各种各样的声音。本文描述了人类和动物声带的层状组织，并解释了它们的生物力学特性及其与振动功能的关系。
Voice can be produced by the vibration of the vocal folds that together form a highly efficient oscillator. Sustained phonation and self-protection against vibratory stresses depend on the histological organization and molecular composition of the folds. Their connective tissue, the lamina propria, has a multilayered structure in humans and other mammalian species. The layered organization determines its biomechanical features. Laryngeal muscles can modify the biomechanical characteristics of the vocal folds, thus permitting the emission of a wide variety of sounds. Laminar organization of human and animal vocal folds is described and their biomechanical properties and relationship with the oscillatory function is explained.
