Abstract

This presentation summarizes recent research concerning the maturation of sound transmission through the middle-ear conducting system of various vertebrate species. 2. In this review the structural and functional aspects of middle-ear development are presented, as well as the relationships between these events. 3. Functional changes in middle-ear transmission demonstrated that the efficiency of sound conduction improved dramatically during the period of development. 4. The functional development of the middle ear was then compared with the maturation of auditory sensitivity measured from more central locations in the auditory system. 5. The results indicated that conductive development in some species determined the rate of sensitivity development. 6. These findings add an important dimension to our understanding of the underlying processes of hearing maturation.

摘要

本报告总结了近期有关声音通过各种脊椎动物物种中耳传导系统成熟过程的研究。2. 在本综述中，介绍了中耳发育的结构和功能方面，以及这些事件之间的关系。3. 中耳传导的功能变化表明，在发育期间声音传导效率显著提高。4. 然后将中耳的功能发育与从听觉系统更中枢部位测量的听觉敏感性成熟情况进行了比较。5. 结果表明，某些物种的传导发育决定了敏感性发育的速度。6. 这些发现为我们对听力成熟潜在过程的理解增添了一个重要层面。
