中文摘要：

激光多普勒测振仪在耳科学研究中用于对鼓膜、听骨链、鼓岬、基底膜等振动特性进行非接触式的精准测量,其结果能够反映各部分的动力学特性及声音信号在外周听觉系统中的传播特征。在研究不同病理状态对听觉系统的影响机制、听觉重建术以及术中进行听力康复预测等方面具有重要意义。

英文摘要：

Laser Doppler Vibrometer is used as a non-contact and precision measurement in otology research for detecting vibration of the tympanic membrane, ossicular chain, cochlear promontory and basilar membrane. The results reflect the dynamic characteristics of each part and help evaluate sound-transmitting properties through the peripheral auditory system. Therefore the use of LDV is of great significance to increasing understanding of the influence of different pathologies on the auditory system, and to proper design and optimization of auditory reconstructive surgeries and listening assistance devices. It also has the potential of becoming an objective technique for intraoperative monitoring.
