| 摘 要： | 针对强噪手术器械在相关手术过程中可能带来的噪声问题,本文探讨了利用主动噪声控制(ANC)技术进行噪声消除和控制的可能性和可行方案。通过简化的声学理论分析建立了一种基于直接声场干涉的ANC效果工程估计模型(EEM),通过该模型分析可以提供对设计方案的ANC效果的直观和定量分析;并且在模型分析基础上提出了一种针对操作者头部附近局部空间控制的ANC方案;最后通过一个实际声场测量实验验证了提出方案的有效性。

| Abstract: | Noise problem is encountered in many types of surgery,especially in orthopaedic surgery,where the cutting tool and its actuation part such as motor always generates big noise.This work is dedicated to developing a novel and promising solution based on the active noise control(ANC) technology to solve the noise problem in an orthopaedic theatre.The development process began with building an engineering evaluation model(EEM) to analyze the specifics of sound interactions and sound field involved in the noise ... |
