摘要
文中根据消声室当前的校准现状,依据《JJF 1147-2006消声室和半消声室声学特性校准规范》的要求,对消声室的校准装置进行了研究和设计,研制了一套新的自动校准系统,并给出该装置的不确定度评定,提高了计量检测人员的工作效率和测试准确性,降低了人为因素对检测结果的影响。
This paper based on the current anechoic room calibration status, according to the requirement of JJF 1147-2006 'calibration specification on acoustic characteristic of Anechoic room and semi-anechoic room', makes a research and design on the calibration device of anechoic room. The paper has beendeveloped a new automatic calibration system, and provided the uncertainty evaluation of the system, to improve the efficiency of test personnel and test accuracy, and reduce the influence of human factors on test results.
