Φ２４ｍｍ测试电容传声器声压灵敏度的校准张明锋，陈玲（陕西师范大学声学所，７１００６２）一、引言目前，我国及国际上的声压标准都是在２３．７７ｍｍ实验室标准传声路基础上建立的。为了向国家标准靠拢及进行国际间的比对，近年来我国生产的测试电容传声器（下称传... Calibration of Acoustical Pressure Sensitivity of Φ24mm Test Capacitor Microphone Zhang Mingfeng, Chen Ling (Institute of Acoustics, Shaanxi Normal University, Xi’an 710062) I. INTRODUCTION At present, the sound pressure standards in our country and in the world are all established on the basis of 23.77mm standard laboratory soundtracks of. In order to move closer to national standards and international comparison, in recent years China’s production of test capacitance microphone (...
