The new acoustic measurement services will be developed in phases 新的声学校正服务将分作以下两个阶段设立。
Specification for manikin for simulated in situ airborne acoustic measurements 模拟现场空气中声测量用的人体模型规范
Underwater acoustic measurement 水声测量
Provisional head and torso simulator for acoustic measurements on air conduction hearing aids 空气传导助听器声学测量用临时头戴筒式模拟器
Scl is in the process of setting up measurement standards and calibration facilities for acoustic measurements 标准及校正实验所正著手建立声学计量标准及校正设备
