摘　　要：为了对受话器、耳机、听力计、电话机等与人耳听觉相关的电声器件和设备的声学指标进行客观测量和校准,国际电工委员会(IEC)制定了一系列耳模拟器(声耦合腔)的标准,耳模拟器(声耦合腔)和特定的测试传声器、前置放大器等组合成仿真耳(人工耳)。介绍这些仿真耳对应标准和相互之间的差异,以及它们的应用。The International Electrotechnical Commission （IEC） issues a series of standards of ear simulator （acoustic cou- pler） in order to make objective measurement of electroacoustic devices and equipments related the human ear hearing, for ex- ample ：receivers ,earphones, audiometers, telephones. The artificial ears are consisted of ear simulator （acoustic coupler）, special pressure microphone, microphone preamplifier etc. The difference of artificial ears and their corresponding standards, and their applications are introduced.
