标准摘要
[中文适用范围]： 描述了一种耦合器，用于在使用通过耳塞（例如耳塞）耦合到耳朵的耳机来确定 200 Hz 至 5 000 Hz 频率范围内的气导助听器的物理性能特征时，为耳机加载指定的声阻抗。模具或类似设备。使用该耦合器无法获得助听器在人身上的实际性能。建议使用它作为交换助听器规格和物理数据的简单且现成的方法。 [外文原描述]： Describes a coupler for loading the earphone with a specified acoustic impedance when determining the physical performance characteristics, in the frequency range 200 Hz to 5 000 Hz, of air-conduction hearing aids using earphones coupled to the ear by means of ear inserts, e.g. ear moulds or similar devices. The use of this coupler does not allow the actual performance of a hearing aid on a person to be obtained. Its use is recommended as a simple and ready means for the exchange of specifications and of physical data on hearing aids.
英文名称IEC reference coupler for the measurement of hearing aids using earphones coupled to the ear by means of ear inserts
