本文件规定了靠近耳朵的声源发出声音的基本框架测量方法。这些测量是用一个人体模型进行的，该模型配有包括麦克风在内的耳朵模拟器。随后将测量值转换为相应的自由场或漫射场水平。结果以自由场相关或扩散场相关的等效连续A加权声压级给出。这种技术被称为人体模型技术。 本文件适用于接触耳朵附近来源的声音，例如在设备测试期间或在工作场所接触耳机或带有音频通信设施的听力保护器发出的声音。 本文件适用于20 Hz至10 kHz的频率范围。对于10 kHz以上的频率，可以使用ISO 11904-1。

This document specifies basic framework measurement methods for sound immission from sound sources placed close to the ear. These measurements are carried out with a manikin, equipped with ear simulators including microphones. The measured values are subsequently converted into corresponding free-field or diffuse-field levels. The results are given as free-field related or diffuse-field related equivalent continuous A-weighted sound pressure levels. The technique is denoted the manikin technique. This document is applicable to exposure to sound from sources close to the ear, for example during equipment tests or at the workplace to sound from earphones or hearing protectors with audio communication facilities. This document is applicable in the frequency range from 20 Hz to 10 kHz. For frequencies above 10 kHz, ISO 11904-1 can be used.
