                摘要：语言可懂度是衡量通信系统质量的关键指标，强噪声环境下难以直接通过主观测试方法测试语言
                可懂度。该文提出了一种强噪声环境下主观语言可懂度间接测试方法，设计了 3 种听音信号生成模式，在
                90 ∼ 110 dB 粉红噪声环境中完成了耳机式通信系统汉语数码报文的语言可懂度测试实验，分析了强噪声环
                境下噪声声压级、信噪比等因素对数码报文、数字的语言可懂度间接测试结果的影响规律，进而研究了强噪声
                环境下语言可懂度直接、间接测试结果的相关性。结果显示，在强噪声环境下无法直接进行语言可懂度主观测
                试时，间接测试可作为一种补充方案使用。

                 Abstract: Speech intelligibility is a key index for evaluating the quality of communication system. However it
                 is difficult to test the speech intelligibility directly by subjective test method in high-power noise environment.
                 This paper proposes an indirect test method for testing the subjective speech intelligibility in high-power noise
                 environments, designs three listening signal generation modes. This study conducts the speech intelligibility
                 tests on Chinese digital messages of headset type communication system in 90–110 dB pink noise, analyzing the
                 influence of noise sound pressure level, signal-to-noise ratio and other factors on the indirect test outcomes for
                 the speech intelligibility of digital messages and figures in high power noise conditions. The correlation between
                 the direct and indirect speech intelligibility test results in a high power noise environment is also investigated.
                 The results show that the indirect test can be used as a supplementary program when conducting a direct
                 subjective speech intelligibility test is unfeasible in high-power noise environments.
