采用室内声场仿真软件ODEON获取房间脉冲响应,然后将脉冲响应和消声室录制的语言清晰度测试信号卷积后通过耳机重放,进行汉语语言清晰度主观评价实验,建立和验证了主观汉语语言清晰度得分与客观声学参数C_(50)之间的关系.结果表明:在双耳有差别听闻条件下C_(50)(500～4000Hz)与主观汉语语言清晰度得分之间具有高相关性,采用C_(50)(500～4000Hz)能较好地预测厅堂的主观汉语语言清晰度得分. The indoor impulse simulation software ODEON was used to obtain the impulse response of the room. Then, the impulse response and the speech intelligibility test signal recorded in the anechoic chamber were convoluted and then replayed through the headphone. The subjective evaluation experiment of Chinese speech intelligibility was carried out, and the subjective Chinese language The relationship between sharpness score and objective acoustics parameter C_ (50) .The results show that there is a high correlation between C_ (50) (500 ~ 4000Hz) and subjective Chinese speech intelligibility score under different hearing conditions, The C_ (50) (500 ~ 4000Hz) can better predict the subjective Chinese language definition score of the halls.
