Individual acoustic parameters of reverberation have the potential to affect both the intelligibility of speech and the degree of perceived reverberation. The current experiments used monaural acoustic simulations to investigate the effect of reverberation time (RT) and direct-to-reverberant ratio (DRR) on word and sentence intelligibility at different levels of analysis (phonemes, words, and sentences). Perceived reverberation and recall of sentences were also assessed. Intelligibility and perceived reverberation decreased with increasing RT and decreasing DRR (particularly between 0 and -10 dB). Results indicate consistent effects of both RT and DRR on the intelligibility and perceived reverberation of words and sentences.
混响的各个声学参数有可能影响语音清晰度和混响感的程度。当前的实验使用单声道声学模拟来研究混响时间（RT）和直达声与混响声比例（DRR）在不同分析层面（音素、单词和句子）上对单词和句子清晰度的影响。同时还评估了句子的混响感和回忆情况。随着RT增加和DRR降低（尤其是在0至 -10 dB之间），清晰度和混响感下降。结果表明，RT和DRR对单词和句子的清晰度及混响感均有一致的影响。
