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.

模拟室内声学参数对单音节单词和句子的清晰度和可感知混响的影响。

混响的各个声学参数可能会影响语音的清晰度和所感知的混响程度。当前的实验使用单声道声学模拟来研究混响时间（RT）和直接混响比（DRR）对不同分析级别（音素，单词和句子）的单词和句子清晰度的影响。还评估了感知的混响和句子的回忆。清晰度和可感觉到的混响随RT的增加和DRR的减少（特别是在0至-10 dB之间）而降低。结果表明，RT和DRR对单词和句子的清晰度和感知的混响均具有一致的影响。
