汉语为母语者在安静和嘈杂噪声下的听觉能力研究

摘要

This study evaluated the performance of Mandarin Chinese speaking and English speaking individuals listening to Mandarin Chinese and English speech in corresponding babble noise. The results for the Mandarin Chinese listeners revealed a benefit when producing Lombard speech with the SNR50 for Mandarin Chinese significantly different between conversational and Lombard speech. In noisy situations where increasing vocal intensity is expected, Mandarin Chinese listeners appear to benefit from features preserved or enhanced through Lombard speech that English listeners do not access.%该研究对于讲中文和讲英文的人分别在中文和英文嘈杂声中的沟通能力做了比较和分析。结果显示讲中文的人能从嘈杂环境引起的大声用力讲话模式（Lombard speech）中获益，得到比在安静环境下交流明显不同的信噪比。在嘈杂的环境中人们为沟通都会提高音量，以汉语普通话为母语者似乎通过大声讲话而使一些言语特征在噪声中得以保留，从而有利于交流。这一特征在英语条件下并不明显。
