摘要
母语为汉语听者在英语地区进行单耳电话通信时,常使用英语进行交流,此时背景噪声影响通信语言可懂度。研究了咖啡厅噪声环境下,英语语音通信可懂度受信号耳3种信噪比以及对侧耳不同噪声级的影响。实验结果表明:信号耳信噪比越高,平均可懂度越大;信号耳信噪比高时,对侧耳噪声变化对可懂度产生的影响不显著;信噪比低时,适当对侧耳噪声级可提高可懂度,可懂度在对侧耳噪声级为80到82 d B时为较高值。为提高咖啡厅噪声环境下单耳通信可懂度,应提高信号耳处信噪比,将对侧耳噪声级控制在80到82 d B间。
During the monaural phone communication for native Chinese speakers in English-speaking areas, English is often used and the ambient noise affects the speech intelligibility(SI) of the communication. This paper investigates the SI of English sentences under the cafeteria noise with different level of noise presented to the contralateral ear and 3 different signal to noise ratios(SNR) in the signal ear. The experimental results show that the SI is improved with the SNR in the signal ear increasing, a proper level of contralateral noise improves the SI and the SI is comparatively high when the contralateral noise is about 80 to 82 d B. To improve the SI of monaural phone communication under cafeteria noise, SNR should be made larger and the level of contralateral noise should be adjusted to about 80 to 82 d B.
