摘要
本文以96名大二学生为被试,考察其在安静条件下和在同一信噪比的白噪音、汉语两人嘈杂音、英语两人嘈杂音等背景下的英语对话理解表现,探讨不同类型嗓音对英语听力理解的影响。结果表明,中国学生在所有噪音中的听力理解表现均显著差于在安静条件下的表现;在白噪音中的表现好于在汉语和英语两人嘈杂音中的表现,而在后两者中的表现无显著差异。他们在安静条件下的听力表现与在噪音下的表现相关程度随噪音类型的不同而变化。此外,在安静条件下听力表现较好的学生,在各类噪音中受到的负面影响均显著大于表现较差的学生。
This paper presents a study on the effects of different types of noise on English listening comprehension among Chinese college students.A total of 96 sophomores listened to English conversations presented in quiet and in white noise,Chinese 2-talker babble,and English 2-talker babble at a fixed SNR respectively.The results showed that Chinese students'performance in listening comprehension tasks varied according to the types of noise.Specifically,they had significantly lower scores in all types of noise than their scores in quiet.They performed similarly in Chinese 2-talker babble and English 2-talker babble,and were significantly better in white noise.Furthermore,there was a significant correlation between their performance in quiet and that in noise,which varied with the types of noise.In addition,compared with students with lower scores in quiet,students with higher scores suffered a larger performance deficit due to the energetic and informational masking effects of noise.
