摘要
目的通过比较听力障碍患者在单一听觉模式和视听结合模式下的噪声下语句识别率,分析唇读信息对耳聋患者噪声下语句感知能力的影响。方法选择中度感音神经性听力损失患者14名,年龄55.4±9.1岁,均为语后聋。分别在单一听觉模式和视听结合两种模式下,应用中文普通话版嘈杂语噪声下语句识别表对患者进行噪声下语句识别率测试(言语强度30dB SL,信噪比5dB)。结果 14例患者在单一听觉模式下语句识别率为73.79%±7.95%,在视听结合模式下语句识别率为86.57%±5.42%,后者高于前者,差异有统计学意义(P<0.05)。结论在噪声环境下,唇读信息对听力损失患者的语句识别有明显的提高作用。
Objective This experiment was to analyze the impacts of lip-reading information on hearing im- paired subjects＇ sentence recognition got in noisy environment in comparing with the results obtained from the listen- ing and audio-visual testing ways. Methods Fourteen moderate hearing impaired subjects with 55.4±9.1 years old were postlingual deafness. Their sentence recognition ability were tested in noisy environments with speech and audio -visual information separately （speech intensity： 30 dB SL, SNR：5 dB）. Results Compared with the sentence recognition administered in the speech information condition 73.79%±7.95%, the subjects sentence recognition un- der the audio-visual condition was 86.57%±5.42%, which was significantly different （P〈0.05）. Conclusion In noisy environment, lip-reading can improve hearing impaired patients＇ sentence recognition obviously.
