【摘要】：目的采用chirp信号作为声刺激进行听性稳态反应(auditory steady-state response,ASSR)测试,观察chirp-ASSR反应阈值与纯音听阈阈值的相关性,探讨chirp-ASSR客观听力检测在儿童临床听力评估中的价值。方法选取2012年6月至2013年2月中山大学附属第六医院听力中心检测的儿童共40例(共74耳)作为研究对象,在0.5kHz、1.0kHz、2.0kHz和4.0kHz处进行chirp-ASSR和纯音听阈测试,并对结果进行统计学分析。结果 40例接受测试的儿童年龄4-13岁,平均年龄7.7岁。纳入研究的74耳包括男48耳,女26耳;右34耳,左40耳;正常听力59耳,听力损失轻度4耳、中度6耳、重度5耳。0.5-4kHz频率chirp-ASSR反应阈与纯音听阈的相关系数r分别为0.812、0.884、0.842、0.892;chirp-ASSR反应阈经过校正后所得的各频率预估听阈与纯音听阈值更加接近。结论 chirp-ASSR作为一种具有频率特异性的客观测听技术,能够较好的反映儿童真实的听力水平。
[Abstract]:Objective to observe the correlation between chirp threshold and pure tone threshold for auditory steady state response (auditory steady-state response,ASSR) by using chirp-ASSR signal as acoustic stimulation. To explore the value of chirp-ASSR objective audiometry in children's clinical hearing assessment. Methods from June 2012 to February 2013, 40 children (74 ears) in the hearing Center of the sixth affiliated Hospital of Sun Yat-sen University were selected as subjects. Chirp-ASSR and pure tone audiometry were performed at 0.5 kHz, 1.0 kHz, 2.0 kHz and 4.0kHz. The results were analyzed statistically. Results 40 children were 4 years old and 13 years old, with an average age of 7.7 years. The 74 ears included 48 males and 26 females, 34 right ears and 40 left ears. There were 59 ears with normal hearing, 4 ears with mild hearing loss, 6 ears with moderate hearing loss and 5 ears with severe hearing loss. The correlation coefficients between chirp-ASSR threshold and pure tone hearing threshold at 0.5-4kHz frequency were 0.812,0.884, 0.842 and 0.892, respectively. The predicted hearing threshold of each frequency obtained from the chirp-ASSR response threshold after correction is more close to the pure tone threshold. Conclusion as a frequency-specific objective audiometry, chirp-ASSR can reflect the true listening level of children.
