摘　　要：目的通过比较窄带CE-Chirp ASSR、调频/调幅信号ASSR测试反应阈与极重度感音神经性聋儿行为测听阈的差值,从而探究窄带CE-Chirp ASSR和调频/调幅信号ASSR反应阈与行为听阈之间是否存在相关性以及各个频率之间的差异,从而来讨论两种不同刺激声诱发的ASSR在听阈评估方面的可靠性。方法对26名(40耳)极重度感音神经性听力损失患儿分别进行窄带CE-Chirp ASSR测试、调频/调幅信号ASSR测试和行为测听,评价窄带CE-Chirp ASSR反应阈、调频/调幅信号ASSR反应阈与行为听阈的相关性。结果窄带CE-Chirp反应阈与行为听阈之间有较高的相关性,但调频/调幅信号ASSR反应阈在0.5k、1k时与行为听阈不存在相关性,但在2k、4k Hz时的相关性较好。结论相对调频/调幅信号ASSR来说,窄带CE Chirp ASSR反应阈与行为测听阈的相关性较好。Objective To compare narrowband CE-Chirp ASSRs and AM/FM ASSRs and their correlation to be-havioral audiometry in children with severe sensorineural hearing Loss at different frequencies, in order to study the ac-curacy of the two types of evoked ASSRs in estimating hearing thresholds. Methods Children （n=26, 40 ears） with sen-sorineural hearing loss were tested using NB CE-Chirp ASSRs, FM/AM ASSRs and behavior audiometry, and thresh-olds at 0.5, 1, 2 and 4 kHz were compared across the tests. Results High levels of correlation were found between NB CE Chirp ASSR thresholds and behavioral audiometry thresholds, but not between AM/FM ASSRs and behavior audi-ometry for 0.5 and 1 kHz （although better for 2 and 4 kHz）. Conclusion Compared with AM/FM ASSRs, NB CE-Chirp ASSR thresholds are better correlated to those of behavioral audiometry.
