摘　　要：目的探讨不同月龄婴儿不同频率探测音声反射(acoustic reflex,AR)的引出率及反射阈,以指导选择合适的探测音对婴儿行声反射测试。方法选取符合纳入条件的3月龄婴儿73例,分别进行226 Hz及1 000Hz探测音的同侧AR测试,其中28例6月龄时再次行226Hz及1 000Hz的同侧AR测试,比较3、6月龄婴儿的AR引出率及反射阈。结果本组婴儿3月龄及6月龄时,1 000 Hz探测音的AR引出率均高于226 Hz(P<0.05),1 000Hz探测音的声反射阈(acoustic stapedial reflex threshold,ASRT)均低于226Hz;与3月龄时相比,6月龄时1 000Hz探测音测得的ASRT升高,而226Hz探测音的ASRT稍降低(P<0.05)。结论对于3月龄及6月龄的婴儿,宜选用1 000Hz探测音行AR测试,临床上需针对不同月龄婴儿制定不同的ASRT参考范围。Objective To investigate the acoustic reflex（AR）with different frequencies of probe tones in infants of different ages.This could set up guidelines for the choice of probe tones when testing AR.Methods A total of 73 infants at 3 months were recruited for this study.Ipsilateral AR measurements with 226 Hz and 1 000 Hz probe tones were obtained separately.At 6 months,28 infants received the tests again.Results The percentage of the presence of AR with 1 000 Hz probe tone was higher than that with 226 Hz probe in both the 3 and 6 months（P〈0.05）,and the acoustic stapedial reflex thresholds（ASRT）with 1 000 Hz probe tone were lower than that with226 Hz probe.When compared with the ASRT at 3 months,the ASRT at 6 months was higher when tested with1 000 Hz probe tone,while lower when measured with 226 Hz probe tone（P〈0.05）.Conclusion For infants at 3 and 6 months,the AR test with 1 000 Hz probe tone showed more advantages over 226 Hz probe.It was necessary to have separate sets of normative data of ASRT with varied age periods of infants.
