【摘要】：目的探讨6-24月龄正常生长发育的婴幼儿视觉强化测听(Visual reinforcement audiometry,VRA)具体测试方法及技巧；获得6-24月龄正常婴幼儿视觉强化测听的最小反应阈值(Minimal response level, MRL),为国内婴幼儿行为测听工作提供有价值的参考数据,推进视觉强化测听的开展。 方法2010年9月—2010年12月在我院地段保健处体检婴幼儿(6-24月龄),予以告知本课题内容及意义后,家长自愿带小儿来我科门诊听力室进行该测试者共96例,其中6-12月龄儿48例,12-24月龄儿48例。测试前询问基本情况,行电耳镜检查、耳声发射检查及声导抗检查,排除听力损伤病史。在标准隔音室中进行VRA：20例受试儿通过扬声器给声,76例受试儿佩戴插入式耳机给声,刺激声为啭音,视觉强化物为计算机动画视频,获取四个不同频率(500Hz、1000 Hz、2000 Hz、4000 Hz)的MRLs,记录测试时间。对于不能一次获得全部MRLs的受试者,进行第二次测试,必要时进行第三次测试。测试后,计算各组4个频率的平均MRLs,并进行统计学分析,分析MRLs与年龄、性别等之间的关系。 结果扬声器给声组：6-24月龄婴幼儿500Hz,1000Hz、2000Hz、4000Hz的平均MRLs依次为：31.23 dB、32 dB、30.75 dB、30.88 dB;经单因素方差分析：受试者左右耳的平均MRLs间无统计学差异：不同性别受试者的平均MRLs间无统计学差异；6-12月龄与12-24月龄婴幼儿500Hz的平均MRLs分别为32.92 dB、28.44 dB,p0.05,差值具有统计学意义,其余3个频率的平均MRLs间无统计学差异。插入式耳机给声组：6-24月龄婴幼儿500Hz、1000Hz、2000Hz,4000Hz的MRLs依次为：10.23 dB,9.65 dB,8.80 dB,8.12 dB；6-12月龄婴儿500Hz,, 1000Hz,2000Hz,4000Hz的平均MRLs依次为：13.50 dB、12.85 dB 11.15 dB、10.26,12-24月龄幼儿500Hz、1000Hz、2000Hz、4000Hz的平均MRLs依次为：6.95 dB、6.45 dB、6.45 dB、6.01 dB;经单因素方差分析：不同性别受试者各频率的平均MRLs无统计学差异；6-12月龄及12-24月龄4个频率平均MRLs,方差分析结果均p0.05,差值具有统计学意义。 结论使用扬声器给啭音、计算机动画进行强化的VRA的平均MRLs明显大于插入式耳机给声的VRA获得的结果；使用插入式耳机给啭音、计算机动画进行强化的VRA各频率的平均MRLs与年龄均有较明显关系,阂值随着年龄增加而变小；进行行为测听时,性别对最小反应阈值的影响不明显。因此,不同测听室在制定行为测听参考值时应考虑年龄对参考值的影响。
[Abstract]:Objective to explore the specific test methods and techniques of visual intensive audiometry (Visual reinforcement audiometry,VRA) in infants with normal growth and development of 6-24 months. The minimum response threshold (Minimal response level, MRL),) of visual intensive audiometry for normal infants aged 6-24 months was obtained to provide valuable reference data for behavioral audiometry of infants and young children in China and to promote the development of visual intensive audiometry. Methods from September 2010 to December 2010, infants and infants (6-24 months old) were examined in our local health care department. After informing the content and significance of this subject, 96 children were voluntarily brought by parents to the hearing room of our outpatient department. There were 48 infants aged 6-12 months and 48 infants aged 12-24 months. The basic information was inquired before the test, and the history of hearing impairment was excluded by the examination of electric otoscope, otoacoustic emission and acoustic conductance. In the standard soundproof chamber, VRA:20 children were given sound via loudspeaker, 76 children wore plugged earphones to give the sound, the stimulus sound was trill sound, the visual intensifier was computer animated video, and four different frequencies (500Hz / 1000 Hz,2000 Hz,) were obtained. 4000 Hz) MRLs, records test time. For subjects who cannot obtain all MRLs at once, a second test and, if necessary, a third test. After the test, the average MRLs, of 4 frequencies in each group was calculated and statistically analyzed to analyze the relationship between MRLs and age, sex, etc. Results the average MRLs of the loudspeaker group was 31.23 dB,32 dB,30.75 dB,30.88 dB; for 500Hz ~ 1000Hz ~ 1000Hz ~ 2000Hz in infants aged 6-24 months. By univariate analysis of variance, there was no statistical difference between the mean MRLs of the left and right ears of the subjects, and there was no statistical difference between the mean MRLs of the subjects of different genders. The average MRLs of 6-12 month old and 12-24 month old infants was 32.92 dB,28.44 dB,p0.05, respectively. There was no significant difference between the other three frequency average MRLs. The MRLs of the insertion earphone feeding group: 500Hz / 1000Hz / 1000Hz / 100Hz / 100Hz / 100Hz / 24 months old is 10.23 dB,9.65 dB,8.80 dB,8.12 dB;, respectively. The average MRLs of 500Hz for 6-12 months old infants and 2000Hz for 1000Hzn is 13.50 dB,12.85 dB 11.15 dB,10.26,12-24 / month, and the average MRLs is 6.95 dB,6.45 dB, for 500Hz / 1000HzN 2000Hz / month infants. 6.01 dB; Univariate analysis of variance showed that there was no significant difference in average MRLs among different gender subjects. The results of MRLs, variance analysis of 4 frequencies at 6-12 and 12-24 months of age were all p0.05, the difference was statistically significant. Conclusion the average MRLs of VRA enhanced by computer animation is significantly higher than that of VRA given by plugged earphones. The average MRLs of each frequency of VRA enhanced by computer animation was significantly related to age, and the threshold value decreased with age, while gender had no significant effect on the minimum response threshold in behavioral audiometry. Therefore, the influence of age on the reference value should be taken into account in different hearing test rooms.
