The characteristic values of broadband acoustic immittance of children of different ages during secretory otitis media were collected resonance frequency and absorption rate of middle ear in children of different ages were compared. Eighty-two children with secretory otitis media were selected for the broadband acoustic immittance test, including 62 cases （83 ears） in the young effusion group（[3.5±0.7]months）, and 20 cases （40 ears） in the older effusion group（[4.0±0.6]years old）. 82 normal children were selected for broadband acoustic immittance test in the same environment, including 62 cases （124 ears） in the younger normal group and 20 cases （40 ears） in the older normal group. The resonance frequency and absorptivity of different age groups under broadband peak pressure were compared, and the frequency absorptivity curve was drawn for analysis. The resonance frequencies of older normal group and younger normal group, older effusion group and older normal group, younger effusion group and younger normal group, older effusion group and younger effusion group were statistically significant（<0.001）. Analysis of sound energy absorption rate at different ages. There was significant difference in sound energy absorption rate between older normal group and younger normal group at 226-1155 / 4757-8000 Hz（<0.001）. The difference of full frequency sound energy absorption rate between the older effusion group and the older normal group was statistically significant（<0.001）, among which the difference of 866-1542 / 2520-4362 Hz absorption rate was the largest. The difference of full frequency sound energy absorption rate between young effusion group and young normal group was statistically significant（<0.001）, and the difference of 1091-2245 / 3776-5494 Hz absorption rate was the largest. Middle ear effusion in children of different ages has different performance under broadband acoustic immittance peak pressure, and has its own characteristic acoustic energy absorption frequency band. This study provides a reference basis for the analysis of the characteristics of middle ear sound transmission in children with secretory otitis media in the future.
收集不同年龄段分泌性中耳炎患儿的宽带声导抗特征值，比较不同年龄段儿童中耳的共振频率和吸收率。选取82例分泌性中耳炎患儿进行宽带声导抗测试，其中幼儿积液组（[3.5±0.7]个月）62例（83耳），年长积液组（[4.0±0.6]岁）20例（40耳）。选取82例正常儿童在相同环境下进行宽带声导抗测试，其中幼儿正常组62例（124耳），年长正常组20例（40耳）。比较不同年龄组在宽带峰值压力下的共振频率和吸收率，并绘制频率吸收率曲线进行分析。年长正常组与幼儿正常组、年长积液组与年长正常组、幼儿积液组与幼儿正常组、年长积液组与幼儿积液组的共振频率差异有统计学意义（<0.001）。分析不同年龄段的声能吸收率。年长正常组与幼儿正常组在226 - 1155 / 4757 - 8000Hz声能吸收率差异有统计学意义（<0.001）。年长积液组与年长正常组全频声能吸收率差异有统计学意义（<0.001），其中866 - 1542 / 2520 - 4362Hz吸收率差异最大。幼儿积液组与幼儿正常组全频声能吸收率差异有统计学意义（<0.001），1091 - 2245 / 3776 - 5494Hz吸收率差异最大。不同年龄段儿童中耳积液在宽带声导抗下表现不同，有其自身特征性的声能吸收频段。本研究为今后分析分泌性中耳炎患儿中耳声音传导特性提供参考依据。
