摘要/Abstract

摘要： 目的探讨听力正常青年人宽频声导抗(WAI)能量吸收率(EA)的特点,并比较EA在耳别、性别之间的差异。方法选择听力正常青年人60例(120耳),分别行纯音测听、声导抗、宽频声导抗检查,分析检查结果,进行统计学分析。结果 EA值呈不规则的倒“W”型。左右耳的能量吸收率仅在2 000 Hz频率段有统计学意义,余频率段无统计学意义。在250 Hz~630 Hz之间的女性能量吸收率稍低于男性的能量吸收率,在630 Hz~3 150 Hz之间女性的能量吸收率稍高于男性的能量吸收率,其差异无统计学意义。结论正常青年人宽频声导在低频时能量吸收率较低,后迅速增长;中高频能量吸收率值较高。宽频声导抗能量吸收率在耳别、性别之间无明显差异。在临床应用中通过比较宽频声导抗能量吸收率的差异性,可增加中耳疾病诊断的特异度和灵敏度。

Abstract: Objective To explore characteristics of energy absorbance(EA)of wideband acoustic immittance(WAI)in young adults with normal hearing, and to compare the inter-ear and inter-sex differences in EA. Methods Sixty normal hearing young adults(120 ears)were selected and subjected to pure tone audiometry, acoustic impedance, and wideband acoustic immittance tests. The results were statistically analyzed. Results EA demonstrated an irregularly inverted “W” type of trend. Differences in EA were statistically significant at the frequency of 2 000 Hz, while there were no significant differences with regard to the residual frequency. The EA between 250 Hz and 630 Hz in women were slightly lower than that in men. The EA between 630 Hz and 3 150 Hz in women were slightly higher than that in men; however, the difference was not statistically significant. Conclusion The EA of young adults with normal hearing was particularly low at lower frequencies, and subsequently increase rapidly; furthermore, the EA for mid-high frequencies were relatively higher. WAI did not demonstrate significant differences between ears and both sexes. Comparing the differences in EA could be used to increase the specificity and sensitivity of the diagnosis of middle ear diseases in clinical settings.
