Hearing levels are reported for a cohort of 222 infants (aged 7 to 24 months) and 540 older children (aged 2 to 12 years) with otitis media with effusion (OME). The infants had an average speech awareness threshold of 24.6 dB hearing level (HL). The older group had mean bone conduction thresholds less than 10 dB HL, and air conduction thresholds averaged 27 dB HL; however, acuity was 7 dB less impaired at 2,000 Hz. The mean three-frequency pure tone average and speech reception threshold were 24.5 and 22.7 dB, respectively. Hearing acuity was not significantly related to age or previous duration of OME. The otoscopic observation of an air-fluid level or bubbles was associated with less hearing impairment; however, a predictive relationship between hearing levels and tympanogram characteristics could not be demonstrated.
报告了222名患有中耳积液（OME）的婴儿（7至24个月大）和540名大龄儿童（2至12岁）的听力水平。这些婴儿的平均言语察觉阈为听力级（HL）24.6分贝。大龄儿童组的平均骨导阈值低于10分贝HL，气导阈值平均为27分贝HL；然而，在2000赫兹时听力敏锐度受损程度要低7分贝。平均三频率纯音平均值和言语接受阈分别为24.5分贝和22.7分贝。听力敏锐度与年龄或既往OME持续时间无显著相关性。耳镜观察到气液平面或气泡与听力损害较轻有关；然而，无法证明听力水平与鼓室图特征之间存在预测关系。
