Extended high-frequency (EHF) hearing was studied in children with and without histories of chronic or recurrent otitis media (OM). The EHF thresholds were found to have good test-retest repeatability. Children with OM histories had poorer EHF hearing than children without OM histories. The EHF hearing in OM children appeared to be related to OM severity. Children with residual tympanometric abnormalities had poorer EHF hearing than OM children with normal middle ear function. The results suggest evidence for middle ear and inner ear components of EHF hearing losses in children with OM.
对有和没有慢性或复发性中耳炎（OM）病史的儿童进行了扩展高频（EHF）听力研究。发现EHF阈值具有良好的重测重复性。有OM病史的儿童的EHF听力比没有OM病史的儿童差。OM儿童的EHF听力似乎与OM严重程度有关。残留鼓室图异常的儿童比中耳功能正常的OM儿童的EHF听力差。结果表明，有OM的儿童EHF听力损失存在中耳和内耳因素的证据。
