Resonance frequency of the middle ear was examined in 24 persons with normal hearing, 10 patients with otosclerosis and 4 patients subjected to stapedioplasty. It is shown that shift of the resonance frequency is important for differential diagnosis. In particular, in otosclerosis resonance frequency shifts to higher values, while in mass increases (rupture of acoustic bones chain) there is a shift to lower frequencies.
对24名听力正常者、10名耳硬化症患者和4名接受镫骨手术者的中耳共振频率进行了检测。结果表明，共振频率的变化对鉴别诊断具有重要意义。特别是，在耳硬化症中，共振频率向更高值偏移，而在质量增加（听骨链中断）时，则向更低频率偏移。
