The relative occurrence of bell-shaped and various types of W-shaped susceptance-conductance and admittance-phase tympanograms at a probe-tone frequency of 660 Hz was determined from registrations on normal ears. The diagnostic value of the susceptance-conductance versus the admittance-phase representation of tympanograms was studied on pathological middle-ear systems. Using probe-tone frequencies from 510 Hz up to 910 Hz, tympanograms for all four imminent components were recorded on 10 pathological ears and the diagnostic value compared. From the combination of these studies we conclude that the admittance-phase approach at a probe tone frequency between 500 and 700 Hz is a good choice.
通过对正常耳朵的记录，确定了在660赫兹探测音频率下钟形以及各种类型的W形电纳-电导和导纳-相位鼓室图的相对发生率。在病理性中耳系统上研究了鼓室图的电纳-电导与导纳-相位表示法的诊断价值。使用从510赫兹到910赫兹的探测音频率，在10只病理性耳朵上记录了所有四个主要成分的鼓室图，并比较了诊断价值。从这些研究的结合中我们得出结论，在500至700赫兹之间的探测音频率下采用导纳-相位方法是一个不错的选择。
