The objective of this investigation was to determine the effect of the aging process on various measures derived from multifrequency tympanograms.
Tympanograms were recorded at 226 Hz and at one-sixth octave intervals from 250 through 2000 Hz from 136 adult male subjects; 20 in each decade of life from age 20 through age 79 and 16 older than 79 yr of age. Analyses were performed on two measures of resonant frequency of the middle ear, two measures of static admittance at 226 Hz, and tympanometric width at 226 Hz.
No systematic effect of age on any of these measures was evident in this population except for a small, but significant, correlation between tympanometric width and age. Analyses of variance indicated no significant difference among mean values on any measure when subjects were grouped by decade of life. Values of these tympanometric variables are reported to add to the growing base of data from normal low-frequency and multifrequency tympanograms.
The main finding of this investigation indicates that normative values of middle ear resonance, admittance, and tympanometric width obtained from groups of adults of various ages can be applied to elderly men.
本研究的目的是确定衰老过程对从多频鼓室图得出的各项测量指标的影响。
对136名成年男性受试者在226赫兹以及从250赫兹到2000赫兹以六分之一倍频程间隔记录鼓室图；年龄从20岁到79岁，每十岁一组，每组20人，另有16人年龄超过79岁。对中耳共振频率的两项测量指标、226赫兹时的静态导纳的两项测量指标以及226赫兹时的鼓室图宽度进行了分析。
在该人群中，除鼓室图宽度与年龄之间存在小但显著的相关性外，未发现年龄对这些测量指标有任何系统性影响。方差分析表明，按年龄十年分组时，任何测量指标的平均值之间均无显著差异。据报道，这些鼓室图变量的值增加了来自正常低频和多频鼓室图的不断增长的数据基础。
本研究的主要发现表明，从不同年龄组的成年人中获得的中耳共振、导纳和鼓室图宽度的标准值可应用于老年男性。
