In a sample of 80 persons in the 60-79-year age range, threshold shifts suggestive of collapsible ear canals were found in over one third of the subjects. A very conservative interpretation of the data suggests that at least 10-16% of these 60-79-year old elderly subjects have collapsible ear canals. Neither sex nor age was related significantly to prevalence. Results of this study indicate that in testing elderly persons there are threshold inaccuracies, relating possibly to collapsible ear canals, which, if not taken into account, may cause unacceptably large errors in both clinical and research applications.
在一个由80名年龄在60至79岁之间的人组成的样本中，超过三分之一的受试者出现了提示耳道可塌陷的阈值变化。对数据的一种非常保守的解释表明，在这些60至79岁的老年受试者中，至少有10%至16%的人耳道可塌陷。患病率与性别和年龄均无显著关联。这项研究的结果表明，在测试老年人时存在阈值不准确的情况，这可能与耳道可塌陷有关，如果不加以考虑，可能会在临床和研究应用中导致不可接受的大误差。
