In a sample of 104 elderly nursing home residents, collapsed ear canals were found in 41% of the subjects. Age emerged as a significant factor in these data since collapsed ear canals were significantly more common among the nursing home residents that were age 80 or over. Based on these findings, mean hearing threshold data on this population will overestimate hearing loss by 2-8 dB when collapsing ear canals are not considered.
在104名老年疗养院居民的样本中，41%的受试者存在耳道塌陷。年龄在这些数据中成为一个显著因素，因为耳道塌陷在80岁及以上的疗养院居民中明显更为常见。基于这些发现，当不考虑耳道塌陷时，该人群的平均听力阈值数据将高估听力损失2至8分贝。
