中文摘要：
目的：探讨普通话可接受噪声级（M—ANL）测试与患者导向的听觉改善分级（COSI）问卷在老年助听器验配效果评估中的应用。方法：招募首次选配助听器的老年听障者（〉60岁）32例，较好耳听损程度为中度到重度感音神经性聋，验配前进行M-ANL测试，验配6周后随访，填写COSI问卷。根据助听器佩戴时间将32位受试者分为3组：每天佩戴〈1h组（11例），每天佩戴1～〈4h组（13例），每天佩戴≥4h组（8例），比较3组受试者M-ANI。值与COSI得分的相关性。结果：①3组受试者之间M—ANI。值有显著差异（P〈0．05）；②〈1h组COSI得分明显低于1～〈4h组（P〈O．05），而1～〈4h组得分与≥4h组差异无统计学意义；③M—ANL值与COSI得分有较好相关性。结论：M—ANI。可较好预估助听器验配的满意度，而COSI问卷也在助听器效果评估中发挥有效作用。
英文摘要：
Objective： The purpose of this study was to inquiry into the application of mandarin acceptable noise level（M-ANL） and client oriented scale of improvement in evaluation of hearing aid fitting for presbyacusis. Method：Thirty-two adults with presbycusis who used the hearing aid for the first time were selected for the study. M-ANL tests were done prior to the hearing aid fitting. Six weeks later, these patients were asked to fill in ques- tionnaire of client oriented scale of improvement （COSI）. The subjects were divided into 3 groups according to the time of hearing aid using in their daily lives： less than one hour per day, 1 to 4 hours per day and more than 4 hours per day. The relativity of M-ANL and the score of COSI were compared. Result： （1）There were significant differences of the M-ANL among 3 groups（P（0.05） （Z）The scores of COSI of group 1（less than one hour per day） was lower than group 2（1 to 4 hours per day）, while there were no significant differences between the scores of group 2（1 to 4 hours per day） and group 3（more than 4 hours per day） ; （3） There was good correlation between the score of M-ANL and COSI. Conclusion： M-ANL can forecast the satisfaction of hearing aids fitting. And COSI can play an effective role in outcome measurement.
