摘　　要：实现了一种对非测试耳实施自适应掩蔽的骨导听阈自动测听方案,并开发了一套完整的基于个人终端的自动纯音测听程序。对20名正常听力受试者进行了自动测听,并与AC40临床听力计测听的结果对照。所估计的大多数气导听阈(96%)和骨导听阈(90%)与临床听力计测听结果差异在10 dB之内;且二者所测气、骨导听阈和气骨导(听阈)差的Bland-Altman图中数据基本位于95%置信区间范围内。与临床听力计测听的骨导听阈差的平均差均值和平均绝对差均值分别为-0.17 dB和4.52 dB,普遍小于已有的自动测听系统与临床听力计间的差异。A bone conduction automatic audiometry scheme with adaptive masking for the non-test ear was implemented,and a complete automated pure tone audiometry program based on personal terminals was developed.Automated pure tone audiometry was conducted on 20 normal hearing subjects,and the results were compared with those obtained using the AC40 clinical audiometer.The majority of estimated air conduction thresholds(96%)and bone conduction thresholds(90%)differed from the clinical audiometer results by less than 10 dB.Furthermore,in the Bland-Altman plots of air and bone conduction thresholds and the air-bone gap,the data largely fell within the 95%confidence interval.The average difference and mean absolute difference in bone conduction thresholds between the automated system and the clinical audiometer were-0.17 dB and 4.52 dB,respectively,both generally smaller than the differences reported in existing automated audiometry systems.
