Objective to investigate the relationship between minimum contralateral masking level (MCML) and pure tone threshold of the masking ears by the same frequency tone masking test.
目的应用同频音掩蔽试验观察不同个体最小对侧掩蔽级(MCML)与主观纯音听阈之间的关系，进而通过MCML判定被试者主观真实听阈。
Methods the pure tone thresholds of 30 subjects (60 ears) were measured by pure tone audiometry and MCML was obtained by means of the same frequency tone masking test.
方法30例受试者(60耳)分别进行纯音测听，首先测出双耳的纯音听阈，然后应用同频音掩蔽试验测试各个频率的MCML。
