masking tone

常见例句

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。
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。
