masking tone

常見例句

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例受試者（60耳）分別進(jìn)行純音測聽，首先測出雙耳的純音聽閾，然后應(yīng)用同頻音掩蔽試驗測試各個頻率的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.
目的應(yīng)用同頻音掩蔽試驗觀察不同個體最小對側(cè)掩蔽級（MCML）與主觀純音聽閾之間的關(guān)系，進(jìn)而通過MCML判定被試者主觀真實聽閾。
