masking tone

常見(jiàn)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(cè)聽(tīng)，首先測(cè)出雙耳的純音聽(tīng)閾，然後應(yīng)用同頻音掩蔽試騐測(cè)試各個(gè)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)用同頻音掩蔽試騐觀察不同個(gè)躰最小對(duì)側(cè)掩蔽級(jí)（MCML）與主觀純音聽(tīng)閾之間的關(guān)系，進(jìn)而通過(guò)MCML判定被試者主觀真實(shí)聽(tīng)閾。
