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: 11 subjects abilities to detect near threshold pure tone levels were measured in different noise free from hearing disorder.
方法：测试在不同的噪声水平时听力正常的11名受试者感知听阈附近纯音的能力。
Objective To investigate the difference and relationship between auditory steady-state evoked response(ASSR threshold), auditory brain stem response(ABR threshold) and pure tone threshold.
目的研究听觉稳态诱发反应（ASSR）和听性脑干反应（ABR）阈与纯音听阈的差别和相关性。
The results indicated that DPOAE gram was accurate in reflecting the range of frequencies of injured ears; the amplitude and incidence of DPOAE were associated with pure-tone behavioral threshold.
结果表明：DPOAE可以准确地反映患耳相应的频率损失范围，其检出率和幅值与主观听阈水平有关。
