纯音听阈测定是受检耳对不同频率的纯音恰能听到的最轻声音，是判断听敏度的标准，按GB7583-87规定某人的听阈是在规定条件下，以一规定的声信号，在多次重复试验中，有一半以上的次数能正确引起听觉的最小声压级。
结论TEOAE对中耳病变的诊断较纯音听阈测试、声导抗测试敏感。
Conclusion TEOAE is more sensitive than audiogram and acoustic immittance in the diagnosis of middle ear disorders.
方法对120例耳源性眩晕患者进行纯音听阈测试，甘油试验，耳蜗电图，冷热水试验，前庭诱发肌源性电位检查。
Methods We conducted the pure tone audiology, glycerol test, electrocochleogram(ECochG) , water caloric test, vestibular evoked myogenic potentils(VEMP) in 120 aural vertigo patients.
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。
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.
