1·Methods: The groups of different age were examined by extended high frequency audiometry .
方法应用扩展高颇测听对不同年龄组人群进行听力检测。
2·Pure tone audiometry: Slight sensorineural hearing loss mainly at the lower frequency may be detected during or soon after attack. It may be recovered or lightened after the attack.
纯音测听：发作时或发作后不久，可检测到轻度的、以低频听力损失为主的感觉神经性耳聋，发作后恢复正常或减轻。
3·Methods 50 patients received standard pure - tone and extended high frequency audiometry for hearing measurement.
方法对50例压力性鼓膜穿孔患者的常频和扩展高频测听的听阈结果进行分析。
4·The hearing screening of the children surveyed by audiometry instruments.
用测听仪器检测受调查儿童。
5·Methods ABR tests were evaluated in 30 traumatic perforation of tympanic membrane cases (30 ears) and compared with the results of pure tone audiometry.
方法应用abr方法对30例(30耳)外伤性鼓膜穿孔进行测试，并将其结果与纯音电测听结果进行对照。
