声阻抗测试是一种客观的测听方法,它对一般行为测听不能配合者,可较准确测出其听力损失水平,并能检查中耳传音结构的情况还可了解脑干听觉通路的功能。本文对87名聋哑青少年的174耳进行了声阻抗测试,并从鼓压声顺曲线和耳内肌反射两方面加以分析和探讨。一般资料本次检查对象为呼市聋哑学校全体学生。将其中有鼓膜穿孔者及语言频率听力水平在55～85分贝,尚有部分语言能力者除外。年龄10岁内有7例,10-15岁64例,16-20岁19例。其中男49人,女38人。使用仪器为GSI-1723型声阻抗仪,探测音为220赫兹。
Acoustic impedance test is an objective method of audiometry, audiometry can not match the general behavior of those who can be more accurately measured the level of hearing loss, and can check the middle ear acoustic structure of the situation can also understand the brain stem auditory pathway Features. In this paper, 174 ears of 87 deaf and dumb adolescents were tested for acoustic impedance, and the acoustic impedance curves and the reflection of the internal ear muscle were analyzed and discussed. General information The inspection object for all students deaf school Huhhot. Among them, tympanic membrane perforation and the frequency of hearing in the 55 to 85 decibels, with some language proficiency excluded. There were 7 cases in 10 years old, 64 cases in 10-15 years old and 19 cases in 16-20 years old. 49 men and 38 women. Instrument used for the GSI-1723-type acoustic impedance meter, probe sound is 220 Hz.
