听力是人类认识自然和改造自然的重要生理机能,同时有声语言也是互通信息、交流思想的重要工具。现代化工业生产和各军兵种对听力的要求很高,规定了听力障碍者的就业、升学、征兵的限制条件,这都证明了听觉功能对工作和生活的重要意义。我国卫生界对儿童少年听力的研究数量较少,这和听力研究测试的设备条件要求较高有一定的关系。我国学生体检时对听力检查的方法尚不统一,徐明兴等提倡用机械秒表的振动声,在安静的房间内检查听觉功能,基本上属于定性的方法,深入研究听觉对各种频率声音的反应,就无法完成。用音叉测试听力,虽进了一步,但在现场实际应用仍有一定的困难。近几年我国应用听力计研究学生听力逐步开展起来,但由于设备较复 Listening is an important physiological function of mankind’s understanding of nature and nature. At the same time, spoken language is also an important tool for exchanging information and exchanging ideas. Modern industrial production and various branches of the armed forces have high requirements on hearing, which stipulate the conditions of employment, promotion of college entrance and the conscription of hearing-impaired people, which prove the importance of auditory function to work and life. The research on hearing ability of children and adolescents in the Chinese health community is relatively small, which is related to the higher equipment requirements for hearing research and testing. Our students check the hearing method is not uniform, Xu Mingxing advocated the use of mechanical vibration stopwatch, in a quiet room to check the auditory function, basically a qualitative method, in-depth study of the auditory response to a variety of frequency sounds, Can not be completed. With the tuning fork test hearing, although a step forward, but the practical application in the field there are still some difficulties. In recent years, China’s application of audiometry students gradually carry out hearing, but because the device is more complex
