众所周知,在强烈噪声环境下工作,噪声会干扰语言交谈,这不但影响工作的正常进行,还有可能发生事故。噪声妨碍睡眠和休息,使人厌烦。长期接触强烈噪声后,听觉器官首先受害,以致发生噪声性耳聋。而研究表明,噪声对人体的听觉外系统还有明显的影响,现分述如下: 一、神经系统:噪声通过听觉器官传入大脑皮质和植物神经中枢,引起中枢神经系统的一系列反应。根据噪声强度和性质的不同及接触时间的长短,有不同程度的变化。长期接触高度噪声后,主
It is well-known that when working in a noisy environment, noise can interfere with verbal conversations, which not only affects the normal work but also may cause an accident. Noise hinder sleep and rest, boring. After long-term exposure to strong noise, the first damage to the auditory organs, resulting in noise-induced deafness. Studies have shown that noise on the human auditory and external systems have obvious effects, are as follows: First, the nervous system: noise through the auditory organs into the cerebral cortex and autonomic center, causing a series of central nervous system reactions. According to the different intensity and nature of noise and the length of contact time, there are varying degrees of change. Long-term exposure to high noise, the Lord
