随着现代工业的发展,噪声危害日益严重,噪声病患者越来越多。 在日常生活中,谈话声音的强度对听觉毫无损害,而生产中的噪声强度则远远超过正常人听力适应音响的范围。长期在噪声环境下工作的工人,由于持续不断地受到噪声刺激,耳感受器易发生器质性病变,暂时性听力损失,逐渐加重 With the development of modern industry, the noise damage is more and more serious, and more and more people are suffering from noise. In everyday life, the intensity of the talking voice has no harm to hearing, and the noise intensity in production far exceeds the range of normal people’s hearing adapting sound.
