工业噪声是指生产环境中产生的生产性噪声。长期接触噪声对人体会产生危害,其危害程度主要取决于噪声强度(声压)的大小、频率的高低和接触时间的长短。噪声对人体的影响是多方面的。50dB(A)以
Industrial noise refers to the production of noise in the production environment. Long-term exposure to noise on the human body will produce harm, the degree of harm depends on the size of the noise intensity (sound pressure), the frequency of the length of the contact time. The impact of noise on the human body is manifold. 50dB (A) with
