噪声单独作用或与其它有害因素联合作用对听觉系统、心血管系统、骨骼系统、生殖发育系统、免疫系统等产生一些不良影响，长期处在强噪声环境中还可能产生一些精神心理症状。持续暴露在较高水平的噪声中（主频率在８００ＨＺ以上）会损伤内耳的听觉细胞，诱导不可逆的听力丧失 Noise alone or in combination with other harmful factors have some adverse effects on the auditory system, cardiovascular system, skeletal system, reproductive and developmental system, immune system and the like. Long-term exposure to strong noisy conditions may also cause some psychotic symptoms. Continued exposure to higher levels of noise (dominant frequencies above 800 Hz) can damage auditory cells in the inner ear and induce irreversible hearing loss
