耳的损伤最常见于柯蒂氏器,其受损的部位和程度取决于噪声的频率、强度和感受器本身的质。作者考察了33个国家有关噪声的劳动法规,连续噪声的限度一般均为85dB(A)或90dB(A)。不少国家规定对噪声暴露者进行定期听力检查,英国健康与安全组织还规定对不同年龄的工人听力损失水平的处理(表1)。表中警告级是指必须佩戴耳保护器,治疗级是指必须进一步采取医疗措施。 Ear damage is most commonly seen in the Corti, the extent and location of the damage being dependent on the frequency, intensity and nature of the sensor itself. The authors examine labor laws and regulations on noise in 33 countries. The limits of continuous noise are generally 85dB (A) or 90dB (A). In many countries, regular hearing tests are conducted on noise-exposed people. The UK Health and Safety Organization also provides for the treatment of hearing loss of workers of different ages (Table 1). The warning level in the table means that the ear protectors must be worn and the therapeutic level means that further medical treatment must be taken.
