译文修改:关于Hearing protection? 请有兴趣的朋友修改一下以下译文: whenever feasible, engineering controls should be applied first. however engineering controls are not always practical or do not effectively reduce noise to acceptable levels. in this case personal hearing protection is needed. 只要切实可行,工程控制是首选措施。但是,工程控制不会一直有效的减少噪音达到合理的标准。这时候就需要听力保护装置。 there is no cure for hearing loss due to “insult” noise (i.e. ipods, loud music). 由于 “损害”噪音(例如ipod音乐播放器、喧闹音乐),所以对听力损失无治疗作用。 查看更多
