The industrial noise-deafness is often combined with other hearing-impairments. For the "MdE" (reduction of work capacity)--assessment, the expert has not only to think about the pure medical differential diagnosis, but also about juridical relationships and the damage "before" and "afterwards". In this study definitions of the damage "before" and "afterwards" and principles for consideration of MdE-measurements are given. The opinion is represented, that the damage "before" is not only the disease, which existed before noise-exposition. But, the important date for judgement is the occurrence of the event insured. Questions about the over-all judgement for limitable and unlimitable forms of hearing-impairment are explained by examples from the experts experience.
工业性噪声性耳聋常与其他听力损害合并存在。对于“劳动能力降低”（MdE）评估，专家不仅要考虑单纯的医学鉴别诊断，还要考虑法律关系以及损害的“之前”和“之后”情况。本研究给出了损害“之前”和“之后”的定义以及考虑MdE测量的原则。文中指出，损害“之前”不仅是噪声暴露之前就已存在的疾病。但是，判断的重要日期是保险事件的发生时间。通过专家经验中的实例解释了关于可限定和不可限定形式听力损害的总体判断问题。
