The paper examines the different aspects of the diagnosis of noise induced hearing disability and handicap. In the author's opinion a diagnosis of this kind can be made only if both an occupational acoustic trauma and a hearing disability or handicap are present. An occupational acoustic trauma can be considered to be present if the subject works in a noisy environment, if there are no auditory diseases other than of occupational origin, and if the audiometric threshold is neurosensorial, bilateral, more elevated at the higher frequencies and higher than the threshold of subjects on the same age but not exposed to industrial noise. On the other hand, the authors deem that there is a loss of hearing function when hearing disability and handicap are present according to the WHO definition. An experimental model is proposed that will establish the presence of hearing disability and handicap.
本文探讨了噪声性听力残疾和听力障碍诊断的不同方面。作者认为，只有在存在职业性听觉创伤以及听力残疾或听力障碍的情况下，才能做出此类诊断。如果受试者在嘈杂环境中工作，除职业性起源的听觉疾病外没有其他听觉疾病，并且听力阈值是神经感觉性的、双侧的、在较高频率处更高且高于同年龄但未接触工业噪声的受试者的阈值，则可认为存在职业性听觉创伤。另一方面，作者认为，根据世界卫生组织的定义，当存在听力残疾和听力障碍时，存在听力功能丧失。本文提出了一个实验模型，该模型将确定听力残疾和听力障碍的存在。
