| Abstract: | In 1929, noise-induced lesions were accepted for the first time into the list of occupational diseases. Only "deafness or impairment of hearing bordering on deafness caused by noise" in workers from factories working and processing metals was recognised. Today the VII. Occupational Diseases Order is in force, according to which notifications and compensations may be carried through without regard to the type of factory. The effect of noise is divided into two large groups: 1. General "autonomic" reactions, 2. damage to the organ of hearing. For point 2 there are accurately defined concepts, specifications for the protection and detection of workers exposed to noise and methods of investigation. But there are also a number of problems in the sphere of the expert opinion. There are some difficulties with regard to preventive measures in the use of personal noise protection. Prominent in prophylaxis are sound level measurements. |
