[Criteria for the further employment of persons with hearing damage in noise areas (author's transl)].

The possibility of further employment of workers in noise areas must be judged by the specific criteria of "Principle No. 20" of the Professional Associations. However, in many cases of already existing hearing damage it is possible to avoid a change of working place for the time being and to rate "No objection on health reasons under certain conditions". In cases of noise-induced, already existing hearing loss, a change of working place is generally not necessary if the worker uses ear protectors. There should also be no general objection in cases of pure disturbance of sound conduction. In combined hearing losses and pure labyrinthine deafness not created by noise, it must be supposed as a general rule that the worker is not fit for further working in noise areas. However, in special cases carefully analysed as to anamnesis and development, even a worker with such types of hearing loss might under special precautions be retained in the noise area.
