Fragen der Lärmminderung in der chemischen Industrie (Geräuschsituation innerhalb und außerhalb der Werke)

Questions of noise reduction in the chemical industry (noise levels inside and outside industrial sites). In the chemical industry there are hardly any noise problems as far as working conditions are concerned. However, certain difficulties are to be expected in the neighbourhood of chemical plant. Open‐air plants require special nosie reduction measures at many individual noise sources. Safety aspects must have priority. The increased demands necessitate inclusion of piping and equipment in acoustic planning. There should be adequate transition zones separating industrial and residential areas, but owing to lack of town planning desirable screening distances hardly exist. New plants can now be built with noise levels some 7 to 10 dB (A), in certain cases even more than 10 dB (A), lower than ten years ago.
