Objectives: This survey was conducted to provide the fundamental data on trends of noise level to improve of noisy working environment and to prevent of hearing loss in the manufacturing industry. Materials and Methods: The subject of this investigation was noise level of the 34 noisy processes among 92 manufactories of 9 industries in Pusan area. Study period was Jan. 1 1996 to Dec. 31 1998. Results: Geometric mean concentration and standard deviation for several manufactories were as follows. Food products and beverages, 78.1±1.16dB(A); manufactories of textiles. 82.2±1.04dB (A) ; tanning and dressing of leather (manufactories of luggage, handbag, saddlery, harness and footwear), 83.0±1.04dB (A) ; manufactories of wood and products, of wood and cork, except furniture, manufactories of articles of straw and plaiting materials. 93.3±1.02dB (A) ; manufactories of rubber and plastics products, 81.8±1.04dB(A) ; manufactories of basic metals, 86.4±1.06dB(A) ; manufactories of fabricated metal products, except machinery and equipment. 84.3±1.05dB (A) ; manufactories of machinery and equipment, not especially classified, 84.8±1.05dB(A) ; manufactories of furniture (manufacturing not especially classified) 84.9±1.03dB(A). Geometric mean concentration of noise in the 1st lumbering(92.9±1.02dB(A)) and the 2nd lumbering(93.8±1.02dB (A)) process of manufactories of wood and products of wood and cork, except furniture, sanding(92.4±1.04dB (A)) process of manufactories of basic metals industry were higher than the permissible noise exposures limit value. Conclusions: In the industrial hygienics aspect, special attention and management of working environment should be conducted for the manufacture of wood and products of wood and cork, except furniture, manufacture of articles of straw and plaiting materials and manufacture of basic metals industry in Pusan area.
