Noise emission characteristics of cosmetics manufacturing plants

Recently, a rapid increase in the establishment of cosmetics manufacturing facilities has been observed in Korea because of the growing export of K-beauty products. Many of these factories are certified under good manufacturing practice (GMP) standards and show significant interest in quality management, industrial injury prevention, and productivity enhancement. Among industrial injuries, noise-induced hearing loss holds the largest share, rendering it crucial for industrial injury prevention. Therefore, this study aimed to assess the noise exposure status in cosmetics manufacturing facility spaces. Analysis revealed that the 24-h average continuous noise level (L_eq) was approximately 69.0 dB(A). The measured areas were divided into three rooms based on their purpose, of which the Manufacturing Room showed the highest noise levels ranging from 74.0 to 77.0 dB(A). Additionally, the Blister Packaging and Sealing Room ranged from 64.1 to 66.1 dB(A), and the Box Packing Room ranged from 64.3 to 65.8 dB(A), all within acceptable limits and not exceeding day-night noise correction exposure standards. From the perspective of industrial injury prevention and monitoring, this study aims to implement these measurement results within the metaverse in the future for visualization.
