A holistic approach to different regulations for acoustic improvements in industrial facilities

With the developing technology and mechanization, the number of industrial facilities has increased. It is important for the worker’s physical and mental health to be in suitable working conditions. This paper analyses the regulations applied in the examination and evaluation of the acoustic environment in industrial facilities. The European Parliament and Council Directive, the United States, Singapore, Canada, Australia, Mexico, Japan, and WHO principles were analysed in detail. Simultaneously, analyses were conducted on the auditory perception of the workers in industrial facilities. As a result of the study, 85, 87, and 90 dBA noise exposure levels were determined for 8 h in different regulations examined. It has been determined that the regulative systems for the auditory perception of the workers in industrial facilities are insufficient. It was found necessary to develop regulation systems for evaluating noise exposure levels and the auditory perception of the workers together. It is important for the occupational health and safety of workers to develop a holistic approach in the update and revision of international regulation and to evaluate the control mechanisms within this scope. The protection of mental and physical health of the workers is presented as the most fundamental requirement. Moreover, it should be ensured that the noise control measures that can be taken (at the source, at the transmission path, and at the receiver) are formed by reducing the noise exposure and increasing the auditory perception of the workers in a positive view.
