Does Noise Affect Workers Stress Levels

Does Noise Affect Workers Stress LevelsNoise is an unwanted sound or sound and can interfere with health, interfere with comfort and can cause deafness. According to Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia No PER.13 / MEN / X / 2011 the noise threshold level (NAV) is set at 85 dBA.

Industrial sectors in developed and developing countries will not be separated from noise problems. Noise is caused by the use of machinery and equipment in the production process. Sound noise is usually caused by a collision or collision of work equipment generally made of metal.

In an industry, production activities occur every day that result in workers exposed to noise every day. A person exposed to noise may be affected by various disorders, especially hearing loss. In addition to hearing loss, other ganggguan that will arise one of them is a psychological disorder. Psychological disorders that will arise from the exposure of noise above 85 dB is a stress that can lead to insomnia, easy emotions and concentration disorders that allow the occurrence of work accidents. Psychological disorders can occur even if the noise intensity is not too high.

Stress is a condition of tension that affects the emotions, thinking processes and conditions of a person. Job-induced stress can arise if the demands of the work environment exceed the ability of the worker to overcome or control it. The sources of stress are from work, emotional or mental workers. Within the scope of employment, job stress is a problem for the health of the workforce. Stress poses a risk of work accident that will cause a lot of material loss and can decrease worker productivity.

According to research conducted by Oktarini (2010) in rice milling companies, the percentage of workers who experience work stress in a rice milling room with a noise intensity of 87 dB for 8 hours is 100%. This means that all workers who work in a rice milling room with a noise intensity that exceeds the threshold have a higher risk of experiencing work stress.

Waves generated from noise can travel through air or other carriers, activating the sympathetic nervous system and hormonal centers in the brain such as catecholamines, cortisol epinephrine (stress hormones) and others. The Hypothalamus-Pituitary-Adrenal (HPA) system is the most important part of the neuroendocrine system associated with the onset of stress. Excess hormone cortisol can impair function in the prefrontal cortex of the emotional center.

If the worker is exposed to a job that exceeds his or her abilities then it will be at risk of experiencing work stress. One source of worker stress is from the work environment like an uncomfortable work environment. Noise in the work environment is one cause of the work environment is not comfortable.

Stress in a work environment caused by noise can be prevented or overcome by using stress management. Stress management not only overcomes stress, but also conducts a learning process on how to cope with stress adaptively and effectively such as by monitoring the work environment, providing noise reduction, machine maintenance, the provision of PPE, and also from the party company may be able to implement the system shift work for the workers so as not exposed to noise for too long.
