Analysis Of Noise Intensity In The Railway Facility Maintenance Work Environment

Abstract

One example of work  that has a high  risk of  work in the  world  of railways is the  maintenance of railway facilities.  One of  the  risks posed comes from the  noise generated  from  the maintenance  activities carried out.   This study used a Soundlevel Meter tool to measure noise intensity in  the railway facility maintenance  work environment. The measured noise level  is the  equivalent noise  level.   This study also seeks to find out the  impact and what impact prevention steps have been taken. The equivalent noise level in the work environment, especially in the final test,  is 90.82 dB. The impact of noise experienced includes physiological disorders, psychological disorders and social disorders. Common physiological disorders experienced by facility nurses are the appearance of nausea, insomnia and shortness of breath. This feeling of discomfort will diminish and become less and less felt after some time. In the sense of hearing is also not found permanent interference. Psychological disorders can be in the form of discomfort, lack of concentration, insomnia, emotional instability, feelings of irritability to colleagues and superiors, and feeling tired quickly. One form of social disorder that can appear is masking effect, which is a lack of clear communication due to sounds that cover hearing. Noise control carried out is by isolating (separating facility nurses from noise sources), periodic toolbox meetings,  administrative arrangements (setting working hours and facility nurses), providing K3 training, routine health checks, and using PPE properly and correctly.
