Analysis of noise levels caused by various types of trains

Abstract

A passing train is a source of the noise. Noisy is an unwanted sound from a business or activity at a certain level and time that can cause public health problems and environmental comfort. Noise is one of the problems for environmental health. According to the World Health Organization (WHO), in 2000 there were 250 million (4.2%) of the world population experiencing hearing loss due to noise and around 140 million (50%) were in Asia. A passing train is a source of the noise. In this study the measurement of daytime noise level (Lsm) and momentary noise level (Lek) at several points along the Cirebon-Cepu railway. The daytime noise level (Lsm) is measured for 24 hours for each point while the instantaneous noise level is measured from 5 meters, 10 meters, 15 meters and 20 meters from the rail. Noise level at night (Lsm) and momentary noise level (Lek) which is measured is the noise level caused by various types of trains that are passing. From the research that has been done, the noise level in some places has exceeded the Threshold Value. The highest noise level of Nighttime at Cirebon Prujakan Station is 78 dBA for Special areas, while the biggest increase in momentary noise is caused by a freight train of 30 dBA in Pulosaren Settlement.
