Abstract
Railway is one of the most important means of transportation for public and goods. However, its engines make unwanted noise, which is unpleasant to the general public and workers. The purpose of this study was to determine the noise level at locoshed, shop, fuel ¬lling station and load test section of Pakistan Railways Karachi. The noise levels of the selected locations were measured with the help of CR-262A, Sound Level Meter after calibration with an acoustic calibrator. The workers were personally interviewed and a questionnaire was also distributed, ¬lled up and collected for the determination of noise impact on workers’ performance. An analytical hierarchy process model was used for the analysis of noise impact with di erent alternatives namely locoshed, shop, load test and fuel ¬lling station. The maximum average and peak noise level at locoshed, locoshop and load test sections was found to be exceeding 1.3 to 1.5 times from World Health Organization standards. It was discovered from the model results that there were inconsistency of 0.45. The study revealed that the noise level was more than standards at the selected locations and performance of the employees and workers were seriously a ected due to the critical conditions at and near the workplace.
