An analysis of railway noise from comparison and evaluation between A-weighted SPL and sound quality indices

A-weighted 음압레벨과 음질 지수의 평가 및 비교를 통한 철도소음의 해석

In the previous studies on railway noise analysis, the main purpose of noise analysis is concerned with the reduction of A-weighted sound pressure level in order to satisfy noise regulations. However, more important facts on noise reduction are the subjective feelings of the human being on noise because people might be annoyed from the noise caused by train. In this paper, railway noise from different type of train are compared using the calculation of sound quality metrics with using strength related method that is calculation of A-weighted sound pressure level.
