Description
Summary:This paper is a study on noise level produced by traffic in Putrajaya. The main objective of the study is to employ SoundPLAN Road Traffic Noise Software and Norsonic 118 Sound Level Meter in determining, analyzing and assessing noise distribution levels in Putrajaya with the guidelines recommended by World Health Organization (WHO). Software Application and Field Observation are the methods used in this study. From the test results, there is no significant difference of using SoundPLAN software between manual handling by Sound Level Meter. This is supported by the results of the findings which show that tstat is not exceeded than tcritical by the T-test hypothesis study. There is a relationship between urban noises and traffic volume. The finding of the study also indicated that the distance from the traffic is the main factor to the increment of noise level at Putrajaya. From the analysis, a new noise contour map that covers some part of the districts has been produced. These noise maps have been particularized via software application that provide noise barrier to prevent noise level from disturbing human activities. Based on the study, it can be concluded that 30 % of the measurements from the study area were higher than 75 dB(A) which is exceeded than the limit that recommended by WHO which can effected hearing loss.
