| Ringkasan: | Noise is one of the most persistent physical contaminant in human environment.
Especially in the developed countries, the technological deveIopment and the growth
of population are key factors in the increase of noise pollution. According to the
Occupational Safety and Health Administration (OSHA), noise is one of the most
common health hazards in the construction industry. As stated by Ballesteros et al.,
(2010), noise is one of the most important acoustic pollutants in the nowadays
society, as it is present in most of people's activities; consequently, not only the
workers of certain sectors, but all the citizens, are exposed to high noise
disturbances. In order to study the noise criteria in MRT infrastructure construction,
some parameter should be included. The study included the measurement of noise
level at Bukit Bintang MRT Station and Kajang MRT construction site. In addition,
the actual level of noise measuremenbis compared with the theoretical permissible
noise based on existing predetermined guideline and standards. Later, the noise
criteria for selected construction activites related to railway construction project have
been proposed. Sound Level Meter (SLM) was used to measure the noise level for
selected site that proposed by Land Public Transport Commission (SPAD). The
measurement shows that the ambient noise of this site exceeded the limitation
provided by Malaysian Department of Environment, (2007). For the commercial area
especially at the Bukit Bintang MRT construction site, 78.84dB was recorded at the
distance of 23m from the noise source. For the critical noise level, the noise level for
deep excavation work was 88.92dB at thelSt 3m whereas the noise level for the bore
piling work was 92.54dB at the 1" lm. Based on the survey, Bukit Bintang MRT
station has the highest noise pollution due to the busiest traffic in the city. |
