| dc.description.abstract | As the population of Indonesia continues to rise, the country's demand for various modes of
transportation also increases. The loudness of traffic noise is increased by speeds and numbers of
vehicles. Engine, exhaust, horn and tires causes the vehicles noises. This study aims to investigate the
noise level at the intersection between Dr. Mansyur Street and Setia Budi Street in Medan using Sound
Level Meter. We intend to compare the measurement results with the noise level quality standard
(KepMenLH No. 48 tahun 1996), explore the correlation between traffic volumes and noise reduction.
In addition, we intend to identify the most effective means of noise reduction. The approach employed
to minimize noise level was based on KepMenLH No.48 Tahun 1996, with the Sound Level Meter serving
as the research instrument. The estimation of traffic volume is conducted for 24 hours and separated
into two periods, weekends and weekdays, at 30 locations. The results of the measurements are then
compared to known standards. SPSS was used to determine the effect of correlation and linear
regression tests. The intersection of Dr. Mansyur and Setiabudi streets was plotted using the application
Surfer version 16 to determine the noise control management. This investigation revealed that the
weekend noise levels (LSM) are the highest at 28 locations (70.0 dBA) and the lowest at 11 locations
(63.2 dBA). On weekdays, the noise intensity (LSM) is loudest in 15 places (74.7 decibels) and quietest
in 20 places (66.8 dBA). The results are more significant than the control variable, with a value of 70
dBA. Regulation of vehicle horns, restrictions on vehicle modification, the installation of street signs,
and a greater range in the sound-safe distance across noise sources connected to land-plot management
are all viable alternatives to noise-level control. This research was conducted in October 2021. | en_US |
