Abstract :
Metro rail systems, which provide efficiency
and speed, have revolutionized urban travel. However,
the subsequent influence on environmental acoustics,
notably noise pollution, needs further examination. This
study evaluates noise pollution from the Dhaka metro
rail along an 11.7 km segment, focusing on 27 monitoring
points across commercial, mixed, and residential areas.
Sampling on working and non-working days,
representing a three-shift day, revealed average morning
noise levels during working days (72 dB to 78.7 dB),
increasing in the afternoon (76.2 dB to 83.6 dB), and
peaking in the evening (80.8 dB to 89 dB). On non-
working days, morning levels ranged from 69.1 dB to
73.1 dB, with afternoon and evening levels at 75.2 dB to
81.6 dB and 75.2 dB to 84 dB, respectively. Identified
noise levels at specific locations underscored the need for
managing metro rail-induced noise pollution, especially
in commercial zones during working days. To address
this issue, the research recommends implementing noise
reduction measures and planning strategies to minimize
disturbances in sensitive areas, ensuring a sustainable
and harmonious urban environment.
