다시 뛰는 공정도시 서울!

초록

This study evaluated noise levels, and noise generation processes, on large
construction sites. This provides basic data for the future noise reduction management
policies of Seoul. In evaluating the noise levels of construction sites, it was found that
the noise level of the roadside area was higher than that of the residential area. This
may be because the roadside noise level at the construction site, 50.0∼65.0 dB(A), was
affected by the noise of the road traffic. Considering noise levels over time, the time of
construction was clearly noisier than the non-construction time, as would be expected
given the use of heavy construction equipment such as bulldozers and breakers. In a
typical 24 hour period, the noise level decreased rapidly from 00:00 to 4:00 am and
rose again after 6:00 am. It peaked at 8:00 am becoming fairly steady, beginning only
to decrease after 11:00 pm. In evaluating the noise level of each process, the three sites
tested showed the noise levels of foun
