Measurement of impulse noise in the community area near the Rood Tunnel Construction project in Bangkok
Keywords:
impulse noise, construction machine, underground tunnel constructionAbstract
At present, in Bangkok, many tunnels are being built, all of which are in urban areas with densely populated populations. This research studied the impact of impulse noise from construction machinery. A case study of a road tunnel construction project in Bangkok and compare the difference in the impulse noise level of construction machinery to nearby communities with and without construction activities. Impulse noise level (LC, peak 5 min) according to the 2016 A.D. standards of ministerial regulations for management and performance safety measurements were performed by integrating sound level meters during foundation construction for 8 hours, for a total of 7 days at the construction area and in the community (total of 4 stations). Data were analyzed using descriptive statistics, including minimum, maximum, and mean. The differences between groups were analyzed using the independent t-test inferential statistics.
The results of the Area A study showed that the average of LC peak 5 min in the community near the construction site is higher than the construction site with statistical significance at the .001 level (P <.001). The difference between the average of LC, peak 5 min in the community near the construction site during with and without construction activity was found to be no different and during the construction period of Area A, the highest LC peak was 134.6 dB (C). Area B in the construction site had an average of LC, peaking 5 minutes higher than the community near the construction site with statistical signifcance at the.001 level. The difference between the average of LC peak 5 min in the community near the constru ction site during with and without onstruction
activity showed that during the construction activity period, the average of LC peak 5 min was higher than the period of inactivity with statistical signifcance at the.001 level and During the construction period of Area A, the highest Lcpeak was 133.6 dB (C). Therefore, there should be monitoring or measurement to reduce impulse noise from pile drivers and concrete floor drilling, which could decrease the noise levels.
