It was also found that Ramkhamhaeng, Sathorn, Silom, Lat Phrao, Vibhavadi Rangsit and Lat Krabang road have average noise levels up to 70 dB(A). The major causes for these high levels were traffic,construction and airports, totaling up to 93.25%. Noise levels from traffic were found to be more than 90 dB(A), especially due to superbike/motorcycle, tuk-tuks and 10-wheeled truck. The traffic crisis significantly increases during the time of Songkranfestival and new year festival occurred noise pollution crisis on roads. The study also found the construction of sky train and intersection bridges to be disturbingly loud. As aforementioned, one of the major sources of noise pollution in the city is airports. There are two airports located in Bangkok and each of them produce very high and deadly levels of noise.
