Vietnam is a developing country in Southeast Asia, and it is currently struggling with many environmental issues. The traffic noise in Hanoi and Ho-Chi-Minh city were characterized by relatively high noise exposure levels due to the large number of motorbikes and frequent horn sounds. High noise exposure of more than 75 dB(Ldn) is characteristic of road traffic in many places. On the other hand, casement windows consisting of two wooden frames are widely used in those cities. However, these windows prove to be impermissible to noise level because the window ventilating slits serve as a direct pathway to allow traffic noise to enter the home. The acoustic characteristics of road traffic noise and the casement windows at present are experimentally considered in present work.
