Cairo was recorded the second noisiest city in 2018. Noise pollution can affect badly on human health and daily activities. However, Egypt suffered from limitation of controlling noise's research. Planners and designers should be considering how controlling noise propagation at urban planning through determine the relation between urban morphology and noise paths. Here comes the role of this research, it aims to investigate the effect of some urban morphology parameters on noise propagations at selected case study. It was in Maadi, Cairo. The research workflow contained four stages. Firstly, defining urban morphology and its relation with noise propagations. Secondly, researchers visited the site to collate data and observe the traffic flow on weekdays and weekends during rush hour. Then simulate the selected case study on Predictor - LimA software to predict noise levels and create noise maps. Third, analysis noise maps to determine noise propagations characteries. Finally, link urban morphology parameters as buildings factors, road networks, landuses managements and human behaviours with noise separations. The results pointed out the most essential parameters affecting noise propagation and elaborated the direct relation between noise propagations and urban morphology to determine role of planners, governments, and vehicles owners to mitigate noise propagations.
