Site analysis is evaluated based on numerous factors in the process of architectural design, the achievement of which requires a complete evaluation system and an accurate understanding of it. The present study investigated the factor of noise pollution as one of the significant and influential parameters in the process of architectural site plan analysis. The present study mainly aims for a parametric simulation and evaluation of the noise pollution factor using the environmental impact assessment matrix. The study is quantitative and has been varied out using modeling and simulation techniques. Reputable architectural software such as Grasshopper and Rhino have been used for an accurate evaluation of the parameters. According to the results and based on the simulations conducted in software, determination of the obstacles, and specification of the noise pollution sources, the number of noise pollution production houses through a source is more influential than the intensity of the noise pollution by the same source. Besides, the noise pollution received at each point of a design's context depends on the height of the noise source besides the direct distance from it. Eventually, the environmental assessment matrix was used to specify the suitable and favorable ranges for design based on the impact of noise pollutions. The analytical components of the site such as noise pollution can be more effectively and directly taken into account in the process of design using algorithms and parametric methods so that the analysis and design phases are integrated unlike in traditional methods.
