Abstract :Noise measurements were made for 16 relevant outdoor points in the central campus area of Yıldız Technical University. All measurements were performed in accordance with Turkish Standards using an HD 9019 sound level meter. A new and sophisticated modelling technique called artificial neural networks was used to model the variation of noise levels from traffic around the campus area. The model inputs were the position of the measurement station, the geographical situation between the noise source and the measurement station, wind speed and direction, air temperature and relative humidity, and time of day. All parameters were measured throughout the study for 5 months.
