Megjegyzések:	New constructions can negatively impact the environment and human health. Therefore, noise modelling is employed to predict the environmental noise levels during the Front End Engineering Design (FEED) phase and maintain noise levels below specified limits by applying various mitigation measures, if necessary. In this work, a comprehensive examination consisting of modelling and measurements was conducted to accurately design a noise barrier around a viaduct in a commercial-residential area. The study area comprises 3 towers which consist of 12 retail units that vary in size, 423 residential units, and multiple parking lots. An urban railway viaduct line connecting an International Airport to the center of the city of dense population was established before the construction of the 3 towers. Therefore, the study was prompted due to sleep disturbance complaints from the tower residents caused by the impact of railway noise. Thorough noise measurements were conducted at the most sensitive locations of the towers followed by a noise modelling study (SoundPLAN 9.0 noise modelling software was utilized) to explore diverse noise barrier design solutions, adhering to local standards, as well as ISO and DIN standards to ensure a very high level of accuracy. The findings revealed that noise levels exceeded the limit value for daytime and night-time at all noise receptors with an average difference of 0.2 dB(A) between the measurements and the model. The study evaluated five noise barrier design scenarios, and the proposed noise barrier demonstrated a noise reduction ranging from 5 to 21 dB(A) at different receptors, with an average reduction of 10.8 dB(A).
