Abstract

Noise has become an important environmental problem in the world. Noise maps play a crucial role in city planning and improving the quality of life for both urban residents and natural resources. The study aimed to measure noise levels in 84 different locations within the Karasu municipality (Sakarya, Turkey), including different land uses, which are significant sources of environmental noise. The study was conducted over a 12-month period to create monthly, seasonal, and annual average noise maps. Statistical analysis was performed on the collected noise data and noise maps were generated. The results showed that traffic was the main source of noise and that the highest levels (79,90 dB) were observed on Istanbul and Ankara avenues. The study found that noise levels varied seasonally and that noise levels in many parts of the city exceeded the levels permitted by the Environmental Noise Assessment and Management Regulation in force in Turkey. Three types of noise barriers were proposed for three different selected locations. As a result, there was a significant and positive relationship between the effects of the measured noise levels in all seasons on each other. Another result is in relation to the spatial characteristics of the measurement point, the change in noise level is significant. According to the analysis the changes in noise levels in spring and summer and the spatial differences in the points where measurements were taken are seen at a significant level.
