M. Noise Pollution in Zahedan and Residents’ Knowledge About Noise Pollution,
Context: Noise is considered one of the most pervasive and harmful agents in crowded cities. The aim of this study was to determine the exposure rate to noise pollution of residents on the main streets of Zahedan city in southeastern Iran and the knowledge and attitudes of these residents concerning noise. Evidence Acquisition: Noise was measured for three consecutive weeks in the OctoberNovember areas of the city in 31 test locations, using a CEL-440 Classic sound level meter and analyzer during the noisiest hours of the day (07:00 to 22:00). Using a validated questionnaire, data were collected from 400 subjects to estimate their knowledges and attitudes about noise pollution. Results: The average noise level in the main city streets during the day was 75 ± 2.96 dB. The mean age of participants was 31.9 ± 11 years. Approximately 82.3% of the subjects tested reported that street noise pollution was too high, and 48% suggested that the best way to decrease city noise pollution was to enhance people’s knowledge of the problem. Furthermore, 65.8% of the subjects stated that street noise is a cause of stress. There was a significant association between noise levels and subjects’ sleepiness (P < 0.05). In addition, noise pollution in Zahedan city streets was found to be higher than standard levels. Conclusions: It was concluded that appropriate traffic management and a health promotion program are essential for increasing the residents’ understanding about how to improve the current noise pollution situation.
