Abstract :

Background and Objective: Airplanes shuttling in urban context and airport noise are considered as common undesirable environmental effects caused by establishment or development of airports. Airport development has decreased the distance between airport and residential area and this highlights the importance of investigating the effects of the acoustic pollution caused by flights. The purpose of this study is to investigate the amount of acoustic pollution caused by flights in an area around the airport and in the direction of airplanes in Ahvaz. Method: For this purpose, the rate of acoustic balance was measured during a four-month intervals in two day and night turns in 2015. In this study, 70 station were selected, in which sound rate was measured with 3 repetitions. Then the questionnaires a noise annoyance were completed by residents of the study area and the airport staff. Findings: According to the results, the average balance of acoustic pressure in day turn and night turn were 68.69 and 65.62 dB respectively. During the measurement, the minimum sound pressure level of 58/81 dB and the maximum sound pressure level of 85/76 dB were recorded in Kooye-Pastorizeh and Aliabad regions. Discussion and Conclusion: Results show that sound value in all the studied stations is higher than the standard of EPA.
