چکیده مقاله :
زمینه و هدف: ترددهواپیماهادربافتشهریوسروصدایفرودگاهیکیازآثارنامطلوب ومتداولزیستمحیطی به شمار می رود. گسترشفرودگاه هاسبب شدهاستتاامروزهفرودگاههاومناطقمسکونیبسیاربهیک دیگرنزدیکشوندوهمینموضوعاهمیت بررسیآثارآلودگیصوتیناشیازپروازهواپیماهاراآشکارترمی کند. هدف از این پژوهش، بررسی میزان آلودگی صوتی ناشی از تردد هواپیماها در محدوده ی پیرامون فرودگاه و در مسیر پرواز هواپیماها در شهر اهواز می باشد. روش بررسی: در این پژوهش ابتدا طی یک بازه زمانی4 ماهه و در دو نوبت روز و شب، میزان تراز صوتی در70 ایستگاه که در مسیر پرواز هواپیماها در محدوده شهری واقع هستند، اندازه گیری شد. بعد از آن پرسش نامه های میزان آزاردهندگی صدا توسط ساکنین مناطق مورد مطالعه و کارکنان فرودگاه تکمیل گردید. یافتهها: نتایج حاصل از این پژوهش نشان داده است میانگین تراز فشار صوت در محدوده مورد مطالعه به ترتیب در نوبت روز و شب 69/68 دسی بل و 62/65 دسی بل اندازه گیری شد. در طول مدت سنجش کم ترین تراز فشار صوت اندازه گیری شده با81/ 58 دسی بل در منطقه کوی پاستوریزه و بیش ترین تراز فشار صوت با 76/85 دسی بل در منطقه علی آباد ثبت شده است. بحث و نتیجهگیری: بر اساس نتایج حاصل می توان عنوان نمود که میزان صوت در تمامی ایستگاه های مورد مطالعه دارای حدود بالاتری از استاندارد سازمان حفاظت محیط زیست ایران بوده است.
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.
