چکیده
زمینه و هدف: شهرک صنعتی کاوه با وسعت ۳۰۰۰ هکتار در نزدیکی ساوه، دارای ناحیه مسکونی با بیش از ۲۵۰۰ نفر جمعیت است که در مجاورت صنایع فعال شبانهروزی قرار دارد. این همجواری، ضرورت ارزیابی و پهنهبندی آلودگی صوتی را برای آگاهی از سطح مواجهه و حمایت از مدیریت شهری ایجاد میکند. این مطالعه باهدف سنجش و تحلیل مکانی آلودگی صوتی در زمستان ۱۴۰۳ انجام شد.
مواد و روشها: پژوهش بر اساس استاندارد ISO 1996-1:2016 و پس از پیش مطالعه طراحی گردید. ۴۹ نقطه برای اندازهگیری تراز صوت انتخاب شد. در هر ایستگاه، تراز معادل پیوسته (Leq) با صداسنج TES-1358 ثبت و دادهها با نرمافزار Excel و ArcGIS Pro تحلیل گردید.
یافتهها: تحلیل مکانی نشان داد در روز ۸۸ درصد از مساحت ناحیه مسکونی در معرض تراز بالاتر از ۶۵ dB(A) و در شب ۹۶ درصد بالاتر از ۵۵ dB(A) قرار داشت. میانگین شاخص DNL برابر ۷۱ دسیبل محاسبه شد. تنها بخش کوچکی دارای شدت صدای کمتر از ۴۵ dB(A) در شب بود که با حدود مجاز تطابق داشت.
نتیجهگیری: نتایج بیانگر آن است که ناحیه مسکونی مجاور شهرک صنعتی کاوه در اغلب نقاط در معرض سطوحی فراتر از استانداردها قرار دارد، بهویژه در شب که بسیاری از نواحی بیش از ۶۵ dB(A) را تجربه میکنند. توزیع نامتوازن شدت صوت نشاندهنده نقش منابع محلی و نبود موانع صوتی مؤثر است. یافتهها لزوم بازنگری زیستمحیطی شهرکهای صنعتی و اجرای اقدامات کنترلی همچون دیوار صوتی، کمربند سبز، محدودیت فعالیت شبانه و پایش مستمر را نشان میدهد.

چکیده [English]
Introduction: The Kaveh Industrial Estate spans 3,000 hectares near Saveh and operates continuously. A residential area housing over 2,500 inhabitants is situated directly adjacent to it. Assessing and mapping environmental noise exposure is critical for understanding exposure levels and supporting urban planning and environmental management. This study aimed to evaluate and spatially analyze noise pollution in the adjacent residential zone during the fall and winter of 2024–2025.
Materials and Methods: Following a preliminary assessment based on ISO 1996-1:2016 guidelines, 49 measurement locations were selected. The equivalent continuous A-weighted sound pressure level (Leq) was measured at each site using a TES-1358 sound level meter. Data were processed in Excel and analyzed spatially using ArcGIS Pro.
Results: Spatial analysis revealed that 88% of the residential area exceeded 65 dB during the day, and 96% exceeded 55 dB at night. The mean Day-Night Sound Level (DNL) was 71 dB. Only a minimal portion of the area exhibited nighttime levels near or below the 45 dB permissible limit.
Conclusion: The findings indicate that the residential area adjacent to Kaveh Industrial Estate is exposed to noise levels exceeding standard limits in most locations, particularly at night when sound levels in many zones surpassed 65 dB. The uneven spatial distribution of noise indicates the influence of local sources and a lack of effective sound barriers. These results underscore the need for environmental reconsideration of industrial areas and the implementation of control measures such as noise walls, green buffers, nighttime operation limits, and continuous monitoring.
