چکیده
تزئینات در معماری ایران به دلیل ماهیت عمدتاً بصری‌شان،بیشتر مورد توجه نظریه‌پردازان و تحلیل‌گران از طریق دیدگاه‌های زیبایی‌شناختی و فرهنگی قرار گرفته است.با ورود نرم‌افزارهای شبیه‌سازی و تحلیل سازه،سالیان است که تحلیل جنبه سازه‌ای و دینامیکی این نوع تزیینات نیز از نظر علمی مورد مطالعه و آنالیزقرار گرفته است.در ادامه،یکی از جنبه‌های مهمی که باید مورد مطالعه وسیع قرار گیرد،طرح بحث و تحلیل چالش‌های پیش‌رو در وجهه آکوستیکی بناهاست.این پژوهش یک بررسی سیستماتیک از چگونگی تأثیر سیستم‌های تزئینی معماری بر ویژگی‌های انتشار و پاسخ آکوستیکی در فضاهای معماری محصور را ارائه می‌دهد. این مطالعه از طریق روش‌شناسی تجربی کنترل‌شده با استفاده از مدل‌های هندسی ساده مشتق‌شده از تزئینات مقعر ایرانی، اثرات آکوستیکی قابل اندازه‌گیری تعبیه‌شده در اصول معماری ایرانی را نشان می‌دهد. این پژوهش از عناصر نیم‌کره‌ای در محیط‌های محفظه‌ای کنترل‌شده برای آنالیز الگوهای انتشار صدا، ویژگی‌های بازتاب و تغییرات کلی پاسخ آکوستیک استفاده می‌کند.یافته‌ها نشان می‌دهد که این سیستم‌های تزئینی به‌طور قابل توجهی رفتار آکوستیکی را از طریق سه مکانیسم اصلی تغییر می‌دهند:اثرات بی‌نظمی سطح بر انتشار صدا،رزونانس ناشی از حفره‌ها،و کنترل الگوی انعکاس هندسی.نتایج تجربی کاهش 30 درصدی در حداکثر دامنه،کاهش 57 درصدی در دامنه RMS،و بهبود 80 درصدی در زمان واپاشی را نشان می‌دهند.این پژوهش اعتبارسنجی از اصول طراحی آکوستیک که قبلاً مستند نشده بودند را ارائه داده و همسویی قابل توجهی میان شیوه‌های معماری سنتی و نتایج کاربرد آکوستیکی قابل اندازه‌گیری را نشان می‌دهد.این نتایج و تحلیل‌ها سعی در ارائه مباحثی در باب تزئینات معماری ایرانی به‌عنوان راه‌حل‌هایی برای توسعه سیستم‌های بهبود آکوستیکی یکپارچه دارد.

چکیده English

Traditional Iranian architectural ornamentation has historically been evaluated primarily through aesthetic and cultural lenses, with limited empirical investigation into its functional acoustic properties. This research addresses this scholarly gap by conducting the first comprehensive quantitative analysis of how geometric ornamental systems, including Kar-bandi, Yazdi-bandi, and Muqarnas, influence sound behavior in enclosed architectural spaces.

Through controlled experimental methodology employing multi-domed hemispheric elements that replicate fundamental Kaseh-sazi geometries, this study examines the acoustic conditioning effects of these traditional design elements. The investigation bridges historical architectural practice with contemporary acoustic science by demonstrating how master builders intuitively incorporated geometric patterns to achieve specific acoustic outcomes. Our findings reveal that these ornamental systems create measurable modifications in sound propagation, reflection patterns, and overall acoustic response, providing empirical validation of traditional Iranian acoustic design principles.

The research employs mathematical modeling alongside experimental observation to quantify the acoustic impact of these geometric forms, establishing a scientific foundation for understanding the dual aesthetic-functional nature of Iranian architectural ornamentation. This work contributes to both historical architectural documentation and modern acoustic design practice, demonstrating the continued relevance of traditional building knowledge in contemporary applications. By documenting and validating these acoustic principles, the study preserves important cultural architectural wisdom while advancing the field of architectural acoustics through quantitative analysis of historically-informed design strategies.
