Sacred Sound System Enhancement Study
The Great Mosque of Damascus (Umayyad Mosque), inscribed on UNESCO's World Heritage List since 1979, requires comprehensive sound system enhancement to meet modern acoustic performance standards while preserving its exceptional cultural and architectural heritage. This study presents a world-class audio engineering solution that balances technical excellence with heritage preservation principles.
يتطلب الجامع الأموي (الجامع الكبير في دمشق)، المدرج في قائمة مواقع التراث العالمي لليونسكو منذ عام 1979، تعزيزاً شاملاً لنظام الصوت لتلبية معايير الأداء الصوتي الحديثة مع الحفاظ على تراثه الثقافي والمعماري الاستثنائي. تقدم هذه الدراسة حلاً هندسياً صوتياً على مستوى عالمي يوازن بين التميز التقني ومبادئ الحفاظ على التراث.
The Umayyad Mosque, constructed between 705-715 CE under Caliph al-Walid I, represents one of the earliest and most influential examples of Islamic architecture. Its Outstanding Universal Value encompasses:
Listed on UNESCO's World Heritage in Danger since 2013 due to ongoing conflict impacts, requiring heightened conservation attention for any intervention projects.
يمثل الجامع الأموي، المبني بين عامي 705-715 م في عهد الخليفة الوليد بن عبد الملك، أحد أقدم وأكثر الأمثلة تأثيراً في العمارة الإسلامية. تشمل قيمته العالمية الاستثنائية:
مدرج في قائمة التراث العالمي المعرض للخطر لليونسكو منذ عام 2013 بسبب تأثيرات النزاع المستمر، مما يتطلب اهتماماً متزايداً بالحفظ لأي مشاريع تدخل.
| Architectural Element | Dimensions | Acoustic Impact | Design Considerations |
|---|---|---|---|
| Main Prayer Hall (Haram) | 136m × 37m × ~20-25m height | RT60: 4-6 seconds, High reverberance | Requires directional speakers, beam steering |
| Central Dome | ~36m height, 15m diameter | Strong acoustic reflections, echo potential | Avoid direct sound excitation, use steerable arrays |
| Courtyard (Sahn) | 122m × 50m open area | Ambient noise, wind effects | Weather-resistant equipment, higher SPL requirements |
| Minarets (3 total) | Heights: 77m, 77m, 45m | Long-distance projection needs | High-power horn speakers, directional control |
| Corinthian Columns | 68 columns, ancient stonework | Mounting constraints, vibration sensitivity | Reversible mounting systems, vibration isolation |
Overall Assessment: IMMEDIATE REPLACEMENT REQUIRED
The existing sound system exhibits severe performance degradation that compromises the mosque's primary function of clear religious communication.
التقييم العام: مطلوب استبدال فوري
نظام الصوت الحالي يظهر تدهوراً شديداً في الأداء يقوض الوظيفة الأساسية للمسجد في التواصل الديني الواضح.
| Component Category / فئة المكون | Brands Identified / العلامات التجارية | Age Range / العمر | Condition Assessment / تقييم الحالة | Replacement Priority / أولوية الاستبدال |
|---|---|---|---|---|
| Speakers (Main) | Dynacord, Inter-M, TOA, PROEL, Turbosound | 15-35 years | Critical - Inconsistent coverage | URGENT |
| Speakers (Support) | UNI-PEX, PASO | 20-30 years | Poor - Frequent failures | HIGH |
| Amplification | Mixed legacy systems | 25-35 years | Fair - Limited functionality | HIGH |
| Audio Processing | Analog mixing consoles | 20+ years | Poor - No digital processing | URGENT |
| Microphone Systems | Assorted analog wireless | 15-25 years | Fair - Interference issues | MEDIUM |
Status: Data marked as PRELIMINARY REFERENCE ONLY
Comprehensive acoustic simulation (EASE/ODEON/CATT) required before final design implementation.
الحالة: البيانات مؤشرة كـ مرجع أولي فقط
محاكاة صوتية شاملة (EASE/ODEON/CATT) مطلوبة قبل التنفيذ النهائي للتصميم.
