    INSUL software use for predictive assessment of acoustic insulation in partition walls against airborne noise
    (Université Badji Mokhtar Annaba, 2025-10-29) BOULEMAREDJ, Ali; SAIFI, Amel
    Controlling noise transmission in buildings is a key factor for ensuring health, comfort, and regulatory compliance. In Algeria, however, acoustic insulation remains an overlooked aspect in the construction process, particularly for partition walls and floors. This study investigates the acoustic performance of typical partition configurations using INSUL software, an internationally recognized sound insulation prediction tool. The objective of this study is to assess the airborne sound reduction index (Rw, dB) of typical Algerian partition wall configurations using INSUL software, in order to evaluate their insulation performance against international standards. Results demonstrate the significant influence of wall thickness, cavity design, and insulation materials on airborne noise reduction. The findings provide practical insights for architects and engineers to enhance acoustic design from early project stages.

    Room acoustics of Conference Halls and Amphitheaters
    (Université Badji Mokhtar Annaba, 2025-11-18) BOULEMAREDJ, Ali; FARID, Dalel; SAIFI, Amel; IBRIR, Hadi; BENOTMANE, Mohamed Essedik
    Acoustic quality in conference halls and amphitheaters is essential for clear communication, particularly in educational and professional contexts. This literature review examines key acoustic principles and design strategies that affect speech intelligibility and listener comprehension. Drawing on standards, theoretical models, and documented case studies, the review identifies critical factors such as reverberation time, spatial geometry, surface materials, and electroacoustic support. Emphasis is placed on architectural and engineering solutions that enhance clarity and reduce acoustic distortions. The paper consolidates current knowledge to inform better design and renovation practices for speech-focused spaces.
