Advances in Architectural Acoustics and Vibration: Current Progress, Emerging Challenges, and Future Research Directions

Architectural acoustics and vibration engineering are rapidly evolving through advances in computational modeling, adaptive systems, intelligent sensing, and material design. Current research increasingly integrates acoustic quality and vibration control with structural resilience, occupant well-being, sustainability, and building performance. However, challenges remain in measurement reliability, multifunctional acoustic materials, multidisciplinary design, and real-time monitoring and control. This Special Issue, “Advances in Architectural Acoustics and Vibration”, comprises ten contributions covering room-acoustic measurement, tunable sound absorption, structural vibration control, thermo-acoustic design, bridge monitoring, heritage acoustics, and sustainable and engineered sound-absorbing materials. This editorial synthesizes these advances, identifies key knowledge gaps, and discusses future research directions, with emphasis on adaptive acoustic systems, bio-based materials, multiphysics optimization, artificial intelligence, digital twins, and data-driven structural health monitoring.
