Natural and hybrid-ventilation systems have gained popularity in recent decades with benefits ranging from lower energy consumption and sustainability to human comfort and well-being. While natural and hybrid-ventilation systems have the potential for lower background noise conditions than typical mechanically ventilated or air-conditioned rooms, stringent sound insulation criteria associated with performance spaces often render natural ventilation too costly and onerous. Small pressure differentials are usually required to drive a natural ventilation strategy, which usually requires low airflow resistance with large openings, thereby significantly reducing sound insulation performance. Therefore, the vast majority of new auditoria are designed to be mechanically ventilated.
