“…However, installing such rigid cylinders in the air cavity may obstruct the airflow. Recently, Li et al [88] attempted to establish simple empirical models for predicting transmission loss performance across plenum windows. A total of fourteen full-scale plenum windows were included in the study, and their parametric analysis was performed.…”

In the past two decades, acoustic metamaterials have garnered much attention owing to their unique functional characteristics, which are difficult to find in naturally available materials. The acoustic metamaterials have demonstrated excellent acoustical characteristics that paved a new pathway for researchers to develop effective solutions for a wide variety of multifunctional applications, such as low-frequency sound attenuation, sound wave manipulation, energy harvesting, acoustic focusing, acoustic cloaking, biomedical acoustics, and topological acoustics. This review provides an update on the acoustic metamaterials’ recent progress for simultaneous sound attenuation and air ventilation performances. Several variants of acoustic metamaterials, such as locally resonant structures, space-coiling, holey and labyrinthine metamaterials, and Fano resonant materials, are discussed briefly. Finally, the current challenges and future outlook in this emerging field are discussed as well.

“…One of the major objectives of the present study is to develop a generalized sound transmission loss prediction scheme to cover façades with multiple plenum windows and have it validated using data from extensive site measurement. One starts with the empirical plenum window traffic noise transmission loss (TLtraffic) prediction scheme for a single standalone plenum window developed by Li et al [25] :…”

“…Plenum windows have become more and more popular recently [23,24], but the sound transmission loss across a plenum window remains hard to predict in practice. The authors have recently proposed an empirical model for predicting the traffic noise transmission loss across a plenum window based on the results of parametric laboratory tests and site mockup data [25].…”
