Designing spaces that are both well ventilated and quiet has always been difficult. Openings that allow fresh air to circulate—such as vents and ducts—also let noise pass through. Meanwhile, materials that absorb sound, like thick foam panels, often block airflow. This trade-off has limited how engineers control noise in buildings, vehicles, and machinery. Now, a […] The post Scientists discover how to block noise without blocking airflow appeared first on Knowridge Science Report.
