Decorating windows for optimal sound transmission

Glass windows typically offer some amount of sound proofing, sometimes unintentionally. In general, ventilation is required to achieve large sound transmission. But some applications -- like gas explosion studies -- require a transparent partition that allows for acoustic propagation without the presence of airflow. In those cases, ventilation is not allowed. Researchers discuss a layered glass material they developed that allows for efficient sound transmission with no air ventilation.
