The manufacturing and production of concrete construction building materials creates roughly 10% of global carbon emissions. As a result, architectural engineers are trying to find new ways to reduce the amount of concrete used in their buildings. Less concrete, though, can lead to some major ramifications in terms of the acoustics of a built space. In this episode of Across Acoustics, we talk to Jonathan Michael Broyles (Penn State) about techniques for optimizing the design of concrete slabs used in floors to reduce materials while improving acoustic performance.
