What are the acoustic properties of concrete benches in outdoor public spaces?

Concrete benches in outdoor public spaces exhibit unique acoustic properties that influence sound reflection and absorption. Due to their dense and rigid material, concrete benches tend to reflect sound waves rather than absorb them, which can amplify noise in busy areas. This characteristic makes them less ideal for quiet zones but effective in open, lively environments where sound dispersion is desired. The shape and placement of concrete benches also play a role in their acoustic performance; curved or angled designs can diffuse sound, while flat surfaces may create echoes. Understanding these properties helps urban planners and designers optimize public spaces for both functionality and auditory comfort. Additionally, combining concrete benches with softer materials like wood or greenery can balance acoustics, creating more pleasant outdoor environments.
