Green roofs for acoustic insulation and noise reduction Universiteit Gent
Green roofs are able to reduce the sound exposure near or inside a building by mitigating diffracting sound waves over (parts of) roofs and by reducing sound transmission through the roof system. Commonly used porous growing substrates were shown to have good sound absorbing properties when dry. Since roof finishing materials of nonvegetated roofs are most often rigid, there is a large potential to attenuate sound waves diffracting over the ...
