Three colors draw the acoustic space of the Esplanade la defense, where each corresponds to a type of sound source. You can notice that on the center platform there is a strong presence of human sounds, in orange, and some points of presence of natural sounds which are in green. And we also see that all this sonosphere that makes up the center public space is surrounded by the pink soundwaves of mechanical sounds.
The district, founded on a network of transport infrastructure, the main source of noise pollution in an urban environment, is isolated from its territory by a ring of noise that is the boulevard circulaire. Its urban landscape makes up its own sonosphere composed by humans and machines where nature is out of tune. This acoustic obstacle accompanies the physical discontinuities and contributes to ecological imbalance.
The ambition of the project is to transform this noise obstacle that is the boulevard circulaire into an ecological interface and to compose urban "promenades", that are favorable to the presence of biodiversity. I approach the boulevard as a spatial interface with the ambition to transform it from an obstacle into an inclusive space of acoustic comfort and dialogue.
RE-ORCHESTRATING THE FLOWS - Territorial scale strategy
On a territorial scale, the study of sound is more a study of understanding the impacts, the sound alterations that contribute to the fragmentation of the urban environment. The previous understanding of the acoustic space in relation to the spatial typologies of La Defense allowed me to get an understanding of the urban ecosystems’s dynamics and the human to nature to road infrastructure flows that animate it. I looked beyond the urban ruptures to have an understanding of the site based on the flows that animate it (El Samman, 2021).
Furthermore, in order to envision the ecological transformation of this urban island, a vision of the flows that I want to establish through the white infrastructure strategy was projected.
