As we have seen throughout this research, white infrastructure is an inexorable part of the landscape. It is an incredibly powerful and sensitive tool that allows landscape architects to listen, observe and contribute to the composing of the soundscape. It unravels a deeper and more sensitive understanding of the environment. Sound as part of the ecosystem is therefore crucial to the development of today's urban ecosystems, which are faced with many nuisances. It is a tool that can create healthy ecosystems if it is taken into account in the processes of urban planning in a framework of ecological transition.
Acoustic ecology relates the sound dimension with the physical space and all living things. A study on the sound balance, mechanical, human and natural sounds, informs on the animation of the physical space and on the quality of the sound environment that encompasses it. By reading landscapes with the ears-or rather listening to it, the landscape designer will be able to reshape the acoustic landscape by shaping the physical space and defining sound sources.
Although urban sound is generally perceived as unwanted noise and is characterized in negative terms, acoustic urbanism is not simply a matter of treating noise pollution, but also of creating urban ambiances on a human scale. The notion of a white infrastructure thus adds another sensory dimension to the tangible world of the green and blue infrastructures and proves to be an ecological infrastructure functioning as a link between all other frameworks.
In conclusion, it is not by simply adding “natural areas” that we make space for biodiversity to live in an urban environment. The greening of cities should go hand in hand with the balancing of soundscapes.
Composing an eco-acoustic city is therefore a work of balance and equilibrium, where the notion of ecotones is questioned in its multi-dimensionality. White infrastructure allows an additional framework necessary to conceive the landscape and makes way for the creation of space for the non-human, for the human, but also for the dialogue between all.
