Since the 80s, several researches have developed the theoretical notions of sound effects, sound proxemy, city sound identities, sound comfort, architectural sound prototypes which were meant to help designers consider sound in their projects. Nevertheless, taking care of the inherent sound dimensions in architectural urban projects remains an unresolved challenge. The researches of the last 30 years have shown how the sound environment qualities are forgotten in favour of visual qualities. This article presents a new method dedicated to generating simple sound sketches for architectural conception while preserving the complexity of acoustic simulation. This paper argues that the Esquis'sons! sound sketch tool reconfigures architectural design by considering an innovative view its the temporality, allowed by numeric designing tools able to intervene and offer a continuous feedback regarding sound environment.
