This publication, led by Elie Grinfeder, PhD student at the Ecole normale Supérieure and at EAR, reviews the concept of soundscape and, through a functional and source-filter approach, suggests the use of three soundscape categories: the distal soundscape (the spatial and temporal distribution of sounds in a pre-specified area, in relation
to sound propagation effects), the proximal soundscape (collection of propagated sound signals that occurs at a specific position in space) and the perceptual soundscape (individual subjective interpretation of a proximal soundscape). Congratulations to Elie!
