Christine Guillebaud, a social anthropologist and an ethnomusicologist, is a Research Fellow at the French National Centre for Scientific Research (CNRS). She belongs to the Research Centre for Ethnomusicology (CREM-LESC), located at the University of Paris Nanterre. Her academic interests include anthropology of sound, sound studies and the study of urban ambiances. She is currently leading the MILSON research program (milson.fr), dedicated to the study of sound environments in their sociocultural context of production and perception. She has carried out long-term fieldworks in India and edited the volume Toward an Anthropology of Ambient Sound (Routledge, 2017). Previously, she has published numerous articles and edited volumes on musical creation, multimodality, cultural heritage, intellectual property and sound humour.

Catherine Lavandier holds a civil engineering diploma and is professor in building acoustics at the civil engineering department of the technological institute in the University of Cergy-Pontoise, France. Her academic interests include room acoustic quality with a psychophysical approach (her PhD focused on the acoustic indicators needed to characterize the acoustic quality of concert halls) and soundscape quality with an ecological approach. She is regularly involved in French national or European projects whose common aim is to link the physical world of acoustics to the sound perceptions or to the sound representations of people. She participated in the European research network COST TD0804 Soundscape of European Cities and Landscapes. Currently, she works on the audio-visual interactions for outdoor and indoor environments.
