L'espace public sonore ordinaire : les paramètres de la perception sonore dans les espaces publics : contribution à une connaissance de l'ambiance sonore.

摘要

The particularity and challenge of this research subject lie in the confrontation between the urbanistic vision of the public space, the physical approach to acoustic measurement and the consideration of how the sonic environment is perceived. Several types of public spaces were used to study the assessment of urban sonic ambiances. We problematize our study of the understanding and assessment of sound perception in order to highlight some of its relevant parameters. The methodology was designed to combine perceptive data and physical measurements. The first stage of in situ investigation thus provided a corpus of 174 questionnaires, 513 photographs and 18 non-directive group interviews. Acoustic measurements were then made at the same temporalities. Finally, a second stage of in-depth individual interviews conducted with the 29 participants was completed with the realization of 145 mental mind maps. This multifaceted methodology helped to determine the influence of several parameters such as human presence, nature, the mineral aspect, seasonality and urban forms on the spatial and sonic assessment in public spaces.
