Space & sound characterisation of small-scale architectural heritage: an interdisciplinary, lightweight workflow

This contribution reports on a data acquisition and processing chain the novelty of which is primarily to be found in a close integration of acoustic and visual/metric data. Its outputs pave the way for proportion-as-ratios analyses, as well as for the study of perception aspects from the acoustic point of view. Ultimately, "perceptive" data will be related to "objective" data such as acoustic descriptors or architectural metrics. The experiment is carried out on a set of fifteen "small-scale" rural chapels, which is a corpus intended at fostering cross-examinations and comparative analyses. The specificity of this corpus in terms of architectural layout, of use, and of economic and access constraints, will be shown to have had a significant impact on the technical and methodological choice made all along the acquisition and processing.
