Cathedral acoustics represents a key part of Europe’s intangible cultural heritage at risk of being altered by architectural deterioration or restoration work. This multidisciplinary project, funded by the European Commission through the Marie Skłodowska-Curie Actions and hosted by the University of York, aims to preserve the acoustics of four English cathedrals, which represent the diversity of this group of heritage buildings, by characterising their acoustic behaviour through impulse response measurements as well as by recreating their sound environment throughout history using computer models.
