The city of Ravello and its hundreds clerical buildings. Acoustic discoveries of the St Mary Gradillo's church

Hundreds of churches and monasteries have been erected in a small town nearby Naples during the Medieval Age. A recent proposal by the local authority regards the utilization of some clerical buildings to be part of the places selected to host musical venues during the festival that is annually recurring in Ravello. The St Mary Gradillo's church has been built during the 11th century, to be composed by three naves marked by columns, following the architectural features of a basilica. The different height and typology of roof, to be a double slope in the central nave and vaulted in the lateral ones, is characterised by a dome located at the junction of the wings crossed at the level of the altar. This paper deals with the assessment of the existing acoustic conditions of the church. The evaluation is based on the analysis of the main acoustic parameters in accordance with ISO 3382-1. Measures adopted to adjust the acoustics to host musical venues have been treated in terms of additional absorbing panels other than mountable solutions for a temporary wooden stage
