Résumé
During the last decade, acoustic pots inserted into the walls and roofs of medieval and modern churches havebeen the focus of renewed scientific curiosity after a long time of relative silence. Traditionally, authors fromthe Middle Ages to the present time considered that Vitruvius established the relation between the “vasa aerea”(bronze vessels) in ancient Greek theatres and the “fictilibus doliis” (earthen vessels). Vitruvius’s text and phi-losophy is analysed with regards to acoustics, and his recommendations are compared with medieval, modernand contemporary texts about acoustic pots. Most of them hints at an acoustical purpose for the pots. Therefore,the literature survey is supplemented with an acoustical survey of 25 French churches where pots still remain.Recent measurements and observations in some those churches, completed with recent data from foreign studies,are consistent with an acoustical purpose of the pots to decrease the reverberation time at frequencies stronglyexcited by the spoken voice.
