Based on the model of the church of Jesus in Rome, emblematic building of Jesuit art that served as a model for many Jesuit churches, the Jesuits Chapel of Saint-Omer was built between 1615 and 1640.
After many restoration works, the last of which date from the late nineteenth century, the Urban Planning and Development Agency of the Region of Saint-Omer realized, as part of the study for the renovation of the building, a quality event program. The renovated venue should be able to host concerts, exhibitions, indoor markets, seminars and gala dinners. Several architectural, scenic and acoustic scenarios are envisaged.
From an acoustic point of view, the Jesuit Chapel is a very reverberant sound space, due to its large volume and the low acoustic absorption of its surfaces. Such a large reverberation time is generally not favorable to the intelligibility of sound messages in the context of the planned program. Solutions to reduce the reverberation of the room are studied while respecting the heritage quality of the building.
