Building Acoustics
Avignon, PACA

In Avignon, acoustics is handled under a twofold constraint: an intra-muros centre listed as World Heritage, where the Architecte des Bâtiments de France governs any intervention on the façade, and an old building fabric whose separating walls are rarely compliant with acoustic regulations when converted into housing. Added to this are the performance and broadcast venues, numerous and active around the festival, which call for treatment of reverberation and airborne sound insulation, and the nuisance from the ring boulevards and the Courtine logistics platform. The predictive acoustic study arbitrates these requirements from the earliest sketch, while insulation solutions remain compatible with the protected envelope.

In Avignon, urban density, the widespread use of outdoor heat pumps and neighbourhood noise nuisance make the acoustic study decisive: from the design stage, to size the sound insulation and avoid disputes at handover, then at acceptance, to certify NRA compliance and regulatory noise emergence.
