Building Acoustics
Perpignan, Occitania

In Perpignan, acoustic design contends with the tramontane, whose frequency and intensity govern the choice of joinery and air inlets, and with a dense logistics fabric around the Saint-Charles market, where heavy-goods traffic and refrigeration units run continuously. The old centre, engaged in a vast requalification programme, concentrates buildings with timber structures and lightweight floors whose impact sound insulation must be entirely reworked. On the coast, hotels and tourist residences impose contractual targets above regulatory requirements. Our study sets these targets before the preliminary design stage and verifies that they are met at handover.

In Perpignan, 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.
