Building Acoustics
Bayonne, New Aquitaine

In Bayonne, at the heart of the Basque conurbation of Bayonne-Anglet-Biarritz, the tight coastal property market, the strong hotel and tourist activity and the density of the old centre concentrate the acoustic issues. The close party walls, the comfort requirements of residences and hotels, and the structuring routes (A63, railways) demand appropriate façade sound insulation. The proliferation of heat pumps on façades and roofs makes neighbourhood noise emergence critical. An acoustic study from the earliest sketch secures the insulation, equipment acoustics and the NRA compliance of Bayonne projects.

In Bayonne, 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.
