Building Acoustics
Marseille, PACA

In Marseille, acoustic pressure is among the highest in the region: traffic on the A7, A50 and A55 motorways, the activity of the Grand Port Maritime, the density of the old centre and the office developments of Euroméditerranée where open-plan floors demand careful treatment of reverberation and intelligibility. Added to this are the noise exposure plan of Marseille-Provence airport (Marignane) and the railways, which demand reinforced façade sound insulation. The refurbishment of the old stock, on old separating walls rarely compliant with the NRA, and the proliferation of heat pumps in the heart of the urban block make the predictive acoustic study a structuring item from the design stage of Marseille projects.

In Marseille, 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.
