Building Acoustics
Paris, Île-de-France

In Paris, the densest and most constrained market in France, the heavy refurbishment of the Haussmann-era and post-war stock, storey additions, changes of use (office to housing) and the Grand Paris operations concentrate extreme acoustic issues: close party walls, old separating walls non-compliant with the NRA, noisy premises at the foot of buildings and high exposure to road and rail noise. The density of technical equipment (heat pumps, HVAC, mechanical ventilation) in courtyards and on roofs makes neighbourhood noise emergence critical. An acoustic study from the design stage secures the insulation, equipment acoustics and the works completion certificate of Paris projects.

In Paris, 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.
