Building Acoustics
Béziers, Occitania

In Béziers, projects mainly involve refurbishing the old centre under the Action Cœur de Ville programme, where converting old buildings into housing requires rebuilding compliant separating walls on existing timber floors. The winegrowing fabric adds a specific family of projects, the wineries and cooperative cellars, whose refrigeration and process equipment constitute sources at the property boundary to be treated under neighbourhood noise rules. The A9 and A75 infrastructure and the noise exposure plan of Béziers-Cap d'Agde airport also demand reinforced façade sound insulation across part of the built-up area.

In Béziers, 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.
