Building Acoustics
Chambéry, AURA

In Chambéry, the cluse valley configuration concentrates the A41 and A43 motorways, the railway and the built-up area within a narrow corridor, which places a large part of the territory under high exposure and demands sizing façade sound insulation. The university campus and the local research establishments add a family of projects in which speech intelligibility and control of reverberation govern usability. The historic centre, whose old buildings are gradually being converted, finally presents the classic difficulties of transmission through timber floors during changes of use.

In Chambéry, 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.
