Conclusion
Le sujet de l’acoustique des espaces de bureaux ouverts
n’est pas nouveau. Certaines connaissances ont plus de
quarante ans. Les méthodes et les outils existent et ne
demandent qu’à être validés dans des contextes différents.
Cependant, le sujet est complexe et demande à être appro-
fondi. Les avancées technologiques, tant dans le domaine
de la mesure en site que dans celui de la caractérisation
de performance, ouvrent de nouvelles perspectives pour
encore mieux comprendre, cerner et surtout répondre à
une question qui concerne un nombre croissant d’entre
nous : le confort acoustique en open space.
