Résumé

La mesure de la transmission du son â travers l'enveloppe d'un bâtiment exige qu'on détermine la puissance acoustique incidente. La mesure directe du champ acoustique près de l'élément de surface considéré semble préférable à l'utilisation d'une 'source étalonnée' en raison de variations dans la propagation extérieure des ondes associées aux réflexions par le sol et aux conditions atmosphérique. L'interprétation des mesures du niveau de pression du son dans ces conditions est cependant rendue difficile en raison de l'interférence entre les ondes sonores incidentes et celles réfléchies par les surfaces de bâtiments. Cette communication présente les résultats expérimentaux et propose un modèle simplifié de prédiction.
