Résumé

La modélisation par ordinateur est employe dans le concept d'un systeme (tripoles) a deux elements capabale de generer un profil car-dioide precis de radiation pour des frequences inférieures a 500 Hz. Le modele est employe pour evaluer l'efficacite des étalagés spheriques de telles tripoles afin de reduire le champs spheriques de sonorité. Un étalagé tripoles d'annulation est construit et il est trouve que son comportement suit le modele de prediction.
