Abstract

Par l'ajout d'un réseau de correction (7) à un dispositif formé par un transducteur (1) incorporé à un meuble bass-reflex (2) et dimensionné de façon que ce transducteur n'est pas à meme de reproduire les sons graves, il est possible de simuler un dispositif ormé par un convertisseur fictif qui, incorporé audit meuble, est par contre capable de reproduire les sons graves alors que la plage de fréquence Hf(f) du transducteur est beaucoup plus large que celle du dispositif cité en premier lieu. Application : équipement sonore de salles de spectacle.
