Abstract

L'invention concerne une hotte aspirante comportant : une plaque de régulation de débit (9) située au sein d'un couvercle de plaque de régulation de débit (3) et disposée face à une ouverture d'aspiration (8) ; un ventilateur (14) permettant d'évacuer l'air à l'intérieur d'un passage d'écoulement d'air (15) vers l'extérieur ; et un dispositif d'insonorisation active (20) pour estomper le bruit se propageant à travers l'intérieur du passage d'écoulement d'air (15). Le passage d'écoulement d'air (15) possède des parois de séparation (18) disposées à l'intérieur de façon à former des passages d'écoulement d'air divisés (19) situés au niveau de la partie du passage d'écoulement d'air qui s'étend de l'ouverture d'aspiration (8) au ventilateur (14) et possédant des aires en coupe transversale de flux d'air subdivisées. Un microphone d'erreur (21) pour détecter une erreur d'insonorisation et un haut-parleur (22) pour diffuser une onde sonore sont disposés sur la paroi interne (17) du côté du logement (4) du passage d'écoulement d'air divisé (19), le microphone d'erreur (21) et le haut-parleur (22) constituant le dispositif d'insonorisation active (20).
