Abstract

L'INVENTION A POUR OBJET UN PROCEDE ET DES DISPOSITIFS ANTI-BRUIT POUR ACCELERER LE TIRAGE DES CONDUITS D'AERATION OU D'EVACUATION. UN DISPOSITIF SELON L'INVENTION POUR ACCELERER LE TIRAGE D'UN CONDUIT 2 DE HOTTE OU DE CHEMINEE 1 COMPORTE UN CONDUIT AUXILIAIRE 3 EQUIPE D'UN VENTILATEUR 6 ET D'UN EJECTEUR A AIR 7 QUI PRODUIT UN TIRAGE INDUIT DANS LE CONDUIT 2. SUR LE CONDUIT AUXILIAIRE 3 EST DISPOSE UN ABSORBEUR ACOUSTIQUE ACTIF 9 COMPORTANT UNE ENCEINTE ACOUSTIQUE EQUIPEE DE TROIS HAUT-PARLEURS FORMANT UN DIPOLE ET UN MONOPOLE ET UN COFFRET CONTENANT UN MICROPHONE PLACE AU CONTACT DU CONDUIT 3 QUI TRANSMET AUX TROIS HAUT-PARLEURS LES BRUITS DU VENTILATEUR 6. UNE APPLICATION EST LA CONSTRUCTION DE HOTTES D'ASPIRATION OU DE CHEMINEES ANTI-BRUIT A TIRAGE INDUIT.
