Abstract
The present invention relates to an exhaust grille (). The exhaust grille comprises an array comprising an array of spaced vanes () which define a plurality of separate non-linear air flow passages () through the grille. The grill is configured so as to deflect sound waves incident upon the grille to prevent them from passing through the passages. Various configurations of exhaust grille are disclosed, and the exhaust grille configuration reduces the noise levels permitted to pass through the grille, for example when placed over an exhaust (), such as over the exhaust outlet of a vacuum cleaner.
