Abstract

L'invention concerne un dispositif servant à localiser des filtres défectueux dans une pluralité de filtres. Ce dispositif comprend un appareil de contrôle du son et un circuit de traitement. L'appareil de contrôle du son est associé à une pluralité de filtres afin de détecter des sons émanant de ladite pluralité et de produire des signaux de sortie indiquant ces sons. Le circuit de traitement est couplé à l'appareil de contrôle du son afin de déterminer l'emplacement des filtres défectueux dans la pluralité de filtres en fonction des signaux de sortie. Elle concerne également une sonde servant à localiser des filtres défectueux en fonction de sons émanant de ces filtres.
