The aim of the invention is to provide a method for controlling work pieces that have at least one interior space, which can be easily and rapidly carried out. According to the invention, the respective method comprises the following steps: generating a gas flow in the interior space of the work piece, detecting the noise produced by said gas flow, and comparing the measured value derived from the noise with a set value.

L'invention vise à créer un procédé simple et rapide pour contrôler des pièces d'usinage comportant au moins une cavité intérieure. A cet effet, le procédé selon la présente invention consiste à générer un flux gazeux dans la cavité de la pièce d'usinage, à capter le bruit produit par le flux gazeux et à comparer une valeur de mesure résultant de ce bruit avec une valeur nominale.
