Abstract not available for EP1282895 Abstract of corresponding document: US2004086136 The invention relates to an electroaeroacoustic source (2) placed in a flow (V) or at the edge of a flow, consisting of an electrodynamic or electromagnetic motor means (5) generating an oscillating motion, and an element (3) coupled to the motor means (5) obstructing the flow so as to exert a dynamic action on said flow. This source can be used to produce an electroaeroacoustic system for the active noise control, particularly in a confined flow.
