<p>The invention concerns an active device for reducing noise in an engine (10) exhaust system (12) comprising two exhaust outlets (16A, 16B). The device comprises for each exhaust outlet (16A, 16B), a particular transducer (24A, 24B) for emitting a noise reduction sound wave and at least a processing line (28) capable of generating a noise reduction signal and activating the transducers on the basis of the noise reduction signal. It comprises, for at least two exhaust outlets (16A, 16B), a single processing line (28), which processing line (28) comprises at least a processing element common to each of the exhaust outlets (16A, 16B).</p> |
