Sound damping device e.g. resonance muffler, for motor vehicle exhaust gas system, has electro acoustic transducer devices converting pressure fluctuations in exhaust gas into electrical energy, and damping unit provided for damping energy

The device has electro acoustic transducer devices that convert pressure fluctuations in exhaust gas into electrical energy. A damping unit (15) is provided for damping the electrical energy. One of the transducer devices is arranged in exhaust gas flow. The damping unit comprises of an electrical f...
