Popis:	Up to now, decoupling elements are primarily used to ensure the mechanical endurance of exhaust systems. Tenneco - Heinrich Gillet GmbH, in cooperation with the Acoustic Work Group at the University of Kaiserslautern, has developed a procedure to capture the acoustic decoupling effects of these elements up to 5 kHz, enabling an evaluation of their damping efficiency of the structure-borne noise created by the exhaust-gas turbocharger. A special vibro-acoustic test bench was developed and innovative concepts for structure-borne noise isolation were worked up.
